本文主要和大家介绍了JS正则表达式替换url的参数的方法及js使用正则表达式从url中获取参数值的代码,需要的朋友可以参考下,希望能帮助到大家。

具体代码如下所示:


/* 定义替换对象键值 */
var setReferArgs = function(){
 var referArgs = new Object();
 referArgs['#userID\#'] = userId;
 referArgs['\#userName\#'] = userName;
 return referArgs;
}
/* 替换URL的参数 */
var replaceUrlParams = function(url){
 var actualUrl = "";
 var referArgs = setReferArgs();
 for(var key in referArgs){
 var e = eval('/'+ key +'/g'); 
 actualUrl = url.replace(e,referArgs[key]);
 url = actualUrl;
 }
 return actualUrl;
}

栗子:

 “http://10.0.0.250:8088/test?uesrID=#userID#” 替换成对应数值 “http://10.0.0.250:8088/test?uesrID=12345”;

 “http://10.0.0.250:8088/test/#userID#” 替换成对应数值 “http://10.0.0.250:8088/12345”;
