我们知道，在服务器端asp，jsp等程序可以接受html页面上的form传来的参数。那么，可不可以传递参数给html页面呢。可以。
原理：通过window.location.href中的分割符获得各个参数
方法一：
/*
*函数功能：从href获得参数
*sHref: http://www.cscenter.com.cn/arg.htm?arg1=d&arg2=re
*sArgName:arg1, arg2
*return: the value of arg. d, re
*/
function GetArgsFromHref(sHref, sArgName)
{
var args = sHref.split("?");
var retval = "";
if(args[0] == sHref) /*参数为空*/
{
return retval; /*无需做任何处理*/
}
var str = args[1];
args = str.split("&");
for(var i = 0; i < args.length; i ++)
{
str = args[i];
var arg = str.split("=");
if(arg.length <= 1) continue;
if(arg[0] == sArgName) retval = arg[1];
}
return retval;
}
function getvalue(name)
{
var str=window.location.search;
if (str.indexOf(name)!=-1)
{
var pos_start=str.indexOf(name)+name.length+1;
var pos_end=str.indexOf("&",pos_start);
if (pos_end==-1)
{
return str.substring(pos_start);
}
else
{
return str.substring(pos_start,pos_end)
}
}
else
{
return "没有这个name值";
}
}
alert(getvalue(name));
方法三：{
var str=window.location.search;
if (str.indexOf(name)!=-1)
{
var pos_start=str.indexOf(name)+name.length+1;
var pos_end=str.indexOf("&",pos_start);
if (pos_end==-1)
{
return str.substring(pos_start);
}
else
{
return str.substring(pos_start,pos_end)
}
}
else
{
return "没有这个name值";
}
}
alert(getvalue(name));
Request = {
QueryString : function(item){
var svalue = location.search.match(new RegExp("[\?\&]" + item + "=([^\&]*)(\&?)","i"));
return svalue ? svalue[1] : svalue;
}
}
alert(Request.QueryString("id"));
方法四:QueryString : function(item){
var svalue = location.search.match(new RegExp("[\?\&]" + item + "=([^\&]*)(\&?)","i"));
return svalue ? svalue[1] : svalue;
}
}
alert(Request.QueryString("id"));
var url=location.search;
var Request = new Object();
if(url.indexOf("?")!=-1)
{
var str = url.substr(1); //去掉?号
strs = str.toLowerCase();
strs = strs.split("&");
for(var i=0;i<strs.length;i++)
{
Request[strs[i].split("=")[0]]=unescape(strs[i].split("=")[1]);
}
}
var mapWidth = Request["w"];
var mapHeight = Request["h"];
var Request = new Object();
if(url.indexOf("?")!=-1)
{
var str = url.substr(1); //去掉?号
strs = str.toLowerCase();
strs = strs.split("&");
for(var i=0;i<strs.length;i++)
{
Request[strs[i].split("=")[0]]=unescape(strs[i].split("=")[1]);
}
}
var mapWidth = Request["w"];
var mapHeight = Request["h"];
