jslint

what can I do if JSLint complains about "i" being an unused variable in such a scenario: var items = "<option selected></option>"; $.each(data, function (i, item) { items += "<option value='" + item.Value + "'>" + item.Text + "</option>"; }); (i, item) is the required order of parameters and I'm only using "item". Is there any other solution than tolerating unused variables or rewriting the $.each to use the index, both solutions which I would prefer not to do? Thanks in advance. Update: I appreciate all the suggestions but this code is simply an example to show you what I mean and I'm

JSLint (with the onevar flag turned on) is flagging some javascript code that I have with the following: Problem at line 5 character 15: Too many var statements. I am happy to fix these errors, but I'd like to know, am I doing it for performance or because it is just a bad practice and has a greater potential to introduce bugs in my javascript code. What is the reason behind the onevar flag? I did look at the JSLint docs for the var keyword but it doesn't specifically talk about why multiple var statements in the same function are bad. Here is an attempt at an example. Explain how the code

I have started using JSLint. I checked my code and I am getting this errors: Problem at line 92 character 7: Move the invocation into the parens that contain the function. })(); Problem at line 92 character 7: Wrap the entire immediate function invocation in parens. })(); How To Fix this errors? I believe this means you should move the function calling parens inside the wrapping parens (function() { /* code */ })() The two last parens that execute the function are the problem. This is how jslint wants it to look like: (function() { /* code */ }()) I found a good explanation here: http://james

I have the following javascript function that fails a jslint check function hasActiveX() { return ('ActiveXObject' in window); } jslint error Unexpected 'in'. Compare with undefined, or use the hasOwnProperty method instead. should I just live with the jslint error, or is there a better way to determine ActiveXObject? I could not find a jslint flag to skip this check? I think JSLint is asking you to try: function hasActiveX() { return window.hasOwnProperty('ActiveXObject'); } Or the other suggestion of comparing against "undefined": return (typeof(window.ActiveXObject) != "undefined");

JSLint works fine for just one JavaScript file. Recently, I've started breaking my program into several pieces. I don't want to be stringing the pieces each time I use JSLint to check my code. What is the standard solution to deal with multiples files with JSLint? Nery Jr There is a version of JSLint (node-JSLint) (command line) that allows you to check multiple files at once.

Why JSLint report in code: function cos(a) { var b = 0; if (a) { b = 1; } else { b = 2; } return b; } error: Problem at line 6 character 5: Expected exactly one space between '}' and 'else'. This error can be turned off by disabling Tolerate messy white space option of JSLint. Or in other words -- why syntax: } else { is better then ... } else { ... Google also uses syntax with } else { form. But I don't understand why. Google mentioned ''implicit semicolon insertion'', but in context of opening { , not closing one. Can Javascript insert semicolon after closing } of if block even if next token
