sim*_*ing 12 javascript angularjs angularjs-ng-init
我有一个简单的选择元素,我试图强制提供一个值来提交表单,我尝试了设置所需的属性以及使用ng-init来确保选择了一个值并且都失败了.
我ng-options用来创建一个具有ref属性的对象数组的值列表.然后我想ng-init用于将显示的值设置为数组中的第一个Object.ref.
<select name="refmarker" class="input-block-level form-width-adjust" ng-model="model.refmarker" ng-options="rm.ref for rm in refmarkers" ng-disabled="editable" ng-init="model.refmarker='refmarkers[0].ref'" required></select>
我没有运气就试过以下
ng-init="model.refmarker='refmarkers[0]'"
ng-init="model.refmarker='refmarkers[0].ref'"
ng-init="model.refmarker='rm.ref'"
该required属性也不起作用？角度选择元素是否错误或我做错了什么？

required仅适用于表单元素.
你想要的是ng-init ="model.refmarker = refmarkers [0]"
