JavaScript - What's This? If(t) Refresh = Settimeout(\"document.location='index.php';\", T*1000);
Can someone explain what this does?
Code: ... <script language=\"Javascript\" type=\"text/javascript\"> function SecCheck(t) { if(t) refresh = setTimeout(\"document.location='index.php';\", t*1000); } </script> </head> <body onLoad=\"SecCheck(30)\"> ... Similar Tutorials. SOURCE: Here Code: 1 document.onmousemove = mouseMove; 2 3 function mouseMove(ev){ 4 ev = ev || window.event; 5 var mousePos = mouseCoords(ev); 6 } 7 8 function mouseCoords(ev){ 9 if(ev.pageX || ev.pageY){ 10 return {x:ev.pageX, y:ev.pageY}; 11 } 12 return { 13 x:ev.clientX + document.body.scrollLeft - document.body.clientLeft, 14 y:ev.clientY + document.body.scrollTop - document.body.clientTop 15 }; 16 } #1: How is it that "mouseMove" is assigned to "document.onmousemove" from right-to-left? What exactly is taking place here? #3: How can "mouseMove" be declared as a function afterwards? #3: I periodically see "e" being placed in functions. Is "ev" taking the place for "e"? If so is "ev" or "e" a global object? Where do they initially come from and how do they work? .

Thank you Is there a difference between right clicking an iframe and reloading post reponse vs. using javascript to reload the frame? So far, the javascript route hasn't worked for me. [some context] I am writing a little bookmarklet to help me with the online registrations at my school. Here is the setup. Load up a page on the domain. Remove all body elements. Insert an iframe. Set iframe to page for class roster search. (in iframe on school search page) Select class search options, POST the form data, and view results in frame. *This works perfectly, but I need to have it refresh results every minute or so. When I use frame.contentDocument.location.reload(true); the frame loses the post data or something and the page is broken. BUT when I just right click on the frame and select "reload frame" it works perfectly. Whats the deal here? What is the difference between rightclicking the frame and refreshing it like that vs. using javascript to reload the frame? PS: using chrome Okay, I'm trying to refresh my iframe ads, 3 of them. The code works, its just making the functions work "per" ad. When it refreshes, it changes "all" ads, I want them to refresh at different RATE Code: function reloadFrames(first, refresh){delay = 0.2; //minutes to delay the refresh max_refreshes = 3; if (max_refreshes > refresh){refreshed = refresh + 1;setTimeout("reloadFrames(false, refreshed)", delay*60*1000); if (!first) {ads = document.getElementsByName("ad");for(var i=0; i<ads.length; i++) {ads[i].src = ads[i].src;}}} } function reloadFrames2(first, refresh){delay = 1; //minutes to delay the refresh max_refreshes = 3; if (max_refreshes > refresh){refreshed = refresh + 1;setTimeout("reloadFrames(false, refreshed)", delay*60*1000); if (!first) {ads = document.getElementsByName("ad2");for(var i=0; i<ads.length; i++) {ads[i].src = ads[i].src;}}} } function reloadFrames3(first, refresh){delay = 1.4; //minutes to delay the refresh max_refreshes = 3; if (max_refreshes > refresh){refreshed = refresh + 1;setTimeout("reloadFrames(false, refreshed)", delay*60*1000); if (!first) {ads = document.getElementsByName("ad3");for(var i=0; i<ads.length; i++) {ads[i].src = ads[i].src;}}} } ad codes: Code: <iframe frameborder="0" marginwidth="0" marginheight="0" scrolling="no" width="728" height="90" src="http://ad.103092804.com/st?ad_type=iframe&ad_size=728x90§ion=656647" name="ad"></iframe> <iframe frameborder="0" marginwidth="0" marginheight="0" scrolling="no" width="120" height="600" src="http://ad.103092804.com/st?ad_type=iframe&ad_size=120x600§ion=656647" name="ad2"></iframe> <iframe frameborder="0" marginwidth="0" marginheight="0" scrolling="no" width="160" height="600" src="http://ad.103092804.com/st?ad_type=iframe&ad_size=160x600§ion=656647" name="ad3"></iframe> Is this possible to get each iframe to refresh at a different rate, or even combine the functions into one? I dont code much javascripts. Thanks -Tim Hey, I have two iframes like this: iframe1 = chat window iframe2 = form to enter text to chat Now currently i have iframe1 with a meta refresh on every 1 second. But i've seen live chats before with JS which are not refreshing the page all the time or so it appears...what i mean by this as the meta refreshes the first iframe my browser shows a status bar and loading symbol on firefox, but an old js chat i saw which wasn't free script didn't do this it was pure smooth and didn't look like it was refreshing all the time even if it was it hid it well. How was that done because my method sucks incomparison with make a live chat look "live". Hope you can help me. Hello, I am needing help with "location.pathname.

I seriously could use as much help as possible! Hello, recently I have been to many government websites where I have noticed that the programmer has used window.open() method in JavaScript to link to different pages instead of using <a> tags! I was just getting curious to know whether it is normal or has it been used due to security concerns(if any, I don't know)? Any comments? Hi all, I'm having a bit of a problem..

ANY help is GREATLY appreciated! Hello, I run a online gaming website, and I'm having problems with certain websites iframing our games. Actually I'm ok with iframing, as long as they include the banner ad located just beneath our games. But often times unscrupulous webmasters will iframe only the game, preventing us from generating any revenue from the banner ad (and costing us additional bandwidth charges). I'm hoping to find a way to detect the dimensions of the iframe, so that I may dynamically resize the game, in order to include the banner ad within the iframe. Does anybody know how to extract the "height" and "width" attribute values from an <iframe> tag sitting on a different site? Regards, Steve |
