javascript - angular 中的 ng-init 不起作用

Question

我是 angularjs 的新手。尝试使用它来构建简单的应用程序，我在 Controller 中定义了一个名为 cuurent 的变量，现在我想像下面这样设置输入字段的值:

  <div class="form-group">
        <input type="text" class="form-control" name="UserName" ng-model="management.regData.name" placeholder="UserName" ng-init="management.regData.name = '{{current.FullName}}'"  required>
        <p class="help-block" ng-show="(!editForm.UserName.$pristine && editForm.UserName.$error.required) || (editForm.$submitted && editForm.UserName.$error.required) ">this field is required</P>
          <p class="help-block" ng-show="regUser.usernameMsg && !editForm.UserName.$error.required && editForm.UserName.$valid">{{ regUser.usernameMsg }}</p>
          <ul ng-show="(!editForm.UserName.$pristine && editForm.UserName.$error.pattern) || (!editForm.UserName.$pristine && editForm.UserName.$error.minlength) || (!editForm.UserName.$pristine && editForm.UserName.$error.maxlength)" class="help-block">
            <li>Must not contain any special characters or spaces</li>
            <li>Must be at least 3 characters but no more than 25</li>
          </ul>
        </div>   

问题是 ng-init="management.regData.name = '{{current.FullName}}'"不起作用。有什么建议 ？

Answer 1

去掉大括号，直接加上

ng-init="management.regData.name = current.FullName"

演示

angular.module("app",[])
.controller("ctrl",function($scope){
$scope.management={"regData":{"name":""}}
$scope.current = {"FullName":"sample"}
})

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="app" ng-controller="ctrl">
 <input type="text" class="form-control" name="UserName" ng-model="management.regData.name" placeholder="UserName" ng-init="management.regData.name = current.FullName"  required>
</div>
