AJAX

附件有简单封装的AJAX对象的引用以及请求服务器的方法

 

AJAX后台如何处理response流以供前端使用

int flg = ProductAcceptMaint.checkReference(sReference);
   response.reset();
   java.io.PrintWriter out = response.getWriter();
   response.setContentType("text/html;charset=GBK");
   out.print(flg);

 

不能用out.write,而且注意在此之前response是否有值    //待定

 

//responseText处理

str=str.replace(/^\s+|\s+$/,"");

 

 

AJAX提交对于“%”的处理，escape()

var url = "ReferenceWorkNo?flg=checkWorkNo&workNo="+escape(workNo);
                   // Open a connection to the server
                   xmlHttp.open("GET", url, true);//true is asyn
                   // Setup a function for the server to run when it's done
                   xmlHttp.onreadystatechange = dealWorkNoResult;
                   // Send the request
                   xmlHttp.send(null);

var xmlDoc=xmlHttp.responseXML.documentElement;
xmlDoc.getElementsByTagName("compname")[0].childNodes[0].nodeValue;

 

//2级联动?
