How can I combine 2 or more jquery keydown functions into one function?
Question by Pachonk
My goal:
To clean up multiple keydown functions leading to the same button press by making it one function.
My issue:
I have made many functions like this:
$("#username").keydown(function(event){
if(event.keyCode == 13) {
$('#loginbtn').click();
};
});
$("#password").keydown(function(event){
if(event.keyCode == 13) {
$('#loginbtn').click();
};
});
That trigger button clicks on buttons. It is too messy and uses many lines. I want to combine the lines into one function. I have many boxes for my registration form as well.
What have I tried?
1.
I have tried the following code bellow and other replications which do not work:
$("#username","#password").keydown(function(event){
if(event.keyCode == 13) {
$('#loginbtn').click();
};
});
2.
Another idea I had was to use a class, I just don’t know if this is considered the “proper” way to do it, so I need opinions:
$(".logintextbox").keydown(function(event){
if(event.keyCode == 13) {
$('#loginbtn').click();
};
});
Then I would also add that class in my html so all of the login text boxes and all of the register text boxes have unique classes “grouping” them.
My question/tl;dr:
How can I combine 2 or more jquery keydown functions into one function using multiple id’s or one class?

I suggest delegating from your form instead of individual elements.
$("#your_form_id").on('keydown', 'input', function(event){
if(event.keyCode == 13) {
$('#loginbtn').click();
};
});
This will capture the key being pressed on all inputs within your form.
