jquery - 根据特定条件突出显示 UI 表格行

Question

我在 UI 中显示了一个动态填充的表格，其中包含少量记录，其中保存了用户输入的 CSV 文件的数据。

通过 UI 删除一些记录并选择提交，如下 submit函数与 Controller 交互并返回 List<Object> 。这将替换现有的表。

我现在正在尝试突出显示具有成功状态的行。但徒劳无功。

有人可以指导我缺少什么吗？

// CONTROLLER UPLOAD FILE
uploadApp.controller('uploadFileController', [
    '$scope',
    '$rootScope',
    '$http',
    '$window',
    function($scope, $rootScope, $http, $window) {
        $scope.uploadResult = "";
        $scope.doUploadFile = function() {
            var file = $scope.uploadedFile;
            var url = "/uploadfile";

            var data = new FormData();
            data.append('uploadfile', file);

            var config = {
                transformRequest: angular.identity,
                headers: {
                    'Content-Type': undefined
                }
            }

            $http.post(url, data, config).then(
                function(response) {
                    $rootScope.policyData= response.data;
                });
        };

        $scope.deletRecord = function(RoleID) {
            var index = -1;
            var policyArray = eval($scope.policyData);
            for (var i = 0; i < policyArray.length; i++) {
                if (policyArray[i].RoleID === RoleID) {
                    index = i;
                    break;
                }
            }
            if (index === -1) {
                alert("Something gone wrong");
            }
            $scope.policyData.splice(index, 1);
            console.log(eval($scope.policyData));
        }

        $scope.submit = function(policyData) {
            $http({
                'url': '/updateOverride',
                'method': 'POST',
                'headers': {
                    'Content-Type': 'application/json'
                },
                'data': $scope.policyData
            }).then(function(response) {
                $scope.policyData = response.data;
                console.log(response);
                console.log($scope.policyData);
                for (var i = 0; i < response.data.length; i++) {
                    $("tr:contains(Success)").addClass("highlightRow");
                }

                $("#alert_success").show()
                $window.scrollTo(0, 0);
            })
        };
    }
]);

Answer 1

1. 您循环访问数据，但选择器是相同的，因此您可以设置一次。
2. 作为最佳实践，不要混合使用 jQuery 和 Angular - 您不知道 View (html) 何时会更改，因此您的代码无论如何都无法工作。

执行此操作的 Angular 方法是使用 ng-class行上的指令:

angular.module('app', []).controller('ctrl', function($scope) {
  $scope.items = [
    {
      name: 'item1',
      status: 'success'
    },
    {
      name: 'item2',
      status: 'fail'
    },
    {
      name: 'item3',
      status: 'success'
    },
  ];
});

.highlightRow {
  background: green;
}

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="app" ng-controller="ctrl">
  <table>
    <tr ng-repeat="item in items" ng-class="{highlightRow: item.status === 'success'}">
      <td ng-bind="item.name"></td>
      <td ng-bind="item.status"></td>
    </tr>
  </table>
</div>

在您的代码中，您需要将 ng-class 指令添加到 tr 中。像这样的东西:

<tr ng-class="{highlightRow: row.Note === 'success'}" st-select-row="row" st-select-mode="multiple" ng-repeat="row in display_records" id="{{row.PolicyNumber}}">
