cursor position can go into negative

[retroisbest]

When all text has been deleted the cursor should stop at position 0, but it allows it to go into negative numbers.

to fix this i edited jsKeyboard.js

added below line 26

jsKeyboard.setcurrentElementCursorPosition = $(this).setCursorPosition(0);

amended the del: function() to force the cursor position back to 0 if it goes to anything less than.

del: function() {
var a = jsKeyboard.currentElement.val(),
pos = jsKeyboard.currentElementCursorPosition,
output = [a.slice(0, pos-1), a.slice(pos)].join('');
jsKeyboard.currentElement.val(output);
//below if statement added to reset cursor position
if (pos <= 0) {
pos = "0";
//set cursor position set at top of this script if it goes below 0 the set it back to 0
jsKeyboard.setcurrentElementCursorPosition;
jsKeyboard.updateCursor();
} else {
jsKeyboard.currentElementCursorPosition--; //-1 cursor
jsKeyboard.updateCursor();
}},

cursor position always gets reset to 0 now when it goes to negative numbers.
Hope this helps
Thanks
