javascript - asp.net javascript mvc - 如何从内页获取 javascript 以从外页清除元素？

Question

我想要从“内部”mvc 表单调用的 javascript 单击事件来清除“外部”/“父”表单的元素，但单击清除不会产生任何结果（参见线框）。Javascript 适用于外部形式，但在内部形式的脚本文件引用中调用时不起作用，尽管我知道脚本已正确连接 b/c 脚本的其他行为正在发生。：

$("#clearField").on('click', function ()
{
    document.getElementById("playerCardNumber").value = "";
});

环境：asp.net mvc

外部/父 cshtml 页面的代码：

@model adminLte.Models.playerCardData

<section class="content">

            <div class="inputPlayerInfo">
                @using (Ajax.BeginForm("WriteToGroup", "IT", new AjaxOptions  //action, view
                {
                    HttpMethod = "GET",
                    InsertionMode = InsertionMode.Replace,
                    UpdateTargetId = "innerPlayerInfoForm", //css tag (see below)
                    OnComplete = "ReturnData",
                    OnBegin = "ClearResults",
                    LoadingElementId = "divloading"
                }))
                {
                        @Html.ValidationSummary(true, "", new { @class = "text-danger" })
                        <div class="divTable playerGroupTbl">

                                    <div class="divTableCell">

                                        @Html.ValidationMessageFor(model => model.playerCardNumber , "", new { @class = "text-danger" })

部分视图的代码：

    {

        HtmlHelper.UnobtrusiveJavaScriptEnabled = true;

        <div class="divTable playerGroupTbl">

                        <button onclick="ClearResults()" class="btn btn-default btn-lg" id="clearField">Clear Selected Data</button>

            </div>

            <div id="PlayerGroupInsertStatus"></div>
            @Scripts.Render("~/scripts/renderJS.js")

外部js文件：

$('#playerEvent').selectpicker({
    size: 4
});


$('#formEvent_playerEvent').selectpicker({
    size: 4
});

function ReturnData() {
    $('#PlayerGroupInsertStatus').show();
}

function beforeSend() {

    var PlayerID = document.getElementById("PlayerID").value;

}

$("#clearField").on('click', function ()
{
    document.getElementById("playerCardNumber") = "";
});
