angular JS 实现数组对象遍历赋值

    angular.forEach(vm.details, function (data, index, array) {
                    angular.forEach(data, function (value, key) {
                        if (value == "") {
                            vm.details[index][key] = null;
                        }
                    })
                });

angular.forEach(vm.geographyPipelineDetails,function(data, index, array){

angular.forEach(data,function(value, key){

if(value ==""){

vm.geographyPipelineDetails[index][key]=null;

}

})

});
