AngularJS: API: ng/directive


Directive components in ng

名称 描述
ngApp

Use this directive to auto-bootstrap an AngularJS application. The ngApp directive designates the root element of the application and is typically placed near the root element of the page -例如 on the <body> or <html> tags.

a

Modifies the default behavior of the html A tag so that the default action is prevented when the href attribute is empty.

ngHref

Using Angular markup like {{hash}} in an href attribute will make the link go to the wrong URL if the user clicks it before Angular has a chance to replace the {{hash}} markup with its value. Until Angular replaces the markup the link will be broken and will most likely return a 404 error.

ngSrc

Using Angular markup like {{hash}} in a src attribute doesn't work right: The browser will fetch from the URL with the literal text {{hash}} until Angular replaces the expression inside {{hash}}. The ngSrc directive solves this problem.

ngSrcset

Using Angular markup like {{hash}} in a srcset attribute doesn't work right: The browser will fetch from the URL with the literal text {{hash}} until Angular replaces the expression inside {{hash}}. The ngSrcset directive solves this problem.

ngDisabled

The following markup will make the button enabled on Chrome/Firefox but not on IE8 and older IEs:

<div ng-init="scope = { isDisabled: false }">
 <button disabled="{{scope.isDisabled}}">Disabled</button>
</div>
ngChecked

HTML规范不要求浏览器对布尔型属性必须给出值,例如checked(它们存在表示true,不存在表示false)。 如果我们放置了一个Angular动态表达式到这样的属性上,在浏览器删除属性时绑定信息将会丢失。 The ngChecked directive solves this problem for the checked attribute. 这个指令不会被浏览器删除,并提供了一个永久的可靠的地方存放绑定信息。

ngReadonly

HTML规范不要求浏览器对布尔型属性必须给出值,例如readonly(它们存在表示true,不存在表示false)。 如果我们放置了一个Angular动态表达式到这样的属性上,在浏览器删除属性时绑定信息将会丢失。 The ngReadonly directive solves this problem for the readonly attribute. 这个指令不会被浏览器删除,并提供了一个永久的可靠的地方存放绑定信息。

ngSelected

HTML规范不要求浏览器对布尔型属性必须给出值,例如selected(它们存在表示true,不存在表示false)。 如果我们放置了一个Angular动态表达式到这样的属性上,在浏览器删除属性时绑定信息将会丢失。 The ngSelected directive solves this problem for the selected attribute. 这个指令不会被浏览器删除,并提供了一个永久的可靠的地方存放绑定信息。

ngOpen

HTML规范不要求浏览器对布尔型属性必须给出值,例如open(它们存在表示true,不存在表示false)。 如果我们放置了一个Angular动态表达式到这样的属性上,在浏览器删除属性时绑定信息将会丢失。 The ngOpen directive solves this problem for the open attribute. 这个指令不会被浏览器删除,并提供了一个永久的可靠的地方存放绑定信息。

ngForm

可嵌套的form指令别名。HTML不允许form元素嵌套。 It is useful to nest forms, for example if the validity of a sub-group of controls needs to be determined.

form

Directive that instantiates FormController.

textarea

HTML textarea element control with angular data-binding. The data-binding and validation properties of this element are exactly the same as those of the input element.

input

HTML input element control with angular data-binding. Input control follows HTML5 input types and polyfills the HTML5 validation behavior for older browsers.

ngModel

The ngModel directive binds an input,select, textarea (or custom form control) to a property on the scope using NgModelController, which is created and exposed by this directive.

ngChange

Evaluate the given expression when the user changes the input. The expression is evaluated immediately, unlike the JavaScript onchange event which only triggers at the end of a change (usually, when the user leaves the form element or presses the return key). The expression is not evaluated when the value change is coming from the model.

ngList

Text input that converts between a delimited string and an array of strings. The delimiter can be a fixed string (by default a comma) or a regular expression.

ngValue

Binds the given expression to the value of input[select] or input[radio], so that when the element is selected, the ngModel of that element is set to the bound value.

ngModelOptions

Allows tuning how model updates are done. Using ngModelOptions you can specify a custom list of events that will trigger a model update and/or a debouncing delay so that the actual update only takes place when a timer expires; this timer will be reset after another change takes place.

ngBind

The ngBind attribute tells Angular to replace the text content of the specified HTML element with the value of a given expression, and to update the text content when the value of that expression changes.

ngBindTemplate

The ngBindTemplate directive specifies that the element text content should be replaced with the interpolation of the template in the ngBindTemplate attribute. Unlike ngBind, the ngBindTemplate can contain multiple {{ }} expressions. This directive is needed since some HTML elements (such as TITLE and OPTION) cannot contain SPAN elements.

