我有一个基本表单,我提交了一个facebook朋友的ID,php返回我的名字,我的FB照片,我朋友的名字和我朋友的fb照片。这是我的相关代码
HTML
<form name="input">
<input type="text" name="name" id="name"/>
<input id="submit" type="submit" class="btn btn-info" value="Submit"/>
</form>
<div class="row" id="graphArea"></div>
JAVASCRIPT
$('#submit').click(function(e){
e.preventDefault();
var formData = $('form').serialize();
submitForm(formData);
});
function submitForm(formData){
$.ajax({
type: 'POST',
url: 'graph.php',
data: formData,
dataType: 'json',
cache: false,
timeout: 7000,
success: function(data) {
$("#graphArea").load("graph.php");
$(window).scrollTop($("#graphArea").offset().top);
$("#graphArea").fadeIn(500);
},
error: function(XMLHttpRequest, textStatus, errorThrown) {
alert("There was an error");
},
complete: function(XMLHttpRequest, status) {
$('form')[0].reset();
}
});
graph.php
<?php
require 'resources/plugin/facebook-php-sdk/src/facebook.php';
//..some facebook authentication stuff
$friend = $_POST['name'];
$basicInfo = $fb->api('me?fields=friends.uid(' . $friend . ').fields(first_name,name),first_name,name');
?>
<hr>
<br />
<div class="span2 offset2"><h3>
<?php
echo $basicInfo['name'] . "</h3></div><div class=\"span2\">";
echo "<img src='https://graph.facebook.com/" . $user . "/picture?type=large'>";
echo "</div><div class=\"span2\">";
echo "<img src='https://graph.facebook.com/" . $friend . "/picture?type=large'></div>";
echo "<div class=\"span2\"><h3>" . $basicInfo['friends']['data'][0]['name'];
?>
</h3>
</div>
每当我提交表单时,我都会收到错误部分,警告“发生了错误”。然而,通过Google Chrome Javascript控制台查看,然后点击网络然后预览,我看到了我想要的结果!这是我第一次处理PHP和AJAX,我很感激能得到的所有帮助。谢谢!
答案 0 :(得分:2)
在您的javascript ajax调用中,您将dataType: 'json',
称为php
,而html
将返回html
,这将引发错误。如果您希望响应位于html中,请将数据类型更改为{{1}}。
答案 1 :(得分:1)
您对graph.php
的ajax调用包括dataType: 'json'
,但graph.php
似乎会输出HTML片段。此外,您的AJAX成功处理程序再次调用graph.php
- 这是不必要的,因为您刚刚调用graph.php
来提交表单。您应该取回返回的HTML并将其注入DOM:
$.ajax({
type: 'POST',
url: 'graph.php',
data: formData,
// REMOVED dataType
cache: false,
timeout: 7000,
success: function(data) {
$("#graphArea").html(data); // CHANGED
$(window).scrollTop($("#graphArea").offset().top);
$("#graphArea").fadeIn(500);
},
error: function(XMLHttpRequest, textStatus, errorThrown) {
alert("There was an error");
},
complete: function(XMLHttpRequest, status) {
$('form')[0].reset();
}
});
