单击以ajax生成的“ a”元素

Question

Can't execute click() on generated ajax a element. But I can select.

function cansel(){
    var cansel_button = document.getElementById('cansel_button');
    console.log(cansel_button);
    console.log('post');
    cansel_button.click();
}

And I got this log:

<a id=​"cansel_button" style=​"text-decoration:​none;​" class="" onclick="">​…​</a>​
post
extensions/event.js:185Error in event handler for 'undefined': TypeError: Object  has no method 'click'
    at cansel (unknown source)
    at unknown source
    at [object Object].dispatch (extensions/event.js:183:28)
    at Object.<anonymous> (extensions/miscellaneous_bindings.js:177:22)

And yes, this is injected script from chrome extension.

UPD: Injected page have trigger like $('#element').live('click', function(){ }) and I need to execute this without any hacks.

Answer 1

document.getElementById method returns DOM Element , which does not have "click" method you were trying to call. If you want to call click handler, then you need to use this:

 cansel_button.onclick();

instead of cansel_button.click(); .
