一段字符中匹配出网址，可以将css里复制的url(blabla)匹配网址方便下图
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>match</title>
<script type="text/javascript">
window.onload = function() {
var str = "url(http://img2.cache.netease.com/f2e/wap/touch_index_2016/trunk/images/download_2017.png) no-repeat";
var reg = /http:\/\/\w*(\.\w*)+/ig;
var arr = str.match(reg);
console.log(arr);
btn.onclick = function() {
var text = document.getElementById(‘text‘);
var input = document.createElement(‘input‘);
var str1=text.value;
var arr1=str1.match(reg);
console.log(arr1);
input.value = arr1;
btn.appendChild(input);
}
}
</script>
<input type="text" name="text" id="text" placeholder="粘贴至此" value="" />
<button id="btn">链接</button>
