我无法让表单验证工作

Question

我有JavaScript表格验证，它正常工作，但我需要验证形式的东西，我有一个收音机是否如果选择是，然后弹出另一个框，但我需要它，所以如果他们点击是的输入也是必需的。 所以这就是我的所有代码：

$(document).ready(function(){
  //$( "#datepicker" ).datepicker();

  //global vars
  var form = $("#closecall");
  var datepicker = $("#datepicker");
  var datepicker_info = $("#datepicker_info");
  var hr = $("#hr");
  var min = $("#min");
  var project = $("#project");
  var project_info = $("#project_info");
  var des_event = $("#event");
  var event_info = $("#event_info");
  var happened = $("#happened");
  var happened_info = $("#happened_info");
  var about = $("#about_it");
  var about_info = $("#about_info");
  var organisation = $("#organisation");
  var organisation_info = $("#organisation_info");
  var region = $("#region");
  var region_info = $("#region_info");
  var rules = $(".rules");
  var liferules = $("#liferules");
  var rules_info = $("#rules_info");
  var end_info = $("#end_info");

  //On blur
  datepicker.blur(validateDatepicker);
  project.blur(validateProject);
  des_event.blur(validateEvent);
  happened.blur(validateHappened);
  about.blur(validateAbout);
  organisation.blur(validateOrganisation);
  region.blur(validateRegion);
  liferules.blur(validateLiferules);

  //On key press
  datepicker.keyup(validateDatepicker);
  project.keyup(validateProject);
  des_event.keyup(validateEvent);
  happened.keyup(validateHappened);
  about.keyup(validateAbout);
  organisation.keyup(validateOrganisation);
  region.keyup(validateRegion);
  liferules.keyup(validateLiferules);

  //On Submitting
  form.submit(function(){
    if(validateDatepicker() & validateProject() & validateEvent() & validateHappened() & validateAbout() & validateOrganisation() & validateRegion() & validateLiferules()){
      $("#submit").prop("disabled", true);
      $("#submit").prop("value", "Sending...");
      end_info.removeClass("info_error");
      return true;
    }else{
      return false;
    }
  });

  //validation functions
  function validateDatepicker(){
    //it's NOT valid
    if(datepicker.val().length < 1){
      datepicker.addClass("error");
      hr.addClass("error");
      min.addClass("error");
      datepicker_info.addClass("info_error");
      end_info.addClass("info_error");

      return false;
    }
    //it's valid
    else{
      datepicker.removeClass("error");
      hr.removeClass("error");
      min.removeClass("error");
      datepicker_info.removeClass("info_error");
      end_info.removeClass("info_error");
      return true;
    }
  }

  function validateProject(){
    //it's NOT valid
    if(project.val().length < 1){
      project.addClass("error");
      project_info.addClass("info_error");
      end_info.addClass("info_error");
      return false;
    }
    //it's valid
    else{
      project.removeClass("error");
      project_info.removeClass("info_error");
      end_info.removeClass("info_error");
      return true;
    }
  }

  function validateEvent(){
    //it's NOT valid
    if(des_event.val().length < 1){
      des_event.addClass("error");
      event_info.addClass("info_error");
      end_info.addClass("info_error");
      return false;
    }
    //it's valid
    else{
      des_event.removeClass("error");
      event_info.removeClass("info_error");
      return true;
    }
  }

  function validateHappened(){
    //it's NOT valid
    if(happened.val().length < 1){
      happened.addClass("error");
      happened_info.addClass("info_error");
      end_info.addClass("info_error");
      return false;
    }
    //it's valid
    else{
      happened.removeClass("error");
      happened_info.removeClass("info_error");
      return true;
    }
  }

  function validateAbout(){
    //it's NOT valid
    if(about.val().length < 1){
      about.addClass("error");
      about_info.addClass("info_error");
      end_info.addClass("info_error");
      return false;
    }
    //it's valid
    else{
      about.removeClass("error");
      about_info.removeClass("info_error");

      return true;
    }
  }

  function validateOrganisation(){
    //it's NOT valid
    if(organisation.val().length < 1){
      organisation.addClass("error");
      organisation_info.addClass("info_error");
      end_info.addClass("info_error");
      return false;
    }
    //it's valid
    else{
      organisation.removeClass("error");
      organisation_info.removeClass("info_error");
      return true;
    }
  }

  function validateRegion(){
    //it's NOT valid
    if(region.val().length < 1){
      region.addClass("error");
      region_info.addClass("info_error");
      end_info.addClass("info_error");
      return false;
    }
    //it's valid
    else{
      region.removeClass("error");
      region_info.removeClass("info_error");
      return true;
    }
  }

  function validateLiferules(){

    if (rules.attr("value") == "Yes" & liferules.val().length < 1) {
      liferules.addClass("error");
      rules_info.addClass("info_error");
      end_info.addClass("info_error");
      return false;
    }else{
      liferules.removeClass("error");
      rules_info.removeClass("info_error");
      return true;
    }
  });
}

这是我选择无线电是时需要使用该字段的功能：

function validateLiferules(){
  if (rules.attr("value") == "Yes" & liferules.val().length < 1) {
    liferules.addClass("error");
    rules_info.addClass("info_error");
    end_info.addClass("info_error");
    return false;
  }else{
    liferules.removeClass("error");
    rules_info.removeClass("info_error");
    return true;
  }
}

但是只要我把它放入其中就会打破整个表单验证。

复选框的HTML

<li><label for="rules"><i>* </i>Potential Breach of Life Saving Rules? (Not Applicable to Airports):</label></li>
                <li>
                    <input type="radio" name="rules" class="rules" value="Yes" ><span>Yes</span>

Answer 1

您应该使用表单提交处理程序的第一个参数调用event.preventDefault()。

form.submit(function(event) {
  if(isCorrect() === false) { // dummy function
    event.preventDefault() // This cancel form submit
  }
});

Answer 2

如果我理解正确，你有一个包含“规则”类的复选框。

然后你的验证功能应该是：

function validateLiferules(){
        // use rules.is(":checked") to check if the check box is checked
        if (rules.is(":checked") && liferules.val().length < 1) {
            liferules.addClass("error");
            rules_info.addClass("info_error");
            end_info.addClass("info_error");
            return false;
        }else{
            liferules.removeClass("error");
            rules_info.removeClass("info_error");
            return true;
        }
}

此外，你应该使用逻辑＆amp;＆amp;运算符而不是按位＆amp;运营商不是吗？
