How to make Reset button that resets selective fields only in LiveCycl

Start off by adding a regular button to your form. Then add some code to the click event to do the reset.

xfa.host.resetData("xfa.form.form1.myField1,xfa.form.form1.MyField2");

notice that the full hierarchy path is required for this function. This is called the SOM path, and you can find it at the top of the "Scripting" window when you click on a field in the design window.

Just to make sure I understand, if I have 30 fields on a form and I want to reset all of them except one, I would have to put the names of all 29 fields that I want reset in the javascript? There is not a quick way to just exclude one field?

Well, yes and no. This entry in the XML Form Object Model Reference states the input to "resetData" is:

There is a whole reference on writing SOM expressions. So you can in fact write an expression that references more than one field, but I don't know about writing one that excludes a field. You can find this document here:

http://kb.adobe.com/selfservice/viewContent.do?externalId=330467&sliceId=2There is also another way to do this, and that's to write code to build the input to the function. I believe I already answered a question very much like this. Search the forum for posts using the word "resetData".

I appreciate your help. I have seen some of your tutorial videos and they have been very helpful. My problem is that I have no scripting background. I found this answer in another post to the forum, but I just don't know what to do with it. Could you help just a little more?

"Next, since you are using a LiveCycle form you should use the reset function for LiveCycle JavaScript.

xfa.host.resetData();

Unfortunately, there isn't a function for resetting everything except a few fields. If there are too many fields to write it all in a single reset, and you can't group the non-reset fields into a subform, you'll have to write a function to do this.

Actually, it isnt' too bad. The XFA layout DOM has a function that returns a collection of all the fields on a page.

xfa.host.pageContent(pgNum,"field");

Use this function to walk through all fields on all pages to get the full SOM paths of all the fields, excluding of course the ones you don't want reset. Then just pass the final list into the "xfa.host.resetData()" function."

I don't understand how to use "xfa.host.pageContent(pgNum,"field");" Where do I put it or how do I run it to get the list of field names?

In order to use these methods you're going to have to learn just a little bit about JavaScript.

The pageContent function returns a Collection object. This is a commonly used type of object in LiveCycle.

For example, to reset all the fields on page 1 except for one called "MyField" the code would look like this.


Place this code in a button and modify it to exclude your field. If the form has more than one page, the code will have to be modified to get fields form al the pages.

Good Luck,

Thanks so much Thomp. I had to discern that the subform was named Pg1 also. Once I changed mine to match, it worked!

Besides resetting the data, I would like to have fields that have been dynamically (programatically) added to revert back. is this possible?

What do you mean by "revert" back? Do you mean removed from the form? Were these fields added with the instance manager? If they were, then there is a removeInstance() fucntion that will deleted the fields from the form.

Yes, I was trying to avoid having to call the instance manager. Since I know how many instances I originally placed in the form, I can remove any extra ones. I was just hoping for some magic :-).

By the way is there a way to query the subform to find out the initial number of instances? I do not need it this time, since I have two subforms which start with one instance each, but I can imagine more complicated situations. Besides, it would be better programming.

Thanks again.

Yes, the instance manager has a "count" property, and each subform instance knows it's own index.
