Delay between functions

Post by David wyatt »

Hi,

On a button click i have a list of javascripts running in order. What i need is for there to be a delay between 2 of them. ive tried adding a run javascript with following text

window.setTimeout(Functionwait, 1000);
function functionwait() {
}
but is just stops the list commands at this point and doesnt execute any others after.

thanks Image

Hello,

You can write all code on one click event, then time out should work as expected.

Hello!

You invoke all handlers on the same event. It would be better to join them in one code and invoke with delay as you specified using setTimeout for each function. Or if you want to guarantee functions execution sequence, use callbacks:
prefunction foo(params, callback){
// do stuff with params

// move on to next step
callback(params)
}

function bar(params, callback){
// do stuff with params

// move on to next step
callback(params)
}/pre

I am using your code like this. I want the database service executed than the mailto window open and then it navigates to start page alerting the success.
Am I using your code correctly?
pre
function foo(params, callback){
databaseService.execute({});
window.open('mailto:someone@example.com?subject=any&body=any');

callback(params);
}
function bar(params,callback){
window.open('mailto:someone@example.com?subject=any&body=any');
Apperyio.navigateTo('StartPage', {});

callback(params);
}
/pre

Hi Umana,

You don't need such technique.

So the solution is:

1 On first service "Success" event add "Run javascript" event handler.

2 Populate it with following js code:

pre

Code: Select all

 window.open('mailto:someone@example.com?subject=any&body=any');  

 Apperyio.navigateTo('StartPage', {}); 

/pre

Regards.
