$scope.selected=0;
<select class="form-control lls-input-lg" id="cooperationPlatform" ng-model="selected">
<option value="0">全部</option>
<option ng-repeat="o in keyArr"
value="{{o.id}}">
{{o.prodName}}
</option>
</select>
出来是这样
而且默认也没有选中
还有一点就是如果我用ng-options 出来是这样子的
value很奇怪，我的数据里面，id:1，这样的，还多了个label
求解答！！

需使用ng-value进行值绑定哈，另外建议把默认选项也添加到数组中，统一进行 ng-repeat 循环就好了。同时建议命名规范一下哈如：user in users 或 produce in produces 这种形式。
ng-options示例
<select class="form-control lls-input-lg" id="cooperationPlatform"
ng-options="o.prodName for o in keyArr"
ng-model="selected">
</select>
----------
$scope.selected=$scope.keyArr[1];ng-value示例
