JavaScript - Preload Frameset W/message Question
Hi, I am completely aware that Framesets are an outdated way of designing these days (I don't have time to redesign the site now), but I have a question:.
Is there a way I can have a "Please wait.. Loading.." message of some sort on the "contents.html" frameset? It takes a while to load.. Code: <html> <head> </head> <frameset rows="130,*" framespacing="0" border="0" frameborder="0"> <frame name="banner" scrolling="no" noresize target="contents" src="title.html"> <frameset cols="523,493"> <frame name="contents" target="main" src="contents.html" scrolling="auto"> <frame name="main" src="letters.html" scrolling="auto"> </frameset> <noframes> <body> <p>This page uses frames, but your browser doesn't support them.</p> </body> </noframes> </frameset> </html> Thanks so much. Similar TutorialsHi! I'm just starting to learn java script and have a questions. If anyone could answer this it'd be great. When preloading images for use in things like mouseout/on/etc what is the proper code? var image1, image 2; image1 = new Image() image1.src = "" image2 = new Image() image2.src = "" OR var image1 image1.... var image2 image2.... The book I have list both but only the 2nd way I listed works. Why? Thanks Is there a way to have the websites open in new windows? I've tried the standard ways, but script doesn't work when I change it. Does anyone know what and where in the script I can add for opening in new windows. Thank you The script is shown on this page: http://www.javascriptkit.com/script/cut181.shtml I'm looking to use some simple JavaScript code on a message board when I'm posting a reply to a thread. I believe there was some kind of namescript or namespace in JavaScript that would take the username of whoever opened the thread and place it in my post. So for example, if I said in a thread, "Welcome to my thread, [namescript]" it would place your board handle in the [namescript] function. Any of this sound familiar to anyone and they could possibly point me in the right direction for what I'm looking for? Hello, I've some javascript code which preload the images for a photo gallery made of clickable thumbnails and the images to be shown. The script is structured to preload the images in order to have a smooth experience while browsing through the thumbnails but, as the images are needed in quite high quality and can't be compressed any further, the page is too slow to load. Basically, as the script sits between the head tags at the beginning of the page, it holds the loading of the whole page, leaving the user with a black page for a good 10 seconds on a fast connection. Is there any chance I can preload the images in such a way I don't have to hold the whole page from displaying while the images are loaded? It would be ideal to be able to display the contents of the page (logo, menu, 1st picture of the gallery and foot of the page) while the images preload in the background. Could please anybody help with this? Here is the code I'm using: <SCRIPT language=JavaScript1.1> var myimages=new Array() function preloadimages(){ for (i=0;i<preloadimages.arguments.length;i++){ myimages[i]=new Image() myimages[i].src=preloadimages.arguments[i] } } preloadimages("images/gallery/editorial/1.jpg","images/gallery/editorial/2.jpg","images/gallery/editorial/3.jpg","images/gallery/editorial/4.jpg","images/gallery/editorial/5.jpg","images/gallery/editorial/6.jpg","images/gallery/editorial/7.jpg","images/gallery/editorial/8.jpg","images/gallery/editorial/9.jpg","images/gallery/editorial/10.jpg","images/gallery/editorial/11.jpg","images/gallery/editorial/12.jpg","images/gallery/editorial/13.jpg","images/gallery/editorial/14.jpg","images/gallery/editorial/15.jpg","images/gallery/editorial/16.jpg","images/gallery/editorial/17.jpg","images/gallery/editorial/18.jpg","images/gallery/editorial/19.jpg","images/gallery/editorial/20.jpg","images/gallery/editorial/21.jpg","images/gallery/editorial/22.jpg","images/gallery/editorial/23.jpg","images/gallery/editorial/24.jpg","images/gallery/editorial/25.jpg") function MM_swapImgRestore() { //v3.0 var i,x,a=document.MM_sr; for(i=0;a&&i<a.length&&(x=a[i])&&x.oSrc;i++) x.src=x.oSrc; } function MM_preloadImages() { //v3.0 var d=document; if(d.images){ if(!d.MM_p) d.MM_p=new Array(); var i,j=d.MM_p.length,a=MM_preloadImages.arguments; for(i=0; i<a.length; i++) if (a[i].indexOf("#")!=0){ d.MM_p[j]=new Image; d.MM_p[j++].src=a[i];}} } function MM_findObj(n, d) { //v4.01 var p,i,x; if(!d) d=document; if((p=n.indexOf("?"))>0&&parent.frames.length) { d=parent.frames[n.substring(p+1)].document; n=n.substring(0,p);} if(!