ngBindHtml

Creates a binding that will innerHTML the result of evaluating the expression into the current element in a secure way. 默认情况下, the innerHTML-ed content will be sanitized using the $sanitize service. To utilize this functionality, ensure that $sanitize is available, 例如,by including ngSanitize in your module's dependencies (not in core Angular.) You may also bypass sanitization for values you know are safe. To do so, bind to an explicitly trusted value via $sce.trustAsHtml. See the example under Strict Contextual Escaping (SCE).

ngClass

The ngClass directive allows you to dynamically set CSS classes on an HTML element by databinding an expression that represents all classes to be added.

ngClassOdd

The ngClassOdd and ngClassEven directives work exactly as ngClass, except they work in conjunction with ngRepeat and take effect only on odd (even) rows.

ngClassEven

The ngClassOdd and ngClassEven directives work exactly as ngClass, except they work in conjunction with ngRepeat and take effect only on odd (even) rows.

ngCloak

The ngCloak directive is used to prevent the Angular html template from being briefly displayed by the browser in its raw (uncompiled) form while your application is loading. Use this directive to avoid the undesirable flicker effect caused by the html template display.

ngController

The ngController directive attaches a controller class to the view. This is a key aspect of how angular supports the principles behind the Model-View-Controller design pattern.

ngCsp

Enables CSP (Content Security Policy) support.

ngClick

The ngClick directive allows you to specify custom behavior when an element is clicked.

ngDblclick

The ngDblclick directive allows you to 指定自定义行为到a dblclick事件上。

ngMousedown

The ngMousedown directive allows you to 指定自定义行为到mousedown事件上。

ngMouseup

指定自定义行为到mouseup事件上。

ngMouseover

指定自定义行为到mouseover事件上。

ngMouseenter

指定自定义行为到mouseenter事件上。

ngMouseleave

指定自定义行为到mouseleave事件上。

ngMousemove

指定自定义行为到mousemove事件上。

ngKeydown

指定自定义行为到keydown事件上。

ngKeyup

指定自定义行为到keyup事件上。

ngKeypress

指定自定义行为到keypress事件上。

ngSubmit

Enables binding Angular表达式s to onsubmit events.

ngFocus

指定自定义行为到focus事件上。

ngBlur

指定自定义行为到blur事件上。

ngCopy

指定自定义行为到copy事件上。

ngCut

为剪切事件指定自定义行为。

ngPaste

指定自定义行为到paste事件上。

ngIf

The ngIf directive removes or recreates a portion of the DOM tree based on an {expression}. If the expression assigned to ngIf evaluates to a false value then the element is removed from the DOM, otherwise a clone of the element is reinserted into the DOM.

ngInclude

Fetches, compiles and includes an external HTML fragment.

ngInit

The ngInit directive allows you to evaluate an expression in the current scope.

ngNonBindable

The ngNonBindable directive tells Angular not to compile or bind the contents of the current DOM element. This is useful if the element contains what appears to be Angular directives and bindings but which should be ignored by Angular. This could be the case if you have a site that displays snippets of code, for instance.

ngPluralize

ngPluralize is a directive that displays messages according to en-US localization rules. These rules are bundled with angular.js, but can be overridden (see Angular i18n dev guide). You configure ngPluralize directive by specifying the mappings between 多元化条目 and the strings to be displayed.

ngRepeat

The ngRepeat directive instantiates a template once per item from a collection. Each template instance gets its own scope, where the given loop variable is set to the current collection item, and $index is set to the item index or key.

ngShow

The ngShow directive shows or hides the given HTML element based on the expression provided to the ngShow attribute. The element is shown or hidden by removing or adding the ng-hide CSS class onto the element. The .ng-hide CSS class is predefined in AngularJS and sets the display style to none (using an !important flag). For CSP mode please add angular-csp.css to your html file (see ngCsp).

ngHide

The ngHide directive shows or hides the given HTML element based on the expression provided to the ngHide attribute. The element is shown or hidden by removing or adding the ng-hide CSS class onto the element. The .ng-hide CSS class is predefined in AngularJS and sets the display style to none (using an !important flag). For CSP mode please add angular-csp.css to your html file (see ngCsp).

ngStyle

The ngStyle directive allows you to set CSS style on an HTML element conditionally.

ngSwitch

The ngSwitch directive is used to conditionally swap DOM structure on your template based on a scope expression. Elements within ngSwitch but without ngSwitchWhen or ngSwitchDefault directives will be preserved at the location as specified in the template.

ngTransclude

Directive that marks the insertion point for the transcluded DOM of the nearest parent directive that uses transclusion.

script

Load the content of a <script> element into $templateCache, so that the template can be used by ngInclude, ngView, or directives. The type of the <script> element must be specified as text/ng-template, and a cache name for the template must be assigned through the element's id, which can then be used as a directive's templateUrl.

select

HTML SELECT element with angular data-binding.
