先前的有一点bug,如此写后更简单

js代码

    //已选择的品种,不能再次选择       var selectList =[];    $scope.selectGoods=function(item,index){    if(selectList.length>0){    var flag=0;    for(var i=0;i<selectList.length;i++){    if(selectList[i]==item&&item!=undefined){        $scope.result = {};                $scope.result.title = "提示消息";                $scope.result.msg = "亲,请不要选择重复商品!";                $scope.popup();        //对当前的所选择的进行清空        $scope.applyList.purchaseLists[this.$index]={};        flag=1;        }        }    }else if(flag==1){    selectList[index]=null;    }else{    selectList[index]=item;    }    };      //添加列表    $scope.addCols = function(){        $scope.applyList.purchaseLists.push({});    };  //删除列表    $scope.removeRow = function(index,item){        $scope.applyList.purchaseLists.splice(index, 1);    selectList.splice(index,1);    };      //弹窗开始    $scope.popup = function() {        $modal.open({            templateUrl : 'tpls/common/alertMessage.html',//弹窗公共页面            controller :ModalInstanceCtrl2,            resolve : {                requestResults : function() {                    return $scope.result;                }            }        });     };    var ModalInstanceCtrl2 = function($scope, $modalInstance, requestResults) {        $scope.results = requestResults;        // 确认按钮(close()可以带参数)        $scope.ok = function() {            $modalInstance.close();        };    };    //弹窗结束
html部分代码:

<tr name="form" ng-repeat="item in applyList.purchaseLists">    <td>        <select ng-model="item.goods" name="goods" ng-options="product.goodsName for product in products" ng-required="true" ng-change="selectGoods(item.goods,$index)">            <option value="">请选择品种</option>        </select>    </td>
