jQuery通过链接为li分配onclick [英] jquery assign onclick for li from a link

问题描述

我有一个物品清单

<ul class="list">
    <li>
        <a href="#Course1" class="launch" onclick="alert('event 1')">event 1</a>
    </li>
    <li class="alt">
        <a href="#Course2" class="launch" onclick="alert('event 2')">event 2</a>
    </li>
    <li>
        <a href="#Course3" class="launch" onclick="alert('event 3')">event 3</a>
    </li>
    <li class="alt">
        <a href="#Course4" class="launch" onclick="alert('event 4')">event 4</a>
    </li>
</ul>

我希望也可以将链接的onclick分配给li的onclick

I want to be able to assign the onclick of the link to the onclick of the li aswell

到目前为止，我的尝试是落后一击(因为我是将脚本分配给onclick而不是执行脚本)

My attempt so far is one click behind (as I am assigning the script to the onclick rather than executing the script)

$('.list li').click(function() {
    var launch = $('a.launch', this);
    if (launch.size() > 0) { this.onclick = launch.attr('onclick'); }
});

先谢谢了 蒂姆

推荐答案

基于 @Thomas Stock's answer 以下代码可防止在单击时重复执行链接代替李. (从此处 jQuery网站获取它)

building on @Thomas Stock's answer the following code prevents double execution on clicking on link instead of li. (got it from here jQuery site)

$(document).ready(function() {

    $('ul.list li').click(function(e) {
        var $target = $(e.target);
        if(!$target.is("li")) //magic happens here!!
        {
            return;
        }

        var launch = $('a.launch', this);
        if (launch.size() > 0) 
        { 
          eval(launch[0].onclick());
        }
    });
});
