如果实现复制一个链接或者文本，其实很简单的，但是有很多个要复制呢，这里我们需要用到for循环相关的技术知识，比如我们需要操作一下列表内容的复制，如下图：
然后分享下源码：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>多个复制</title>
</head>
<body>
<input type="text" id = "url1" value = "http://www.baidu.com"><a href="javascript:(0)" id = "btn1">点我复制</a><br />
<input type="text" id = "url2" value = "http://www.jd.com"><a href="javascript:(0)" id = "btn2">点我复制</a><br />
<input type="text" id = "url3" value = "http://www.hshs.com"><a href="javascript:(0)" id = "btn3">点我复制</a><br />
<input type="text" id = "url4" value = "http://www.iii.com"><a href="javascript:(0)" id = "btn4">点我复制</a>
<script src = "/demo/js/jq.js"></script>
<script type="text/javascript">
var btn = [];
var url = []
var len = $("input").size();
for (var i = 0; i < len; i++) {
btn.push("#btn" + (i + 1));
url.push("#url" + (i + 1));
}
console.log(btn);
for(var j in btn){
(function(data_j){
$(btn[data_j]).bind("click", function () {
$(url[data_j]).select();
document.execCommand("Copy");
});
})(j);
}
</script>
</body>OK，供大家学下咯
