如何设置 ng-model 的默认值？

Question

我这里有一个用于发布简单数据的表单，我想为我的输入设置一个默认字符串值，但为什么它没有出现，我试过 ng-value 但它也不起作用。如何为我的 ng-model 设置默认字符串？

<form name="regForm" ng-submit="register.regUser(regData);">

<input type="text" ng-model="register.regData.branch_name" name="branch_name" value="This is a string">   
<button type="submit">Submit</button>

</form>

Answer 1

使用 ng-init 指令设置默认值，如下所示：

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="">
<form name="regForm" ng-submit="register.regUser(regData);">

<input type="text" ng-model="register.regData.branch_name" name="branch_name"  ng-init="register.regData.branch_name='This is a string'">   
<button type="submit">Submit</button>

</form>
</div>
