Function declarations should not be placed in blocks. Use a function expression or move the statement to the top of the outer function

由 怎甘沉沦 提交于 2019-11-27 03:51:05
问题 I have the following code: if (typeof console === "object" && typeof console.error === "function") { function e(msg) {"use strict"; console.info(msg);} } For which jsLint gives the following error: Function statements should not be placed in blocks. Use a function expression or move the statement to the top of the outer function. Why is it giving this error and what does it mean? 回答1: You should not be creating function inside if block. You are much better off doing: var e = function(){}; if

Why is JSHINT complaining that this is a strict violation?

由 旧城冷巷雨未停 提交于 2019-11-27 03:47:47
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 inappropriate? Is this considered to be bad style? JSHint says "Possible strict violation" because you are using

This question already has an answer here: How to fix jslint error 'Don't make functions within a loop.'? 6 answers What would be the correct way to solve the jslint error in this case? I'm adding a getter function to an object which uses this. I don't know how to do this without creating the function inside the loop. for (var i = 0; i<processorList.length; ++i) { result[i] = { processor_: timestampsToDateTime(processorList[i]), name_: processorList[i].processorName, getLabel: function() { // TODO solve function in loop. return this.name_; } }; } Rob W Move the function outside the loop:

问题 Possible Duplicate: JSLint: was used before it was defined I run JSlint and saw errors like that: 'foo' is not defined. var x = foo(); foo is a function defined in another JavaScript file foo.js .

How can I fix this error repoted by JSlint ? 回答1: Use the global directive to tell JSLint about foo 's assumed existence. /*global foo */ http://www.jslint.com/help

JSLint “insecure ^” in regular expression

由 倾然丶 夕夏残阳落幕 提交于 2019-11-27 01:56:55
JSLint reports Insecure '^' for the following line. Why is that? Or is it just going to complain any time I want to negate a character class? // remove all non alphanumeric, comma and dash characters "!$7s-gd,&j5d-a#".replace(/[^\w,\-]/g, ''); It only will do this if you have the option selected at the bottom: Disallow insecure . and [^...] in /RegExp/ From the docs : true if . and [^...] should not be allowed in RegExp literals. These forms should not be used when validating in secure applications. So the answer your question, if you start a regex with ^ and it's checked, yes it'll throw the

Prevent JSHint warning that 'functionName is defined but never used'

由 倖福魔咒の 提交于 2019-11-27 01:00:34
问题 I have just started using JSHint (through the Sublime-Linter package for Sublime Text 2). I would like to suppress its warnings regarding functions that are used before they are defined, as I see no problem with using function definitions like this. For example, the following code generates warnings: (function($){ $(document).ready(function() { formValidationSetup(); refreshErrorMessages(); }); function formValidationSetup() { } function refreshErrorMessages() { } })(jQuery); The warnings:

The “unexpected ++” error in jslint [duplicate]

由 醉酒当歌 提交于 2019-11-26 23:57:09
问题 This question already has an answer here: Why avoid increment (“++”) and decrement (“--”) operators in JavaScript? 17 answers What is the best practice for that then? Jslint explains that it "adds confusion". I don't see it really... EDIT: The code, as requested: var all,l,elements,e; all = inElement.getElementsByTagName('*'); l = all.length; elements = []; for (e = 0; e < l; (e++)) { if (findIn) { if (all[e].className.indexOf(className) > 0) { elements[elements.length] = all[e]; } } else {

Function declaration in CoffeeScript

由 蓝咒 提交于 2019-11-26 19:26:59
问题 I notice that in CoffeeScript, if I define a function using: a = (c) -> c=1 I can only get the function expression : var a; a = function(c) { return c = 1; }; But, personally I often use function declaration ,for example: function a(c) { return c = 1; } I do use the first form, but I'm wondering if there is a way in CoffeeScript generating a function declaration. If there is no such way, I would like to know why CoffeeScript avoid doing this. I don't think JSLint would holler an error for

JSLint error: “Move the invocation into the parens that contain the function”

由 烈酒焚心 提交于 2019-11-26 19:16:43
问题 What does JSLint mean by this error? And how should it be rewritten? Error: Problem at line 78 character 3: Move the invocation into the parens that contain the function: })(jQuery); 回答1: To pass JSLint's criteria, it needs to be written like this: }(jQuery)); Though I think that particular criteria is a bit subjective. Both ways seem fine in my opinion. (function () {})() makes a bit more sense to me since you wrap the full function, then call it (function () {}()) looks like you're wrapping
