[Proto-Scripty] Re: script.aculo.us autocomplete: Restrict to list
Just do an onkeypress event. Check the value of the field, and if it
doesn't match what you want, delete the last character and loop until
the form field value returns results from your list of acceptable
words. You will want to loop in case they somehow get multiple
letters entered before your script has a chance to check the field
value.

[Proto-Scripty] Re: script.aculo.us autocomplete: Restrict to list
So I was looking at something that would only let them type values
that appear in the autocomplete list. So, say it was a state list
(for example). If you type in "cal" you would have California showing
up in the list. Current autocomplete behavior allows them to type in
"Calasdfasdfasdfasdf" or whatever. I'm curious if there is a solution
already implemented that would let them type CAL and would ignore
everything else until they typed the IFORNIA in the correct order. In
other words, they're restricted to only the items on the autocomplete
list. If we have , AAAB, AAAC then after they type AAA the only
options allowed to type would be A, B, or C.

[Proto-Scripty] Re: script.aculo.us autocomplete: Restrict to list
Should be pretty simple:
var array = //your array of acceptable values;
$('field).observe('keyup', checkword);
function checkword()
{
var string = '/^' + RegExp.escape($('field').value) + '.*/';
if(array.grep(string).length == 0)
return false;
else
return true;
}
Is a rough start of something.

Your code has to provide the options which can be offered in the Autocomplete, so can you not arrange to generate only the restricted set you want? -- You received this message because you are subscribed to the Google Groups "Prototype & script.aculo.us" group.
