使用 Javascript 获取页面的 url 并在链接中使用它 [英] Use Javascript to get url of the page and use it in a link

问题描述

我已经寻找并寻找了这个问题的答案.所以当解决方案很简单时，我提前道歉.

I have looked and looked for an answer to this question. So I apologize in advance when the solution is very easy.

我想获取当前页面的网址，例如.www.example.com/example.html 并使用 javascript 将其放入链接(以及其他用途)中.

I want to take the url of the current page eg. www.example.com/example.html and put this in a link (among other uses) using javascript.

所以它看起来像这样:

<a href"www.example.com/example.html"></a>

我已经尝试了很多我知道我需要使用 location.href 但似乎无法让它工作的东西.

I've tried lots of things I know I need to use location.href but just can't seem to get it to work.

这是我最接近让它工作的方法:

This is the closest I got to getting it to work,:

<a href"javascript:write.location.href;"></a>

谢谢，再次抱歉.我是 JS 和 html 的新手.

Thanks, sorry again. I'm new to JS and html.

推荐答案

使用 ID 命名您的元素，例如:<a id="pageLink"></a> 然后当文档加载时，您可以运行此代码段:

Name your element with an ID, like: <a id="pageLink"></a> and then when the document loads you can run this snippet:

var link = document.getElementById("pageLink");
link.setAttribute("href", window.location.href);

或者，使用 jQuery 之类的东西:

Or, with something like jQuery:

$("#pageLink").attr("href", window.location.href);

编辑在评论中回答您的问题:

EDIT In response to your question in the comments:

我不确定我是否完全理解你，但如果它是固定的，那么你只需在设置之前连接到 href，例如

I'm not sure I'm understanding you completely but if it's fixed, then you'd simply concatenate to the href before setting it, e.g.

$("#pageLink").attr("href", staticUrl + window.location.href);
