问题描述

我有以下代码演示了contenteditable属性和一个按钮,该按钮会将粗体文本插入具有contenteditable区域的段落中.我的问题是如何将焦点恢复到单击粗体后我离开的地方,如果突出显示一些文本,然后单击粗体,它将使那些文本变为粗体,但是焦点将不再存在.如果您不选择任何内容并单击粗体,则会发生相同的情况,焦点将消失,如果再次单击中断的位置,则可以键入粗体文本.

I have the following code demonstrating contenteditable property and a button that will inject bold text into the paragraph with contenteditable area. My question is how to return focus to where i left off after clicking on bold, if you highlight some text, and click bold, it'll bold those text, but the focus will not be there anymore. Same thing happens if you don't select anything and click bold, the focus will be gone and if you click where you left off again, you can type bold texts.

非常感谢您的帮助!

推荐答案

您应该使用.contents()

YOU SHOULD USE .contents()

var current;
$(function(){
    $("p[contenteditable]").focus(function() {
        current = this;
    });

    $('#bold').click(function (){
            document.execCommand('bold', false, true);
            $(current).contents().focus();
    });
});
