zilav Posted August 2, 2014 Share Posted August 2, 2014 Define some function in javascript which will accept a sting (for example in some external js file linked by ServerModule.CustomFiles) function myfunc(s) { ... } When you need some response from server, call uni's ajaxEvent() function from your client js code, on server side in OnAjaxEvent UniSession.AddJS('myfunc(' + StringToReturn + ');'; Your function will be called with passed string as soon as response reaches client. Check ajax event demos that come with UniGUI. Link to comment Share on other sites More sharing options...

wangxuebin Posted August 4, 2014 Share Posted August 4, 2014 An example: <html> <head> <title>FCKeditor - Sample</title> <script type="text/javascript"> var xmlHttp,editortxt; function saveeditor() { xmlHttp=GetXmlHttpObject(); if (xmlHttp==null) { alert ("Browser does not support HTTP Request") return; } var url="phps/phpinfo1.php"; editortxt=document.getElementById("content21").value; editortxt="name="+editortxt; //alert(editortxt); editortxt=encodeURI(editortxt); //url=url+"?q="+editortxt; //url=url+"&sid="+Math.random(); xmlHttp.onreadystatechange=stateChanged; xmlHttp.open("POST",url,true); xmlHttp.setRequestHeader("Content-Type","application/x-www-form-urlencoded"); xmlHttp.send(editortxt); } function dodo(){ if(xmlHttp.readyState==4){ // xmlHttp下的readystate方法 4表示传送完毕 if(xmlHttp.status==200){ // xmlHttp的status方法读取状态(服务器HTTP状态码) 200对应OK 404对应Not Found(未找到)等 document.getElementById("content").innerHTML=xmlHttp.responseText //xmlHttp的responseText方法 得到读取页数据 } } } function stateChanged() { if (xmlHttp.readyState==4 || xmlHttp.readyState=="complete") { document.getElementById('A4').innerHTML=xmlHttp.responseText; //document.getElementById('content21').innerHTML=xmlHttp.responseText; alert(xmlHttp.responseText+'<br>状态:'+xmlHttp.statusText); // alert(xmlHttp.statusText); } } function GetXmlHttpObject() { var xmlHttp=null; try { // Firefox, Opera 8.0+, Safari xmlHttp=new XMLHttpRequest(); } catch (e) { //Internet Explorer try { xmlHttp=new ActiveXObject("Msxml2.XMLHTTP"); } catch (e) { xmlHttp=new ActiveXObject("Microsoft.XMLHTTP"); } } return xmlHttp; } </script> </head> <body> <form action="javascript:saveeditor();" method="post"> <div> <textarea name="content21" id="content21" resizable=yes></textarea> </div> <p><b>Response:</b> <br /><span id="A4"></span> </p> <input type="submit" value="提交" /> </form> </body> </html> 1 Link to comment Share on other sites More sharing options...
