how to set and clear a value when a form is submitted

Recommended Posts

It’s my first post so here I go.


I have been taking a course on HTML and I’m already familiar with C.


I need to submit a value from a hidden input field when the form is submitted, this works fine, however what I need to do is submit a new value 2 seconds after the first one has been submitted.


I need to make this happen without any additional buttons.

The code below (without CSS) writes the value to my application just fine but I dont know how to submit a second value 2 seconds later.


Hoping someone can help

I have noticed that I have to use input type as "submit" or the value of 256 or 512 is not written to the applicaton on the server.

Your third suggestion may be the answer, I will take a look.

Many thanks for your help and suggestions.

HI Dave


Thanks for the hints I have my code working thanks to you.


I changed my submit buttons to type "button" and pass the values in to the function that I need to write.


document.getElementById("t1").value = value_in;
alert("Totalizer reset");
document.getElementById("t1").value =0;
Many thanks for your help
