thinkphp 5.0.7. Ajax is used in view to submit post data. After the data is submitted, it cannot be printed through tp.
After studying it for a long time, I really don"t know what went wrong.A very simple test code,
Front end:
<html>
<head>
<title>title</title>
<script src="http://libs.baidu.com/jquery/1.9.0/jquery.min.js"></script>
<script>
$(function(){
$("-sharpbtn").click(function(){
$.ajax({
url:"/Home/test/index",
type: "POST",
dataType:"",
data:{id:3},
//async: false,
success:function(data){
alert(data.id);
}
});
});
});
</script>
</head>
<body>
<input type="button" id="btn" value="button">
</body>
</html>
Server side:
class Test extends Controller {
public function index()
{
$dd["id"] = $_POST["id"];
$dd["value"] = "fff";
print_r(json_encode($dd));
return $this->fetch();
}finally, the page output is:
{"id":null,"value":"fff"} here, the value of the id in the foreground, that is, $_ POST ["id"] is always null,
and the foreground alert (data.id); the content is also undefined.
in the contents of network, you can see the data of post and the success of post, but neither the front-end alert nor the background can get the data of post
?
