阅读更多关于 JSLint says “missing radix parameter”

问题 I ran JSLint on this JavaScript code and it said: Problem at line 32 character 30: Missing radix parameter. This is the code in question: imageIndex = parseInt(id.substring(id.length - 1))-1; What is wrong here? 回答1: It always a good practice to pass radix with parseInt - parseInt(string, radix) For decimal - parseInt(id.substring(id.length - 1), 10) If the radix parameter is omitted, JavaScript assumes the following: If the string begins with "0x", the radix is 16 (hexadecimal) If the string

This question already has an answer here: Location of parenthesis for auto-executing anonymous JavaScript functions? 4 answers I know this is silly, but there's any difference between this: (function() { var foo = 'bar'; })(); and this? (function() { var foo = 'bar'; }()); JSLint tells us to Move the invocation into the parens that contain the function , but I see no need to. Edit: The answers are too cool. ~function , the JSHint alternative along with jQuery's preference for (/***/)(); and Crockford's explanation! I thought I was going to just get a "they're the same thing" kind of answer.

问题 JSLint site updated, and I cannot check JS scripts anymore. For me, this warning is not critical, and I don\'t want to go through thousands of lines to fix this, I want to find more critical problems.

UPDATE Example: function doSomethingWithNodes(nodes){ this.doSomething(); for (var i = 0; i < nodes.length; ++i){ this.doSomethingElse(nodes[i]); } doSomething(); // want to find this problem } jslint.com output: Error: Problem

问题 This question already has answers here : Why to avoid creating objects in JavaScript? (2 answers) Closed 2 years ago . I entered this statement in JSLint: var number = new Number(3); And received the following message: Do not use Number as a constructor. Why is that? The statement is creating a number object, not a primitive value, so I don\'t see why using new is a problem. EDIT: Thanks for all the responses. They\'ve got me thinking further, so I posted a follow-up question here. 回答1: In

问题 I think this may be a duplicate of Strict Violation using this keyword and revealing module pattern I have this code: function gotoPage(s){ if(s<=this.d&&s>0){this.g=s; this.page((s-1)*this.p.size);} } function pageChange(event, sorter) { var dd = event.currentTarget; gotoPage.call(sorter, dd[dd.selectedIndex].value); } And JSHINT (JSLINT) is complaining. It says \"Strict violation.\" for the highlighted line: Is my use of Function.call() and then referencing the instance, somehow

问题 I have some code that invokes anonymous functions within a loop, something like this pseudo example: for (i = 0; i < numCards; i = i + 1) { card = $(\'<div>\').bind(\'isPopulated\', function (ev) { var card = $(ev.currentTarget); .... JSLint reports the error \'Don\'t make functions within a loop.\' I like to keep my code JSLint clean. I know I can move the anonymous function out of the loop and invoke it as a named function. That aside, here\'s my question: Would a Javascript interpreter
