Question

我有CRUD，想要添加Sweet Alert确认框。但我只是将它添加到创建表单。显然很简单，我只是想这样：

输入数据
点击提交按钮
出现甜蜜警报确认
点击“是”＆＃39;
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;
  }
});

});

实际上，脚本正在运行，甜蜜警报也出现了，但表格提前提交但没有给我机会确认，我已经尝试过每个导师但没有一次工作。

要解决此问题，您需要始终停止jQuery代码中submit事件处理程序的默认行为。

然后，当用户确认他们的选择时，您可以直接在if语句中从DOM元素提交表单，如下所示：

＆＃13;

$("#tmbhunit").submit(function(e) {
  e.preventDefault();
  var nm_unit = $("#namaunit").val();
  var almtunit = $("#almtunit").val();
  var form = this;

  swal({
    title: "Are you sure?",
    type: "warning",
    showCancelButton: true,
    confirmButtonColor: "#DD6B55",
    confirmButtonText: "Yes!",
    cancelButtonText: "Cancel",
    closeOnConfirm: true
  }, function(isConfirm) {
    if (isConfirm) {
      form.submit();
    }
  });
});

        </div>
      </div>
    </div>

        </div>
      </div>
    </div>
  </div>
</form>

＆＃13;

Answer 2

在提交之前使用而不是像下面的提交功能

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

表格提交不等待甜蜜警报确认
