在Eclipse中安装JSHint插件

离线安装

1、下载插件包 http://download.eclipsesource.com/~rsternberg/jshint-eclipse-0.9.8.20130728-0004-b94b446.zip

2、解压缩后是一个jshint-eclipse-0.9.8.20130728-0004-b94b446文件夹，拷贝至一个web容器中，可以敲地址访问的

例如：http://127.0.0.1/xx/jshint-eclipse-0.9.8.20130728-0004-b94b446 xx是项目名称，

3、在Eclipse主菜单，点击: Help > Install New Software…

输入上面的URL，然后选择 JSHint Eclipse Integration

不要急着点Next，当前界面最下一行的复选框勾去掉（Contact all update sites during install to find required software）
后面的安装过程很简单，往下按确定就可以了

在线安装或如何配置？

请参照这里 http://www.cnblogs.com/lhb25/archive/2012/04/05/javascript-validation-with-jshint-eclipse.html

按道理可以直接使用了，但似乎还是不行...

需修改配置，步骤如下：

1、下载官方的jshint.js https://raw.github.com/jshint/jshint/master/dist/jshint.js （可选操作）

Window > Preferences > JSHint   点击JSHint 选择Provide a custom JSHint library file  然后选择刚才下载的jshint.js文件

2、配置验证的选项 Window > Preferences > JSHint > Configuration
