javascript - 表单提交不等待甜蜜警报确认

Question

我有 CRUD，想添加带有 Sweet Alert 的确认框。但我只是将它添加到 Create Form 中。显然很简单，我只是想这样:

• 输入数据
• 点击提交按钮
• Sweet Alert 确认出现
• 点击"is"
• 数据存储到数据库
• 返回阅读表

这是我的代码:

<!-- Form -->
<form role="form" method="post" class="form-horizontal" id="tmbhunit" action="<?= base_url() ?>C_unit/create">
<!-- Card Icon -->
<div class="card-header card-header-icon" data-background-color="red">
    <i class="material-icons">account_balance</i>
</div>
<!-- End Card Icon -->

<!-- Card Content -->
<div class="card-content">
    <!-- Card Title -->
    <h4 class="card-title">Tambah Data</h4>
    <!-- End Card Title -->
    <hr>

    <!-- Label Input -->
    <div class="row">
        <label class="col-sm-2 label-on-left" for="namaunit">Nama Unit</label>
        <div class="col-sm-4">
            <div class="form-group label-floating is-empty">
                <label class="control-label"></label>
                <input type="text" class="form-control" id="namaunit" name="nm_unit" required placeholder="Masukan nama unit..">
            </div>
        </div>
    </div>
    <!-- End Label Input -->
    <!-- Label Input -->
    <div class="row">
        <label class="col-sm-2 label-on-left" for="almtunit">Alamat Unit</label>
        <div class="col-sm-4">
            <div class="form-group label-floating is-empty">
                <label class="control-label"></label>
                <input type="text" class="form-control" id="almtunit" name="alamat" required placeholder="Masukan alamat unit..">
                <br>
                <input type="submit" name="submit" id="btn-submit" class="btn btn-primary btn-fill" value="Tambah" />
                <input type="button" name="cancel" class="btn btn-warning btn-fill" value="Cancel" onclick="history.back()" />
            </div>
        </div>
    </div>
    <!-- End Label Input -->

</div>
<!-- End Card Content -->
</form>
<!-- End Form -->

这是javascript:

$("#tmbhunit").submit( function () {

var nm_unit = $("#namaunit").val();
var almtunit = $("#almtunit").val();

swal({
    title: "Are you sure?",
    type: "warning",
    showCancelButton: true,
    confirmButtonColor: "#DD6B55",
    confirmButtonText: "Yes!",
    cancelButtonText: "Cancel",
    closeOnConfirm: true
}, function(isConfirm){
  if (isConfirm) {
    event.preventDefault();
        return true;
  } else {
    return false;
  }
});

});

其实脚本是可以运行的，sweet alert也出现了，但是表格提前提交了，没有给我确认的机会，我试过所有的导师，但一次都没有成功。

在提交前使用而不是像下面的提交函数

 jQuery("body").on("beforeSubmit", "form#tmbhunit", function() {
    // You logic
    return false;
 });
