The event which in the following keydown function code is not returning the correct key codes. I have checked this in Chrome using the developer tools and the console.log(e.which) statement in my code.
The .find() method does not seem to match on input fields by using a class. The ti This problem seems to be only visible on input fields. The following is a demonstration of the issue:
The site I'm working on uses a CMS (which I have no access to, nor control over the output), and in one section of the site, it outputs divs like this (I've changed the actual ID names for clarity's sake)...
Now then, I need to be able to check if a div is called 'generated-div-[number]', and I thought the best way to go about this would be to use regex. However, most of my regex experience comes from doing PHP work.
So far, I've got this...
That's a slightly simpler version of what I want it to do (i.e: in the end, I don't want to merely change the BG colour), but I mainly need some help with the regex and 'if' part of things.
I have an array of integersI like to retrieve the max number and index of max number from that array without using Math.Max() function..Presently in this below code, I have 4 dynamic values, end user will be select degree from combo box, entering the values semester, Max marks and Obtained marks as numeric values. Once entered dynamic rows will be created and it also calculate the percentage by the formula (om/mm)*100 for each row on clicking Sum and it also creates new columnŠI needed to have code when the degree changes only.. it should calculate the sum of all max.marks and Obtained marks of each semester and then calculate percentage by above formulaŠ and also new column should not be createdsort with max markswhat is the easiest way...

Does anyone know if it is possible to find out what element in the DOM made a call? Let's say I have a table and every cell has an onClick event attached to it. Is there a way to figure out what particular cell was clicked in the DOM? I know it would be easy to use ID's and just do an getElementById(), but, the ID's are generated from the system and I can't ever be sure what number any particular cell is, so I need another way if possible.
