$范围VS在AngularJS VAR [英] $scope vs var in AngularJS

问题描述

我一直在使用var和$ scope.varname和AngularJS都做工精细。我在想，如果有两个功能，什么最好的做法是在使用哪一个？

I've been using var and $scope.varname and both work fine in AngularJS. I was wondering if there was a difference between the two functionally, and what best practice was in which one to use?

推荐答案

是的！ $范围变量绑定到视图，为 VAR 不和是本地的它在声明的功能！

Yes! $scope variables bind to the view where as var does not and is local to the function it was declared in!

var x = 3;
$scope.y = 3;

{{x}} - undefined
{{y}} - 3
