js操作浏览器的参数方法

实例如下：

function getQueStr(url, ref) //取获参数值
{
 var str = url.substr(url.indexOf('?') + 1);
 if (str.indexOf('&') != -1) {
 var arr = str.split('&');
 for (i in arr) {
 if (arr[i].split('=')[0] == ref)
 return arr[i].split('=')[1];
 }
 }
 else {
 return url.substr(url.indexOf('=') + 1)
 }
}

function setQueStr(url, ref, value) //设置参数值
{
 var str = "";
 if (url.indexOf('?') != -1)
 str = url.substr(url.indexOf('?') + 1);
 else
 return url + "?" + ref + "=" + value;
 var returnurl = "";
 var setparam = "";
 var arr;
 var modify = "0";

 if (str.indexOf('&') != -1) {
 arr = str.split('&');

 for (i in arr) {
 if (arr[i].split('=')[0] == ref) {
 setparam = value;
 modify = "1";
 }
 else {
 setparam = arr[i].split('=')[1];
 }
 returnurl = returnurl + arr[i].split('=')[0] + "=" + setparam + "&";
 }

 returnurl = returnurl.substr(0, returnurl.length - 1);

 if (modify == "0")
 if (returnurl == str)
 returnurl = returnurl + "&" + ref + "=" + value;
 }
 else {
 if (str.indexOf('=') != -1) {
 arr = str.split('=');

 if (arr[0] == ref) {
 setparam = value;
 modify = "1";
 }
 else {
 setparam = arr[1];
 }
 returnurl = arr[0] + "=" + setparam;
 if (modify == "0")
 if (returnurl == str)
 returnurl = returnurl + "&" + ref + "=" + value;
 }
 else
 returnurl = ref + "=" + value;
 }
 return url.substr(0, url.indexOf('?')) + "?" + returnurl;
}

function delQueStr(url, ref) //删除参数值
{
 var str = "";

 if (url.indexOf('?') != -1)
 str = url.substr(url.indexOf('?') + 1);
 else
 return url;
 var arr = "";
 var returnurl = "";
 var setparam = "";
 if (str.indexOf('&') != -1) {
 arr = str.split('&');
 for (i in arr) {
 if (arr[i].split('=')[0] != ref) {
 returnurl = returnurl + arr[i].split('=')[0] + "=" + arr[i].split('=')[1] + "&";
 }
 }
 return url.substr(0, url.indexOf('?')) + "?" + returnurl.substr(0, returnurl.length - 1);
 }
 else {
 arr = str.split('=');
 if (arr[0] == ref)
 return url.substr(0, url.indexOf('?'));
 else
 return url;
 }
}
