禁用asp.net按钮将禁用按钮的验证 [英] Disabled asp.net button disables validation for button

问题描述

我有一个aspx页面，其中包含一个复选框和一个按钮.默认情况下，该按钮处于禁用状态，直到用户选中该复选框.当我向按钮添加属性enabled ="false"时，它似乎删除了验证.启用按钮后，我仍然希望验证工作.这是不同部分的代码和标记.

I have an aspx page that contains a checkbox, and a button. The button is disabled by default until the user checks the checkbox. It looks like when I add the attribute enabled="false" to the button, it removes the validation. When the button is enabled, I still want the validation to work. Here is the code and markup for the different parts.

复选框:

<asp:CheckBox runat="server" ID="termsCheckBox" />
<label style="display: inline;">
I agree to the Terms & Conditions</label>

按钮:

<asp:Button runat="server" ID="registerButton" OnClick="registerButton_Click1" 
Text="Register" Enabled="false" ValidationGroup="accountValidation" />

jQuery:

<script type="text/javascript" language="javascript">
$(document).ready(function () {
    $('#<%=termsCheckBox.ClientID %>').click(function () {
        var checked = $(this).val();

        if (checked != undefined)
            $('#<%=registerButton.ClientID %>').removeAttr('disabled');
        else
            $('#<%=registerButton.ClientID %>').attr('disabled', 'disabled');
    });
});
</script>

推荐答案

我认为，如果您启用/禁用了CheckBox服务器端事件而不是客户端上的按钮，那么它将起作用，因为相关的客户端验证代码将是生成以为按钮的ValidationGroup运行

I think it would work if you enabled/disabled the button on the checkBox server-side event rather than client side since the associated client-side validation code will be generated to run for ValidationGroup of the button
