[Solved] 2.7.6 python version needs parenthesis to print?

by

Your impression is correct, it’s not needed (unless of course you import print_function von __future__!).

Note that (x) does not create a tuple containing x (that would be (x,)). solved 2.7.6 python version … Read more

[Solved] Class query PDO property of non-object

by

PDOStatement::fetchAll() already returns an array so you’re just double-nesting the result set for no reason. In your model::find() method, change these lines… while($data = $query->fetchAll(PDO::FETCH_OBJ)){ $d[] = $data; } return($d); to return $query->fetchAll(PDO::FETCH_OBJ); You can also remove the model $d property (not that you were using it anyway). 1 solved Class query PDO property of … Read more

Since nothing in JavaScript specification says length must be exactly one higher than the last index, your demand is not reasonable. In common use, dense arrays overwhelmingly outnumber sparse ones. Since JavaScript does not keep indices in an ordered structure, finding out which index is the last every time array contents change would incur a … Read more

[Solved] Convert string to date format using javascript

by

A little workaround could be the following, but if you have to manipulate dates a lot, I strongly recommend you to use the Moment.js library: https://momentjs.com/ var strDate = “2016-11-20”; var utcDate = new Date(strDate).toUTCString(); var convertedDate= utcDate.substring(utcDate.lastIndexOf(“, “) + 1, utcDate.lastIndexOf(” 00:”)); console.log(convertedDate.trim().replace(/\s/g, ‘-‘)); Pay attention that the implementation of this method may change … Read more
