Angularjs 错误：[$rootScope:infdig]已达到10$digest（）次迭代。放弃错误的事情

获取此错误：

不知道我为什么和在哪里包括任何与$location有关的内容，因为它给了我这个错误。知道如何调试这个问题吗

有时观察函数会产生奇怪的行为，导致出现这种情况。我不熟悉querySelectorAll，但可能是它返回的内容太频繁了。如果可以观察变量而不是函数，那么问题就可以解决了

$scope.$watch(function(){return document.querySelectorAll("span.joggleEmail")},function(newValue, oldValue){
            var emails = document.querySelectorAll("span.joggleEmail")

            angular.forEach(emails, function(span){
                // unbind the click, this is important for `mailto:`
                angular.element(span).unbind("click");

                angular.element(span).bind("click", function(){
                    console.log("Searching...");
                    $scope.$broadcast("searchServer", this.innerHTML);
                });
            })
        }, true)
