[flexcoders] Sleep function in ActionScript?

Wed, 31 May 2006 15:55:53 -0700

Hi all,

 

I have this bit of code that does some simple things, but my timing is off.  What I do is I make a webservice call to some server, and the server returns me a string of XML.  After that, I parse that string of XML into an XMLDocument object, to use as a data provider for a repeater.  That's it.  Here is a simple version of my code.

 

WebserviceCall();  // this function returns the result as an XML string and puts it

                   // into a String variable called string_result on event.COMPLETE

xml_result.parseXML(string_result);

my_repeater.dataProvider = xml_result;

So this al works fine when I do each one of these steps separately.  But when I try to do them in succession, I get an error on the line that tried to parse the XML.  This is because it takes a while for the server to return the XML result and put it into string_result.  So, when the application tries to execute the next line, it tries to parse an empty string into XML, which obviously fails on me. 

 

What I tried already, was putting a simple loop in before the parse call to make sure that the String is not null...

while (!string_result);  // wait until string is not null before continuing

...but this eats up my resources and crashes the browser.  So, I am wondering if there is a sleep function in ActionScript, so that I could go...

 

while (!string_result) sleep(1);  // sleep for 1 second before repeating loop

                                  // hopefully this won't stress the system as much

 So that's my plan of attack.  I know that sleeps are kind of "hack" fixes, so any other suggestions are welcome!

 

Thanks in advance!
