我正在尝试为TinyMCE创建一个插件，因此用户可以为选定区域添加浮动提示。 我需要的是将选定的内容放入span中，我这样做：
var formated =
'<span id="tooltip_widget_' + id + '">'
+ selectedtext
+ '</span>;
ed.selection.setContent(formated);
它在Firefox中运行良好，我可以添加文本以跨越并继续输入。 但是在Chrome和IE中，以下所有文字都会进入增加的范围。并且继续输入它的唯一方法 - 通过html编辑器。
我尝试在插入后包含额外的插入符占位符范围，然后在它之后折叠，然后删除此占位符以确保插入符号位于插入的范围之后。
但它没有帮助。在chrome和IE中，如果插入符号位于span的末尾，它将继续在此范围内键入。
请建议如何解决这个问题。

/**
*
* Here goes dialog.js
* What exactly my plugin does
*
* ================== GOAL =====================
* Goal - to wrap selected text with span like this:
* <span class="tooltipedurl", id="tooltip_widget_" + {someuniueID}> SELECTED TEXT </span>
* Add to the end of the editor hidden element with tooltip text like this:
* <span id="data_tooltip_widget_ + {someuniueID} style="display:none"> TOOLTIP TEXT </span>
*
*/
/**
* ================= ALGORITHM ==================
* If some text selected, or if we have caret inside span with class tooltipedurl.
* We got plugin buton - active.
* On click we see popup form with two fields.
* first with selected text, (it is hidden, user shouldn't be able to modify it from popup form)
* second is the tip input(textarea filed) we load here old tip if the caret inside the span with tip.
*
* if text selected:
* we got it from the popup form {f.textFragment.value} and replace it with
* <span id=\"tooltip_widget_' + id + '\" class=\"tooltipedurl\" name="tip">'+ f.textFragment.value + '</span>
* also we create hidden span in the end of editor with tip value from the form {f.newTip.value}
* tinyMCE.activeEditor.dom.add(tinyMCE.activeEditor.getBody(), 'span', {id : 'data_tooltip_widget_' + id, style : 'display:none'}, f.newTip.value);
*
* if caret inside the span which already has tooltip
* we have in popup form current tooltip message and can edit it and put new value to the corresponding hidden span
* ed.dom.get('data_' + innerSpanId).innerHTML = f.newTip.value;
*
* if the new tip value = 0, we delete span which contains the text and delete correspondig
* hiden element with tooltip text
*
* more detailed comments i added to the script below
