How to create a "placeholder" for DIV that act like textfield?
提问by user2399158
Div don't have a placeholder attribute
Div 没有占位符属性
<div id="editable" contentEditable="true"></div>
I want <Please your enter your Name>to show in DIV when the User backspace the whole text in the DIV, or no text on inside, How can I do it?
<Please your enter your Name>当用户退格 DIV 中的整个文本时，我想在 DIV 中显示，或者里面没有文本，我该怎么做？

Here is a pure CSS only solution:-
这是一个纯 CSS 解决方案：-
<div contentEditable=true data-ph="My Placeholder String"></div>
<style>
[contentEditable=true]:empty:not(:focus):before{
content:attr(data-ph)
}
</style>
Here, we basically select all contentEditable<divs>that are empty & blurred. We then create a pseudo element before the CSS selection (the editable div) and fix our placeholder text (specified the data-phattribute) as its content.If you are targeting old school CSS2 browsers, change all occurrences of data-phto title
Correction.......the :emptyselector is not supported in IE version 8 and earlier.
在这里，我们基本上选择所有contentEditable<divs>空的和模糊的。然后我们在 CSS 选择（可编辑 div）之前创建一个伪元素，并将占位符文本（指定data-ph属性）固定为其内容。如果您的目标是旧式 CSS2 浏览器，data-phtitle
请将所有出现的 更改为更正....... :emptyIE 8 及更早版本不支持选择器。

在 JavaScript 中
jQuery.fn.selectText = function(){

var element = this[0];
console.log(this, element);
if (doc.body.createTextRange) {
var range = document.body.createTextRange();
range.moveToElementText(element);
range.select();
} else if (window.getSelection) {
var selection = window.getSelection();
var range = document.createRange();
range.selectNodeContents(element);
