So here's my issue, I am using AJAX (jQuery) to post a form to process.php
but the page actually needs to echo out a response such as apple
or plum
. I'm not sure how to take the response from process.php
and have it stored as a variable...
这是我的问题,我正在使用AJAX (jQuery)来发布一个要处理的表单。但是页面实际上需要响应,比如apple或plum。我不知道如何从过程中得到响应。把它存储为变量…
Here's the code I have so far:
这是我迄今为止的代码:
<script type="text/javascript">
function returnwasset(){
alert('return sent');
$.ajax({
type: "POST",
url: "process.php",
data: somedata;
success function(){
//echo what the server sent back...
}
});
}
</script>
Also will I need to echo the response in process.php
in json? or will plain text be fine?
我还需要在过程中对响应进行响应。php在json吗?或者纯文本也可以吗?
Sorry if this sounds like a stupid question, this is my first time doing something as such in Ajax.
抱歉,如果这听起来像一个愚蠢的问题,这是我第一次在Ajax中做类似的事情。
PS: How do I name the POST request in the above code?
PS:如何在上面的代码中命名POST请求?

<?php echo 'apple'; ?>
is pretty much literally all you need on the server.
< ?php echo '苹果';>基本上就是你在服务器上所需要的一切。
as for the JS side, the output of the server-side script is passed as a parameter to the success handler function, so you'd have
对于JS方面,服务器端脚本的输出作为一个参数传递给成功处理程序函数,所以您会得到。
success: function(data) {
alert(data); // apple
}

好的做法是这样使用:
$.ajax({

url: "/ajax/request.html",
data: {action: 'test'},
dataType:'JSON',
success: function(response){
console.log(response.blablabla);
// put on console what server sent back...

in your PHP file, when you echo your data use json_encode (http://php.net/manual/en/function.json-encode.php)
在PHP文件中,当你使用json_encode (http://php.net/manual/en/function.json-encode.php)来回传你的数据时。
e.g.
如。
<?php
//plum or data...
$output = array("data","plum");
echo json_encode($output);
?>
in your javascript code, when your ajax completes the json encoded response data can be turned into an js array like this:
在javascript代码中,当ajax完成json编码的响应数据时,可以将其转换为如下所示的js数组:
$.ajax({
type: "POST",
url: "process.php",
data: somedata;
success function(json_data){
var data_array = $.parseJSON(json_data);
//access your data like this:
var plum_or_whatever = data_array['output'];.
//continue from here...
}
