我想在 onclick 发生时发送两个 id，就像现在单击 div 2 时一样我也想只传递第二个 div 的 id，然后为第二个 div 编写脚本。是否可以？如果是这样，那怎么办？任何例子？
<div id="1st_div"></div>
<div id="2nd_div">
<div id="inner_of_2nd_div" onclick="myfunction('1st_div')"></div>
</div>

You can pass as many parameters as you wish. Just define the function accordingly.
您可以根据需要传递任意数量的参数。只需相应地定义函数。
For instance, for a 2 parameters function myFunction, your onclick should look like
例如，对于 2 个参数的函数 myFunction，您的 onclick 应该如下所示
onclick="myfunction(p1, p2)"
and your function myFunction like
和你的功能 myFunction 像
myfunction(p1, p2) {
//do your stuff
}

I understand that you want a function which has id argument of the clicked div. If right, use JQuery and do that:
我知道您想要一个具有被点击 div 的 id 参数的函数。如果正确，请使用 JQuery 并执行以下操作：
HTML:
HTML：
<script src="http://code.jquery.com/jquery-1.11.3.min.js"/>
<div id="1st_div" class="clickable"></div>
<div id="2nd_div" class="clickable">
<div id="inner_of_2nd_div" ></div>
</div>
JS Jquery:
JS 查询：
$(".clickable").click(function(){
var _id=$(this).attr("id");
alert("I am div id="+_id+" and I've been clicked right now!");
});

<div id="inner_of_2nd_div" onclick="myfunction(document.getElementById('1st_div'));">asa</div>
<script>
function myfunction(obj)
{
//here i caught the object
obj.innerHTML=obj.id;
