我试图按照下面的方法: http://www.asp.net/mvc/overview/older-versions/working-with-the-dropdownlist-box-and-jquery/adding-a-new-category-to-the-dropdownlist-using-jquery-ui 要添加一个模式对话框来添加一个新的值与模态对话框的组合框。但是,我不断收到以下错误:ASPMVC试图显示对话框将新项目添加到Combobox
0x800a139e - JavaScript运行时错误:无法在初始化之前调用对话框上的方法;试图调用方法 '开放'
我的代码如下:
@section Scripts {
@Scripts.Render("~/bundles/jqueryval")
<script type="text/javascript">
$(function() {
$("#genreDialog").dialog({
autoOpen: false,
width: 400,
height: 300,
modal: true,
title: 'Add Genre',
buttons: {
'Save': function() {
var createGenreForm = $('#createGenreForm');
if (createGenreForm.valid()) {
$.post(createGenreForm.attr('action'), createGenreForm.serialize(), function (data) {
if (data.Error != '') {
alert(data.Error);
}
else {
// Add the new genre to the dropdown list and select it
$('#GenreId').append(
$('<option></option>')
.val(data.Genre.GenreId)
.html(data.Genre.Name)
.prop('selected', true) // Selects the new Genre in the DropDown LB
);
$('#genreDialog').dialog('close');
}
});
}
},
'Cancel': function() {
$(this).dialog('close');
}
}
});
$('#genreAddLink').click(function() {
var createFormUrl = $(this).attr('href');
$('#genreDialog').html('')
.load(createFormUrl, function() {
// The createGenreForm is loaded on the fly using jQuery load.
// In order to have client validation working it is necessary to tell the
// jQuery.validator to parse the newly added content
jQuery.validator.unobtrusive.parse('#createGenreForm');
$('#genreDialog').dialog('open');
});
return false;
});
});
</script>
}
笔者认为:
@Html.Partial("_ChooseCityDistrict")
我PartialView:
@Html.DropDownListFor(model => model.CityDistrictID, Model.CityDistrictList, "Select Name City District", htmlAttributes: new { @class = "form-control" })
<a class="button" href="@Url.Content("~/NameCityDistricts/Create")" id="genreAddLink">Add New City District</a>
@Html.ValidationMessageFor(model => model.CityDistrictID, "", new { @class = "text-danger" })>
通过此获得任何帮助错误将不胜感激! 谢谢!
