有没有办法将这3个函数简化为1个函数？
<html>
<head>
<meta content="text/html; charset=utf-8" http-equiv="Content-Type">
<title>Vote!</title>
<script type="text/javascript">
var x1 = 0;
function countClicks() {
x1 += 1
document.getElementById( "counting" ).innerHTML = x1;
ClickCount++;
return true;
}
</script>
<script type="text/javascript">
var x2 = 0;
function countClicks1() {
x2 += 1
document.getElementById( "counting1" ).innerHTML = x2;
ClickCount++;
return true;
}
</script>
<script type="text/javascript">
var x3 = 0;
function countClicks2() {
x3 += 1
document.getElementById( "counting2" ).innerHTML = x3;
ClickCount++;
return true;
}
</script>

当然 。将您的 div id 作为参数传递给函数。请参阅 http://jsfiddle.net/KsePr/ 进行演示。
需要注意的是，如果您尝试在网页上实现某种投票系统，则需要在服务器端而不是客户端进行投票增量。
Of course . Pass your div id as an argument to the function . See http://jsfiddle.net/KsePr/ for a demo .
One word of caution - If you are trying to implement some kind of voting system on a webpage , you'll need to do the vote incrementing in at the server side , not the client side .
试试这个：
现在您可以使用任何您想要的元素 id 来调用它，例如：
请注意，这适用于任意数量的元素。
Try this:
Now you can call it with any element id you want, like:
Note that this will work with any number of elements.
