Hello, I have this script; <html> <head> <script type="text/JavaScript" language="JavaScript"> var xmlHttp=false; try { xmlHttp = new ActiveXObject("Msxml2.xmlHttp"); } catch (e) { try { xmlHttp = new ActiveXObject("Microsoft.xmlHttp"); } catch (E) { xmlHttp = false; } } if (!xmlHttp && typeof XMLHttpRequest!='undefined') { try { xmlHttp = new XMLHttpRequest(); } catch (e) { xmlHttp=false; } } if (!xmlHttp && window.createRequest) { try { xmlHttp = window.createRequest(); } catch (e) { xmlHttp=false; } } function callServer(){ //burada çağiracağin sayfayı yazarsın var url = "xml.php"; xmlHttp.open("GET", url, true); xmlHttp.onreadystatechange = updatePage;{ if (xmlHttp.readyState==4) { alert(xmlHttp.responseText) } } xmlHttp.send(null) } function updatePage(){ //4 sorun yoksa demek if(xmlHttp.readyState == 4){ //gelen cevap var response = xmlHttp.responseText; //hangi div gelcekse buraya yazılcak TICKER.innerHTML = response; //500 milisaniyede bir fonksiyonu cağirir setTimeout('callServer()',5000); } } callServer('url'); </script> </head> <div STYLE="display:none; border-top:1px solid #CCCCCC; border-bottom:1px solid #CCCCCC; overflow:hidden; background-color:#FFFFFF; width:620px" onmouseover="TICKER_PAUSED=true" onmouseout="TICKER_PAUSED=false" id="TICKER">DSADADA</div> <script type="text/javascript" src="webticker_lib.js" language="javascript"></script> </html> Code (markup): When TICKER DIV is updated, the news bar starts not ticking in Firefox. In Internet Explorer, TICKER DIV is sometimes updating, sometimes not. How can we fix this problem? Thank you,
Also, this is the content of webticker_lib.js; TICKER_CONTENT = document.getElementById("TICKER").innerHTML; TICKER_RIGHTTOLEFT = false; TICKER_SPEED = 2; TICKER_STYLE = "font-family:Arial; font-size:12px; color:#444444"; TICKER_PAUSED = false; ticker_start(); function ticker_start() { var tickerSupported = false; TICKER_WIDTH = document.getElementById("TICKER").style.width; var img = "<img src=ticker_space.gif width="+TICKER_WIDTH+" height=0>"; // Firefox if (navigator.userAgent.indexOf("Firefox")!=-1 || navigator.userAgent.indexOf("Safari")!=-1) { document.getElementById("TICKER").innerHTML = "<TABLE cellspacing='0' cellpadding='0' width='100%'><TR><TD nowrap='nowrap'>"+img+"<SPAN style='"+TICKER_STYLE+"' ID='TICKER_BODY' width='100%'> </SPAN>"+img+"</TD></TR></TABLE>"; tickerSupported = true; } // IE if (navigator.userAgent.indexOf("MSIE")!=-1 && navigator.userAgent.indexOf("Opera")==-1) { document.getElementById("TICKER").innerHTML = "<DIV nowrap='nowrap' style='width:100%;'>"+img+"<SPAN style='"+TICKER_STYLE+"' ID='TICKER_BODY' width='100%'></SPAN>"+img+"</DIV>"; tickerSupported = true; } if(!tickerSupported) document.getElementById("TICKER").outerHTML = ""; else { document.getElementById("TICKER").scrollLeft = TICKER_RIGHTTOLEFT ? document.getElementById("TICKER").scrollWidth - document.getElementById("TICKER").offsetWidth : 0; document.getElementById("TICKER_BODY").innerHTML = TICKER_CONTENT; document.getElementById("TICKER").style.display="block"; TICKER_tick(); } } function TICKER_tick() { if(!TICKER_PAUSED) document.getElementById("TICKER").scrollLeft += TICKER_SPEED * (TICKER_RIGHTTOLEFT ? -1 : 1); if(TICKER_RIGHTTOLEFT && document.getElementById("TICKER").scrollLeft <= 0) document.getElementById("TICKER").scrollLeft = document.getElementById("TICKER").scrollWidth - document.getElementById("TICKER").offsetWidth; if(!TICKER_RIGHTTOLEFT && document.getElementById("TICKER").scrollLeft >= document.getElementById("TICKER").scrollWidth - document.getElementById("TICKER").offsetWidth) document.getElementById("TICKER").scrollLeft = 0; window.setTimeout("TICKER_tick()", 30); } Code (markup):
Hi, I changed the code as; if(xmlHttp.readyState == 4){ var response = xmlHttp.responseText; TICKER.innerHTML = response; setTimeout('callServer()',5000); TICKER_CONTENT = document.getElementById("TICKER").innerHTML; TICKER_RIGHTTOLEFT = false; TICKER_SPEED = 2; TICKER_STYLE = "font-family:Arial; font-size:12px; color:#444444"; TICKER_PAUSED = false; ticker_start(); } Code (markup): Now, the content is ticking in Firefox. However, now the text accelerates continuously . What's the crazy problem?
it stacks up, thats why. every 5 seconds you add a new handler that gets news -- because upon each update you do not clear the previous setTimeout before adding make a new one. if you do the former, do in global scope: var timeoutFoo; oncomplete: clearTimeout(timeoutFoo); // clear al older assignments, just in case so they dont stack up. timeoutFoo = setTimeout(callServer, 5000); ... // reinit. or you can check the typeOf timeoutFoo and only do something if its not a number (which it will be if already assgined). incidentally, not a good script, should be much lighter and the only things being returned by the php script should be the headlines as a json object... anyway good luck
Thank you for your reply dimitar christoff.. Unfortunately I can't find the better script. I don't understand your solution because I have no ability with JavaScript . How can I locate in my codes these?
