我开始学习Ajax并且我做了这个显示用户输入的简单HTML页面,当他输入一本书的名称(存储在php文件中的数组中)时,使用ajax,用户可以在下面看到输入结果,而他类型,这是我无法做到的部分,这是代码:
<!DOCTYPE html>
<html>
<head>
<script type="text/javascript" src="bookstore.js"></script>
<link rel="stylesheet" href="style.css">
</head>
<body onload="process()">
<h1>
Hadhemi's BookStore !
</h1>
Enter the book you want to order
<input type="text" id="userInput">
<div id="underInput"> </div>
</body>
</html>
这是JS文件
// 3 functions : create an object, communicate and response
var xmlHttp=createXmlHttpRequestObject();
function createXmlHttpRequestObject()
{
var xmlHttp;
if(window.ActiveXObject)
{
try
{
xmlHttp = new ActiveXObject("Microsoft.XMLHTTP"); //check for IE
}
catch (e)
{
xmlHttp = false;
}
}
else
{
try
{
xmlHttp = new XMLHttpRequest(); …我尝试更新Android SDK并显示错误:

我需要在MATLAB中为图像实现中值滤波.但是,我不允许在MATLAB中使用medfilt2或ordfilt2函数.我们最近也开始学习MATLAB.
是否有可用于中值滤波器或高斯滤波器的代码？
