jQuery:从输入数组获取价值

本文介绍了jQuery:从输入数组获取价值的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我们采用以下形式:

<form> ... <table width="100%" cellspacing="0" class="datagrid_ppal"> <tbody> <tr> <th scope="row">Area 1 <input name="config_line" type="hidden" value="0,5,50" /></th> <td class="gantt"> </td> <td class="gantt"> </td> <td class="gantt"> </td> ... </tr> </tbody> </table width="100%" cellspacing="0" class="datagrid_ppal"> ... <form>

我们需要从隐藏的输入值中获取第一个，第二个或第三个.我们已经尝试过了，但是没有用:

What we need is to get the first, second or third from the hidden input value. We have tried this and didn't work:

var value = $('th').children('input:hidden').val();

有人可以帮助我们吗?我们真的很感激.

Can anyone help us? We would really appreciate it.

推荐答案

隐藏字段的值不是数组，而只是字符串:"0,5,50".

The value of your hidden field is not an array, but just the string: "0,5,50".

要使用jQuery检索该值，请使用:

To retrieve that value using jQuery use:

$('input[name=config_line]').val()

要将该字符串拆分为数组，请使用split()方法.

To split that string into an array use the split() method.

组合:

var firstValue = $('input[name=config_line]').val().split(",")[0]; // etc...
