如何获取页面引荐来源网址并使用jquery .load将内容加载到div中

Question

我在WordPress博客上有一个下载页面。在此页面上，我想从链接到下载页面的任何URL中获取带有id =“ download”的HTML元素。

请问我如何做到这一点？看看下面我的代码，但是它不起作用

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.1/jquery.min.js"> </script>

<script type="text/javascript">
var pagereferrer = Document.referrer;
var timeleft = 10;
var downloadTimer = setInterval(function(){
timeleft--;
document.getElementById("countdowntimer").textContent = timeleft;
if(timeleft <= 0)
clearInterval(downloadTimer);
},1000);

$( "#div1" ).load(pagereferrer #download);
</script>

<h2>
<span style="font-family: 'comic sans ms', sans-serif;">
<strong>Please wait ! Your download will begin in <span id="countdowntimer">10 </span> Seconds.......</strong>
</span>
</h2>

<div id="div1"> </div>

Answer 1

这将帮助您

<script type="text/javascript">
var pagereferrer = Document.referrer;
var timeleft = 10;
var downloadTimer = setInterval(function(){
timeleft--;
document.getElementById("countdowntimer").innerHTML = timeleft;
if(timeleft <= 0)
clearInterval(downloadTimer);
},1000);


jQuery( "#div1" ).load( "pagereferrer #download" );
// or
// jQuery( "#div1" ).load( "ajax/test.html #container" );

</script>
