没有包含<form>的AngularJS <input>validation
是否有可能在Angular中validation一个单独的<input>类似的方式来validation表单？ 我正在考虑这样的事情：
<div class="form-group"> <input name="myInput" type="text" class="form-control" ng-model="bindTo" ng-maxlength="5"> <span class="error" ng-show="myInput.$error.maxlength">Too long!</span> </div>
上面的例子不起作用。 用<form> ng-show="myForm.myInput.$error.maxlength"用ng-show="myForm.myInput.$error.maxlength"replaceng-show 。
有没有可能做到这一点，而不使用<form> ？
您可以使用ng-form angular指令（ 请参阅此处的文档 ）对任何内容进行分组，即使在html表单之外。 然后，你可以利用angular度FormController。
<div class="form-group" ng-form name="myForm"> <input name="myInput" type="text" class="form-control" ng-model="bindTo" ng-maxlength="5"> <span class="error" ng-show="myForm.myInput.$error.maxlength">Too long!</span> </div>
例
build立在西尔维奥卢卡斯的答案，如果你迭代循环，需要能够插入表单名称和有效状态：
<div name="{{propertyName}}" ng-form="" class="property-edit-view" ng-class="{ 'has-error': {{propertyName}}.editBox.$invalid, 'has-success': {{propertyName}}.editBox.$valid && {{propertyName}}.editBox.$dirty && propertyValue.length !== 0 }" ng-switch="schema.type"> <input name="editBox" ng-switch-when="int" type="number" ng-model="propertyValue" ng-pattern="/^[0-9]+$/" class="form-control"> <input name="editBox" ng-switch-default="" type="text" ng-model="propertyValue" class="form-control"> <span class="property-type" ng-bind="schema.type"></span> </div>
