從A頁面通過url傳參到B頁面時，解析url參數可以用下面兩種方法：
方法一：正則分析法
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;
}
這樣調用：
alert(GetQueryString("參數名1"));
alert(GetQueryString("參數名2"));
alert(GetQueryString("參數名3"));
方法二：
<span
style="font-size:
16px;"><Script
language="javascript">
function GetRequest()
{
var url
= location.search; //獲取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>
|
這樣調用：
<Script language="javascript">
var Request = new Object();
Request = GetRequest();
var 參數1,參數2,參數3,參數N;
參數1 = Request['參數1'];
參數2 = Request['參數2'];
參數3 = Request['參數3'];
參數N = Request['參數N'];
</Script>
如果參數中含有中文字符，注意轉編碼和解碼：
- <span style="font-size:18px;">1.傳參頁面
- Javascript代碼：<script type=”text/javascript”>
- function send(){
- var url = "test01.html";
- var userName = $("#userName").html();
- window.open(encodeURI(url + "?userName=" + userName)); }
- </script>
- 2. 接收參數頁面：test02.html
- <script>
- var urlinfo = window.location.href;//獲取url
- var userName = urlinfo.split(“?”)[1].split(“=”)[1];//拆分url得到”=”后面的參數
- $(“#userName”).html(decodeURI(userName));
- </script></span>
