启用禁用无线电选择的选择/下拉列表 [英] enable disable select / dropdown on radio selection

问题描述

我是JQuery的新手，请认为我是新手。我有一个PHP表单，我有一个单选按钮。根据选择的无线电，我想禁用选择/下拉列表。以下是场景：

I am very new to JQuery, please consider me as a novice. I have a PHP form where in I have a Radio button. Based on the which radio is selected I would like to disable the select / dropdown. Below is the scenario:

单选按钮：每日和其他
选择：Deity Name

Radio Button: Daily and Misc Select: Deity Name

如果用户选择Misc然后选择（Deity Name）应该被禁用，反之亦然。

If the user selects Misc then Select (Deity Name) should be disabled and vice versa.

我已经在我的页面上导入了JQuery。

I have already imported the JQuery on my page.

Header.php

!-- JQuery 1.12.3 JS -->
<script src="../js/jquery-1.12.3.min.js"></script>

HTML代码

<tr>
<td class="col-md-4"><label class="control-label">Pooja Type</label></td>
<td class="col-md-8" align="center">
<label class='radio-inline'><input type='radio' name='poojaType' value='daily' checked>Daily</label>
<label class='radio-inline'><input type='radio' name='poojaType' value='misc'>Misc</label>
</td>
</tr>
<tr>
<td class="col-md-4"><label class="control-label" for="deity">Deity Name</label></td>
<td class="col-md-8"><select class="form-control" name="deityName"> 

请建议。

推荐答案

按照以下代码：

假设您有两个单选按钮，如下所示：

Assume you have two radio buttons as below:

<input type='radio' name='radios' id='rdbDaily' value='Daily' />&nbsp;Daily
<input type='radio' name='radios' id='rdbMisc' value='Misc' />&nbsp;Misc

和一个下拉列表如下：

<select id='selectordropdown'>
    <option>Deity Name</option>
</select>

您可以使用以下jquery通过选择单选按钮启用或禁用您的下拉列表：

you can use below jquery to enable or disable your dropdown by selecting radio buttons:

$('input:radio[name="radios"]').change(function() {
    if ($(this).val()=='Daily') {
        $('#selectordropdown').attr('disabled', false);
    } 
    else if ($(this).val()=='Misc') {
        $('#selectordropdown').attr('disabled', true);
    }
});

或者您也可以使用以下jquery来启用/取消您的下拉菜单：

or you can also use below jquery to enable / disbale your dropdown:

$("#rdbDaily").click(function() {
    $("#selectordropdown").attr("disabled", false);
});

$("#rdbMisc").click(function() {
    $("#selectordropdown").attr("disabled", true);
});
