jQuery submit（）未被调用

Question

我尝试覆盖提交行为的<form>，因此我使用下一个代码：

<script type="text/javascript">
    $(function () {
        var form = $("#FilterForm");

        form.submit(function () {
            alert("Submit");

            $.ajax({
                url: form.attr("action"),
                type: 'POST',
                data: new FormData(this),
                processData: false,
                contentType: false,
                success: function (response) {
                    alert(response);
                    $('#Container').html(response);
                },
                error: function () {
                    $('#Container').html(loadingFailedStr);
                },
                timeout: 15000
            });

            return false;
        })
    });
</script>

此脚本块位于我的表单之后。在部分视图中声明此表单：

<div class="panel card-0">
    <div class="panel-body">
        @using (Html.BeginForm("TasksGridViewPartial", "Tasks", new { StaffId = staffId, StageId = stageId }, FormMethod.Post, new { id = "FilterForm", enctype = "multipart/form-data" }))
        {
            <fieldset>
                <div class="form-group row">
                    <div class="col-md-2 col-sm-6">

                </div>
            </fieldset>
        }
    </div>
</div>

我渲染这个部分视图，调用@Html.Action("FilterPartial") 最有趣的是我检查了文档就绪事件中的form变量，并将其声明为需要。但submit仍未被调用 问题可能在哪里？

Answer 1

return false是不够的，您还需要阻止默认值：

$(function () {
        var form = $("#FilterForm");

        form.submit(function (e) { // Pass the event to the function
            e.preventDefault(); // Stop the form submitting.

            $.ajax({
                url: form.attr("action"),
                type: 'POST',
                data: new FormData(this),
                processData: false,
                contentType: false,
                success: function (response) {
                    alert(response);
                    $('#Container').html(response);
                },
                error: function () {
                    $('#Container').html(loadingFailedStr);
                },
                timeout: 15000
            });

            return false;
        })
    });
