How do you use javascript to auto-populate a hidden form field?

Michael JC Zack

Hello all

I have been working on honeypots to protect a few forms we have. For the purposes of this question, I am using a field we created called "botEquationValue".

This code is not auto-populating the form field. What would be the correct way to approach this issue?

botEquationValue is probably the HTML name, not the id, so you should probably be for the name with getElementsByName

Thanks for the suggestion. I updated it:

Unfortunately, it is not working. I don't think my initial approach was working, which is very unfortunate. Does anyone have experience with how to approach this?

It should be working ; add a listener on page load to make sure the form has loaded before you call for the field

window.addEventListener("load", function() {

 document.getElementById("fe7642").value="999";  

});

However, if you use the id, you will have to change it for each form you create. I would suggest using the HTML name instead so you can templatize your Landing Pages

window.addEventListener("load", function() {

 document.getElementsByName("honeypot")[0].value="999";  

});

Hope this helps
