Is there a way in Eclipse to change the ECMAScript compliance level?
提问by Sebastian Zartner
In Eclipse 4.5 (Mars) with installed JavaScript Development Tools (JSDT), the default compliance level for ECMAScript is set to ECMAScript 3, which is already very outdated. And the related drop down list to change the compliance level is deactivated, so it's not possible to change the option. Is there a way to change those settings to a newer standard like ECMAScript 5or ECMAScript 2015?
在安装了JavaScript 开发工具 (JSDT) 的Eclipse 4.5 (Mars) 中，ECMAScript 的默认合规性级别设置为ECMAScript 3，这已经非常过时了。并且用于更改合规性级别的相关下拉列表已停用，因此无法更改该选项。有没有办法将这些设置更改为更新的标准，例如ECMAScript 5或ECMAScript 2015？

There is no way to use a newer compliance level directly in JSDT, but with a plugin called tern-javayou can use ES5or ES2015(named before ES6).
没有办法直接在 JSDT 中使用更新的合规性级别，但是tern-java可以使用名为ES5or ES2015（之前命名为ES6）的插件。
I added this plugin via the installation of angular-eclipse. You can find this plugin on Eclipse Marketplace.
我通过安装 angular-eclipse 添加了这个插件。您可以在 Eclipse Marketplace 上找到此插件。

Eclipse 4.6 (Neon) added support for ECMAScript 2015 syntax and removed the ECMAScript compliance leveloption from the Preferencesdialog.
Eclipse 4.6 (Neon) 添加了对 ECMAScript 2015 语法的支持，并从首选项对话框中删除了ECMAScript 合规级别选项。
