Question

我有一个示例列表，我正在使用javascript选择的插件。

在我所见过的所有教程中，它们都是在$ {document）.ready函数中启动选择的，但是每当我尝试这样做时，都会给我一个错误： “未捕获的类型错误...选择的不是函数”。

如果我在外面启动，它会正常工作。

下一个问题是，如果我尝试使用val（“”）。trigger（“ chosen：updated”）重置列表它什么也没做。

我的代码如下：

         <asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server">
    </asp:Content>


        <asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">


            <script src="http://code.jquery.com/jquery-1.8.3.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/chosen/1.8.7/chosen.jquery.js"></script>
    <link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/chosen/1.8.7/chosen.css">


            <select class="chosen-select" data-placeholder="Search for Numbers" style="width: 300px; height: 20px">
                <option value=""></option>
                <option value="1">1</option>
                <option value="2">2</option>
                <option value="3">3</option>
                <option value="4">4</option>
                <option value="5">5</option>
            </select>
            <button id="btn">click me to reset</button>
            <script type="text/javascript">
                $(document).ready(function () {
                    $('.chosen-select').chosen();
                });


                $("#btn").click(function () {
                    console.log("Button Clicked To Reset");
                    $('.chosen-select').val("").trigger("chosen:updated");
                    $('.chosen-select').val("").trigger("liszt:updated");

                });

            </script>
        </asp:Content>

我犯了一些简单的错误吗？是加载jquery还是选择了导致问题的那一个？

任何帮助将不胜感激。

尝试更改此内容：

<script src="http://code.jquery.com/jquery-1.8.3.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/chosen/1.8.7/chosen.jquery.js"></script>
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/chosen/1.8.7/chosen.css">

在这里：

<script src="https://code.jquery.com/jquery-1.8.3.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/chosen/1.8.7/chosen.jquery.js"></script>
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/chosen/1.8.7/chosen.css">
<script type="text/javascript">
        var jq183 = jQuery.noConflict();
</script>

并更改此内容：

$(document).ready(function () {
    $('.chosen-select').chosen();
});

$("#btn").click(function () {
    console.log("Button Clicked To Reset");
    $('.chosen-select').val("").trigger("chosen:updated");
    $('.chosen-select').val("").trigger("liszt:updated");
});

在这里：

<script type="text/javascript">
    jq183(document).ready(function () {
      jq183('.chosen-select').chosen();

      jq183("#btn").click(function () {
        console.log("Button Clicked To Reset");
        jq183('.chosen-select').val("").trigger("chosen:updated");
        jq183('.chosen-select').val("").trigger("liszt:updated");
      });
    });
</script>

如果有效，我可以详细说明出了什么问题以及对您而言更清洁的解决方案。让我知道怎么回事。

selected-select不在document.ready中启动。无法重置选择的选择
