如何以编程方式触发 ngClick

angular.element(domElement).triggerHandler('click');

EDIT: It appears that you have to break out of the current $apply() cycle. One way to do this is using $timeout():

$timeout(function() {
angular.element(domElement).triggerHandler('click');
}, 0);

See fiddle: http://jsfiddle.net/t34z7/

You can do like

$timeout(function() {
angular.element('#btn2').triggerHandler('click');
});

The syntax is the following:

function clickOnUpload() {
$timeout(function() {
angular.element('#myselector').triggerHandler('click');
});
};


// Using Angular Extend
angular.extend($scope, {
clickOnUpload: clickOnUpload
});


// OR Using scope directly
$scope.clickOnUpload = clickOnUpload;

More info on Angular Extend way here.

If you are using old versions of angular, you should use trigger instead of triggerHandler.

If you need to apply stop propagation you can use this method as follows:

<a id="myselector" ng-click="clickOnUpload(); $event.stopPropagation();">
Something
</a>

Just in case everybody see's it, I added additional duplicating answer with an important line which will not break event propagation

$scope.clickOnUpload = function ($event) {
$event.stopPropagation(); // <-- this is important


$timeout(function() {
angular.element(domElement).trigger('click');
}, 0);
};

This following solution works for me :

angular.element(document.querySelector('#myselector')).click();

instead of :

angular.element('#myselector').triggerHandler('click');

The best solution is to use:

domElement.click()

Because the angularjs triggerHandler(angular.element(domElement).triggerHandler('click')) click events does not bubble up in the DOM hierarchy, but the one above does - just like a normal mouse click.

Using plain old JavaScript worked for me:
document.querySelector('#elementName').click();

This code will not work (throw an error when clicked):

$timeout(function() {
angular.element('#btn2').triggerHandler('click');
});

You need to use the querySelector as follows:

$timeout(function() {
angular.element(document.querySelector('#btn2')).triggerHandler('click');
});

Include following line in your method there you want to trigger click event

angular.element('#btn_you_want_to_click_progmaticallt').triggerHandler('click');
});

Simple sample:

HTML

<div id='player'>
<div id="my-button" ng-click="someFuntion()">Someone</div>
</div>

JavaScript

$timeout(function() {
angular.element('#my-button').triggerHandler('click');
}, 0);

What this does is look for the button's id and perform a click action. Voila.
