angular选取select下拉框中某项option中value的值

<select ng-model="content.lotteryType" ng-change="change(content.lotteryType)">
	<option value="spinWin">{{'lottery.type.spinWin'|translate}}</option>
	<option value="sudoku">九宫格</option>
</select>

2.js

            $scope.change = function (type) {
                $scope.myType = type;
            }

3.在同一个html中使用获取到的值myType 即可.

<a ng-click="myType=='sudoku'?currentStep = currentStep - 2:currentStep = currentStep - 1" ng-show="currentStep > 0">前一步</a>
