The same source code can be run locally and cannot be executed on the server. Solution

The same source code can be run locally and cannot be executed on the server. I wrote an ajax request. I tested it locally, but I couldn't execute it on the server. Why? You have never had this situation. AjaxJScriptcodefunctionshowList (id) {urlajaxlist. php; $. get (url, {id: id}, with the same source code as funct, which can be locally executed and cannot be executed on the server.

You have never had this situation.

Ajax

JScript code

  Function showList (id) {url = 'ajaxlist. php '; $. get (url, {id: id}, function (e) {if (e = 0) {$ ("# info" ).html ("No payment information ");} else {$ ("# info" ).html (e );}});}

PHP code

  
  Db_Query($sql);$row=$news->Db_Fetch_Array();if($row){    echo json_decode($row['paytype']);}else{    die(0);}?>

Server:



------ Solution --------------------
First, check whether the server supports json. should json_encode be used?
------ Solution --------------------
Is the database matched? what is the table name of the user name and password?
------ Solution --------------------
Url = 'ajaxlist. php'; the path is incorrect. Try it with absolute
------ Solution --------------------
Use var_dump to output background data and firebug to check whether the data format passed in the background is correct. Is it a traditional ajax problem such as bom header and encoding?

Use var_dump to output background data and firebug to check whether the data format passed in the background is correct. Is it a traditional ajax problem such as bom header and encoding?

------ Solution --------------------
$. Get (url, {id: id },
Function (e ){
If (e = 0 ){
$ ("# Info" ).html ("No payment information ");
} Else {
$ ("# Info" ).html (e );
}
}); Is your get method type supposed to be json transfer.
------ Solution --------------------
$. Get (url, {id: id },???
$. Get (url, {'id': id },
I wonder if I have a mistake

Run the server program separately to check whether the returned results are normal.
