问题描述
我有一个具有行号和文本的contentEditable iframe.行号包含在div中，所有文本均包含在<pre>元素中.
I have a contentEditable iframe with line numbers and text. The line numbers are contained in a div and all text is in a <pre>-element.
它看起来像这样:
<body>
<div id="line_numbers">
<div>1</div><div>2</div><div>3</div>
</div>
<pre>
Text
</pre>
</body>
现在，当有人按Ctrl + A时，将选择所有内容，包括行号.我想将此行为更改为仅包含<pre>的内容.
Now, when someone presses Ctrl+A everything is selected, including the line numbers. I would like to change this behaviour to only include the contents of the <pre>.
我已经设置了一个捕获Ctrl + A并阻止默认操作的函数.现在，如何设置选择以包含<pre>中的所有内容?
I have set up a function that captures Ctrl+A and prevents the default operation. Now, how do I set the selection to contain everything within the <pre>?
推荐答案
我认为会对您有所帮助；您应该能够使用jQuery选择pre元素并将其传递到提供的函数中:
This answer will help you out I think; you should be able to select the pre element using jQuery and pass it into the function supplied:
SelectText($('pre')[0]);
