看点:
1、file_get_contents超时控制。
2、页面编码判断。
3、键盘Enter键捕捉响应。
4、键盘event兼容处理。//event = event || window.event;
5、XMLHttpRequest 和 jQuery 两种实现方案。
6、页面及源码同时展示。
XMLHttpRequest版本 get_web.php
复制代码 代码如下:
<?php
header("Content-type: text/html; charset=utf-8");
if(!empty($_POST['input_text'])) {
ini_set('default_socket_timeout', 10);
if(!$data = file_get_contents($_POST['input_text'])) {
echo "Time out!";
return ;
}
$charset_pos = stripos($data,'charset');
if($charset_pos) {
if(stripos($data,'utf-8',$charset_pos)) {
echo iconv('utf-8','utf-8',$data);
}else if(stripos($data,'gb2312',$charset_pos)) {
echo iconv('gb2312','utf-8',$data);
}else if(stripos($data,'gbk',$charset_pos)) {
