Spawning Refreshed Dynamic Templates

I am trying spawn (unlimited times) two blank template pages (upon push of a button) that still leverage the custom field-level javascript that has been developed on the page. Using the following script, it will spawn each template (refreshed), but the field-level custom javascript does not work. Is there a way I can add code to each javascript that will dynamically update the field header when spawned?

Code is as follows:

var NextPageIndex = this.pageNum + 1;

if (event.target.value == "Off")

{

    this.deletePages({nStart:NextPageIndex, nEnd:NextPageIndex});

}

else

{

    var a = this.getTemplate("User_Page2");

    a.spawn(NextPageIndex, true, false);

    var PageName = "P"+NextPageIndex;

    this.resetForm(PageName);

    var a = this.getTemplate("User_Page1");

    a.spawn(NextPageIndex, true, false);

    var PageName = "P"+NextPageIndex;

    this.resetForm(PageName);

}

RefreshPageNumbers();

You haven't shown any of the field level scripts and even said anything about what they do, but I imaging they use the names of fields on the page. As you probably know, the names of the fields change on each of the spawned pages. You didn't say, but I imagine this is your problem, i.e. your scripts are written for fields names that don't exists on the page?

So the solution is to create the needed field names dynamically, from the name of the element on which the script is acting.

For example say you have field A, B, and C. Where the calculation script for C is

event.value = this.getField("A").value + this.getField("B").value.

The new tempate name for C is something like "User_Page1.Page#.C".   All you need to know that everything in front of "C" is the prefix for all fields on the page. So you create new field names like this.

var aParts = event.targetName.split(".");

aParts.pop();

var cPrefix = aParts.join(".");

Now you can use this prefix to get the field names specific to the page. Just add this code to the top of each field script. and change the get field to

this.getField(cPrefix + ".BaseFieldName")

Mostly the scripts trigger other fields to show/hide based on checkboxes, with the occasional alert box.

Your assumption was spot on. I tried your script with no such luck. I was trying a similar script as follows:

var FieldName = this.event.target.name;

if (FieldName.substr(3,8) == "Section3")

{

var PageHeader = FieldName.substr(0,16);

}

else

{

var PageHeader = "";

}

if (this.getField(PageHeader+"Field X").value == "Other")

{

this.getField(PageHeader+"Field Y").display = 0;

}

else

{

this.getField(PageHeader+"Field Z").display = 1;

}

My script works perfectly. And it works generically for any template or field name.

What about it wasn't working when you added it to your script. Were there error messages reported in the console window? What debug did you do?
