静态页面值传递之URL篇

URL篇
能过URL进行传值.把要传递的信息接在URL上.

Post.htm

<input type="text" name="username">
<input type="text" name="sex">
<input type="button" value="Post">
<script language="javascript" >
function Post()
{
     //单个值 Read.htm?username=baobao;
     //多全值 Read.htm?username=baobao&sex=male;
     url = "Read.htm?username="+escape(document.all.username.value);
     url += "&sex=" + escape(document.all.sex.value);
     location.href=url;
}
</script>


Read.htm

<script language="javascript" >
/*
*--------------- Read.htm -----------------
* Request[key]
* 功能:实现ASP的取得URL字符串,Request("AAA")
* 参数:key,字符串.
* 实例:alert(Request["AAA"])
*--------------- Request.htm -----------------
*/
var url=location.search;
var Request = new Object();
if(url.indexOf("?")!=-1)
{
     var str = url.substr(1)   //去掉?号
     strs = str.split("&");
     for(var i=0;i<strs.length;i++)
     {
         Request[strs[i ].split("=")[0]]=unescape(strs[ i].split("=")[1]);
     }
}
alert(Request["username"])
alert(Request["sex"])
</script>



<script language="JavaScript">
<!--
function Request(strName)
{
var strHref = "www.abc.com/index.htm?a=1&b=1&c=测试测试";
var intPos = strHref.indexOf("?");
var strRight = strHref.substr(intPos + 1);

var arrTmp = strRight.split("&");
for(var i = 0; i < arrTmp.length; i++)
{
var arrTemp = arrTmp[i ].split("=");

if(arrTemp[0].toUpperCase() == strName.toUpperCase()) return arrTemp[1];
}
return "";
}

alert(Request("a"));
alert(Request("b"));
alert(Request("c"));
//-->
</script>

<script>
String.prototype.getQuery = function(name)
{
  var reg = new RegExp("(^|&)"+ name +"=([^&]*)(&|$)");
  var r = this.substr(this.indexOf("\?")+1).match(reg);
  if (r!=null) return unescape(r[2]); return null;
}
var str ="www.abc.com/index.htm?a=1&b=1&c=测试测试";
alert(str.getQuery("a"));
alert(str.getQuery("b"));
alert(str.getQuery("c"));
</script>


优点:取值方便.可以跨域.
缺点:值长度有限制.
