Contenteditable文本编辑器和光标位置

问题描述

 < p>< p>如何使用jquery或其他插入HTML在我的contenteditable div的光标/ ; div contenteditable =true> Hello world< / div> 
  

例如，如果光标/插入符号介于hello和world之间，然后用户点击一个按钮，例如插入图片，然后使用javascript，像< img src = etc etc> 之类的东西插入到hello和world之间。我希望我已经明确了这一点= S $ / B
$ b

示例代码将非常感谢，非常感谢！

解决方案

以下函数将在所有主流桌面浏览器的光标位置插入一个DOM节点（元素或文本节点）：

 函数insertNodeAtCursor（node）{
 var sel，range，html; 
 if（window.getSelection）{
 sel = window.getSelection（）; 
 if（sel.getRangeAt&& sel.rangeCount）{
 sel.getRangeAt（0）.insertNode（node）; 
} 
} else if（document.selection&& document.selection.createRange）{
 range = document.selection.createRange（）; 
 html =（node.nodeType == 3）？ node.data：node.outerHTML; 
 range.pasteHTML（html）; 
 
 
 
 
 $ b如果你宁愿插入一个HTML字符串： p> 
 
 
  function insertHtmlAtCursor（html）{
 var sel，range，node; 
 if（window.getSelection）{
 sel = window.getSelection（）; 
 if（sel.getRangeAt&& sel.rangeCount）{
 range = window.getSelection（）。getRangeAt（0）; 
 node = range.createContextualFragment（html）; 
 range.insertNode（node）; 
} 
} else if（document.selection&& document.selection.createRange）{
 document.selection.createRange（）。pasteHTML（html）; 
} 
} 
  
我已将此从我的答案改编为类似问题： 
 
How can I (using jquery or other) insert html at the cursor/caret position of my contenteditable div:
<div contenteditable="true">Hello world</div>
For example, if the cursor/caret was between "hello" and "world" and the user then clicked a button, eg "insert image", then using javascript, something like <img src=etc etc> would be inserted between "hello" and "world". I hope I've made this clear =S
Example code would be greatly appreciated, thanks a lot!
 解决方案 
The following function will insert a DOM node (element or text node) at the cursor position in all the mainstream desktop browsers:
function insertNodeAtCursor(node) {
    var sel, range, html;
    if (window.getSelection) {
        sel = window.getSelection();
        if (sel.getRangeAt && sel.rangeCount) {
            sel.getRangeAt(0).insertNode(node);
        }
    } else if (document.selection && document.selection.createRange) {
        range = document.selection.createRange();
        html = (node.nodeType == 3) ? node.data : node.outerHTML;
        range.pasteHTML(html);
    }
}
If you would rather insert an HTML string:
function insertHtmlAtCursor(html) {
    var sel, range, node;
    if (window.getSelection) {
        sel = window.getSelection();
        if (sel.getRangeAt && sel.rangeCount) {
            range = window.getSelection().getRangeAt(0);
            node = range.createContextualFragment(html);
            range.insertNode(node);
        }
    } else if (document.selection && document.selection.createRange) {
        document.selection.createRange().pasteHTML(html);
    }
}
I've adapted this from my answer to a similar question: How to find cursor position in a contenteditable DIV?
