项目中经常遇到获取上个页面跳转过来获取当前的参数
//获取地址栏参数，name:参数名称
function getUrlParms(name){
var reg = new RegExp("(^|&)"+ name +"=([^&]*)(&|$)");
var r = window.location.search.substr(1).match(reg);
if(r!=null)
return unescape(r[2]);
return null;
}
var id = getUrlParms("id");
上述方法可以获取地址栏传过来的id，还可以这样写
function getRequest() {
var url = window.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]]=decodeURI(strs[i].split("=")[1]);
}
}
return theRequest;
}
var id= getRequest().id;
