jQuery press button as enter on a text field
提问by Perocat
I have this text field:
我有这个文本字段：
<input id="address" type="text" value="">
and this button:
和这个按钮：
<input id="ricerca" type="button" class="enter" value="GO!">
and jQuery:
和 jQuery：
$("#ricerca").click(function(){
var e = jQuery.Event('keypress');
e.which = 13; // #13 = Enter key
$("#address").focus();
$("#address").trigger(e);
});
I want to simulate the "Enter" press INSIDE the #addressfield, by clicking on the #ricercabutton. It is necessary that the cursor is inside the #addressfield when I press the button.
我想#address通过单击#ricerca按钮来模拟在字段内按“Enter” 。#address当我按下按钮时，光标必须在字段内。
Can you please say me where are the errors?
你能告诉我错误在哪里吗？

define what should happen on keypress event for #address. Look at this code. Press enter key from insde the text box and then click on the button, both trigger the keypress event.
定义 .keypress 事件应该发生什么#address。看看这段代码。在文本框中按回车键，然后单击按钮，两者都会触发按键事件。

$(function () {
$('#address').keypress(function (event) {
if (event.which == 13) {
alert("enter pressed");
//return false; only if needed
}
});
$("#ricerca").click(function () {
var e = jQuery.Event('keypress');
e.which = 13; // #13 = Enter key
$("#address").focus();
$("#address").trigger(e);

Use this Jquery code:
使用此 Jquery 代码：
$("#id_of_textbox").keyup(function(event){
if(event.keyCode == 13){
$("#id_of_button").click();
}
});
