How to pass parameter while call a function using setInterval. viz. setInterval('funca(10,3)',500); is incorrect.

I have a 2.67 GHz Celeron processor, 1.21 GB of RAM on a x86 Windows XP Professional machine. My understanding is that the Android emulator should start fairly quickly on such a machine, but for me it does not. I have followed all instructions in setting up the IDE, SDKs, JDKs and such and have had some success in staring the emulator quickly but is very particulary. How can I, if possible, fix this problem?
You need to create an anonymous function so the actual function isn't executed right away.
ReplyDeletesetInterval( function() { funca(10,3); }, 500 );
You can use an anonymous function;
ReplyDeletesetInterval(function() { funca(10,3); },500);
Quoting the arguments should be enough:
ReplyDeleteOK --> reloadIntervalID = window.setInterval( "reloadSeries('"+param2Pass+"')" , 5000)
KO --> reloadIntervalID = window.setInterval( "reloadSeries( "+param2Pass+" )" , 5000)
Note the single quote ' for each argument.

You can pass the parameter(s) as property of the function object, not as a parameter:
ReplyDeletevar f = this.someFunction; //use 'this' if called from class
f.parameter1 = obj;
f.parameter2 = this;
f.parameter3 = whatever;
setInterval(f, 1000);
Then in your function someFunction, you will have access to the parameters. This is particularly useful inside classes where the scope goes to the global space automatically and you lose references to the class that called setInterval. With this approach "parameter2" in "someFunction", in the example above, will have the right scope.
This is not exactly the same parameters as I read here:

I'm a bit confused ...
This works setInterval("foo(bar)",int,lang); Jon Kleiser lead me to the answer.
ReplyDeleteAdd them as parameters to setInterval:
ReplyDeletesetInterval(funca,500,10,3);
