* @ngdoc input
* @name input[text]
*
* @description
* Standard HTML text input with AngularJS data binding, inherited by most of the `input` elements.
*
*
* @param {string} ngModel Assignable AngularJS expression to data-bind to.
* @param {string=} name Property name of the form under which the control is published.
* @param {string=} required Adds `required` validation error key if the value is not entered.
* @param {string=} ngRequired Adds `required` attribute and `required` validation constraint to
* the element when the ngRequired expression evaluates to true. Use `ngRequired` instead of
* `required` when you want to data-bind to the `required` attribute.
* @param {number=} ngMinlength Sets `minlength` validation error key if the value is shorter than
* minlength.
* @param {number=} ngMaxlength Sets `maxlength` validation error key if the value is longer than
* maxlength. Setting the attribute to a negative or non-numeric value, allows view values of
* any length.
* @param {string=} pattern Similar to `ngPattern` except that the attribute value is the actual string
* that contains the regular expression body that will be converted to a regular expression
* as in the ngPattern directive.
* @param {string=} ngPattern Sets `pattern` validation error key if the ngModel {@link ngModel.NgModelController#$viewValue $viewValue}
* does not match a RegExp found by evaluating the AngularJS expression given in the attribute value.
* If the expression evaluates to a RegExp object, then this is used directly.
* If the expression evaluates to a string, then it will be converted to a RegExp
* after wrapping it in `^` and `$` characters. For instance, `"abc"` will be converted to
* `new RegExp('^abc$')`.<br />
* **Note:** Avoid using the `g` flag on the RegExp, as it will cause each successive search to
* start at the index of the last search's match, thus not taking the whole input value into
* account.
* @param {string=} ngChange AngularJS expression to be executed when input changes due to user
* interaction with the input element.
* @param {boolean=} [ngTrim=true] If set to false AngularJS will not automatically trim the input.
* This parameter is ignored for input[type=password] controls, which will never trim the
* input.

* @ngdoc input

* Input with date validation and transformation. In browsers that do not yet support
* the HTML5 date input, a text element will be used. In that case, text must be entered in a valid ISO-8601
* date format (yyyy-MM-dd), for example: `2009-01-06`. Since many
* modern browsers do not yet support this input type, it is important to provide cues to users on the
* expected input format via a placeholder or label.
*
* The model must always be a Date object, otherwise AngularJS will throw an error.
* Invalid `Date` objects (dates whose `getTime()` is `NaN`) will be rendered as an empty string.
*
* The timezone to be used to read/write the `Date` instance in the model can be defined using
* {@link ng.directive:ngModelOptions ngModelOptions}. By default, this is the timezone of the browser.
*
* @param {string} ngModel Assignable AngularJS expression to data-bind to.
* @param {string=} name Property name of the form under which the control is published.
* @param {string=} min Sets the `min` validation error key if the value entered is less than `min`. This must be a
* valid ISO date string (yyyy-MM-dd). You can also use interpolation inside this attribute
* (e.g. `min="{{minDate | date:'yyyy-MM-dd'}}"`). Note that `min` will also add native HTML5
* constraint validation.
* @param {string=} max Sets the `max` validation error key if the value entered is greater than `max`. This must be
* a valid ISO date string (yyyy-MM-dd). You can also use interpolation inside this attribute
* (e.g. `max="{{maxDate | date:'yyyy-MM-dd'}}"`). Note that `max` will also add native HTML5
* constraint validation.
* @param {(date|string)=} ngMin Sets the `min` validation constraint to the Date / ISO date string
* the `ngMin` expression evaluates to. Note that it does not set the `min` attribute.
* @param {(date|string)=} ngMax Sets the `max` validation constraint to the Date / ISO date string
* the `ngMax` expression evaluates to. Note that it does not set the `max` attribute.
* @param {string=} required Sets `required` validation error key if the value is not entered.
* @param {string=} ngRequired Adds `required` attribute and `required` validation constraint to
* the element when the ngRequired expression evaluates to true. Use `ngRequired` instead of

