好久没来blueidea了，过来看看发个东西做个纪念. . . 顺便看看对大家有没有用~

var rex=/(http:\/\/)?\S+\.[mp4|flv|f4v]{3}/ig;

可以复制以下代码存为 html直接测试。

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>正则式提取视频地圵测试</title>
    <script>
       window.onload =function () {
            var oTxt=document.getElementById('txt1');
            var oTxt2=document.getElementById('txt2');
            var btn=document.getElementById('btn1');
            btn.onclick=function () {
               var rex=/(http:\/\/)?\S+\.[mp4|flv|f4v]{3}/ig;
               var str=oTxt.value.match(rex);
                var re=/,/g;
                oTxt2.value=String(str).replace(re,'\n');
            };
       };
    </script>
</head>
<body>
<textarea id="txt1" cols="80" rows="15">
     The error says that the layer index you're trying to assign is not between 1 and 31, which is why you're getting the error and it says what it does.Edit: The problem is that you're trying to assign a layer mask to a layer. video: Http://www.mythlong.com/demo/video/mAin.mp4; sound: You need to store ints instead of LayerMasks.A layer identifier on a gameobject is an int with a value between 1 and 31. A layer mask is a bitwise mask for one or https:///mythlodasfng.net/viddsdeo/mbbbn4850_345DASFSYNFGSDOIY498023475_.f4v more layers. When you set the object's layer to the layer mask, it implicitly converts it to a mask. So, Video:www.mythlong.com/dedmo/vide2o/mai2.flvwhen you choose layer 8, the mask is set to binary 00000000000000000000000010000000, which evaluates to decimal 256, far outside the allowed range.To fix the problem, use simple ints instead of layer masks.

提示：您可以先修改部分代码再运行
