Question

我有一个联系表格，当您按下发送按钮时，会打开一个弹出窗口，要求确认阅读隐私政策。
目前，如果有必填字段，则表单不会发送任何内容，但会打开弹出窗口如果仍有必填字段，我需要阻止弹出窗口打开这是代码：

＆＃13;

$('#myCheck').click(function() {
     $(this).toggleClass("checked");
});


(function($) {
    $.fn.toggleDisabled = function(){
        return this.each(function(){
            this.disabled = !this.disabled;
        });
    };
})(jQuery);

$('.checkz').click(function () {
    $('#invias').toggleDisabled();
    $('#invias').toggleClass("activ3");
    });
    
    
    $(".pex").click(function (e) {
    e.stopPropagation();
});

function checkInputs() {
  var isValid = true;
  $('input').filter('[required]').each(function() {
    if ($(this).val() === '') {
      $('#confirm').prop('disabled', true)
      isValid = false;
      return false;
    }
  });
  if(isValid) {$('#confirm').prop('disabled', false)}
  return isValid;
}

//Enable or disable button based on if inputs are filled or not
$('input').filter('[required]').on('keyup',function() {
checkInputs()
})

checkInputs()

.checkz {width:20px;

    z-index: 1999999999;
    overflow: initial;
    transition: all .15s ease-in-out;
}

.pex {width:500px;padding:30px;background:#FFF;z-index:1999999999;margin: 10% auto 0;text-align: center;}

您可以使用以下小提琴进行测试：http://jsfiddle.net/2BgdD/12/
非常感谢。

Answer 1

如果您将$5设置为全局变量，则可以在触发isValid方法之前使用它进行检查：

popupshow

您还需要调整function popupshow() { if (!isValid) return; document.getElementById("popup").style = ""; }方法：

checkInputs

如果必填字段为空，请勿打开弹出窗口
