How do I use the Enter key as an event handler (javascript)?
im trying to make my own chat... so i have an input text field, the submit button, isn't even submit, its just a button.... so when the enter key is pressed, i need the value of the input field to appear in my textarea (which is readonly)...
well look.. make long story short, i just want a basic enter key event handler, i know it works perfectly with submit buttons cus you don't need to program anything at all, its default. but my button is type="button" .... so when you press enter nothing happens... how do i trigger my button by pressing enter?
You could make the burron type submit, or you can use the onkeyup event handler and check for keycode 13 (http://www.cambiaresearch.com/c4/702b8cd1-e5b0-42e6-83ac-25f0306e3e25/Javascript-Char-Codes-Key-Codes.aspx has a list of key codes). You'll have to know how to get the keycode from the event.
edit: an example
HTML:
<input onkeyup="inputKeyUp(event)" ...>
Plain javascript:
function inputKeyUp(e) {
e.which = e.which || e.keyCode;
if(e.which == 13) {
// submit
}
}
以下是用于侦听输入密钥的工作代码片段
$(document).ready(function(){
$(document).bind('keypress',pressed);
});
function pressed(e)
{
if(e.keyCode === 13)
{
alert('enter pressed');
//put button.click() here
}
}
