JSLint Setting

Filter Code	Describe	Other
Adsafe	If Adsafe rules should be enforced	Whether to verify the third party JS Library Adsafe.
Bitwise	If bitwise operators should be allowed	If true, Shint disables the bitwise operator JavaScript allow bit arithmetic, but he does not have an integer, the bitwise operator converts the number of digits that participate in the operation into an integer, and then returns it after the operation. So they are less efficient than they are in other languages.
Browser	If the standard browser globals should be predefined	Whether a standard browser global variable should be predefined.
Caps	If Upper case HTML should is allowed	Whether to allow uppercase HTML tags.
Confusion	If types can be used inconsistently	Whether the variable uses the same type.
Continue	If the continuation statement should be tolerated	Whether to allow continuous declarations.
Css	If CSS workarounds should be tolerated	Whether to allow CSS fields.
Debug	IF Debugger statements should be allowed	Whether to allow debugger declarations.
Devel	If logging should be allowed (console, alert, etc.)	Whether to allow debugging JS.
Eqeqeq	If = = should be allowed	If true, JSLint will see if you are using either = = or!== in your code, instead of using = = and!=.

Filter Code	Describe	Other
Es5	If ES5 syntax should be allowed	Whether to allow ECMAScript 5 syntax
Evil	If Eval should be allowed	If true, JSLint allows the use of eval eval to provide access to the JavaScript compiler, which is sometimes useful, but also poses a risk of injecting your code into the attack and causing some difficulty to debug. Remember, the function constructor is also another ' eval ', and settimeout and setinterval are similar to eval when the incoming arguments are strings.
Forin	If statements need not filter	If true, then Jshint allows hasOwnProperty to be not present in the For In loop, which is typically used to traverse the properties of an object, including the attributes that he inherits from the prototype chain. And hasOwnProperty can determine whether an attribute is an attribute of the object itself rather than inherited.
Immed	IF immediate invocations must is wrapped in parens	If true, JSLint requires that anonymous functions be called as follows: (function () {//} ()); (function () {//bla bla}) ();
Laxbreak	If statement breaks should is checked	If true, JSLint does not check for line wrapping. JavaScript corrects some errors by automatically filling the full number, so this option can check for potential problems.
Newcap	If constructor names capitalization is ignored	If true, JSLint requires each constructor name to begin with a capital letter.

Filter Code	Describe	Other
Nomen	If names may have dangling _	If true, Jshint disables the underlined variable name. Many people use _name to name their variables to show that this is a private variable, but in fact, not, the underscore just makes a mark. If you want to use private variables, you can use closures to implement them.
On	If HTML event handlers should be allowed	Whether an HTML event handler is allowed.
Onevar	If only one var statement/function is allowed.	If true, the JSLint expected function is only declared once in the form of Var.
Passfail	If the scan should stop on the	If true, Jshint stops checking after the first error is found.
Plusplus	If increment/decrement should be allowed	If true, Jshint disables the self augmentation and decrement operations + + and--may bring some code reading confusion.
Regexp	If the. Should be allowed in regexp literals	If true, Jshint will not allow the use of. and [^ ...] Regular, because such a positive will often match to what you do not expect, and may be used to create some harm.
Rhino	If The Rhino environment globals should be predefined	Environment global variables that are rhino should be predefined.
Safe	If use of the some browser features should be restricted	If you use some browser features, you should be limited.
Strict	If the ' use strict '; pragma is optional	If it is true, Jshint will ask you to use the strict syntax. The Strict pattern is a new feature within ES5 that allows you to place a program or function in a "strict" scope. ECMAScript 5

Other setting	Describe
The mumber of spaces used for indentation	Specify the number of spaces between code
The maximum number of warnings reported	Maximum number of display errors
Maximum Line Length	Maximum number of characters per line
The names of predefined global variables	Pre-defined global variables
