jQuery attr('onclick')
提问by Shark
I'am trying to change "onclick" attribute in jQuery but it doesn't change, here is my code:
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：
$('#stop').click(function() {
$('next').attr('onclick','stopMoving()');
}
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".
我有一个 id="stop" 的元素，当用户点击它时，我想更改 id="next" 元素的 onclick 属性。
If someone knows where is the solution please help!
如果有人知道解决方案在哪里，请帮助！

Do it the jQuery way (and fix the errors):
以 jQuery 方式执行（并修复错误）：
$('#stop').click(function() {
$('#next').click(stopMoving);
// ^-- missing #
}); // <-- missing );
If the element already has a clickhandler attached via the onclickattribute, you have to remove it:
如果元素已经click通过onclick属性附加了处理程序，则必须将其删除：
$('#next').attr('onclick', '');
Update:As @Drackir pointed out, you might also have to call $('#next').unbind('click');in order to remove other click handlers attached via jQuery.
更新：正如@Drackir 指出的那样，您可能还需要调用$('#next').unbind('click');以删除通过 jQuery 附加的其他点击处理程序。
But this is guessing here. As always: More information => better answers.
但这是在这里猜测。一如既往：更多信息 => 更好的答案。

As @Richard pointed out above, the onClick needs to have a capital 'C'.
正如@Richard 上面指出的，onClick 需要有一个大写的“C”。
$('#stop').click(function() {
$('next').attr('onClick','stopMoving()');
}

The easyest way is to change .attr() function to a javascript function .setAttribute()
最简单的方法是将 .attr() 函数更改为 javascript 函数 .setAttribute()
$('#stop').click(function() {
$('next')[0].setAttribute('onclick','stopMoving()');
}

Felix Kling's way will work, (actually beat me to the punch), but I was also going to suggest to use
Felix Kling 的方法行得通，（实际上打我一拳），但我也打算建议使用
$('#next').die().live('click', stopMoving);
$('#next').die().live('click', stopMoving);
this might be a better way to do it if you run into problems and strange behaviors when the element is clicked multiple times.
如果多次单击元素时遇到问题和奇怪的行为，这可能是一种更好的方法。
