javascript - Angular ngModelOptions allowInvalid无法正常工作

Question

我有这样的代码，在这里我设置选项{allowInvalid: true}

<input type="number" name="userName"
         ng-model="user.name"
         ng-model-options="{ allowInvalid: true }"
         ng-blur="test(user)"/>

当我将非数字值输入非数字时，例如: abc，
为什么 user.name仍然更改为 undefined？
我期望模型 user.name应该是 'abc'。

我正在使用 Angular v1.3.16

在link之后，您不能将allowInvalid与type="number"属性一起使用。

Issues with HTML5 constraint validation

In browsers that follow the HTML5 specification, input[number] does not work as expected with ngModelOptions.allowInvalid. If a non-number is entered in the input, the browser will report the value as an empty string, which means the view / model values in ngModel and subsequently the scope value will also be an empty string.
