I'm attempting to ensure an array of unknown length is split in one-or-more arrays with a maximum of 20 elements. I've searched around and found several answers for similar questions based on arrays containing number sequences (or maybe I'm just missing something), but nothing for an array of strings. I've come up with a solution, but it seems a little convoluted and I feel it could probably be better. For example, take this array - And for the sake of this example, that's say I want only a maximum of two elements - So now I have an array of arrays - But... Can I achieve my goal in a more efficient way? Use a for loop, the range operator ( .. ), and the unary array construction operator ( , ): [array]$keys casts the key/value collection .Keys to a generic array (so that the index operator can be used on it). The expression $i..($i+$size-1) gives you the indexes from $i up to the index before $i+$size , i.e. the next $size elements from the array starting at pos...

I have two data file Test1 and Test2. Test1 datas: Test2.txt test4.txt(Output file) My code: The output I get is something like that: [1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0, 9.0, 10.0, 11.0, 12.0, 13.0, 14.0, 15.0, 17.0] But the remaining columns are not there in my output. I take the 1st Columns of both file as my key attribute and insert element depending upon there ordering. What should I do to get my desire output? I would create a class to keep your data in. Something like: You can then keep an ArrayList, reading one lines values into one MyData object. You could then use Collections.sort(that arraylist) to sort it, and then iterate over it and print it to your file.

I have a PDF form with 6 different time periods for each day of the month and I need to make sure those time periods do not overlap when the user completes them. Not all time periods may be completed, but the ones that do must be unique. I have taken inspiration from this previous post Use JavaScript to compare time ranges specifically the contribution by @RobG. However, my lack of scripting knowledge is hampering my ability to mold that code for my specific application. In addition to have the time periods verified, I also have to repeat this for every day on the form but I would like to do it one day at a time particularly when the entries are made for that day. Since this is a PDF form, I am not certain how to execute that validation. For example, should it execute every time a time period is completed? That is, have a Start Time and and End Time? So it would act as a "validation" script for that time entry? Here is a sample of what the form looks like: Here is my ...

I want to display like convert JSON data to array objects how can solve this problem using jquery or js? JSON data : To array object: one more pattern I need it I have an array like this in Ruby to convert into add as key entry static Firstly note that you do not need jQuery at all for this. jQuery is primarily a tool for amending the DOM. To work with data structures like this native JS is all you need. To achieve what you require, you can use Object.keys() to get the keys of the 0th object in your original array, then you can loop over them using map() to build a new 2 dimensional array from that data: Its simple enough. Just enter the array into Object.entries(). like this Object.entries(originalArr[0]) A simple one-line alternative: By clicking "Post Your Answer", you acknowledge that you have read our updated terms of service, privacy policy and cookie policy, and that your continued use of the website is subject to these po...
