JSLint检测Javascript语法规范

前端javascript代码编写中，有一个不错的工具叫JSLint，可以检查代码规范化，压缩JS，CSS等，但是他的语法规范检查个人觉得太“苛刻”了，会提示各种各样的问题修改建议，有时候提示的信息我们看的莫名其妙，这里，先转载一下携程UED的一个技术文章（原文链接http://ued.ctrip.com/blog/?p=2733），看看JSLint的错误提示都是什么意思：

“Missing semicolon.” : “缺少分号.”,“Use the function form of \”use strict\”.” : “使用标准化定义function.”,“Unexpected space after ‘-’.” : “在’-'后面不应出现空格.”,“Expected a JSON value.” : “请传入一个json的值.”,“Mixed spaces and tabs.”: “空格和TAB重复.”,“Unsafe character.” : “不安全的字符.”,“Line too long.”: “本行中的字符超过设定的最大长度.”,“Trailing whitespace.”: “本行末尾有过多无用空格.”,“Script URL.” : “脚本URL.”,“Unexpected {a} in ‘{b}’.” : “在 ‘{b}’ 中不该出现 {a}.”,“Unexpected ‘{a}’.” : “不该在此出现’{a}’.”,“Strings must use doublequote.” : “字符串需要用双引号”,“Unnecessary escapement.” : “不需要转义”,“Control character in string: {a}.” : “在字符串中出现了Control的字符”,“Avoid \\’.” : “避免 \\”,“Avoid \\v.” : “避免 \\v”,“Avoid \\x-.” : “避免 \\x-”,“Bad escapement.” : “错误的转义字符”,“Bad number ‘{a}’.” : “错误的数字 ‘{a}’”,“Missing space after ‘{a}’.” : “在’{a}’之后缺少空格”,“Don’t use extra leading zeros ‘{a}’.” : “不要再’{a}’的前面用多余的0″,“Avoid 0x-. ‘{a}’.” : “避免使用 0x-. ‘{a}’.”,“A trailing decimal point can be confused with a dot ‘{a}’.” : “在’{a}’中使用点尾随小数点”,“Unexpected comment.” : “不该在此处出现注释”,“Unescaped ‘{a}’.” : “没有转义 ‘{a}’”,“Unexpected control character in regular expression.” : “在正则表达式中出现了control字符”,“Unexpected escaped character ‘{a}’ in regular expression.” : “在正则表达式中出现了没有转义的字符 ‘{a}’”,“Expected ‘{a}’ and instead saw ‘{b}’.” : “应该用 ‘{a}’代替’{b}’”,“Spaces are hard to count.
