如何将光标移动到可内容编辑实体的末尾

我需要将插入符号移至末尾contenteditable类似于 Gmail 笔记小部件上的节点。

我在 StackOverflow 上阅读了线程，但这些解决方案基于使用输入，并且不适用于contenteditable元素。

Geowa4 的解决方案适用于文本区域，但不适用于可内容编辑的元素。

此解决方案用于将插入符号移动到可内容编辑元素的末尾。它应该适用于所有支持 contenteditable 的浏览器。

function setEndOfContenteditable(contentEditableElement)
{
    var range,selection;
    if(document.createRange)//Firefox, Chrome, Opera, Safari, IE 9+
    {
        range = document.createRange();//Create a range (a range is a like the selection but invisible)
        range.selectNodeContents(contentEditableElement);//Select the entire contents of the element with the range
        range.collapse(false);//collapse the range to the end point. false means collapse to end rather than the start
        selection = window.getSelection();//get the selection object (allows you to change selection)
        selection.removeAllRanges();//remove any selections already made
        selection.addRange(range);//make the range you have just created the visible selection
    }
    else if(document.selection)//IE 8 and lower
    { 
        range = document.body.createTextRange();//Create a range (a range is a like the selection but invisible)
        range.moveToElementText(contentEditableElement);//Select the entire contents of the element with the range
        range.collapse(false);//collapse the range to the end point. false means collapse to end rather than the start
        range.select();//Select the range (make it the visible selection
    }
}

它可以通过类似于以下的代码来使用：

elem = document.getElementById('txt1');//This is the element that you want to move the caret to the end of
setEndOfContenteditable(elem);
