Unable to populate the choice value in choice type field through onchange ClientScript

[VIKAS MISHRA]

On change of field "location" the field "SubCategory" is getting blank, so i need to get the value of "Subcategory" before it get blank and then populate the same value again in the "SubCategory".

But i am able to get the Subcategory choice value as a back end value of choice value with the code:

"var subCat = g_form.getValue('subcategory');"  

and when i am trying to populate that choice field back to the sub category field then its not populating it as above code is getting backend value not the lable value

Please suggest how can i populate the same chooice value(lable name) agian to the field

below is the cropped 2 line of code that i am using.

var subCat = g_form.getValue('subcategory');

g_form.setValue('subcategory', subCat);

Hi,

I didn't understand much but give you some refrences:

https://www.servicenow.com/community/developer-forum/g-form-get-label-of-choice/m-p/1729044

note: getDisplayValue() function returns the label name of a choice list.

this getDisplayValue() function is not working, as its populating nothing.

I simply wants to get the value which is already selected in  the field "Subcategorfy" and then due to some reason it gets blank and i need to populate the same value agian in that field "subcategory" 

So there should be 2 line of code 1 line of code should be getting the value which is already there selected for the field, and then another line of code should be setting the same value in that field agin.

please provide me that 2 line of code

Hi @VIKAS MISHRA ,

Where are you using these two line of code in your Onchange script? Can you give complete code?
