referraluserid推广ID号跟踪JS处理A标签

网站推广ID号跟踪

xxx.html?referraluserid=123

referraluserid.js 　　JS源文件

referraluserid的参数会自动绑定页面A标签

有时是Post 表单跳转时不传数会丢失，这时可以根据后台或其它方式重新打印到前台页面，让Js重新获取到

<script type="text/javascript">

　　var referraluserid = '<%=BackReferraluserid%>';// BackReferraluserid 为后台值绑定到Js变量

</script>

紧接着引用JS文件

<script type="text/javascript" src="/Scripts/referraluserid.js"></script>

document.write("<input type='hidden' id='referraluserid' name='referraluserid' />");

$(document).ready(function () {
$("a").each(function () {
if ($(this).attr("href") == "#" || $(this).attr("href") == "") {
$(this).attr("href", "/");
}
});
addUrlParse("referraluserid");
});
function getUrlParams() {
var search = window.location.search;
var tmparray = search.substr(1, search.length).split("&");
var paramsArray = new Array;
if (tmparray != null) {
for (var i = 0; i < tmparray.length; i++) {
var reg = /[=|^==]/;
var set1 = tmparray[i].replace(reg, '&');
var tmpStr2 = set1.split('&');
var array = new Array;
array[tmpStr2[0]] = tmpStr2[1];
paramsArray.push(array);
}
}
return paramsArray;
}

function GetQueryString(name) {
var paramsArray = getUrlParams();
if (paramsArray != null) {
for (var i = 0; i < paramsArray.length; i++) {
for (var j in paramsArray[i]) {

if (j.toLowerCase() == name.toLowerCase()) {
return paramsArray[i][j];
}
}
}
}
return null;
}

// typeof addUrlParse == "function" ?  addUrlParse("referraluserid") : "";
function addUrlParse(ruid) {

var ruidValue = GetQueryString(ruid);
