angularjs – 角度清除子表单数据和复位验证

前端之家收集整理的这篇文章主要介绍了angularjs – 角度清除子表单数据和复位验证前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。
我正在尝试创建子表单< divng-form =“vacancyForm”>与Angular.js

有一种类型的数据具有许多字段

>标题
>可用日期
>价格

所有的都需要验证。

一旦我提交了数据,我会做我需要的,但我想重置子窗体,所有的字段都不脏,窗体是有效的,因为在清除字段工作,但所有字段都无效,因为他们现在是脏的,但是空的标记为无效。

示例字段

<div class="control-group" ng-class="getErrorClasses(vacancyForm.headline)">
     <label class="control-label" for="headline">Headline</label>
     <div class="controls">
         <input type="text" class="input-xlarge" id="headline" name="headline" required ng-model="new_vacancy.headline">
         <span class="help-inline" ng-show="showError(vacancyForm.headline,'required')">This field is required</span>
      </div>
</div>

这里是提交时调用函数

$scope.addVacancy = function(){

        // save the submitted data
        $scope.school.vacancies.push($scope.new_vacancy);

        // now clear it out
        $scope.new_vacancy = {};
        $scope.new_vacancy.date = new Date();

        // this clears out all the fields and makes them all invalid 
        // as they are empty. how to reset the form???

    }
使用< form>标签并设置name属性,然后可以$ scope.formName。$ setPristine();其中formName是name属性。当值已更改时,元素不再原始。

http://docs.angularjs.org/api/ng.directive:form.FormController#$setPristine

更新
上面的答案只是1.2,但在1.3角引入了一个“触摸”输入的概念。现在当元素模糊时,角将标记为触摸的字段。与$ setPristine类似,您可以使用$ scope.formName。$ setUntouched()设置输入。

https://docs.angularjs.org/api/ng/type/form.FormController#$setUntouched

touch vs pristine:triggered表示字段已模糊,而pristine表示字段的值已修改。 Angular的文档注意到:“将表单设置为原始状态时,将表单控件恢复到未更改状态通常很有用。

编辑
这里是一个小提琴演示:https://jsfiddle.net/TheSharpieOne/a30kdtmo/

angular.module('myApp',[])
  .controller('myCtrl',myCtrl);

function myCtrl() {
  var vm = this;
  vm.reset = function() {
    vm.myForm.$setPristine();
    vm.myForm.$setUntouched();
    vm.email = vm.password = '';
  }
}
.ng-invalid.ng-touched {
  outline: 2px solid blue;
}
.ng-invalid.ng-dirty {
  outline: 2px solid red;
}
.ng-invalid.ng-dirty.ng-untouched {
  outline: 2px solid green;
}
form,form div {
  padding: 5px 10px;
}
h3,h4 {
  margin-bottom: 0;
}
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.5.0/angular.min.js"></script>
<div ng-app="myApp" ng-controller="myCtrl as ctrl">
  <form name="ctrl.myForm">
    <div>
      <label for="email">Email</label>
      <input name="myInput" type="email" ng-model="ctrl.email" id="email" required>

    <div>
      <label for="password">Password</label>
      <input name="myPassword" type="password" minlength="8" ng-model="ctrl.password" id="password" required>
    </div>
    <div>
      <button ng-click="ctrl.reset()" type="button">Reset</button>
    </div>
  </form>
  <div>
    <h4>Form Level</h4>
    <div>$dirty: {{ctrl.myForm.$dirty}}</div>
    <div>$pristine: {{ctrl.myForm.$pristine}}</div>
    <h4>Input Level</h4>
    <h5>Email Input</h5>
    <div>$dirty: {{ctrl.myForm.myInput.$dirty}}</div>
    <div>$pristine: {{ctrl.myForm.myInput.$pristine}}</div>
    <div>$touched: {{ctrl.myForm.myInput.$touched}}</div>
    <h5>Password Input</h5>
    <div>$dirty: {{ctrl.myForm.myPassword.$dirty}}</div>
    <div>$pristine: {{ctrl.myForm.myPassword.$pristine}}</div>
    <div>$touched: {{ctrl.myForm.myPassword.$touched}}</div>
  </div>
  <div>
    <h3>Color outlines for input</h3>
    <div title="The form loads this way,it can still be invalid since required fields are empty to start with">untouched,pristine: no outline</div>
    <div title="Such as in the middle of typing a valid email for the first time">invalid,untouched,dirty: green outline</div>
    <div title="blurred with invalid input">invalid,touched,dirty: red outline</div>
    <div title="focued and blurred without typing">invalid,touched: blue outline</div>
  </div>
</div>
