jQuery .validate()submitHandler没有触发

Question

我正在加载一个对话框,其中包含使用Bootbox.js即时构建的表单,我正在使用jQuery validate插件验证用户输入.

验证工作正常,但submitHandler在成功填写表单时会被忽略.

出了什么问题？

submitHandler: function(form) {
    alert("Submitted!");
    var $form = $(form);
    $form.submit();
}

请参阅下面的完整示例.我查看了其他提出类似问题的帖子.不幸的是,他们似乎在页面上呈现了表单,而我正在通过jQuery渲染.

$(document).on("click", "[data-toggle=\"contactAdmin\"]", function() {
  bootbox.dialog({
    title: "Contact admin",
    buttons: {
      close: {
        label: 'Close',
        className: "btn btn-sm btn-danger",
        callback: function() {}
      },
      success: {
        label: "Submit",
        className: "btn btn-sm btn-primary",
        callback: function() {
          $("#webteamContactForm").validate({
            rules: {
              requestType: {
                required: true
              }
            },
            messages: {
              requestType: {
                required: "Please specify what your request is for",
              }
            },
            highlight: function(a) {
              $(a).closest(".form-group").addClass("has-error");
            },
            unhighlight: function(a) {
              $(a).closest(".form-group").removeClass("has-error");
            },
            errorElement: "span",
            errorClass: "help-blocks",
            errorPlacement: function(error, element) {
              if (element.is(":radio")) {
                error.appendTo(element.parents('.requestTypeGroup'));
              } else { // This is the default behavior 
                error.insertAfter(element);
              }
            },
            submitHandler: function(form) {
              alert("Submitted!");
              var $form = $(form);
              $form.submit();
            }
          }).form();
          return false;
        }
      }
    },

检查jsFiddle的DOM和两个问题变得明显.

1. 你的"提交" <button>是一个type="button".

2. 您的"提交"按钮位于<form></form>容器之外.

如果你想让jQuery Validate插件自动捕获click"提交"按钮的事件......

• 按钮必须是 type="submit"
• 按钮必须位于<form></form>容器内.

如果您希望插件按预期运行,则必须满足这两个条件.

您还错误地将.validate()方法放在success模式对话框"提交"按钮的回调中.

该.validate()方法仅用于初始化插件,应在创建表单后调用一次.

编辑:

在玩完这个之后,很明显Bootbox模式插件可能有一些严重的限制,干扰了表单的提交.

1. 我打开对话框后初始化Validate插件.

2. 我.valid()在"提交"中使用该方法来触发验证测试.

我可以初始化验证并按预期工作,但在实际表单提交之前,对话框将被取消.也许有一个解决方案,但在审查了Bootbox的文档后,它并不是很明显.

根据OP的解决方案......

bootbox.dialog({
    // other options,
    buttons: {
        success: {
            label: "Submit",
            className: "btn btn-sm btn-primary",
            callback: function () {
                if ($("#webteamContactForm").valid()) {
                    var form = $("#webteamContactForm");
                    form.submit();  // form submits and dialog closes
                } else {
                    return false;  // keeps dialog open
                }
            }
        }
    }
});

但是,通过直接使用提供的form参数,在使用submitHandlerjQuery Validate插件的选项时没有任何错误.

submitHandler: function (form) {
    console.log("Submitted!");
    form.submit();
}
