Question

当我在输入数字字段中输入十进制数字时，我想显示一些错误消息。所有其他错误都在抛出，也想这样做。请查看我的代码

  <form name = "myForm">
     <md-input-container md-is-error = "myForm.quantityUpdateCtrl.$invalid">
        <label>Quantity To Be Updated</label>
           <input type = "number"
             name = "quantityUpdateCtrl"
             ng-model = "quantityToBeChange"
             ng-min = 1
             ng-step="0"
             ng-init = "quantityToBeChange=1"
             ng-max = boxedItem.item_status.quantity_accepted
             required>
     <div role = "alert" ng-messages = "myForm.quantityUpdateCtrl.$error">
         <div ng-message = "required">Quantity should not be empty</div>
         <div ng-message = "min">Entered quantity should be greater than 0</div>
         <div ng-message = "max">Entered quantity cannot be greater than Item quantity</div>
         <div ng-message = "step">Entered Integer</div>
     </div>
   </md-input-container>

试过这个，不起作用。

<div ng-message = "step">Entered Integer</div>

请帮助我解决。

NOTE: I don't want to call a function and validate and then return.

得到答案。

在输入标签中添加了ng-pattern="/^[0-9]{1,}$/"。

检查<div ng-message = "pattern">Please Enter An Integer</div>

angularjs中的ngStep验证
