Javascript 使用 JQuery 将 onclick 属性添加到 <a> 标签

Adding onclick Attribute to <a> tag using JQuery

提问by Joseph Ghassan

I have a link button that I want to change it onclickcallback function when clicked:

我有一个链接按钮，我想onclick在单击时更改它的回调函数：

I am using .attr()to change the onclickevent but it simply doesn't work.

我正在使用.attr()更改onclick事件，但它根本不起作用。

$('#' + test).text('Unlike');
$('#' + test).attr("onclick", "return deleteLikeComment('"
        + CommentsWrapper + "','" + activityID + "', '" + test + "');");

But it simply doesn't work.

但这根本行不通。

I just want to switch the callback method when the link is clicked.

我只想在点击链接时切换回调方法。

Why are you attaching the event with an attr?

你为什么用 attr 附加事件？

Why not just do like so:

为什么不这样做：

$('#' + test).bind("click", function()
{
    //functionality that you were trying to add using attr can now go inside here.
});

$('#' + test).click(function() {
    return deleteLikeComment(...);
});

Use "click()" instead of attr()

使用“ click()”代替attr()

If you want to switch the callback method every time the link is clicked, use .toggle(). It alternates between the two provided functions.

如果要在每次点击链接时切换回调方法，请使用.toggle(). 它在提供的两个功能之间交替。
