Then remove if else. No need to call function twice.

Hi,

Yes it is possible, it's know as a recursive function.

Have a look here or here for an example and explanation.

... hope it helps.

I don't think recursion would be helpful to OP. See his comment below the question.

hypermellow 13-Feb-15 4:01am

What do you mean? ... an explanation, with links to the definition of recursion is completely relevant to the posted question.
The OPs later comment was in response to your question.

Thanks7872 13-Feb-15 4:19am

I just wanted to let you know the OP's exact issue. I mean that recursion will not help him in any way.

hypermellow 13-Feb-15 4:26am

Ah, I see ... thanks.
What is the OPs exact issue then? ... I thought he was asking if it was possible in Javascript to call a function from within itself?

Thanks7872 13-Feb-15 4:29am

He wants to call else part after if part completes the execution. See my comments below the question.

hypermellow 13-Feb-15 4:47am

'else' conditions get executed when the 'if' condition has not been met ... unless you call your function again (ie - using recursion).
The examples in the links I posted demonstrate this.

Thanks7872 13-Feb-15 6:29am

:laugh:

You still misunderstood. If you are suppose to execute if, you are suppose to execute else then why to write if else in first place?

e.g


if(true)
{
alert("First part")
}
else
{
alert("Second part")
}

Now he wants that there should be two alerts : First part And Second part.

Why not to simply write


alert("First part")
alert("Second part")

?????

I don't need an explanation on how conditional statements run, thanks ... and I'm not the one who has misunderstood.

Regardless of you thinking it was not helpful to the OP, the response I posted addresses his question ... as it explains the technique that he was asking if it was possible.

After I post my response, you then asked the OP a separate question, received a response that contains a snippet of code that shows ...*drum roll please* ... a recursive function!

So, based a badly demonstrated code snippet, that show no logic, nor purpose of the function ... and your making up stuff about what the OP actually wants?? ... where does the OP state he wants to show any alerts, never mind he wants to show 2 alerts???

If the OP was asking how conditional statements work, then why would he ask if recursion was possible?

Thanks7872 13-Feb-15 7:49am

He asked for recursion because he didn't know whether recursion can help him or not. Would you please point me to the statement where op asked how conditional statements work?

hypermellow 13-Feb-15 7:54am

I never said the OP asked how conditional statements work ... the last line of my previous comments starts, ironically, with the word 'if' :)
