我的解决方案是使用 onClick 事件调用 PHP 页面、发布参数并使用 AJAX 返回结果。我在使用指定 URL 调用 PHP 页面时插入参数。这是我的Javascript:
function uploadContact() {
var name, email, phone, badgeid;
if(window.localStorage.length > 0)
{
name = window.localStorage.getItem('name');
email = window.localStorage.getItem('email');
phone = window.localStorage.getItem('phone');
}
else
{
name = $('input[name=fullname]').val();
email = $('input[name=email]').val();
phone = $('input[name=phone]').val();
}
$.ajax({
url: 'UpdateContactList.php?name=' + name + '&email=' + email + '&phone=' + phone,
type: $form.attr('method'),
dataType: 'json',
success: function(responseJson) {
$form.before("<p>"+responseJson.message+"</p>");
},
error: function() {
$form.before("<p>There was an error processing your request.</p>");
}});
}
我获取参数的 PHP 代码:
<?php
$response = array();
if($_SERVER['REQUEST_METHOD'] == 'POST')
{
// if form has been posted process data
// you dont need the addContact function you jsut need to put it in a new array
// and it doesnt make sense in this context so jsut do it here
// then used json_decode and json_decode to read/save your json in
// saveContact()
$data = array( 'fullname' => $_POST['name'], 'email' => $_POST['email'], 'phone' => $_POST['phone']);
//These line is for testing only, remove it when done testing
$test = $_POST['name'] . ' ' . $_POST['email'];
echo "<script>alert('$test');</script>";
// always return true if you save the contact data ok or false if it fails
$response['status'] = updateContact($data) ? 'success' : 'error';
$response['message'] = $response['status']
? 'Your submission has been saved!'
: 'There was a problem saving your submission.';
header("Content-type: application/json");
echo json_encode($response);
exit;
}
...
function updateCacheFile($filename)
{
$filename = "contact";
$filename = $filename . ".appcache";
$cachefile = fopen ($filename, "a+");
....
file_put_contents($filename, $cache_content);
}
请注意2个问题:
我可以使用浏览地址链接中的参数直接调用 PHP 页面,这样做不会返回任何内容。正常吗?
从 JavaScript 调用。测试线(调用警告消息框)不起作用,没有消息出现。但是缓存文件仍然更新,这意味着 PHP 页面被调用并执行诸如写入文件之类的操作。
此 PHP 页面中有 2 个文件要写入。两者都正确写入,但参数不会显示,也不会显示消息框。
请告诉我这里出了什么问题。
P/S:小细节,带空格的参数可以正确传递吗?因为我希望用户输入他们的全名,例如“Bill Jobs”。
