AngularJS代码优化：打印奇数列表

"$scope.printSummary = function (oddNumbers) {\n var oddNumberList = [];\n oddNumberList = oddNumbers\n var oddNumber = "";\n angular.forEach(oddNumberList,function (item,index){\n if (index+1 == oddNumberList.length ){\n oddNumber +=item;\n }else {\n oddNumber += item+" " ;\n }\n })\n console.log(oddNumber); // 输出oddNumber字符串\n }\n" 代码有问题。在函数中，尽管oddNumber变量被声明了，但是它的值没有被返回或者输出。所以，代码只是将oddNumbers中的奇数拼接成一个字符串，但是没有对该字符串进行处理或者输出。正确的代码应该是：\n\n$scope.printSummary = function (oddNumbers) {\n var oddNumberList = [];\n oddNumberList = oddNumbers\n var oddNumber = "";\n angular.forEach(oddNumberList,function (item,index){\n if (index+1 == oddNumberList.length ){\n oddNumber +=item;\n }else {\n oddNumber += item+" " ;\n }\n })\n console.log(oddNumber); // 输出oddNumber字符串\n }
