用法 var id = getParam("id");

function getParam(strKey)
            {
                var url=document.URL;
                //var url="file://wqasdasd/www/1.html?id=2&index=5";
                var para="";
                if(url.lastIndexOf(strKey)<0)
                {

                }
                else
                {
                    if(url.lastIndexOf("?")>0)
                    {
                        url = url.substring(url.lastIndexOf("?")+1,url.length);
                        var arr=url.split("&");
                        for(var i=0;i<arr.length;i++)
                        {
                            if(arr[i].split("=")[0] == strKey )
                            {
                                return arr[i].split("=")[1];
                            }
                        }
                    }
                }
                return para;
            }
