使用javascript在单个左键单击中选择div中的所有文本 [英] selecting all text within a div on a single left click with javascript

问题描述

我在div中有一个简单的不可点击的链接，如下所示：

I have a simple non-clickable link within a div that looks like this:

这是一个可共享的链接，用户可以将粘贴复制到其他内容。

It's meant to be a sharable link that the user can copy paste into other things.

可用性目的，我想在div中的任意位置单击左键选择整个链接：

For usability purposes, I want a single left click anywhere within the div to select the entire link:

我对javascript / web编程了解不多，所以我尝试了以下内容：

I don't know much about, javascript/web programming, so I've tried the following:

<div id="share_link" onClick="select_all('share_link')"><%= request.url %></div>

此javascript

and this javascript

<script type="text/javascript">
    function select_all(id) {
        document.getElementById(id).focus();
    }
</script>

这不起作用。我想知道为了实现我想要的东西，我应该做的最简单的事情是什么。我考虑过将div更改为文本输入或将文本更改为链接，但理想情况下，内容应该是只读的，不可编辑的，不可点击的

This doesn't work. I'd like to know what's the simplest thing I should do to achieve what I want. I thought about changing the div to a text input or the text within to be a link, but ideally the content within should be read-only, non-editable, and non-clickable

推荐答案

与其他浏览器相比，这在IE中完全不同。以下内容适用于所有主流浏览器：

This is achieved completely differently in IE compared to other browsers. The following will work in all major browsers:

<script type="text/javascript">
    function select_all(el) {
        if (typeof window.getSelection != "undefined" && typeof document.createRange != "undefined") {
            var range = document.createRange();
            range.selectNodeContents(el);
            var sel = window.getSelection();
            sel.removeAllRanges();
            sel.addRange(range);
        } else if (typeof document.selection != "undefined" && typeof document.body.createTextRange != "undefined") {
            var textRange = document.body.createTextRange();
            textRange.moveToElementText(el);
            textRange.select();
        }
    }
</script>

<div onclick="select_all(this)">Link text</div>