* @description
* Input with month validation and transformation. In browsers that do not yet support
* the HTML5 month input, a text element will be used. In that case, the text must be entered in a valid ISO-8601
* month format (yyyy-MM), for example: `2009-01`.
*
* The model must always be a Date object, otherwise AngularJS will throw an error.
* Invalid `Date` objects (dates whose `getTime()` is `NaN`) will be rendered as an empty string.
* If the model is not set to the first of the month, the next view to model update will set it
* to the first of the month.
*
* The timezone to be used to read/write the `Date` instance in the model can be defined using
* {@link ng.directive:ngModelOptions ngModelOptions}. By default, this is the timezone of the browser.
*
* @param {string} ngModel Assignable AngularJS expression to data-bind to.
* @param {string=} name Property name of the form under which the control is published.
* @param {string=} min Sets the `min` validation error key if the value entered is less than `min`.
* This must be a valid ISO month format (yyyy-MM). You can also use interpolation inside this
* attribute (e.g. `min="{{minMonth | date:'yyyy-MM'}}"`). Note that `min` will also add
* native HTML5 constraint validation.
* @param {string=} max Sets the `max` validation error key if the value entered is greater than `max`.
* This must be a valid ISO month format (yyyy-MM). You can also use interpolation inside this
* attribute (e.g. `max="{{maxMonth | date:'yyyy-MM'}}"`). Note that `max` will also add
* native HTML5 constraint validation.
* @param {(date|string)=} ngMin Sets the `min` validation constraint to the Date / ISO week string
* the `ngMin` expression evaluates to. Note that it does not set the `min` attribute.
* @param {(date|string)=} ngMax Sets the `max` validation constraint to the Date / ISO week string
* the `ngMax` expression evaluates to. Note that it does not set the `max` attribute.
* @param {string=} required Sets `required` validation error key if the value is not entered.
* @param {string=} ngRequired Adds `required` attribute and `required` validation constraint to
* the element when the ngRequired expression evaluates to true. Use `ngRequired` instead of
* `required` when you want to data-bind to the `required` attribute.
* @param {string=} ngChange AngularJS expression to be executed when input changes due to user

* ### HTML5 constraint validation and `allowInvalid`
*
* In browsers that follow the
* [HTML5 specification](https://html.spec.whatwg.org/multipage/forms.html#number-state-%28type=number%29),
* `input[number]` does not work as expected with {@link ngModelOptions `ngModelOptions.allowInvalid`}.
* If a non-number is entered in the input, the browser will report the value as an empty string,
* which means the view / model values in `ngModel` and subsequently the scope value
* will also be an empty string.
*
* @knownIssue
*
* ### Large numbers and `step` validation
*
* The `step` validation will not work correctly for very large numbers (e.g. 9999999999) due to
* Javascript's arithmetic limitations. If you need to handle large numbers, purpose-built
* libraries (e.g. https://github.com/MikeMcl/big.js/), can be included into AngularJS by
* {@link guide/forms#modifying-built-in-validators overwriting the validators}
* for `number` and / or `step`, or by {@link guide/forms#custom-validation applying custom validators}
* to an `input[text]` element. The source for `input[number]` type can be used as a starting
* point for both implementations.

