Set Value doesn't save values when I click on Submit button

Question

I have a page where I'm setting the value of text boxes using document.getElementById, but when I'm clicked on "Guardar" button the values doesn't saves, how can I solve?

This is the code:

document.getElementById("Crm_CustomModule3_COBJ3CF82_LInput").value = "01/10/2022"

This is the text field that I set (vigencia hasta):

And this is the page after y clicked on "Guardar" button

The value doesn't saves.

Answer 1

Have you have input textbox id as Crm_CustomModule3_COBJ3CF82_LInput

Answer 2

You probably need to trigger the onChange or onInput listener to save your input. Depends on the site structure. Something like:

element.dispatchEvent(new Event('change',{'bubbles':true}))

or

element.dispatchEvent(new Event('input',{'bubbles':true}))
