Hey all. Having a little trouble getting this to work. I have a donation form with an input (type="text") field and a select dropdown item. By default the dropdown is disabled. The plan is when the value of the input is 50 or higher enable the the select dropdown. I also want to filter out keystrokes not between 0 and 9. In other words numeric only.
So my first implementation used the keypress event on the input field. I can get the entered character but when I attempt to get the FULL value of the input field it's prior to the new keystroke being applied. For example is the input already has a value of '23' and the user keys in '6' the value of the input is still '23' which in the keypress function. Based on my return true the new keystroke value i applied. So my second implementation I changed to using the keyup event. This allows me to get at the full value of the input field but now I'm having trouble filtering input chars. Seems with the keyup the value of the new char entered is applied to the input value display already. Which is too late to filter on. So returning false does no good. So any thoughts on the best way to tackle this? You can see a working version here http://wp7.byloudlogic.com/tip-jar/ Thanks in advance. P-
