如何在jQuery中显示.txt文件 [英] how to display a .txt file in jquery

问题描述

我有一个textarea和这个javascript代码它应该工作，但不是有什么问题吗？如果是这样，那是什么？

  $（'＃text'）。load（http://hokuco.com/test/xe7/user.txt）;   
 < form action =formcode.phpmethod = POST>< textarea name ='field2'placeholder ='Code here'rows =40cols =40id =text>< / textarea>< br />< input type =submitname =submitvalue =Save>< / form>  

$ b

这里是我的php文件，如果好奇的话：

<？phpif（isset（$ _ POST ['field1 ']）&& isset（$ _ POST ['field2']））{$ data = $ _POST ['field1']。 ' - '。 $ _POST ['field2']。 \\\
; $ ret = file_put_contents（'code.txt'，$ data，FILE_APPEND | LOCK_EX）; if（$ ret === false）{die（'写这个文件时出错'）; } else {echo$ ret bytes write to file;

我假定.txt文件不在同一台服务器/域中作为试图加载它的HTML文件？如果你是，那么你应该使用相对URL，即：

  $（'＃text'）。load（xe7 /user.txt）; 
  

请参阅：

I have a textarea and this javascript code It should work but dosen't is there something wrong? If so, what is it?

$('#text').load("http://hokuco.com/test/xe7/user.txt");

<form action="formcode.php" method="POST">
<textarea name='field2' placeholder='Code here' rows ="40" cols="40" id ="text"></textarea>
<br />
<input type="submit" name="submit" value="Save">
</form>

here is my php file if curious:

<?php
if(isset($_POST['field1']) && isset($_POST['field2'])) {
    $data = $_POST['field1'] . '-' . $_POST['field2'] . "\n";
    $ret = file_put_contents('code.txt', $data, FILE_APPEND | LOCK_EX);
    if($ret === false) {
        die('There was an error writing this file');
    }
    else {
        echo "$ret bytes written to file";
    }
}
else {
   die('no post data to process');
}
?>

解决方案

Due to browser security restrictions, most Ajax requests are subject to the same origin policy; the request can not successfully retrieve data from a different domain, subdomain, port, or protocol.

I'm assuming the .txt file is not on the same server/domain as the HTML file that is trying to load it? If you are, then you should use a relative URL, i.e.:

$('#text').load("xe7/user.txt");
