如何在JavaScript中获得文本框的值 [英] How to get text box value in JavaScript

问题描述

我试图使用JavaScript从HTML文本框中获取值，但值不会在空格之后出现

例如：

 < input type =textname =txtJobvalue =software engineer> 
  

我只从上面得到：software。我使用这样的脚本：
$ b

  var jobValue = document.getElementById（'txtJob'）。value 
  

如何获得完整值：software engineer？

解决方案

+1 Gumbo：'id'是访问页面元素的最简单方法。 IE浏览器（pre version 8）如果找不到具有给定ID的任何内容，就会返回匹配name的东西，但这是一个bug。

id-vs-name不会影响这个;我怀疑发生了什么事（与示例代码相反），您已经忘记引用您的值属性：

 < ; input type =textname =txtJobvalue = software engineer> 
  

I am trying to use JavaScript to get the value from an HTML text box but value is not coming after white space

For example:

<input type="text" name="txtJob" value="software engineer">

I only get: "software" from the above. I am using a script like this:

var jobValue = document.getElementById('txtJob').value

How do I get the full value: "software engineer"?

解决方案

+1 Gumbo: ‘id’ is the easiest way to access page elements. IE (pre version 8) will return things with a matching ‘name’ if it can't find anything with the given ID, but this is a bug.

i am getting only "software".

id-vs-name won't affect this; I suspect what's happened is that (contrary to the example code) you've forgotten to quote your ‘value’ attribute:

<input type="text" name="txtJob" value=software engineer>
