jquery验证阻止表单提交

Question

我不确定为什么要提交此表单。我已经复制了其他示例中的代码并将其替换为我的内容，但即使我已经输入return false

，它也会继续提交表单

当选择端口ICMP时，它不会验证其他规则并提交表单。

$("form[name='frmAddCMRow']").validate({
  /*
    showErrors: function(errorMap, errorList) {
      $.each(this.successList, function(index, value) {
        $(value).popover('hide');
      });
      $.each(errorList, function(index, value) {
        var _popover = $(value.element).popover({
          trigger: 'manual',
          placement: 'top',
          content: value.message,
          template: '<div class="popover"><div class="arrow"></div><div class="popover-inner"><div class="popover-content"></div></div></div>'
        });
        _popover.data('bs.popover').options.content = value.message;
        $(value.element).popover('show');
      });
    },
    */
  submitHandler: function() {

    var formdata = $('form').serialize();
    console.log(formdata);

    return false;

  },
  rules: {
    src: {
      required: true,
      messages: {
        required: "Please enter Source IP",
      }
    },
    dst: {
      required: true,
      messages: {
        required: "Please enter Destination IP",
      }
    },
    ports: {
      required: function() {
        return $("form[name='frmAddCMRow'] select[name='protocol']").val() != "ICMP";
      },
      messages: {
        required: "Please enter Ports",
      }
    },
  },
});

Answer 1

选择器name中表单的$("form[name='frmAddCMRow']")与实际表单的name frm_rename_commsmatrix不匹配。因此，jQuery Validate插件未在表单上初始化。

请尝试$("form[name='frm_rename_commsmatrix']")。
