Trigger stuff with the enter key

[Shadowing]

Been reading massive examples on how to do this but for some reason I cant get this to work

anyone know how to make it where when I hit enter on the keyboard it runs function "post_chat"

 

<form>
<button class="post_button" type="button" id="post_button">Send</button>
</form>


$(function(){
    $('button.#post_button').keydown(function(e){
        if (e.keyCode == 13) {

            post_chat();  // function to run after enter is hit        

         return false;
        }
    });
});

Buttons don't trigger key events like an input would. If you want to listen for the enter button being pressed for the whole page then listen on document.documentElement.

 

$(function(){
    $(document.documentElement).keydown(function(e){
        if (e.keyCode == 13) {

            post_chat();  // function to run after enter is hit        

         return false;
        }
    });
});

thanks on the reply Alex

 

guess im confused

 

also i dont know why im trying to include the button on it. I'm not trying to get enter to hit the button. im trying to get enter to run the function.

 

I tried your example with no luck

Do you have the function post_chat()? I've tried the example and it works.

 

For example try this:

 

$(function(){
    $(document.documentElement).keydown(function(e){
        if (e.keyCode == 13) {

            alert('it works!');    

         return false;
        }
    });
});

 

And press enter on the page.
