[flexcoders] Search while you type?

[Greg Johnson]

I return a list from a database into a datagrid.  I then have a text 
entry field with a keydown event set to call a function.
The function runs though the currently loaded like, compares what is in 
the text entry field's .text property and creates a array with only 
those entries then resets the dataprovider parameter of the datagrid to 
the filtered list.  Here is the code

private function filterlist() {
var TempObject:Object = new Object();
var RunningArray:Array = new Array();
for(var i=0; i  OTD_TECH_RESULTS.dataProvider.length; i++){
 TempObject = OTD_TECH_RESULTS.dataProvider[i];
 if ( TempObject.INTERNAL_CASE_NUMBER.indexOf(search.text)) {
 RunningArray.push(TempObject);
}
}
OTD_TECH_RESULTS.dataProvider = RunningArray;
OTD_TECH_RESULTS.dataProvider.dispatchEvent({type: modelChanged});
}

INTERNAL_CASE_NUMBER is one of the columns

What happens is that it gives me no entries once I type the first 
character, and even when I got it to return results it wouldn't seem to 
update once I hit a second key unless I hit backspace first.

I am using indexOf because I couldn't find a find command anywhere.

Any ideas how I can make this work?

Re: [flexcoders] Search while you type?

I did some sniffin around and got mine to work right. For anyone
interested I made a kinda generic version below.

// sourceArray = any array
you are currently using as a datasource, most likely it will be
preloaded with entries
// search = the ID of the text entry field you want to use while typing
private function
filterlist() {
 var TempObject:Object = new Object(); // This will hold a source
structure
 var RunningArray:Array = new Array(); // This will become the new
dataSource for the datagrid
 var compString:String = new String(); // This will have just the
element of the TempObject you want to test
 // Start Looping over the original datasource
 for(var i=0; i  sourceArray.length; i++){
 TempObject = sourceArray[i]; // Assign the current
source row structure to the TempObject
 compString = TempObject.TITLE; // Assign the comp(are)String to
the Element you want to filter on
 // check of the text property of most likly a text field, if it is
in the compString
 if ( compString.indexOf(String(search.text)) = 0 ) {
  RunningArray.push(TempObject); //If it is a match, add the row
from the source to the filtered array
  }
 }
 destinationDataGrid.dataProvider = RunningArray; // Rebind the
DataGrid to the new filtered array
 destinationDataGrid.dataProvider.dispatchEvent({type:
"modelChanged"}); // Dont know if this is needed, may work without.
}

No wildcards or anything like that are needed, esentialy its
just like searching with the astrix wild character on each end of
whatever you type. Its pretty fast since the data is already loaded
into memeory

Hope this helps someone
