当我进入该字段时，如何让表单值消失? [英] How do I get form values to disappear when I enter the field?

问题描述

我正在制作一个包含大约八个输入字段的简单表单.我希望字段中的初始值指示人们应该输入的内容.例如 value="name" 以便人们知道在那里输入名称.

I am making a simple form with about eight input fields. I want the initial value in the field to indicate what people are supposed to enter. For example value="name" so that people know to enter there name there.

我的问题是，当他们进入该字段时，如何让初始值消失，以便初始值只是一个提示，而不是他们必须在输入名称之前擦除的永久值?

My question though is how do you get the initial value to vanish when they enter that field so that the initial value is only a hint and not a permanent value that they have to erase before they can type in their name?

谢谢！

推荐答案

将默认"值设置为名称".然后，使用 javascript 和 'onfocus' 事件清除该字段.

Set the 'default' value to "Name". Then, using javascript and the 'onfocus' event, clear the field.

所以你会:

<input type="textbox" value="Name" onfocus="if (this.value=='Name') this.value='';"/>
