角度表单验证无法正常工作

Question

我已经在离子角度和应用验证上创建了一个表单.Validations无法正常工作.即使所有字段都是空的点击提交按钮它调用控制器功能.请帮我解决这个问题.

HTML代码

<ion-pane>
<ion-header-bar class="bar-stable">
<h1 class="title">Register</h1>
</ion-header-bar>
<ion-content >
<form name="register"  ng-submit="submitDetails(user)" novalidate=""> 
    <div class="list">
        <label class="item item-input item-floating-label" style="position:relative;">
            <span class="input-label">First Name</span>
            <input type="text" placeholder="First Name" ng-model="user.firstName" ng-required="true">
            <p ng-show="user.firstName.$invalid && !user.firstName.$pristine" class="help-block">You name is required.</p>
        </label>
        <label class="item item-input item-floating-label">
            <span class="input-label">Email</span>
            <input type="email" placeholder="Email" ng-model="user.email" ng-required="true">
            <p ng-show="user.email.$invalid && !user.email.$pristine" class="help-block">Enter a valid email</p>
        </label>
        <label class="item item-input item-floating-label">
            <span class="input-label" >Phone no</span>
            <input type="number" placeholder="Phone No" ng-model="user.phone" ng-minlength="10" ng-maxlength="10" ng-required="true">
            <span class="help-block" ng-show="user.phone.$error.required || user.phone.$error.number">Valid phone number is required</span>
            <span class="help-block" ng-show="((user.phone.$error.minlength || user.phone.$error.maxlength) && user.phone.$dirty) ">phone number should be 10 digits</span>
        </label>
        <input type="submit" class="button button-royal"  value="register">
    </div>
</form>
</ion-content>
</ion-pane>

控制器代码

chatApp.controller('RegisterCntrl', function($scope, $stateParams) {
    $scope.user={};
    $scope.submitDetails=function(user){
        alert("user"+user.firstName);
    };
});

这应该工作

<form name="register_form"  ng-submit="submitDetails(user)" novalidate=""> 
    <div class="list">
        <label class="item item-input item-floating-label" style="position:relative;">
            <span class="input-label">First Name</span>
            <input type="text" name="user_first_name" placeholder="First Name" ng-model="user.firstName" ng-required="true">
            <p ng-show="register_form.user_first_name.$invalid && !register_form.user_first_name.$pristine" class="help-block">You name is required.</p>
        </label>
        <!--omitted-->
        <input type="submit" class="button button-royal"  value="register">
    </div>
</form>

表格名称是register_form,

<form name="register_form"  ng-submit="submitDetails(user)" novalidate="">

输入名称是user_first_name,

<input type="text" name="user_first_name" placeholder="First Name" ng-model="user.firstName" ng-required="true">

因此验证必须通过这些字段

  <p ng-show="register_form.user_first_name.$invalid && !register_form.user_first_name.$pristine" class="help-block">You name is required.</p>

模型本身没有$invalid或$pristine属性,所以它没有意义

对于电话领域

<input type="number" name="user_phone" placeholder="Phone No" ng-model="user.phone" ng-minlength="10" ng-maxlength="10" ng-required="true">
<span class="help-block" ng-show="register_form.user_phone.$error.required || register_form.user_phone.$error.number">Valid phone number is required</span>
<span class="help-block" ng-show="((register_form.user_phone.$error.minlength || register_form.user_phone.$error.maxlength) && register_form.user_phone.$dirty) ">phone number should be 10 digits</span>
