写一个ajax变量txt文件 [英] Writing an ajax variable to txt file

问题描述

我有一个Facebook应用程序codeD的客户端，我想保存标记我的服务器，供以后使用

I have a facebook application coded client side and I want to store the tokens on my server for later use

有一个名为变量'令牌'然后我创建了一个名为苹果的新功能，来写这个变量的JSON格式到一个txt文件

There is a variable called 'token' and I then create a new function called 'apple' to write this variable in a json format to a txt file

$(document).ready(function(){

$("#submit").click(function(){

    //access token stuff
    var token = $("#link_input").val();
    //alert("Got Token: " + token + ". your application token");

    if (token.split('#access_token=')[1]) {
    var token = token.split('#access_token=')[1].split('&')[0];
    //alert(token);



function WriteToFile(apple)
    {
    $.post("save.php",{ 'token': apple },
        function(data){
            alert(data);
        }, "text"
    );
    return false;
    } 

我的PHP文件

My php file

<?php
$thefile = "new.json"; /* Our filename as defined earlier */
$towrite = $_POST["token"]; /* What we'll write to the file */
echo $towrite;
$openedfile = fopen($thefile, "w");
$encoded = json_encode($towrite);
fwrite($openedfile, $encoded);
fclose($openedfile);
return "<br> <br>".$towrite;

?>

但我不能把它写什么

but i cant get it to write anything

推荐答案

目前的情况是，您可以定义JS你的将writeToFile 的功能，但你的从不的调用它。 改变你的JS来是这样的：

As it stands now, you define your WriteToFile function in JS, but you never call it. Change your JS to something like:

$(document).ready(function(){

    $("#submit").click(function(){

        //access token stuff
        var token = $("#link_input").val();
        //alert("Got Token: " + token + ". your application token");

        if (token.split('#access_token=')[1]) {
            var token = token.split('#access_token=')[1].split('&')[0];
            WriteToFile(token);
        }
    }



    function WriteToFile(apple) {
        $.post("save.php",{ 'token': apple },
            function(data){
                alert(data);
            }, "text");
        return false;
    }

};

或者

$(document).ready(function(){

    $("#submit").click(function(){

        //access token stuff
        var token = $("#link_input").val();
        //alert("Got Token: " + token + ". your application token");

        if (token.split('#access_token=')[1]) {
            var token = token.split('#access_token=')[1].split('&')[0];
            $.post("save.php",{ 'token': token }, function(data){
                    alert(data);
                }, "text");
        }
    }

};
