我无法获得ng-if包含的输入值 这是html代码
<div ng-controller="Home">
<form ng-submit="startChat(visitor)" >
<div class="lkv_getting">
<div ng-if="formsetting.name == true">
<input required ng-class="lkv_name_class" ng-model="visitor.name" id="lkv_name" name="lkv_name" type="text" class="lkv_input" placeholder="Nhập họ tên" />
</div>
<textarea required maxlength="100" placeholder="Gõ tin nhắn!!" ng-model="visitor.msg" id="message_input" name="lkv_message_input"></textarea>
<button class="lkv_button" type="submit" id="lkv_start" title="Message">Bắt đầu</button>
</div>
</form>
</div>
和控制器
$scope.startChat = function (visitor) {
var user = visitor.name; // the value is undefine
var msg = visitor.msg; // but this one has value
};
任何人都可以帮助我吗?提前致谢

使用ng时 - 如果formsetting.name永远等于false,则DOM元素不会被渲染。这意味着您无法获得输入值,因为它们无法呈现给DOM。检查formsetting.name是否确实为true或在控制器中初始化为true,如果这对你有意义的话。如果formsetting.name可以更改值,则可能需要使用ng-show。使用ng-show将元素绘制到DOM但隐藏它们,以便您仍然可以访问它们。
