Filtering ArrayCollection using RegExp
Hi there,
I'm trying to filter an AC using RegExp. The requirement is wild character
search. i.e, if I enter 'A*' (asterisk), then I need to display all items
that start with 'A'.
I haven't used RegExps much before. I feel I'm missing something here.
Coudn't get much on net either. Can you kindly help me on this?
This is the code:
if(tiSearch.text.indexOf('*') > -1)
{
var searchText:String = tiSearch.text.slice(0,
tiSearch.text.length - 1);//trying to remove * and use only the characters
here
dataLoader.atcDetailsList.filterFunction =
function wildCardfilterATCs(item:Object):Boolean
{
var regExp:RegExp = new RegExp(searchText,
"w*");//not working
return regExp.test( item['AtcDesc'] );
}
}else
{
dataLoader.atcDetailsList.filterFunction = function
filterATCs(item:Object):Boolean
{
searchText = tiSearch.text
var regExp:RegExp = new RegExp( searchText, "i"
); //this works fine, without asterisk. Lists all items that has search
character anywhere in the item.
return regExp.test( item['AtcDesc'] );
}
}
dataLoader.atcDetailsList.refresh();

Hi Kessler,
I didn't knew about that class! It's great. Typically, I wanted 'contains'
, 'starts with' and 'ends with'. All of it is there.
I was using flex 3 in my project. So, i'll just replicate this class in my
project. Thanks again, that was helpful.
Cheers!

Try [1] to see if it makes it a little easier assembling a regex pattern. It can create the pattern as a string or create a RegExp with the pattern already assembled.
RegExPatterns.createRegExp("my search value", RegExPatterns.CONTAINS);
RegExPatterns.createPatternString ("my search value", RegExPatterns.CONTAINS);

Hi Alex,
Thank you so much.
First one didn't work, but the second option did.
Yes, regex is quite powerful I believe and surely I'll practice it going
forward. Thanks again.
Cheers!

var regExp:RegExp = new RegExp(searchText, searchText+".*")
That doesn’t look right. I would think it would be:
new RegExp(searchText+”.*”, “”)
I think you can also try:
new RegExp(“^”+searchText+”.*”, “”)
I think there may be some internet sites where you can practice regex.

'A' here would be dynamic. It actually can be anything which user enters in
the search text input. Based on your suggestion, I tried this code, still
not getting it right:
if(tiSearch.text.indexOf('*') > -1)
{
var searchText:String = tiSearch.text.slice(0,
tiSearch.text.length - 1);
dataLoader.atcDetailsList.filterFunction =
function wildCardfilterATCs(item:Object):Boolean
{
var regExp:RegExp = new RegExp(searchText,
searchText+".*"); //searchText = 'A'
return regExp.test( item['AtcDesc'] );
}
}
If I enter 'A*' it shows me all the items which has 'A' in it irrespective
of it's location within the item.
