Question

它在我单独的php文件中的工作方式不起作用，我首先在代码上进行了实验。我正在尝试在选中/取消选中特定复选框时启用/禁用输入框。 这些是我的代码。请帮我。它假设工作正常吗？它已经在我的单独文件上工作了。但是当我将它应用于我的实际编码文件时却没有。

我无法弄清楚出了什么问题。：（

html with php（checboxes code）

echo '<table style="border-radius:6px;border-color: FFFFFF;width:700; text-align:center" border="1" cellspacing="0" cellpadding="3">

<tr><th style="font:11pt/15pt Helvetica, sans-serif; color: #FFFFFF; ">
**<input type="checkbox" name="mon" id="mon" value="Monday" onclick="javascript:Mon_Select()"/>** Monday</th>

<th style="font:11pt/15pt Helvetica, sans-serif; color: #FFFFFF; ">
**<input type="checkbox" name="tues" id="tues" value="Tuesday" onclick="javascript:Tues_Select()">** Tuesday</th>

<th style="font:11pt/15pt Helvetica, sans-serif; color: #FFFFFF; ">
**<input type="checkbox" name="wed" id="wed" value="Wednesday" onclick="javascript:Wed_Select()">** Wednesday</th>

<th style="font:11pt/15pt Helvetica, sans-serif; color: #FFFFFF; ">
**<input type="checkbox" name="sat" id="sat" value="Saturday" onclick="javascript:Sat_Select()">** Saturday</th>

这些是我要启用/禁用的输入框

Answer 1

                         <td>
                         <label for id="Start_Mon" style="font:9pt/11pt Helvetica, sans-serif; color: #FFFFFF;">Start Time: <br>
                         <input type="time" style="width:100; height:20" name="Start_Mon" id="Start_Mon" disabled/></label>
                         </td>

你给了一个标签id ='Start_Mon' 你应该把它给它是

的输入元素

<input type="time" id='Start_Mon' style="width:100; height:20" name="Start_Mon" id="Start_Mon" disabled/></label>

在上面的代码中更改所有内容

需要将

id赋予输入字段而不是标签

没有更多的澄清请问!!!

Answer 2

而不是在你的html：

onclick="javascript:Mon_Select()"

这样做：

onclick="Mon_Select()"

第一个是无效的js代码（仅适用于网址），第二个有效。

编辑此外，根据sanjeev的建议，从id删除<labels>个属性

希望这会有所帮助，欢呼

如果选中/取消选中特定复选框，如何正确启用/禁用输入框？
