我需要验证我的 ASP MVC3 视图中的一些字段，并尝试使用 jQuery 来执行此操作。jQuery.val()方法可以很好地从输入字段中提取 、 和 ，但是该accountNumber字段refNumber的值始终为 。ownerMasteragentId""

我一遍又一遍地查看代码中的拼写错误，但没有找到。希望另一双眼睛能解决问题。

仅供参考 - 如果我将下面的.val()on更改为 hide 方法有效并且该字段消失，这意味着我输入了正确的选择器。$('#AgentId').val().hide()

jQuery

function ValidateFields(transactionType) {
    var msg = "";
    var refNumber = $('#RefNumber').val();
    var ownerMaster = $('#OwnerMasterAgentId').val();
    var accountNumber = $('#AccountNumber').val();
    var agentId = $('#AgentId').val(); //When the agentId variable an selector + val() are
                                       //evaluated here both have a value of ""

ASP MVC 剃刀

                <div class="M-editor-label">
                    @Html.LabelFor(model => model.RefNumber)
                    <span class="alwaysReq"> @Html.Raw("*")</span>
                </div>
                <div class="M-editor-field">
                    @Html.TextBoxFor(model => model.RefNumber, new { maxlength = 9, @class = "staticData" })
                </div>
                <div class="M-editor-label">
                    @Html.LabelFor(model => model.OwnerMasterAgentId)
                    <span class="req">@Html.Raw("*")</span> 
                </div>

我没有看到问题，

  1. 但是你的页面中有没有其他 html 元素有 id=AgentId
  2. 当您更改字段的文本时，它是否会在萤火虫中发生变化

实际上，您不必创建自己的验证，您可以使用提供服务器端和客户端验证的数据注释验证

尝试这个

var agentId=$('#@Html.FieldIdFor(model => model.AgentId)').val();
