html的解决方案:

<选择聚焦事件= " this.blur ();" >

javascript的:

selectElement。addEventListener(“焦点”,selectElement。模糊,真正的); selectElement。attachEvent(“焦点”,selectElement.blur);/ /谢谢,IE

删除:

selectElement。removeEventListener(“焦点”,selectElement。模糊,真正的); selectElement.detachEvent(“焦点”,selectElement.blur);/ /谢谢,IE

编辑:增加删除方法

您可以在提交时重新启用选择对象。

EDIT:也就是说，通常禁用select标签(带有disabled属性)，然后在提交表单之前自动重新启用它:

jQuery示例:

禁用: $ (" # yourSelect”)。道具(“禁用”,真正的); 在提交前重新启用GET / POST数据: $ (" # yourForm”)。On ('submit'， function() { $ (" # yourSelect”)。道具(“禁用”,假); })；

此外，您可以重新启用每个禁用的输入或选择:

$('#yourForm').on('submit', function() {
    $('input, select').prop('disabled', false);
});

简单的CSS解决方案:

select[readonly]{
    background: #eee;
    cursor:no-drop;
}

select[readonly] option{
    display:none;
}

这导致在选择是灰色的漂亮的“禁用”光标悬停 在选择选项列表是“空”，所以你不能改变它的值。

简单地说，在提交表单之前删除disabled属性。

    $('form').submit(function () {
        $("#Id_Unidade").attr("disabled", false);
    });

当您计划将选择设置为只读时，请将选择设置为禁用，然后在提交表单之前删除禁用属性。

            // disallow further editing of fields once save operation is underway
            // by making them readonly
            // you can also disallow form editing by showing a large transparent

            jQuery("form.anyForm").find('input[type=text], textarea, select').attr('ReadOnly','True');

    set_disabled_elem_value('address', 'address');

}); // end of $(document).ready function

您应该禁用select元素，但同时添加另一个具有相同名称和值的隐藏输入。

如果您重新启用SELECT，您应该将其值复制到onchange事件中的隐藏输入，并禁用(或删除)隐藏输入。

下面是一个演示:

$('#mainform').submit(function() { $('#formdata_container').show(); $('#formdata').html($(this).serialize()); return false; }); $('#enableselect').click(function() { $('#mainform input[name=animal]') .attr("disabled", true); $('#animal-select') .attr('disabled', false) .attr('name', 'animal'); $('#enableselect').hide(); return false; }); #formdata_container { padding: 10px; } <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <div> <form id="mainform"> <select id="animal-select" disabled="true"> <option value="cat" selected>Cat</option> <option value="dog">Dog</option> <option value="hamster">Hamster</option> </select> <input type="hidden" name="animal" value="cat"/> <button id="enableselect">Enable</button> <select name="color"> <option value="blue" selected>Blue</option> <option value="green">Green</option> <option value="red">Red</option> </select> <input type="submit"/> </form> </div> <div id="formdata_container" style="display:none"> <div>Submitted data:</div> <div id="formdata"> </div> </div>
