How do I make a HTML input box default text remove AFTER starting to type
提问by Jordan Clifton
Say I have an input box with default text "name" in it. I would like for the user to click the box, the text stays in the box until the user starts to type.
假设我有一个带有默认文本“名称”的输入框。我希望用户单击该框，文本保留在框中，直到用户开始键入。
I am notlooking for code to clear the input box after focusing it.
我不是在寻找在聚焦后清除输入框的代码。
Thanks!
谢谢！

It's placeholder attribute
它是占位符属性
<input type="text" placeholder="Type your name">

What you are trying to do depends on the version of the browser you are targeting. If the customer uses a browser that support html5 then the answer from @alexndm will work. However if you are targeting a mass audience with number of browser version.
您尝试执行的操作取决于您所针对的浏览器版本。如果客户使用支持 html5 的浏览器，那么来自 @alexndm 的答案将起作用。但是，如果您针对具有多个浏览器版本的大量受众。
This article here will show how to do it the old way, i.e. using javascript. How do I get placeholder text in firefox and other browsers that don't support the html5 tag option?
此处的这篇文章将展示如何以旧方式进行操作，即使用 javascript。如何在不支持 html5 标签选项的 Firefox 和其他浏览器中获取占位符文本？
Note: the OP of the post I linked also have html5 in case you need it.
注意：我链接的帖子的 OP 也有 html5，以备不时之需。
