jQuery验证:动态更改规则

啊,验证插件,总是那么棘手:(

$("input[name='userAction']").change(function() {
    $('#signupFields').toggle();
    $('#loginFields').toggle();    
    if ($("input[name='userAction']:checked").val() === "login") {
        removeRules(signupRules);
        addRules(loginRules);
    } else {        
        removeRules(loginRules);
        addRules(signupRules);

    }
});

添加和删除函数如下所示:

function addRules(rulesObj){
    for (var item in rulesObj){
       $('#'+item).rules('add',rulesObj[item]);  
    } 
}

function removeRules(rulesObj){
    for (var item in rulesObj){
       $('#'+item).rules('remove');  
    } 
}

差不多了。有关工作示例,请参见此处: http://jsfiddle.net/ryleyb/wHpus/66/

编辑 形式 你打电话之后 validate

或者你可以使用 取决于

http://jqueryvalidation.org/category/plugin/ 搜索依赖项

示例:根据需要和电子邮件地址指定联系人元素,后者取决于通过电子邮件选中联系人复选框。

$(".selector").validate({
  rules: {
    contact: {
      required: true,
      email: {
        depends: function(element) {
          return $("#contactform_email:checked")
        }
      }
    }
  }
});

呼叫

$('#formid').removeData('validator')

这将删除表单的验证,然后使用新设置重新初始化它

一些例子:

1. 打印附加到的所有规则 #myField : console.log($('#myField').rules());

2. 删除不需要的规则: $('#myField').rules('remove', 'min');

3. 添加新规则: $('myField').rules('add', {min: 10});

remove 以及 add 刚好在…之后:

// Something happened. The minimum value should now be 100
$('#myField').rules('remove', 'min');
$('#myField').rules('add', {min: 100});

https://jqueryvalidation.org/category/plugin/#-rules()

现在有一个选项可以忽略基于选择器条件的字段,例如不可见或已禁用,这样您就不必更改规则集:

.validate({
  ignore: ":not(:visible),:disabled",
  ...

rules: {
    address: {
       required: {
                   depends: function(element) {
                     if (....){
                       return true;}
                     else{
                       return false;}
                   }
                 }
             }
       }

跟踪验证对象并直接删除/替换规则。在v1.13.0中为我工作

var validation = $('#form1').validate(); //Keep track of validation object

//Rule set 1
var validationRulesLogin = {
    headerEmail: {
        required: true,
        email: true
    },
    headerPassword: "required"
};
var validationMessagesLogin = {
    headerEmail: {
        required: "Please enter your email address.",
        email: "Not a valid email address."
    },
    headerPassword: "Please enter your password."
};

//Rule set 2
var validationRulesSignup = {
    signupEmail: {
        required: true,
        email: true
    },
    signupPassword: "required",
    signupPassword2: {
        equalTo: "#phBody_txtNewPassword"
    }
};
var validationMessagesSignup = {
    signupEmail: {
        required: "Please enter your email address.",
        email: "Not a valid email address."
    },
    signupPassword: "Please enter your password.",
    signupPassword2: "Passwords are not the same."
};

//Toggle rule sets
function validatingLoginForm(){
    validation.resetForm();
    validation.settings.rules = validationRulesLogin;
    validation.settings.messages = validationMessagesLogin;
}
function validationSignupForm(){
    validation.resetForm();
    validation.settings.rules = validationRulesSignup;
    validation.settings.messages = validationMessagesSignup;
}

$("input[name='userAction']").change(function() {

    var settings = $("#myForm").validate().settings;

      if ($("input[name='userAction']:checked" ).val() === "login") {
            $.extend(settings, {
              rules: loginRules
            });
    } else {
            $.extend(settings, {
              rules: signupRules
            });
    }


    $("#myForm").valid();

});

我有一个类似的问题,并通过在所有登录文本框中添加一个“requiredForLogin”类和在所有注册文本框中添加一个“requiredForSignUp”类来解决它。

然后使用jQuery的toggleClass和jQuery.validate的addClassRules根据按下的按钮打开和关闭规则。

function EnableAllValidation() {
    // remove the jquery validate error class from anything currently in error
    //  feels hackish, might be a better way to do this
    $(".error").not("label").removeClass("error");

    // remove any the 'disabled' validation classes, 
    //  and turn on all required validation classes 
    //  (so we can subsequently remove the ones not needed)
    $(".requiredForLoginDisabled").toggleClass("requiredForLoginDisabled requiredForLogin");
    $(".requiredForSignUpDisabled").toggleClass("requiredForSignUpDisabled requiredForSignUp");
}
function EnableLoginValidation() {
    // reenable all validations
    //  then disable the signUp validations
    EnableAllValidation();
    $(".requiredForSignUp").toggleClass("requiredForSignUpDisabled requiredForSignUp");
}
function EnableSignUpValidation() {
    // reenable all validations
    //  then disable the login validations
    EnableAllValidation();
    $(".requiredForLogin").toggleClass("requiredForLoginDisabled requiredForLogin");
}
$(document).ready(function () {
    $("input[value='login']").click(function () {
        EnableLoginValidation();
    });
    $("input[value='signup']").click(function () {
        EnableSignUpValidation();
    });

    $("#myForm").validate();
    jQuery.validator.addClassRules({
        requiredForSignUp: {
            required: true
        },
        requiredForLogin: {
            required: true
        }
    });

});

下面的代码运行得很好。。。

.validate({
  ignore: ":not(:visible),:disabled",
  ...
