Cal*_*l S 6 html javascript jquery contenteditable
我怎么能(使用jquery或其他)在我的contenteditable div的光标/插入位置插入html:
<div contenteditable="true">Hello world</div>

例如,如果光标/插入符号位于"hello"和"world"之间,则用户然后单击按钮,例如"插入图像",然后使用javascript,类似于<img src=etc etc>将插入"hello"和"world"之间.我希望我已经明确表示= S.
非常感谢示例代码,非常感谢!

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

如果您想要插入HTML字符串:
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);
}
}

我从我对类似问题的回答中对此进行了调整:如何在一个可疑的DIV中找到光标位置?

我建议使用 jquery 插件a-tools
\n\n该插件有七大功能:
\n\n* getSelection \xe2\x80\x93 return start, end position, length of the selected text and the selected text. return start=end=caret position if text is not selected;\n* replaceSelection \xe2\x80\x93 replace selected text with a given string;\n* setSelection \xe2\x80\x93 select text in a given range (startPosition and endPosition);\n* countCharacters \xe2\x80\x93 count amount of all characters;\n* insertAtCaretPos \xe2\x80\x93 insert text at current caret position;\n* setCaretPos \xe2\x80\x93 set cursor at caret position (1 = beginning, -1 = end);\n* setMaxLength \xe2\x80\x93 set maximum length of input field. Also provides callback function if limit is reached. Note: The function has to have a number as input. Positive value for setting of limit and negative number for removing of limit.\nRun Code Online (Sandbox Code Playgroud)\n\n您需要的是insertAtCaretPos:
\n\n$("#textarea").insertAtCaretPos("<img src=etc etc>");\nRun Code Online (Sandbox Code Playgroud)\n\n可能有一个缺点:此插件仅适用于 textarea en input:text 元素,因此可能与 contenteditable 发生冲突。
