onclick jumps to page processing without refreshing

<span>同求，一个事件onclick不刷新就跳转到页面处理。类似 于点赞，
asp文件，自己写了一个，不转
function zan(){
xmlHttp.open("post", "zan.asp?id=122", true);
}</span>

<span></span>

<span></span>

function deletea(){
<span></span>createXMLHttpRequest();
<span></span> var id=123123; 
<span></span> var url='<{:U("Project/test?name=1236")}>';
<span></span>  xmlHttp.open("GET",url,true);
<span></span>  xmlHttp.send(null);
<span></span> 
}

The above introduces the processing of onclick jumping to the page without refreshing, including the relevant content. I hope it will be helpful to friends who are interested in PHP tutorials.
