javascript – 在contentEditable元素中插入HTML元素

// get the selection range (or cursor     position)
var range = window.getSelection().getRangeAt(0); 
// create a span
var newElement = document.createElement('span');
newElement.id = 'myId';
newElement.innerHTML = 'Hello World!';

// if the range is in #myDiv ;)
if(range.startContainer.parentNode.id==='myDiv') {
   // delete whatever is on the range
   range.deleteContents();
   // place your span
   range.insertNode(newElement);
}

我没有IE但在firefox,chrome和safari上工作正常.也许你想玩range.startContainer只有在contentEditable div上进行选择才能继续.

编辑：根据quirksmode range intro你必须改变window.getSelection()部分是IE兼容.

var userSelection;
if (window.getSelection) {
    userSelection = window.getSelection();
}
else if (document.selection) { // should come last; Opera!
    userSelection = document.selection.createRange();
}
