validate and submit form when enter is pressed in input(textbox) field but does not select history when enter pressed

Question

similar to how we have onfocus and onclick on input tags I am using the below method( if the method is wrong please let me know what would be the proper method ) for submitting a form when someone presses enter on a textbox in a field in a form

Example when someone writes the password in the password field and presses enter (when the cursor is on the password field) the form should submit.

I even have a submit button but I want the same thing to happen when text has enter pressed when submit is clicked

I am using this right now

onkeypress='if (event.keyCode == 13) { validate(); }'

for my textbox fields

the issue over here is that when the history of my text box shows below my text box and I select it by pressing enter it does not take the value first in my text box. It straight away validates the value in the text box

Example: I have typed abcin my email textbox, I get abc@xyz.com below my text box showing that I had typed that earlier, not when I do down by pressing the down arrow and pressing enter it does not take abc@xyz.com in my text box but straight away runs validate() anhd gives me an error as wrong email format.

I believe it should first take my old value in the text box and then run the validate function

I am using codeigniter

Not sure to have understood your question,
maybe you need a code like this:

function submitMe(event) {
    if (window.event.keyCode == 13)
    {
        document.myForm.submit();
    }
}

Then in your HTML:

 <input type="input" ... onKeyPress="submitMe(event)"  value=""> 

or you can use autocomplete="off" instead of value=""

 <input type="input" ... onKeyPress="submitMe(event)"  autocomplete="off">
