You don't even need jQuery; vanilla JS will work fine...
你甚至不需要 jQuery；vanilla JS 可以正常工作...
<a id="link" href="http://example.com">Go NOW!!!</a>

JS：
window.setTimeout(function() {
location.href = document.getElementsByClassName("user_register border_y")[0].getElementsByTagName("a")[0].href;
}, 2000);
getElementsByClassNamedoesn't work in all browsers; so make sure you provide a fallback
getElementsByClassName不适用于所有浏览器；所以确保你提供了一个后备

Use JavaScript to redirect. For example:
使用 JavaScript 进行重定向。例如：
<script type="text/javascript">
var time = 15; // Time coutdown
var page = "http://www.redirect-url.com/";
function countDown(){
time--;
gett("timecount").innerHTML = time;
if(time == -1){
window.location = page;
}
}
function gett(id){
if(document.getElementById) return document.getElementById(id);
if(document.all) return document.all.id;
if(document.layers) return document.layers.id;
if(window.opera) return window.opera.id;
}
function init(){
if(gett('timecount')){
setInterval(countDown, 1000);
gett("timecount").innerHTML = time;
}
else{
setTimeout(init, 50);
}
}
document.onload = init();
</SCRIPT>
add this code after body tab
在正文选项卡后添加此代码
<h3>Auto redirect after <span id="timecount"></span> second(s)!</h3>
