Hi there,

 

I would like to know if anyone has found javascript that would find a specific form text field name and then delete the page it is on?

 

I am working on a form that new pages will be added if the client uses a dropdown to select number of accounts and the template spawns from that. But I would like to give the client the opportunity to change the number of spawn pages if they have got it wrong. Complete novice to this. I did the original with show hide javascript but the client has asked for the pages to delete.

You can use 'page' property to find page number of a specific field, for example let's say you want to delete page where "Text1" field is located:
var f = this.getField("Text1").page;
this.deletePages(f);

Just be aware this will only work if there's only one copy of the field. If there are more copies of it, even on the same page, the page property will return an array, not a number!

PS. Also, you need to check if the page number is not -1, or you could accidentally delete the Template page (or it will produce an error).

Hi Nesa,

 

Thanks for your help. I have added the code to a Combo Box in the calculate script custom calculation area.

 

var v = this.getField("Combo Box 1").value; if (v === “two”) { var f = this.getField("Text 2").page; this.deletePages(f); } if (v=== "three"){ var g = this.getField("Text 3").page; this.deletePages(g); }

But it doesn't seem to be working.

Have I done something wrong

There are errors in your code. Check the JS Console. You must always use straight quotes, not curly ones.
