Question

I have a code with this structure

var no_data=false;

function checkdata(){
   //reset of the global var
   no_data=false
   //some code that return an array, called data
   if(data.length==0) no_data=true;

}

Then I execute the function checkdata() and check the var no_data to do an alert if it’s true, but It updates late, in the second time I call it :S

And I tried to return in the function the errors, like no data etc, but It wont work :S

Maybe is a problem of compatibility of global scope with the livequery jquery plugin?

If you want to update no_data before execution of function checkdata.
then update it just before call of function checkdata .

no_data=false;
checkdata();
