Question

我收到3个不同的错误：预期的标识符，意外的令牌，未知的类：＆＃39;得分＆＃39;。这些错误在第57-69行。

此代码的要点是检查是否选中了核对表，如果是，则将1添加到分数。它根据分数将输出文本更改为不同的字符串。

Answer 1

您的大括号$document.on('scroll', function() { // do your things like logging the Y-axis console.log($window.scrollY); // or pass this to the scope $scope.$apply(function() { $scope.pixelsScrolled = $window.scrollY; }) });位于错误的位置。该函数在}之前结束。

if

if和else语句出错
