示例基于此答案https://stackoverflow.com/a/7132830/2465936
以下是工作示例http://jsfiddle.net/rigaconnect/aGWGn/3/
如果点击<p id ="2310">click here to set variable to 2310</p>
然后在<div id="load"></div>
中显示2310
。
或myVariable=targ.id;
成为点击元素的id=
。
这是代码
function whichElement(e) {
var targ;
if (!e) {
var e=window.event;
}
if (e.target) {
targ=e.target;
}
else if (e.srcElement) {
targ=e.srcElement;
}
if (targ.nodeType==3) {// defeat Safari bug
targ = targ.parentNode;
}
myVariable=targ.id;
document.getElementById("load").innerHTML=myVariable;
}
<body id="-1" onmousedown="whichElement(event)">
<p id="3.14">click here to set variable to 3.14</p>
<h3 id="5">click here to set variable to 5</h3>
<p id ="2">click here to set variable to 2</p>
<p id ="2310">click here to set variable to 2310</p>
<div id="load"></div>
需要获得以下行为:
如果点击<p id ="2310">click here to set variable to 2310</p>
然后在<div id="load"></div>
中显示click here to set variable to 2310
。
或myVariable=targ.id;
值是点击文字。
理解需要这样的东西
``var myVariable = $(&#34;#??? clicked id ????&#34;)。text();`
但是不明白如何在代码中正确实现它
请咨询

HTML:
<body id="-1">
<p id="3.14">click here to set variable to 3.14</p>
<h3 id="5">click here to set variable to 5</h3>
<p id ="2">click here to set variable to 2</p>
<p id ="2310">click here to set variable to 2310</p>
<div id="load"></div>
JS:
document.body.onmousedown = whichElement;
var output = document.getElementById("load")
function whichElement(e) {
e = e || window.event;
var targ = e.target || e.srcElement;
if (targ.nodeType===3) {// defeat Safari bug
targ = targ.parentNode;
}
output.innerHTML = targ.innerHTML;
}

注意:如果我记得很清楚,在HTML5中id
可以是您想要的,但在HTML5之前它应该以字母开头,而不是数字。
