浅析JS获取url中的参数实例代码

function UrlSearch() {var name, value;var str = location.href; //取得整个地址栏var num = str.indexOf("?")str = str.substr(num + 1); //取得所有参数 stringvar.substr(start [, length ]var arr = str.split("&"); //各个参数放到数组里for (var i = 0; i < arr.length; i++) {num = arr[i].indexOf("=");if (num > 0) {name = arr[i].substring(0, num);value = arr[i].substr(num + 1);this[name] = value;}}} 

//跳转页面的链接url: contextPath+"/page4nui/ci2k3/prreportcheckmngt/report_check.jsp?ciPrId="+ciPrId//跳转到的页面使用var url = new UrlSearch();ciPrId = url.ciPrId;
