Question

我正在使用jquery UI组合框，它在这里不起作用是我的代码，它给出了以下错误，我在firefox控制台中看到。

错误

TypeError：input.data（“autocomplete”）未定义 [打破此错误]

input.data（“autocomplete”）._ renderItem = function（ul，item）{

的Javascript

 (function ($) {
    $.widget("ui.combobox", {
        _create: function () {
            var input,
                self = this,

                    // pass empty string as value to search for, displaying all results
                    input.autocomplete("search", "");

        destroy: function () {

            this.element.show();
            $.Widget.prototype.destroy.call(this);
        }
    });
})(jQuery);

$(function () {

    $("#combobox").combobox();



});

HTML

<div class="ui-widget">

<select id="combobox">
        @foreach (var item in Model)
        {
            <option value="@item.Name">@item.Name</option>
        }
</select>

我不知道为什么但不起作用。请帮帮我

Answer 1

自动填充功能与elr_notify.js冲突，因此已解决

Answer 2

检查你是否在布局页面和当前页面中调用了相同的jquery js文件，转到共享文件夹并查找视图并检查相应的布局页面，这是由于冲突造成的
