jQuery模拟输入的按键

Question

I tried the answer here but it doesn't work for me.

JSFiddle: https://jsfiddle.net/Ldu6wwv0/

$('input').val('test').trigger(jQuery.Event('keypress', {keycode: 13}));

$('input').on('keypress', function(){
    $('p').text("worked");
});

What am I doing wrong?

Answer 1

The problem seems to be order of your code. Your code which triggers keypress is defined before the event handler.

This seems to work now. ( JSFiddle )

$('input').on('keypress', function(){
    $('p').text("worked");
});

$('input').val('test').trigger(jQuery.Event('keypress', {keycode: 13}));

UPDATE: Also Please don't use keycode as it is deprecated ( link ) and might not work in some cases. I've personally faced this issue. Use which instead.

JSFiddle

$('input').on('keypress', function(){
    $('p').text("worked");
});

var e = jQuery.Event("keypress");
e.which = 13;
$("input").focus().val('test').trigger(e);
