Question

我有一个相当简单的验证功能，只检查输入是否为空。我在六种不同的形式中使用它，除了一个特定的输入id="driver_first_name"之外，它似乎在任何地方都有效。无法弄清楚它为何失败。

如果我将所有字段留空，我会在所有字段中出现错误，并且除了driver_first_name之外，我尝试的任何组合通常都是正确的。如果我填写除driver_first_name之外的所有内容，则表单提交无论如何。

对此处可能发生的事情有任何见解？

谢谢！

我的验证功能是：

    function validateForm(form, fields) { //add exit anbimation and reset the container state
    $(".form-input-error").remove();
    var result=false;
    $.each( fields.rules, function( key, value ) {
        if(!$("#"+key+"").val()){
            $("#"+key+"").addClass("form-error");
            $( "<div class='form-input-error'>"+value.message+"</div>" ).insertBefore("#"+key+"");
             result = false;
            //console.log(this.val());
        }
        else{
            $("#"+key+"").removeClass("form-error");
             result = true;
        }   
});
     return result;
}

我在提交触发器上调用我的验证，对于不应该为空的字段通常是这样的：

$(".app-canvas").on('click', ".submitNewDriver", function () {//list all drivers trigger
            var checkInputs = {
        rules: {
            driver_first_name: {
                message: "First Name is Required"
            },
            driver_last_name: {
                message: "Last Name is Required"
            },
            driver_address_street: {
                message: "street is Required"
            }
        }
    };  
    if(validateForm($("#addDriverForm"),checkInputs) == true){
    console.log("form submit");
        addNewDriver();
    }
    else{
        console.log("form errors");
    }
    });

Answer 1

您的验证逻辑有点混乱。这就是发生的事情：

#driver_first_name被视为无效...... result已设置为false
#driver_last_name已经过验证有效... result已设置为true
#driver_address_street已经过验证有效... result已设置为true

毕竟代码认为表单有效。如果最后一个字段被验证为无效，则您只能阻止提交表单。

更改逻辑以假设表单从一开始就有效。如果任何字段无效，则将其设置为false。

我也没有在代码中看到任何实际阻止表单提交的内容，所以我还添加了e.preventDefault()

＆＃13;

function validateForm(form, fields) { //add exit anbimation and reset the container state
  $(".form-input-error").remove();
  var result = true;
  $.each(fields.rules, function(key, value) {
    if (!$("#" + key + "").val()) {
      $("#" + key + "").addClass("form-error");
      $("<div class='form-input-error'>" + value.message + "</div>").insertBefore("#" + key + "");
      result = false;
      //console.log(this.val());
    } else {
      $("#" + key + "").removeClass("form-error");
    }
  });
  return result;
}

$(".app-canvas").on('click', ".submitNewDriver", function(e) { //list all drivers trigger
  var checkInputs = {
    rules: {
      driver_first_name: {
        message: "First Name is Required"
      },
      driver_last_name: {
        message: "Last Name is Required"
      },
      driver_address_street: {
        message: "street is Required"
      }
    }
  };
  if (validateForm($("#addDriverForm"), checkInputs) == true) {
    console.log("form submit");
  } else {
    e.preventDefault();
    console.log("form errors");
  }   
});
