I wish to be able to set the value of a NintexForms variable with Javascript.
I found an article on this subject wich mentions the following code.
NWF$('[data-controlname*=FormVariableName] input').val();
I’ve tried this but it’s doesn’t work
NWF$('[data-controlname*=myVar] input').val(“hello”);
Can someone help me ?
🙂

We’ll need some more details. Are you using Classic, Responsive, or New Responsive forms?
Also I’d like to know a little more about what you’re trying to accomplish. I’ve posted before about how to update a Form Variable using js but it’s almost never something that I’ve ever needed to do in production. It will be helpful to understand your situations a little better.

Good evening,
Thanks for your feedback.
In fact I use a classic form as part of a tutorial which aims to perform a page switch in a form.
function goStep(stepNumber)
{
var hiddenTxtBox = NWF$("#"+hiddenTxtBoxId);
hiddenTxtBox.val(stepNumber);
NWF.FormFiller.Functions.ProcessOnChange(hiddenTxtBox);
}The code above implies that the text field is used as a "hidden" element in order to be evaluated by a rule.
However it remains visible on the layout which is not very "clean" and I was wondering if it was possible to directly access a form variable?

the code he makes for goStep is only going to work at targeting a Form Control that has been assigned a JavaScript ID in the advanced settings. You’d need to change the function to look something like this:
function goStep(stepNumber)
{
var hiddenTxtBox = NWF$("[data-controlname='hiddenFormVar'] .nf-calculation-control-value");
hiddenTxtBox.val(stepNumber);
NWF.FormFiller.Functions.ProcessOnChange(hiddenTxtBox);
}
where the data-controlname equals the name of your Form Variable proper.
That should roughly make the function work.

Many thanks for your help, it works very well and is very clean as well.
