Question

你们如何在文本中找到目前选定的案文(并修改案文)?

我看到了可以听取意见的选定活动,但我很想知道,是否找到了目前选定的案文。

另外,为了能够修改案文中这一具体部分,你需要使用哪些技术? 我以某种方式认为,选择的立场属于整个案文的内容?

我希望能够做的是选择和修改,或者把选择归结到某些标签上,就像你能够做的那样。

Answer 1

我把我认为在所有浏览器(包括E < 9)中这样做的明确职能多次张贴在Stack Overflow上。例如:

https://stackoverflow.com/questions/3622818/ies-document-selection-createrange-doesnt-include-leading-or-trailing-blank-lin/3648244#3648244>IE s document.selection.createRange don t include leading or踪迹ing blank Line

I d also recommend my jQuery plug-in for this, which includes this function and others to insert, delete, surround or replace the selected text, which sounds like exactly what you want. It s also the only jQuery plug-in for textarea selections I m aware of that works correctly with line breaks in IE < 9.

Answer 2

如果你只得支持最新的浏览器,你可以使用<条码>选择标准<>和<条码>选择/代码>,从而暴露了文本领域所选案文的性质立场。你可以只修改选定的案文,但更新了你可以使用的<条码>>选择Range,以重选案文。
