从A页面通过url传参到B页面时,解析url参数可以用下面两种方法:
方法一:正则分析法
function getQueryString(name) {
var reg = new RegExp("(^|&)" + name + "=([^&]*)(&|$)", "i");
var r = window.location.search.substr(1).match(reg);
if (r != null) return unescape(r[2]); return null;
}
这样调用:
alert(GetQueryString("参数名1"));
alert(GetQueryString("参数名2"));
alert(GetQueryString("参数名3"));
方法二:
<span style="font-size: 16px;"><Script language="javascript">
function GetRequest() {
var url = location.search; //获取url中"?"符后的字串
var theRequest = new Object();
if (url.indexOf("?") != -1) {
var str = url.substr(1);
strs = str.split("&");
for(var i = 0; i < strs.length; i ++) {
theRequest[strs[i].split("=")[0]]=unescape(strs[i].split("=")[1]);
}
}
return theRequest;
}
</Script></span>
这样调用:
<Script language="javascript">
var Request = new Object();
Request = GetRequest();
var 参数1,参数2,参数3,参数N;
参数1 = Request['参数1'];
参数2 = Request['参数2'];
参数3 = Request['参数3'];
参数N = Request['参数N'];
</Script>
如果参数中含有中文字符,注意转编码和解码:
<span style="font-size:18px;">1.传参页面
Javascript代码:<script type=”text/javascript”>
function send(){
var url = "test01.html";
var userName = $("#userName").html();
window.open(encodeURI(url + "?userName=" + userName)); }
</script>
2. 接收参数页面:test02.html
<script>
var urlinfo = window.location.href;//获取url
var userName = urlinfo.split(“?”)[1].split(“=”)[1];//拆分url得到”=”后面的参数
$(“#userName”).html(decodeURI(userName));
</script></span>
