表单输入文本在单击时消失，如果未输入任何内容，则重新出现 [英] Form Input text disappear on click and reappear if nothing has been entered

问题描述

基本上，我需要输入字段的帮助，单击该字段时，文本(值)会消失，但是如果用户未输入任何内容，它将恢复为原来的状态.

我设法使一次单击时不使用javascript就能使内部的值消失，但是如果用户没有单击内部作为字段，那么如果有人未输入任何内容，我希望有人向我指出正确的方法，该方法是如何还原回原始值仍然是空白，我知道这是最小的，但是它有点小，这让我很烦.

Basically i need help with input fields that when clicked the text (value) disappears but if the user has not entered anything in it would revert back to what was originally there.

I have managed to get the value inside to disappear once clicked without the use of javascript but would love someone to point me in the right direction of how to revert the original value back if nothing was entered in if the user did click inside as the field continues to be blank which i know is minimal but it something small that is annoying me.