* @ngdoc input
* @name input[range]
*
* @description
* Native range input with validation and transformation.
*
* The model for the range input must always be a `Number`.
*
* IE9 and other browsers that do not support the `range` type fall back
* to a text input without any default values for `min`, `max` and `step`. Model binding,
* validation and number parsing are nevertheless supported.
*
* Browsers that support range (latest Chrome, Safari, Firefox, Edge) treat `input[range]`
* in a way that never allows the input to hold an invalid value. That means:
* - any non-numerical value is set to `(max + min) / 2`.
* - any numerical value that is less than the current min val, or greater than the current max val
* is set to the min / max val respectively.
* - additionally, the current `step` is respected, so the nearest value that satisfies a step
* is used.
*
* See the [HTML Spec on input[type=range]](https://www.w3.org/TR/html5/forms.html#range-state-(type=range))
* for more info.
*
* This has the following consequences for AngularJS:
*
* Since the element value should always reflect the current model value, a range input
* will set the bound ngModel expression to the value that the browser has set for the
* input element. For example, in the following input `<input type="range" ng-model="model.value">`,
* if the application sets `model.value = null`, the browser will set the input to `'50'`.
* AngularJS will then set the model to `50`, to prevent input and model value being out of sync.
*
* That means the model for range will immediately be set to `50` after `ngModel` has been
* initialized. It also means a range input can never have the required error.
*
* This does not only affect changes to the model value, but also to the values of the `min`,
* `max`, and `step` attributes. When these change in a way that will cause the browser to modify
* the input value, AngularJS will also update the model value.
*
* Automatic value adjustment also means that a range input element can never have the `required`,
* `min`, or `max` errors.
*
* However, `step` is currently only fully implemented by Firefox. Other browsers have problems
* when the step value changes dynamically - they do not adjust the element value correctly, but
* instead may set the `stepMismatch` error. If that's the case, the AngularJS will set the `step`
* error on the input, and set the model to `undefined`.
*
* Note that `input[range]` is not compatible with`ngMax`, `ngMin`, and `ngStep`, because they do
* not set the `min` and `max` attributes, which means that the browser won't automatically adjust
* the input value based on their values, and will always assume min = 0, max = 100, and step = 1.

* @description
* HTML textarea element control with AngularJS data-binding. The data-binding and validation
* properties of this element are exactly the same as those of the
* {@link ng.directive:input input element}.
*
* @param {string} ngModel Assignable AngularJS expression to data-bind to.
* @param {string=} name Property name of the form under which the control is published.
* @param {string=} required Sets `required` validation error key if the value is not entered.
* @param {string=} ngRequired Adds `required` attribute and `required` validation constraint to
* the element when the ngRequired expression evaluates to true. Use `ngRequired` instead of
* `required` when you want to data-bind to the `required` attribute.
* @param {number=} ngMinlength Sets `minlength` validation error key if the value is shorter than
* minlength.
* @param {number=} ngMaxlength Sets `maxlength` validation error key if the value is longer than
* maxlength. Setting the attribute to a negative or non-numeric value, allows view values of any
* length.
* @param {string=} ngPattern Sets `pattern` validation error key if the ngModel {@link ngModel.NgModelController#$viewValue $viewValue}
* does not match a RegExp found by evaluating the AngularJS expression given in the attribute value.
* If the expression evaluates to a RegExp object, then this is used directly.
* If the expression evaluates to a string, then it will be converted to a RegExp
* after wrapping it in `^` and `$` characters. For instance, `"abc"` will be converted to
* `new RegExp('^abc$')`.<br />
* **Note:** Avoid using the `g` flag on the RegExp, as it will cause each successive search to
* start at the index of the last search's match, thus not taking the whole input value into
* account.
* @param {string=} ngChange AngularJS expression to be executed when input changes due to user
* interaction with the input element.
* @param {boolean=} [ngTrim=true] If set to false AngularJS will not automatically trim the input.
*
* @knownIssue
*
* When specifying the `placeholder` attribute of `<textarea>`, Internet Explorer will temporarily
* insert the placeholder value as the textarea's content. If the placeholder value contains
* interpolation (`{{ ... }}`), an error will be logged in the console when AngularJS tries to update
* the value of the by-then-removed text node. This doesn't affect the functionality of the
* textarea, but can be undesirable.
*
* You can work around this Internet Explorer issue by using `ng-attr-placeholder` instead of
* `placeholder` on textareas, whenever you need interpolation in the placeholder value. You can
* find more details on `ngAttr` in the
* [Interpolation](guide/interpolation#-ngattr-for-binding-to-arbitrary-attributes) section of the
* Developer Guide.
