jQuery attr('onclick') [英] jQuery attr('onclick')

问题描述

我正在尝试更改jQuery中的"onclick"属性，但它没有改变，这是我的代码:

I'am trying to change "onclick" attribute in jQuery but it doesn't change, here is my code:

$('#stop').click(function() {
     $('next').attr('onclick','stopMoving()');
}

我有一个id ="stop"的元素，当用户单击它时，我想更改id ="next"的元素的onclick属性.

I have an element with id="stop" and when user clicks on it I want to change an onclick attribute on element which has id="next".

如果有人知道解决方案在哪里，请帮忙！

If someone knows where is the solution please help!

推荐答案

使用jQuery方法(并修复错误):

Do it the jQuery way (and fix the errors):

$('#stop').click(function() {
     $('#next').click(stopMoving);
     // ^-- missing #
});  // <-- missing );

如果元素已经通过onclick属性附加了click处理程序，则必须将其删除:

If the element already has a click handler attached via the onclick attribute, you have to remove it:

$('#next').attr('onclick', '');

更新:正如@Drackir指出的那样，您可能还必须调用$('#next').unbind('click');才能删除通过jQuery附加的其他点击处理程序.

Update: As @Drackir pointed out, you might also have to call $('#next').unbind('click'); in order to remove other click handlers attached via jQuery.

但这是猜测.与往常一样:更多信息=>更好的答案.

But this is guessing here. As always: More information => better answers.
