将光标设置在可编辑内容的末尾

Question

我有一个简单的可编辑内容，其中包含带有标签的文本...当插入标签时，单词将替换为其中的跨度...

<div contenteditable=true>
      text text text <span class="tag">tag</span> 
</div>

这就是结果（当用户按空格键时，标签被包含标签文本的跨度替换；这在键入时发生）

然后，我需要将光标放在可编辑内容的末尾（跨度之外），以便让用户继续输入...

我已经能够将光标移动到最后，但只能移动到跨度内...

我用兰吉。

Answer 1

这可能有效

function moveCursorAtTheEnd(){
    var selection=document.getSelection();
    var range=document.createRange();
    var contenteditable=document.querySelector('div[contenteditable="true"]');

    if(contenteditable.lastChild.nodeType==3){
      range.setStart(contenteditable.lastChild,contenteditable.lastChild.length);
    }else{
      range.setStart(contenteditable,contenteditable.childNodes.length);
    }
    selection.removeAllRanges();
    selection.addRange(range);

  }

这也更简单https://gist.github.com/al3x-edge/1010364

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
    }
}
