How to trigger ngClick programmatically

问题

I want to trigger ng-click of an element at runtime like:

_ele.click();

_ele.trigger('click', function());

How can this be done?

回答1:

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>

回答2:

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);

This following solution works for me :

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

instead of :

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

回答4:

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);
};

回答5:

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

回答6:

You can do like

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

回答7:

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.

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.

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');
});
