How to print one specific Javascript variable in HTML?
提问by user2979725
I want to ask how I can print a Javascript variable in HTML form (e.g. output it on the screen)?
我想问一下如何以 HTML 形式打印 Javascript 变量（例如将其输出到屏幕上）？
Here is my JS code:
这是我的 JS 代码：
<script type="text/javascript">
var howLongIsThis = myPlayer.duration();
</script>
This var howLongIsThis = myPlayer.duration();is Jquery variable!
这var howLongIsThis = myPlayer.duration();是 Jquery 变量！
So how i can show this value in HTML page?
那么我如何在 HTML 页面中显示这个值呢？

Set it to be the innerHTML or value of a html element:
将它设置为一个 html 元素的 innerHTML 或值：
var howLongIsThis = myPlayer.duration();
var displayEl = document.getElementById("duration");
displayEl.innerHTML = howLongIsThis;
or if you want in in a form field:
或者如果你想在表单字段中：
displayEl.value = howLongIsThis;

Assuming you have a <div id="example"></div>somewhere in your HTML, you want to run JavaScript after the DOM has loaded which adds the value you want to that div. In jQuery (which you specified in your question you're using), this would simply be:
假设您<div id="example"></div>在 HTML 中的某个地方有一个，您希望在 DOM 加载后运行 JavaScript，将您想要的值添加到div. 在 jQuery（您在您使用的问题中指定）中，这将是：
$('div#example').html(myPlayer.duration());
