A regular expression would likely look like this: /http:\/\/example\.com\/api\/v3\?\S+/g Make sure to escape each / and ? with a backslash. \S+ yields all subsequent non-space characters. You can also try [^\s”]+ instead of \S if you also want to exclude quote marks. In my experience, though, regexes are usually slower than working on already parsed … Read more
They shouldn’t know anything about your back-end web service. Sounds like you are talking about making a hybird app though, which is also fine (and is technically a client).

(?:#)(?:[\w\d]+-)?([\w\d]+) First it throws out the # character, then throws out the stuff up to and including the – character, if it is there, then groups the … Read more
I think this style is not used, because the best practice is to split up code into small functions/classes/methods anyway. This way, the variable count in each scope is reduced without using scoping blocks. Unlike other languages, like Rust, where scoping has immediate consequences on memory allocation, I don’t see a huge benefit in JavaScript … Read more

Add the rating to your HTML using a data attribute: <select name=”JournalID” id=”JournalID”> <?php for($i = 0; $i < sizeof($journals); $i++) { print “<option value=\”” . $journals[$i][1] . “\” data-rating=\”” . $journals[$i][2] . “\”>” . $journals[$i][0] . “</option>\r\n”; } ?> </select> Then you can access this using jQuery .data(): (function($) { $(function() { $(“#JournalID”).on(‘change’, function() … Read more
You can proceed like this: var products = {a:”b”, c:”d”, e:”f”}; var arrList = []; for(var key in products) { // iterates over products key (e.g: a,c,e) arrList.push([key, products[key]]); }; solved Javascript object in array
Use reduce for object creation reduce takes a function as an argument and this function can take several arguments (at least 2), first is called an accumulator, it contains all sum of all previous calls of this function and the second argument is current, it contains a current value, in this case current object which … Read more
