Reset a single field in repeated Subform...I cannot seem to reference it....

[Natalieann75]

Good morning

I am trying to reset ONE field in a repeating subform.  I don't want to hide the instances of the subform for this action, or re-set the entire form.  

The field I wish to reset is form1.Main.sfOMKT.Table1.Row3.sfFigs.numFigures and sfOMKT is the repeating subform which it lives in. 

Obviously this works great for the first instance: xfa.host.resetData("form1.Main.sfOMKT.Table1.Row3.sfFigs.numFigures");

But no matter how much I read I cannot grasp the referencing thing...

Would anyone be able to help?

I am assuming by resetting the field, you want to set its value to null or empty.

Then try this script.

var subforms = this.resolveNodes(" form1.Main.sfOMKT[*]");

for(var i =0; i<subforms.length;i++)
{
subforms.item(i).Table1.Row3.sfFigs.numFigures.rawValue = "";

  }

Works beautifully.  Again you save me

You need to specify the instance's index of the repeating subform to target. 

so if the action is triggered by an event linked to a cell in the same row as the field to be reset,you could do something like this:

// determine the index of the targeted instance of the repeating form

var TargetIndex = this.parent.parent.parent.index; 

// create the string representing the SOM of the targeted field

var TargetCell = "form1.Main.sfOMKT["+TargetIndex+"].Table1.Row3.sfFigs.numFigures";

// reset the value of the targeted cell

xfa.host.resetData(TargetCell);

Thank you so much @MHWinter !!

Hi,

you can use the resolveNodes() method, to reference multiple instances in an object.

Here's an example. You're creating a node list for all instances of sf0MKT named oSubforms. 

Then you're using a for loop to process every node in the list.

var oSubfoms = form1.Main.resolveNodes("sfOMKT[*]),
    i = 0;

for (i; i < oSubfoms.length; i += 1) {
    var oNode = oSubform.item(i);
    oNode.Table1.Row3.sfFigs.numFigures.rawValue = null;
}

Thank you so much!!!  I don't know where I would be without this forum.

For a self starter I have made some pretty decent bespoke forms for my organisation largely thanks to the help of you guys here when I hit a roadblock.

I really want to understand how you know to use stuff like this 

for (i; i < oSubfoms.length; i += 1) {

Can you recommend anything for a total beginner for JS?  Course, reading material?  I read a LOT of stuff and sometimes can work it out for myself, but I lack the basic knowledge so I don't think I will ever progress until I get that base....
