禁用Spring中的复选框并将检查的值传递给控制器

Question

Hello I have to disable checkbox in spring html form and pass the checked value to controller. I use the below code, but the problem is that I am not able to pass the checked value to controller when the disabled attribute is set to true

<form:checkbox path="agreementCats" disabled="true" value="${x.value}" class="category-checkboxes" id="agreementCat-cb-${i.index}" /><label class="control-label" for="agreementCat-cb-${i.index}">&nbsp;${x.label}</label>
<form:hidden path="agreementCats" value="${x.value}" />

The above code sends all the values to controller. Please help!!

Answer 1

代替disabled="true"将其更改为readonly= "true"如果您插入，Disabled不会发送值，但是readonly会发送值。

Answer 2

in HTML have two tag with similar meaning but different context is Disabled and ReadOnly.

• disabled : Disabled the input in the form and the data isn't in form query.
• readonly : Omit the user UI interaction but the input is in form query.

Try use readonly tag instead disabled, I hope this help you.

That solution works for all inputs except checkbox ... Checkbox can't use readonly, but you can do a little trick, is a dirt trick, but it can you help to not permit user touch check box.

If you know in server side what checkbox can be edited, try this code:

<input type="checkbox" <c:if test="condition">onclick="return false;"</c:if> ></input>

That code not permit user click the checkbox if the condition is true. Maybe with this can solved your problem.
