Hello, Do you have any information on how the AJAX and Wiz550Web interact? I am using your demo pages and editing them but trial and error is a slow proccess. I was hoping that you had some documentation that explains the the interaction. Thanks!

Hi, Thanks for your reply. Since there is no information on how your application works, I was hoping that you could answer a few questions for me? I am having trouble doing things sequentially and I think it is due to timing. When I execute the code pasted below, not all of the I/O change as expected, and I get a debug error in my browser (Chrome) console that says: (index):265 POST 192.168.11.100/dout.cgi net::ERR_CONNECTION_REFUSED AJAX.doPost @ (index):265 (anonymous function) @ (index):390 I was also wondering how I can check the state of a pin, whether or not is is Hi or low? Thanks! function postdataPinState(pinNumber,pinState){ var p=pinNumber; var v = pinState; dout_timer=setTimeout(function(){ if(dout && dout.abort){dout.abort();} dout=new AJAX(‘dout.cgi’,function(t){ try{eval(t);}catch(e){alert(e);} }); dout.doPost(‘pin=’+p+‘&val=’+v); },300); } function postdataPinDir(pinNumber,pinDirection){ var p=pinNumber; var v = pinDirection; dout_timer=setTimeout(function(){ if(dout && dout.abort){dout.abort();} dout=new AJAX(‘dir_change.cgi’,function(t){ try{eval(t);}catch(e){alert(e);console.log(t);} }); dout.doPost(‘pin=’+p+‘&dir=’+v); },300); } function myDelay(myDelayTime){ for(var i=0; i<myDelayTime;){ i++; } } function setAddrToVersion(){ postdataPinState(10,0); postdataPinState(11,0); postdataPinState(12,0); postdataPinState(13,0); } function setDataBusToInput(){ postdataPinDir(0,1); myDelay(1000); postdataPinDir(1,1); myDelay(1000); postdataPinDir(2,1); myDelay(1000); postdataPinDir(3,1); myDelay(1000); postdataPinDir(4,1); myDelay(1000); postdataPinDir(5,1); myDelay(1000); postdataPinDir(6,1); myDelay(1000); postdataPinDir(7,1); } function setDataBusToOutput(){ postdataPinDir(0,2); myDelay(1000); postdataPinDir(1,2); myDelay(1000); postdataPinDir(2,2); myDelay(1000); postdataPinDir(3,2); myDelay(1000); postdataPinDir(4,2); myDelay(1000); postdataPinDir(5,2); myDelay(1000); postdataPinDir(6,2); myDelay(1000); postdataPinDir(7,2); } function…

Hi, I would also like to know how to read the status of an actual pin without having to check the html alias/name. Thanks!

Nevermind… as if you were actually working on it. There are two ways to do what I wanted. use JQuery and the when() then() methods simply make ajax synchronus (this is what I used) function AJAX(url, callback) { var req = AJAX_init(); req.onreadystatechange = AJAX_processRequest; function AJAX_init() { if (window.XMLHttpRequest) { return new XMLHttpRequest(); } else if (window.ActiveXObject) { return new ActiveXObject('Microsoft.XMLHTTP'); } }; function AJAX_processRequest() { if(req.readyState == 4) { if(req.status == 200) { if(callback) callback(req.responseText); } } }; this.doGet = function() { req.open('GET', url, false); // set this to false for synchronous behavior req.send(null); }; this.doPost = function(body) { req.open('POST', url, false); // set this to false for synchronous behavior req.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded'); req.setRequestHeader('ISAJAX','yes'); req.send(body); }; };
