Sweetalert - 验证无效 + 表单未提交

Question

我正在尝试实施 sweetalert2 但由于某些原因它不应用常规 html 验证（即 required='true' 不起作用），我没有收到字段为空的错误消息。

没有swall2，确实会提示我字段为空的错误。

此外，一旦我在 swall 对话框中确认我要继续 ("Yes, submit it!")，它不会提交表单。

我错过了什么？

HTML:

<form>
   <label>Last Name</label>
   <input type="text"  required="true"/>
   <input class="btnn" type="submit" name="submit" id="btn-submit"/>
</form>

Javascript:

$('#btn-submit').on('click', function(e) {
    e.preventDefault();
    var form = $('form');
    swal.fire({
        title: "Are you sure?",
        type: "warning",
        showCancelButton: true,
        confirmButtonColor: "#DD6B55",
        confirmButtonText: "Yes, submit it!",
        closeOnConfirm: false
    }, function(isConfirm) {
        if (isConfirm) form.submit();
    });
});

文档说在它迁移到 sweetalert2 之后结构已经从回调方法改变

swal(
      {title: 'Are you sure?', showCancelButton: true}, function(isConfirm) {
      if (isConfirm) {
      // handle confirm
      } else {
      // handle all other cases
    }
  }
)

基于承诺的方法

Swal.fire({title: 'Are you sure?', showCancelButton: true}).then(result => {
 if (result.value) {
  // handle Confirm button click
 // result.value will contain `true` or the input value
 } else {
   // handle dismissals
   // result.dismiss can be 'cancel', 'overlay', 'esc' or 'timer'
 }
})

你可以这样做。

                $('#btn-submit').on('click',function(e){
                e.preventDefault();
                var form = $('form');
                console.log("hello");
                swal.fire({
                    title: "Are you sure?",
                    type: "warning",
                    showCancelButton: true,
                    confirmButtonColor: "#DD6B55",
                    confirmButtonText: "Yes, submit it!",
                }).then(function (result){
                    if(result.value === true){
                    console.log("Submitted");
                    form.submit();
                  }
                });
            });

您可以在提交表单时调用 swal，目前在单击提交按钮时会在表单提交之前调用 swal 确认框。 JSFiddle Link : sweetalert 试试下面的代码：

                $('#form1').on('submit',function(e){
                    e.preventDefault();
                    var form = $('form');
                    swal.fire({
                        title: "Are you sure?",
                        type: "warning",
                        showCancelButton: true,
                        confirmButtonColor: "#DD6B55",
                        confirmButtonText: "Yes, submit it!",
                        closeOnConfirm: false
                    }, function(isConfirm){
                      
                        if (isConfirm) form.submit();
                    });
                });

<!DOCTYPE html>
<html>
<head>
 <title></title>
</head>
<body>
<form name="form1" id="form1" method="post">
<label for="">Last Name</label><span class="required">  *</span>
<input type="text"  required />
<input class="btnn" type="submit" name="submit" id="btn-submit"/>
