java Spring表单输入不能被禁用

Spring form input can't be disable

提问by Jerome Campeaux

I want to disable a <form:input>with the attribute disabled, but it's not working.

我想在禁用<form:input>属性的情况下禁用 a，但它不起作用。

<td class="value">
                <sec:authorize access="hasAnyRole('ROLE_EDIT_DEVICE_INSTALL_DATE')">
                    <form:input path="installDt"  maxlength="10" size="10"  cssClass="installDatePicker" /> 
                    <form:errors path="installDt" cssClass="errormsg" />
                </sec:authorize>
                <sec:authorize access="!hasAnyRole('ROLE_EDIT_DEVICE_INSTALL_DATE')">
                    <form:input path="installDt"  maxlength="10" size="10"  cssClass="installDatePicker" disabled="disabled" /> 
                    <form:errors path="installDt" cssClass="errormsg" />
                </sec:authorize>  
</td>

Does anybody have any idea to solve it ?

I remove the cssClass date picker and set the disabled boolean to true and it works

我删除了 cssClass 日期选择器并将禁用的布尔值设置为 true 并且它可以工作

To disable it, use disabled=true. It accepts true|false.

要禁用它，请使用disabled=true. 它接受真|假。

<form:input path="installDt"  maxlength="10" size="10"  cssClass="installDatePicker" disabled="true" />

When I try to do input disable with disabled="true", the data is null at core code, but when I try it with readonly, it did this properly.

当我尝试使用 禁用输入时disabled="true"，核心代码中的数据为空，但是当我尝试使用 readonly 时，它正确地执行了此操作。

Try readonly="readonly"

尝试 readonly="readonly"

When I place disabled="disable"it won't work

当我放置disabled="disable"它时它不起作用

When I place disabled="true"the value in the receiving end is null

当我把disabled="true"值放在接收端时为空

When I place readonly="true"It works for me.

当我放置readonly="true"它时它对我有用。
