这是我的代码......
如何将文本框数组值存储在数据库中...
<html>
<head>
<script type="text/javascript">
var max = 4; //highest number to go to
var currentIndex = 0;
function btnClick() {
if(currentIndex < max){
currentIndex++;
postClick();
}
}
function Previous(){
if(currentIndex>0){
currentIndex--;
postClick();
}
}
function postClick() {//whatever you want to happen goes here
var sahans = new Array();
sahans[currentIndex] == d;
var d = document.getElementById("div");
d.innerHTML = "<p><input type='text' name='name"+currentIndex+"[]'>";
d.innerHTML += "<p><input type='text' name='topic"+currentIndex+"[]'>";
document.getElementById("div").style.display = "";
}
</script>
</head>
<body>
<form id="form1">
<div>
<input type="button" value="Previous" onclick="Previous();" />
<input type="button" value="Next" onclick="btnClick();" />
<div id="div"></div>
</div>
</form>
</body>
</html>

<强> JavaScript的：
function store(form) {
var input = form.getElementsByTagName('input');
var myarray = Array();
for (var i = 0; i < input.length; i++) {
if (input[i].getAttribute('type') == 'text') {
myarray[input[i].getAttribute('name')] = input[i].value;
}
}
for (var i in myarray) {
alert(i + ': ' + myarray[i]);
}
}
<强> HTML：
<form onsubmit="store(this); return false">
<p>
<input type="text" name="name" /><br />
<input type="text" name="topic" />
</p>
<p>
<input type="submit" value="Store in database" />
</p>
</form>

好的，现在我用AJAX和实际保存到数据库做了一个完整的例子。 AJAX调用使用'POST'。只需在max变量中填写所需的字段数。
<强> JavaScript的：
var max = 10;
var current = 0;
function goto(form, pos) {
current += pos;
form.prev.disabled = current <= 0;
form.next.disabled = current >= max - 1;
var fields = form.getElementsByTagName('fieldset');
for (var i = 0; i < fields.length; i++) fields[i].style.display = 'none';
fields[current].style.display = 'block';
form['name' + current].focus();
}
function store(form) {
var input = form.getElementsByTagName('input');
var data = '';
for (var i = 0; i < input.length; i++) {
if (input[i].getAttribute('type') == 'text')
data += '&' + input[i].getAttribute('name') + '=' + input[i].value;
}
data = encodeURI('n=' + max + data);
var xhr = window.XMLHttpRequest ? new XMLHttpRequest() : new ActiveXObject('Microsoft.XMLHTTP');
xhr.open('POST', 'store.php', true);
xhr.setRequestHeader('Content-type', 'application/x-www-form-urlencoded');
xhr.setRequestHeader('Content-length', data.length);
xhr.setRequestHeader('Connection', 'close');
xhr.onreadystatechange = function() {
if (this.readyState == 4 && this.status == 200) {
if (this.responseText != '')
alert(this.responseText);
else {
form.submit.value = 'Saved!';
setTimeout(function() { form.submit.value = 'Save to database' }, 500);
}
}
}
xhr.send(data);
}
window.onload = function() {
var form = document.forms[0];
var container = form.getElementsByTagName('div')[0];
container.innerHTML = '';
for (var i = 0; i < max; i++)
container.innerHTML += '<fieldset><legend>Entry ' + (i + 1) + ' / ' + max + '</legend><input type="text" name="name' + i + '" /><br /><input type="text" name="topic' + i + '" /></fieldset>';
goto(form, 0);
}
<强> HTML：
<form action="submit.php" method="post" onsubmit="store(this); return false">
<p>
<input type="button" name="prev" onclick="goto(this.form, -1)" value="Previous" />
<input type="button" name="next" onclick="goto(this.form, +1)" value="Next" />
</p>
<div>
<noscript>Please enable JavaScript to see this form correctly.</noscript>
</div>
<p>
<input type="submit" name="submit" value="Store in database" />
</p>
</form>
禁用JS的用户将看到<noscript>标记中的内容，否则将替换为字段集。此外，为已禁用JS的用户创建备用提交页面（submit.php）也很不错。下面是store.php，即AJAX提交脚本。
PHP （store.php）：
<?php
if (empty($_POST['n']) || $_POST['n'] < 1) die('Invalid request!');
$fields = array('name', 'topic');
$errors = '';
for ($i = 0; $i < $_POST['n']; $i++) {
foreach ($fields as $field) {
if (empty($_POST[$field . $i]))
$errors .= '- ' . $field . ' ' . ($i + 1) . "\n";
}
}
if ($errors != '')
die("Please fill in the following fields:\n" . $errors);
$db = mysql_connect('localhost', 'root', '');
mysql_select_db('mydb', $db);
for ($i = 0; $i < $_POST['n']; $i++) {
$name = mysql_real_escape_string($_POST['name' . $i]);
$topic = mysql_real_escape_string($_POST['topic' . $i]);
mysql_query(' INSERT INTO entries (id, name, topic) VALUES (' . $i . ', "' . $name . '", "' . $topic . '")
ON DUPLICATE KEY UPDATE name = "' . $name . '", topic = "' . $topic . '"
') or die('Database error!');
}
mysql_close($db);
?>
此脚本的输出文本（如果有错误）显示在JavaScript alert中。
我希望它现在适合你。

这对你有帮助
<input type="textbox" name="Tue[]" />
<input type="textbox" name="Tue[]" />
<input type="textbox" name="Tue[]" />
<input type="textbox" name="Tue[]" />
<script type="text/javascript">
function validateText(event){
var tar_ele = $(event.target);
if(tar_ele.val() is not valid)
tar_ele.focus();
}
</script>
<input type="text" name="Tue[]" onblur="validateText(event)"/>
javascript text box array and get values and focus on particular field
