JQuery simulating keypress event on an input field
提问by Masiar
I have an input field which is dynamically filled with some AJAX, and once it's filled I would like to have JavaScript to automatically press "Enter" (key event 13) on that input inducing another function, which is hidden to me, to trigger.
我有一个输入字段，它用一些 AJAX 动态填充，一旦它被填充，我想让 JavaScript 在该输入上自动按下“Enter”（键事件 13），从而引发另一个对我隐藏的函数来触发。
Would it be possible with jQuery? I have this code right now, which is not working:
用jQuery可以吗？我现在有这个代码，但它不起作用：
$('#myInputId').focus().trigger({ type : 'keypress', which : 13 });
$('#myInputId').focus().trigger({ type : 'keypress', which : 13 });
Do you have any clue on what am I doing wrong?
你对我做错了什么有任何线索吗？
Thanks,
谢谢，

You can create an event object:
您可以创建一个 事件对象：
$('#myInputId').trigger(jQuery.Event('keypress', { keycode: 13 }));

Hi you could try use the change event for when the input area changes :
嗨，您可以尝试在输入区域更改时使用更改事件：
$('#myInputId').change(function(){
$('#myInputId').focus().trigger({ type : 'keypress', which : 13 });
});

On Keypress Enter:
在按键上Enter：
$(document).keypress(function(event){
var keycode = (event.keyCode ? event.keyCode : event.which);
if(keycode == '13'){
alert('You pressed a "enter" key in somewhere');
}
});
