我有两个自动填充的下拉字段。
示例：
car_model - ＆gt; dropdown_field1
car_model_variants - ＆gt; dropdown_field2
当我在car_model字段中选择模型时，car_model_variants必须更新其值。
在我的情况下，我有index.php，您可以在其中单击一个显示模式框的按钮，然后您将找到自动填充的下拉字段。
首次尝试，当选择car_model时，car_model_variants字段正在更新其值。但如果我在car_model_variants为空时提交表单，如果我再次尝试选择car_model，它就不起作用了吗？下拉2字段未更新。以下是我的代码。
(function ($) {
$('.edit').formPopup({
'modalParams': {
'parent_container': $('div.autodeal')
},
'callback': function (settings)
{
$('.modal')
.addClass('large')
.css({'z-index': 101});
$('#used_car_car_model').change(function () {
var select = $(this);
$.ajax({
'url': '{{ path("autodeal_backend_filter_select") }}',
'data': {'carModelId': select.val(), 'carGuideOnly': 0, 'isVerified': 1, 'showCompleteName': 1},
success: function (html)
{
$('#used_car_car_model_variant').html(html);
}
});
});
},
'formSubmitParams': {
'retainFormUrl': false,
'submit_callback': function ()
{
window.location.reload();
},
'error_callback': function (form, settings)
{
$('.close, .exit', $(settings.container))
.click(function () {
window.location.reload();
});
}
}
});
})(jQuery);
这是完整的代码。
