使用单选按钮触发动作 [英] Using radio button to trigger an action

问题描述

我正在做一个项目，需要两个单选按钮进行日期选择.一个单选按钮获取系统日期并打印，但是另一个按钮在我选择时希望用户能够输入日期(基本上我想要当我单击第二个单选按钮时，将出现一个文本字段.)我是html编码的新手，所以如果有人可以帮助我，我了解了javascript和jquery，但我看到的示例无法提供任何帮助. 我已经添加了单选按钮

I am doing a project where I need two radio buttons for date selection.One radio button takes the system date and prints but the other button when I select,I want the user to be able to enter the date(basically I want a text field to appear when I click on the second radio button).I am new to html coding so please if anyone could help me.I read about javascript and jquery but the examples that I saw werent able to provide any help. I have already added the radio buttons

<table border="1" width="100%">
<tr>
 <th> Date</th>
</tr>
<td>
  Current date<input type="radio" name="zing" id="foo" checked/>
  Add date<input type="radio" name="zing" id="bar"/></td>
</table>

请有人给我一个主意.

推荐答案

<table border="1" width="100%">
<tr>
 <th> Date</th>
</tr>
<td>
  Current date<input type="radio" name="zing" id="foo" checked/>
  Add date<input type="radio" name="zing" id="bar"/>
<input type='text' id='txtDate' style='display:none'/>
</td>
</table>

然后在脚本下方写下

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js" ></script>
<script>
$(document).ready(function(){
  $("#bar").change(function(){
       $("#txtDate").show();
  });
$("#foo").change(function(){
       $("#txtDate").hide();
  });
});
</script>
