Refresh control

[coold70505603]

I have a pdf where the user enters info and the last page does all the calculation.  The calculation is done in the fields, it involves averages.  It is slow because each time any information is entered all the fields on the last page recalulates.  I would like to switch off recalculation on that page until the user clicks a "calculate" button.  Is that possible?

Or even if I could switch off refresh for the entire document until a button is clicked.

I found this code but I am not sure where to put it or how to make it work.  Can anyone help?

Thanks in advance

{

        this.delay = true;

}

{

        this.delay = false;

}

You can use the calculations at the "calculate" button.

Would I then put all the calculations into the button?  There are a lot of cacluations in the fields involving mean average.  I would not know how to start this in javascript.  Perhaps I have not been clear, I need the fields on page 9 of my document or my whole document not to caculate until I press a button. Many thanks

What calculations do you use?

[coold70505603]

Hi Bernd

I am pulling the values from a number of fields and using the average function. Then I pulling information from those fields to make a mean average.  The field calculation works a treat. No complaints.  It is just that for speed I want them to do the calculation at the end once all the data has been entered.

Many thanks for any help you can give

Use the "calculate" property, instead.

[coold70505603]

Hi,

Thanks for your reply

Not sure what the calculate property is?

[try67]

Instead of "this.delay" use "this.calculate".

[coold70505603]

Ok.

Would I put this in a button?

That would make the fields calculate but I need then to NOT calculate until I press the button.

How would I stop the fields from refreshing?

I am a beginner with javascript so what would the syntax be?

[coold70505603]

Brilliant!! Got it.  I did 2 buttons 1 to turn the calculations off 1 to turn them on.  Thank you so much.

Now, is there a way to automatically turn off the calculation with a document is opened?

That way I would only need 1 button to calculate the end page?

[try67]

Yes, add the code to stop the calculation under Tools - JavaScript - Document JavaScripts.

[coold70505603]

Thanks to both.

Works.  Only thing I am left with is when I click the button to switch back on calculation I then have to enter information in any field to make the document refresh and calculate all fields.  Is there a sub command I could put in the this.calculate button that makes it calculate NOW.

Again, many thanks in advance, much appreciated

Yes: this.calculateNow();

Just wanted to say thanks again. Help much appreciated, especially for a beginner
