怎么用javascript取当前页面的参数??

[dazhong23]

比如当前页面是 aaaa.aspx?id={0}&name={1}

我想用脚本
window.onload=function(){
//这里怎么写??请大家帮忙

}

用截取字符串
indexOf,substring函数等可以实现．

[cpp2017]

var str = "http://localhost/aaa.aspx?aa=1&bb=2&cc=3&dd=4afasfsf"; alert(GetQueryString(str,"aa")); alert(GetQueryString(str,"bb")) alert(GetQueryString(str,"cc")) alert(GetQueryString(str,"dd")) function GetQueryString(url,key) { var reg = new RegExp(".*?"+ key+"=([^&]*)?&.*?$"+"|.*?"+key+"=([^&]*)?$|"); if(reg.exec(url) == url) return ""; return url.replace(reg,"$1$2"); // return reg.exec(url)[0].Value; } //--> </SCRIPT>

<script language=”JavaScript”>
var urlParts = document.URL.split(“?”);
var parameterParts = urlParts[1].split(“&”);
for (i = 0; i < parameterParts.length; i++) {
var pairParts = parameterParts[i].split(“=”);
var pairName = pairParts[0];
var pairValue = pairParts[1];
document.write(pairName + “ ：“ +pairValue );
}
</script>

var a = window.location.search //获得?id={0}&name={1}
var b = a.split('&'); //按&分组
var id =b[0].split('=')[1];
var name = b[1].split('=')[1];

的方法好；收藏了~~

[babyrockxray]

function getArgs()
{
var args = new Object();
var query = location.search.substring(1);
var pairs = query.split('&');
for(var i=0; i<pairs.length; i++)
{
var pos = pairs[i].indexOf('=');
if(pos == -1)
continue;
var argname = pairs[i].substring(0,pos);
var value = pairs[i].substring(pos+1);
args[argname] = decodeURIComponent(value);
}
return args;
}

window.onload = function()
{
var args = getArgs();
alert(args["id"]);
}
