问题描述

我使用一个按钮提交表单，而不是一个提交按钮。不过，我的问题是，我当我preSS进，形式不不会提交，所以不是我实际上是点击提交按钮，它可以是不方便。我想知道我怎么可以用一个按钮从提交我而无需刷新页面，当我preSS进入，也有形式提交。我觉得这是一个非常简单的解决方法，我只是找不到。这里是URL以在其上发生问题的页面。

I am using a button to submit a form, not a submit button. However, my problem is that I when I press enter, the form does not not submit, so instead i actually have to click the submit button, which can be inconvenient. I am wondering how I can use a button the submit my from without having the page refresh and when I press enter, also have the form submit. I feel like it is a very easy fix that I just can not find. Here is the URL to the page on which the problem is occurring. http://www.pearlsquirrel.com/register.php

下面是code到register.php

Here is the code to register.php

<div id="centered3">
<h1><div align='center' style="color:white;">Join PearlSquirrel</align></h1>
<h4><div id='response'></div></h4>
<script language='javascript' type='text/javascript'>
function ajaxregister(){
var ajaxRequest;

try{
    // Opera 8.0+, Firefox, Safari
    ajaxRequest = new XMLHttpRequest();
} catch (e){
    // Internet Explorer Browsers
    try{
        ajaxRequest = new ActiveXObject('Msxml2.XMLHTTP');
    } catch (e) {
        try{
            ajaxRequest = new ActiveXObject('Microsoft.XMLHTTP');
        } catch (e){
            // Something went wrong
            alert('Your browser broke!');
            return false;
        }
    }
}
ajaxRequest.onreadystatechange = function(){
    if(ajaxRequest.readyState == 4){
        var ajaxDisplay = document.getElementById('response');
        ajaxDisplay.innerHTML = ajaxRequest.responseText;

    }
}
var username = document.getElementById('username').value;
var password = document.getElementById('password').value;
var repeatpassword = document.getElementById('repeatpassword').value;
var queryString = '?username=' + username + '&password=' + password +     '&repeatpassword=' + repeatpassword;
ajaxRequest.open('GET', 'ajaxregister.php' + queryString, true);
ajaxRequest.send(null);

}
</script>
<form method='GET'>

        <tr>

$(document).ready(function(){

function username_check(){
var username = $('#username').val();
