Dojo 学习笔记入门篇 First Dojo Example
作者:
Dojo学习笔记入门篇,第一个小例子, 刚开始学习dojo的朋友可以参考下。
Step 1: Configurate Dojo
从http://www.dojotoolkit.org/downloads 下载最新的Dojo包,并且放到你工程的某一个地方。比如,我就放把我的dojo库放在lib文件夹下(如图一)。
图一(文件目录结构)
在你的页面中加入如下代码,那么就完成了最基本的配置。
<script type="text/javascript" src="lib/dojo/dojo/dojo.js" djConfig ="parseOnLoad:true, isDebug:false"></script>
Step 2: Start your First Example
我的第一个例子是模拟一个简单的登录页面,如果成功,则显示“Right!”,反之则显示“Wrong!Please try it again!”

var formSubmit = function(e){
e.preventDefault();
var resultText = dojo.byId("resultText");
dojo.xhrPost({

form:"mainForm",
handleAs:"text",
handle:function(data,args){
console.info(data);
if(typeof data=="error"){
resultText.innerHTML = "<font color=\"red\">error!</font>";
}else{
if(data === "right"){
resultText.innerHTML = "Right!";
}else if(data==="wrong"){

});
};
dojo.addOnLoad(function(){
var theForm = dojo.byId("mainForm");
dojo.connect(theForm,"onsubmit","formSubmit");
});
// --></script>
</body>
</html>
(对于其中的Dojo方法,可以查看Dojo的API,在此不再赘述)
后台采用php,代码如下:
<?php
if($_POST["name"] == "blithe" && $_POST["password"]=="blithe"){
print "right";
}else{
print "wrong";
}
?>
