Jquery验证依赖字段

Question

Huy Guys,

我正在尝试使用jQuery验证插件,并指定只有当其他3个字段为空(未填充)时才需要一个字段.

问题是该规则正在运行,但即使我在其上键入值,它仍然需要该字段.

谢谢.

这是我的代码:

$("#ProspectDtlFrm").validate({
 rules: {

  prsptEmail: {
   required: function(element) { return ( $("#prsptHomePhone").val() == '' && $("#prsptBusinessPhone").val() == '' && $("#prsptMobilePhone").val() =='') }                                         
   }    
 },
 messages: {
      prsptEmail: "Please enter your first name"
 }
}); 

Answer 1

你可以使用depends:

$('#ProspectDtlFrm').validate({ 
    rules: {
        prsptEmail: {
            required: {
                depends: function(element) {
                    return ($('#prsptHomePhone').val() == '' && 
                            $('#prsptBusinessPhone').val() == '' && 
                            $('#prsptMobilePhone').val() == '');
                }
            }
        }    
    }, 
    messages: { 
        prsptEmail: 'Please enter your first name'
    } 
});

该depends条款仍受支持.这是从1.11.0pre版本:

normalizeRules: function(rules, element) {
  // handle dependency check
  $.each(rules, function(prop, val) {
    // ignore rule when param is explicitly false, eg. required:false
    if (val === false) {
      delete rules[prop];
      return;
    }
    if (val.param || val.depends) {
      var keepRule = true;
      switch (typeof val.depends) {
        case "string":
          keepRule = !!$(val.depends, element.form).length;
          break;
        case "function":
          keepRule = val.depends.call(element, element);
          break;
      }
      if (keepRule) {
        rules[prop] = val.param !== undefined ? val.param : true;
      } else {
        delete rules[prop];
      }
    }
  });

如您所见,您可以在"字符串"和"功能"之间进行选择.所以你可以使用:

rules: {
  input_name_here: {
    required: {
      depends: function(element) {
        return $("#thickBoxId:checked").length;
        //or whatever you need to check
      }
    }
  }
}

要么

rules:{
  input_name_here:{
    required: '#tickBoxId:checked'
  }
}

如果您只需要测试是否存在已检查的内容.

'依赖'似乎不再受支持,并且,他们的文档不是最新的.

因此,如果选中"是"复选框,则验证另一个字段:

rules:{
    'name value of area you want to validate':{
        required: '#tickBoxId:checked'
    }
}

方法就是depends它的作品。

    rules: {
        prsptEmail: {
            required: {
                depends: function(element){
                    if ($('#id-user').val() == '') {
                        return true;
                    } else {
                        return false;
                    }
                }
            }
        },
    },
    messages: {
        prsptEmail : {
            required : "please signIn!",
        }
    },
