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").childNodes.nodeValue;
//2级联动?
