When I said X and Y I was talking about a table/grid with an “X” and a “Y” dimension.
I never said entering in coordinates, just that this client would look across the top row (“X”) and find something (e.g. # of Dents) and then look down the left column (“Y”) and find something (e.g. Size of Dent) and click on the appropriate button in the table.
So I just need to learn HTML5 and JavaScript and I could fairly easily build a Touch-Screen Estimation program using purely a “responsive” website, right?
What I was saying is that I can’t use JavaScript to process a “Touch” on my MacBook Pro, because it presumably doesn’t have sensors in it to recognize a “touch”, right?
There is no “touch” event in Javascript. There is only “click”. And click can be performed by many ways depending on device. On MacBook you point with mouse and click. On iPad you tap with finger. But both of these actions are equal for Javascript code. You just listen when user “clicks”.
If I can program tens of thousands of lines of code in PHP, I assume I can survive JavaScript…
So, Steve, if I came to you with this requirement, how long would it take YOU to build…
Build a touch-screen web application that...
- Displays 20 buttons, each with a unique cost
- Allows multiple buttons to be touched
- Keeps a running total of all buttons touched
- Writes the entries into MySQL
- After "Submit" is touched, creates a Work-Order Total and displays it on the screen and stores it in the database.
Just make a web page.
Use HTML to create the elements
Use CSS to style the page (making it responsive, for example)
Use JS to deal with the button clicks and calculate a running total
Use Ajax to submit the values to a PHP backend where you can write them to a DB.
In JavaScript you can handle touch events thus (assumes jQuery):
So how long would it take you to build such a program? (It doesn’t sound too bad to me…)
BTW, what would you call such a program?
When I hear “app”, I think of “application compiled for a mobile device”. Would this be a “website”? Or could it be considered a “web app” - whatever that is…
