问题：
我有一个用JSON编码的变量，我一直在想如何使用jQuery/AAJAX将这个变量发送到PHP页面。
这就是我迄今为止所尝试的。
- 文件上载使用http://blueimp.github.io/jQuery-File-Upload/
- 它由jQuery根据下面的JS代码进行处理
JS代码：
<script>
$(function () {
'use strict';
// Server-side upload handler:
var url = 'process.php';
$('#fileupload').fileupload({
url: url,
autoUpload: true,
acceptFileTypes: /('.|'/)(txt)$/i,
maxFileSize: 5000000, // 5 MB
done: function (e, data) {
setTimeout(function(){
$("#loading").html("Loading...");}, 1000);
var formUrl = 'exec.php',
// You'll have to re-encode to JSON, probably:
formPerspective = JSON.stringify(data.result.formPerspective),
// This is the newly added value ( Maybe this needs JSON aswell? )
formTxtfile = JSON.stringify(data.result.formTxtfile),
// Generate the form
$form = $('<form action="'+ formUrl +'" method="post"></form>')
.append('<input type="hidden" name="Perspective" value="' + formPerspective + '">')
.append('<input type="hidden" name="Datafile" value="' + formTxtfile + '">')
.append('<input type="hidden" name="form_submitted">');
// Submit the form
$form.submit();
},
progressall: function (e, data) {
var progress = parseInt(data.loaded / data.total * 100, 10);
$('#progress .progress-bar').css(
'width',
progress + '%'
);
}
}).prop('disabled', !$.support.fileInput)
.parent().addClass($.support.fileInput ? undefined : 'disabled');
});
</script>
- 正如您所看到的，它根据下面的代码调用PHP处理程序
PHP代码：
<?php
session_start();
$folder = 'upload';
if (!empty($_FILES))
{
// Set temporary name
$tmp = $_FILES['files']['tmp_name'];
// Set target path and file name
$target = $folder . '/' . $_FILES['files']['name'];
// Upload file to target folder
$status = move_uploaded_file($tmp, $target);
if ($status)
{
// Set session with txtfile name
$_SESSION['txtfile'] = $_FILES['files']['name'];
$text_file = file('upload/' . $_SESSION['txtfile']);
foreach ($text_file as $line_number => $line)
{
if (strpos($line, "'t") === 0)
{
// Remove commented column names and first 't
$dimensions = explode("'t", preg_replace("#'t/.+#", '', substr($line, 1)));
}
}
// Set dimensions
$_SESSION['dimensions'] = str_replace(''n', '', $dimensions);
$jsonReturn = array(
'formPerspective' => $_SESSION['dimensions'],
'formTxtfile' => $_SESSION['txtfile']
);
// Convert to JSON
$encode = json_encode($jsonReturn);
echo $encode;
}
}
?>
所需解决方案：
我想获取$encode中的信息，并使用POST将其发送到页面"oe.lc"。在oe.lc上，使用选择变量
$_POST["Perspective"]
此外，OE.lc会检查表单是否使用提交
$_POST["form_submitted"]
JS应该在提交后重定向到OE.lc（现在它重定向到explorer.php）
有什么想法吗？
尝试简单地回显$encode，然后使用die(); 退出脚本
编辑：您说过要在表单中添加额外的值，首先需要更改php文件，该文件决定返回JSON:中的Javascript
$jsonReturn = array(
'formPerspective' => $dimensions,
'formTxtfile' => $_SESSION['txtfile'],
);
// Convert to JSON
$encode = str_replace(''n', '', json_encode($jsonReturn));
// The above will print out the following when echoed:
// {'formPerspective':["legs","skincover","weight","intelligence","speed"], 'formTxtfile': 'Not sure what this holds as data'}
die($encode);
然后，数据应该在您配置的done回调中的data.result中。
你可能想把浏览器转发到oe.lc，你生成一个表单并提交怎么样？
编辑：我们应该在此处添加新累积的值：
$('#fileupload').fileupload({
// ...
done: function (e, data) {
// Determine the url:
var formUrl = 'http://oe.lc',
// You'll have to re-encode to JSON, probably:
formPerspective = JSON.stringify(data.result.formPerspective),
// This is the newly added value ( Maybe this needs JSON aswell? )
formTxtfile = JSON.stringify(data.result.formTxtfile),
// Generate the form
$form = $("<form action='"+ formUrl +"' method='post'></form>")
.append("<input type='hidden' name='Perspective' value='" + formPerspective + "'>")
.append("<input type='hidden' name='Datafile' value='" + formTxtfile + "'>")
.append("<input type='hidden' name='form_submitted'>")
.appendTo('body');
// Submit the form
$form.submit();
},
// ...
});
如果这对你有用，请告诉我！
以下是完整的代码（但在Firefox中不起作用）：
<script>
$(function () {
'use strict';
// Server-side PHP upload handler
var url = 'process.php';
// File upload handler
$('#fileupload').fileupload({
url: url,
dataType: 'json',
autoUpload: true,
acceptFileTypes: /('.|'/)(txt)$/i,
maxFileSize: 5000000, // 5 MB
done: function (e, data) {
// Output alert message
setTimeout(function(){
$("#loading").html("Loading...");}, 1000);
// Form destination
var formUrl = 'test.php',
// Variables to be sent with the form
formPerspective = data.result.formPerspective,
formTxtfile = data.result.formTxtfile,
// Generate the form
$form = $("<form action='"+ formUrl +"' method='post'></form>")
.append("<input type='hidden' name='Perspective' value='" + formPerspective + "'>")
.append("<input type='hidden' name='Datafile' value='" + formTxtfile + "'>")
.append("<input type='hidden' name='form_submitted' value='true'>")
.appendTo('body');
// Submit the form
$form.submit();
},
// Progress indicator
progressall: function (e, data) {
var progress = parseInt(data.loaded / data.total * 100, 10);
$('#progress .progress-bar').css(
'width',
progress + '%'
);
}
}).prop('disabled', !$.support.fileInput)
.parent().addClass($.support.fileInput ? undefined : 'disabled');
});
</script>
