javascript - js这一坨代码有没有办法简化下，看着挺尴尬的

问题描述

问 题

$scope.ezzh_qsw_lines = Math.ceil($scope.ezzh_qsw.length / $scope.cols);
                $scope.ezzh_zsw_lines = Math.ceil($scope.ezzh_zsw.length / $scope.cols);
                $scope.ezzh_hsw_lines = Math.ceil($scope.ezzh_hsw.length / $scope.cols);
                $scope.bsdw_qsw_lines = Math.ceil($scope.bsdw_qsw.length / $scope.cols);
                $scope.bsdw_zsw_lines = Math.ceil($scope.bsdw_zsw.length / $scope.cols);
                $scope.bsdw_hsw_lines = Math.ceil($scope.bsdw_hsw.length / $scope.cols);
                $scope.bgdw_qsw_lines = Math.ceil($scope.bgdw_qsw.length / $scope.cols);
                $scope.bgdw_zsw_lines = Math.ceil($scope.bgdw_zsw.length / $scope.cols);
                $scope.bgdw_hsw_lines = Math.ceil($scope.bgdw_hsw.length / $scope.cols);
                $scope.sgdw_qsw_lines = Math.ceil($scope.sgdw_qsw.length / $scope.cols);
                $scope.sgdw_zsw_lines = Math.ceil($scope.sgdw_zsw.length / $scope.cols);
                $scope.sgdw_hsw_lines = Math.ceil($scope.sgdw_hsw.length / $scope.cols);
                $scope.bghs_qsw_lines = Math.ceil($scope.bghs_qsw.length / $scope.cols);
                $scope.bghs_zsw_lines = Math.ceil($scope.bghs_zsw.length / $scope.cols);
                $scope.bghs_hsw_lines = Math.ceil($scope.bghs_hsw.length / $scope.cols);
                $scope.sghs_qsw_lines = Math.ceil($scope.sghs_qsw.length / $scope.cols);
                $scope.sghs_zsw_lines = Math.ceil($scope.sghs_zsw.length / $scope.cols);
                $scope.sghs_hsw_lines = Math.ceil($scope.sghs_hsw.length / $scope.cols);

解决方案

思路大概是这样子：

const cols = $scope.cols

let list = ['ezzh_zsw', 'ezzh_hsw'] // 这里的数组换成自己需要的
list.map(function (key) {
    $scope[key+'_lines'] = Math.ceil($scope[key].length / cols);
})
