angularjs - 使用 Angular ng-repeat 生成随机颜色

Question

如何在 ng-repeat 中生成随机颜色。我尝试了以下方式，但没有用。

我收到错误消息:

Error: [$rootScope:infdig] 10 $digest() iterations reached. Aborting!

Controller

$scope.getRandomColor = function(){
        return {
            borderLeft: '2px solid # '+Math.floor((Math.random()*6)+1)
        }       
    };

查看

<div ng-repeat="customer in customerData" class="col-sm-3">
    <div class="contact-box" ng-style="getRandomColor()">
    </div>
</div>

这是一个有效的 JSFiddle :

HTML:

<div ng-app="myApp" ng-controller="dummy">
    <div ng-repeat="customer in customerData" class="col-sm-3">
        <div class="contact-box" ng-style="customer.color">&nbsp; {{customer.name}} got: {{customer.color}}</div>
    </div>
</div>

JS:

angular.module('myApp', ['ngSanitize'])
    .controller('dummy', ['$scope', function ($scope) {

    var getRandomColor = function () {
        return {
            borderLeft: '2px solid #' + Math.floor(Math.random()*16777215).toString(16)
        }
    };

    $scope.customerData = [{
        name: "Mike",
        color: getRandomColor()
    }, {
        name: "Tom",
        color: getRandomColor()
    }];

}]);
