項目模塊擴展團隊不同，採用框架不同，前臺有prototype轉爲jQuery，下示記錄ajax調用區分

new Ajax.Request(

{
parameters: "para1=val1¶2=val2",
method:'post',
onComplete:function(transport){
alert("er");
var valReturned = transport.responseText;
alert("value returned from server port is " + valReturned);
}
}
);
}
function callServletByJQueryAjax(){
jQuery.ajax({
type:"post",
url:"test1.jQuery?para1=value1",
dataType:"text",
success:function(data){
alert("value returned from sever is : " + data );
}
});
}

<body>
<!--<form action=".do" method="get">-->
<form name="formRequest" action=".do" method="post">
<input type="text" name="form1Para1" value="value1"/>
<input type="submit" value="submit to show page"/>
</form>
<form name="prototypeAjaxRequest">
<input type="button" value="call servlet by prototype Ajax" οnclick="callServletByPrototypeAjax();"/>
</form>
<form name="JQueryAjax">
<input type="button" id="callJQueryAjax" value="call servlet by JQuery Ajax" οnclick="callServletByJQueryAjax();"/></form>
</body>
</html>
當然，在使用jQuery時，可以使用如下方式給組件註冊相關事件。需要注意prototype和jQuery對$符的衝突。
$(document).ready(function(){
$("#callJQueryAjax").click(function(){
jQuery.ajax({
type:"post",
url:"test1.jQuery?para1=value1",
dataType:"text",
success:function(data){
alert("value returned from sever is : " + data );
}
});
});
};
上述Ajax申請資源爲普通servlet，web.xml簡要配置如下，亦可在servlet3.0下使用註解方式。
<servlet>
<servlet-name>test1</servlet-name>
<servlet-class>com.test.Test1OfPrototype</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>test1</servlet-name>
<url-pattern>/test1.prototype</url-pattern>
</servlet-mapping>
<servlet>
<servlet-name>test1JQuery</servlet-name>
<servlet-class>com.test.Test1OfJQuery</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>test1JQuery</servlet-name>
<url-pattern>/test1.jQuery</url-pattern>
</servlet-mapping>
