我目前正在学习 AngularJS 并正在构建一个地址簿。我有一个编辑按钮，第一次可以正常工作，但下一次就不行了。它只向我显示这个我不明白的错误。
TypeError: l is not a function
at angular.js:12234
at f (angular.js:22824)
at k.$eval (angular.js:14287)
at k.$apply (angular.js:14385)
at HTMLButtonElement.<anonymous> (angular.js:22829)
at HTMLButtonElement.dispatch (jquery-3.1.1.min.js:3)
at HTMLButtonElement.q.handle (jquery-3.1.1.min.js:3)
(anonymous) @ angular.js:11496
这是我的最小代码。

$scope.addressBook = [

angular.module("MyApp",[])
.controller("studentContoller",studentContoller);
</script>
</body>
</html>所以我有两个问题，我做错了什么？以及如何调试它。
提前致谢，
最佳答案
您正在将 JSON.parse 结果设置为与函数相同的名称。这就是为什么第二次就不起作用了。您必须使用不同的名称。
$scope.edit = function(item){
item.isEditing = true;
$scope.edit_test = JSON.parse(JSON.stringify(item)); // dirty deep copy
}
关于javascript - AngularJS 编辑按钮只能工作一次，然后出现 TypeError : l is not a function，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/41857912/