(x=d[n])&&d.all) x=d.all[n]; for (i=0;!x&&i<d.forms.length;i++) x=d.forms[i][n]; for(i=0;!x&&d.layers&&i<d.layers.length;i++) x=MM_findObj(n,d.layers[i].document); if(!x && d.getElementById) x=d.getElementById(n); return x; } function MM_swapImage() { //v3.0 var i,j=0,x,a=MM_swapImage.arguments; document.MM_sr=new Array; for(i=0;i<(a.length-2);i+=3) if ((x=MM_findObj(a[i]))!=null){document.MM_sr[j++]=x; if(!x.oSrc) x.oSrc=x.src; x.src=a[i+2];} } </SCRIPT> and this is for the thumbnails: <a onmousedown='changeimage(myimages[0],this.href)'><img src="images/gallery/thumb1.gif" alt="1" width="16" height="16" border="0" /></a> <a onmousedown='changeimage(myimages[1],this.href)'><img src="images/gallery/thumb2.gif" alt="2" width="16" height="16" border="0" /></a> <a onmousedown='changeimage(myimages[2],this.href)'><img src="images/gallery/thumb3.gif" alt="3" width="16" height="16" border="0" /></a> <a onmousedown='changeimage(myimages[3],this.href)'><img src="images/gallery/thumb4.gif" alt="4" width="16" height="16" border="0" /><br /> </a> etc....

(10 in all) Code: <head> <script type="text/javascript"> PreImage1= new Image(width,height); PreImage1.src = "images/navbtn/onbtn_1.gif"; PreImage2 = new Image(width,height); PreImage2.src = "images/navbtn/onbtn_2.gif"; PreImage3= new Image(width,height); PreImage3.src = "images/navbtn/offbtn_1.gif"; PreImage4 = new Image(width,height); PreImage4.src = "images/navbtn/offbtn_2.gif"; </script> Will imgs be read from cache if I then do this?... or have I missed smthg? Code: <body> <img src="images/navbtn/offbtn_1.gif" onmouseover=this.src="images/navbtn/onbtn_1.gif" onmouseout=this.src="images/navbtn/offbtn_1.gif" alt="" /> </div> low tech I want to use an image as a CSS background-image so I used the Image constructor to load the image: Code: (new Image()).src="http://www.mediafire.com/imgbnc.php/432b35f2cc3340ea03d25128ada294476c92189353679dfb7e9cc9dfde6498f06g.jpg"; but I noticed that the browser (Firefox) load the image from the URL and not from the memory when changing the background-image property (it takes about 1.5 seconds before showing the image, and every time I reload the page!) Hi Everyone, I have created 8 thumbnails of their larger full sized pictures. Next I created a "picdiv" with CSS attributes within a center division. The thumbnails sit just above the "picdiv". I need code to open the full pictures in the "picdiv" when I click on the thumbnail. I've tried an on-click function but can't get this working either. Can anyone help please? Anita I have more than a hundred images (small ones though), which is a cut-to-pieces large image arranged in tables that I want to preload. I have been looking for a preload script that could possibly load all images in a folder by wildcard and if possible via JavaScript. Any suggestions? Any other language will be welcome as long as it will run on Linux. I have a good preload javascript here that I downloaded from hotscripts.com that displays a progress bar, percentage of download, and number of images downloaded. The bad thing is that creating an array out of a hundred images will be tedious especially with computer genereted filenames! If anyone knows of a program that could automate the process then we can forget the wildcard! Hehe! Hope someone has ideas . Thanks in advance. Hi! I have a website that requires preloading images a lot. I would like to preload only the most important images first and display the page as quickly as possible. After that it will take at least 20 seconds before the user will need the rest of the images. Is there a way of making two preloading groups and have the second group load in background after the page is already visible? My current preload code is simply like this: <SCRIPT language="JavaScript"> if (document.images) { pic01= new Image(200,200); pic01.src="images/base.jpg"; pic02= new Image(200,200); pic02.src="images/grump1.jpg"; pic03= new Image(200,200); pic03.src="images/grump2.jpg"; pic04= new Image(200,200); pic04.src="images/grump3.jpg"; pic05= new Image(200,200); pic05.src="images/grump4.jpg"; pic06= new Image(200,200); pic06.src="images/love.jpg"; pic07= new Image(200,200); pic07.src="images/smile1.jpg"; pic08= new Image(200,200); pic08.src="images/smile2.jpg"; pic09= new Image(200,200); pic09.src="images/smile3.jpg"; pic10= new Image(200,200); pic10.src="images/smile4.jpg"; pic10= new Image(200,200); pic10.src="images/rotate.gif"; } </SCRIPT> Hello, I'm not sure if this is the best forum for my question or not, but I'll explain what I'm doing and we'll see. I am trying to make a little easter egg hidden inside a web application and its going great except I'd like to hide my .gif files by changing their file extension to something like .dat instead so it won't be so obvious what they are. Basically all I really want to do is have an html image tag that points to a file who's extension is not gif, but really does contain gif content. (I want to mask the fact that the file is really a gif when looking at it in the directory listing.) So, my idea was I would point the <img src=""> tag's src attribute to a cgi script that could write out a Content-type: image/gif header and return the binary gif data. So, I did this and it worked great, but its really slow. (I output the image multiple times and animate it.) So, I thought I could maybe use Javascript to preload these cgi requests and cache them, but every attempt I've made to do this fails! It's like the browser doesn't want to cache the cgi requests. My method of attempting this was to create Image() objects in javascript and set their src attribute to my cgi script call and then set an onload to keep track of when they were all loaded. That seemed to work fine, but then when I try to display an image with the src tag equal to the cgi location (after they were all loaded) its like it goes and reads the code to pull it down again instead of using a cached copy because its really slow. So, then I thought, hey maybe I could just manually edit the binary content of the gif file (which has an extension like .dat) to also contain Content-type: image/gif\n\n embedded at the front of the file. So, I opened the binary file with a hex editor and inserted that text content at the front... but it didn't work. I had <img src="myfile.dat"/> Is there an easy way to make the browser recognize my gif file even if I don't use a gif extension? If not is there a way to preload and cache cgi responses with Javascript so that they don't keep reloading each time I refer to them? Any other ideas? Thanks.
Hello All! Brand new to Javascript here, so please forgive my basic question. I did a search but did not find exactly what I was looking for. My web site has a splash page with a large image broken into pieces and displayed in a table. I want to preload the images so the user doesn't see the table slowly "fill in" when using a slower internet connection. I have written a basic script, using the basic format of: <SCRIPT LANGUAGE="JavaScript"> Image1= new Image(50,60) Image1.src = "something.gif" Image2 = new Image(70,80) Image2.src = "somethingelse" Image3 = new Image(90,100) Image3.src = "lastsomething.gif" </SCRIPT> and saved it as a .js file and placed it in my sites root directory. Just to be safe, I've placed the images there too. (do I have to do that though?) Still, it does not seem to be working. Below is the head from my splash page. Have I missed somthing here? I thought that by putting the script reference in the head, the images would be loaded before the table came up, but such does not seem to be the case. Any help would be most appreciated. Thanks! <html> <head> <title>Finish Well Endurance</title> <meta name="generator" content="Namo WebEditor"> <link type="text/css" rel="stylesheet" href="http://www.fwe1.net/css/index.css"> <script type="text/javascript"language="javascript"src="loadimages.js"></script> </head> <body bgcolor="#464646" text="black" link="#464646" vlink="#464646" alink="#464646"> <table border="0" align="center" cellpadding="0" cellspacing="0" width="600"> Hey, I'm a javascript newbie and am frankensteining various bits of code I have managed to find on Lightboxes, preloading, and swapping image Basically, what I want to happen is to run the mouse over the thumbnails on the left side of the page and a larger version of that is in the middle, while information on the right changes to match the picture in the middle.

I think it's because the images in the center don't have a source, only a name, but I'm not sure where I would fit that in. I tried putting it in the second set of code, but it did not work out. Hello, First time on the forum and I am admittedly a complete noob, so forgive me for any grievous misconceptions. I am a teacher trying to create a bulletin board on my website where students, teachers, and parents can post messages. I am trying to use the site linoit.com I am trying to embed that site on my website using an iframe url: http://www.capretto.net/stickyboard.shtml My problem is that when you go to the message board on my site it asks your for a username and password to login to access my message board from linoit. I was hoping there is a scripts or other trick that will auto fill the username and password when the page loads so that the message board opens automatically. Not too worried about privacy, but I could distribute the username and password to all interested parents, teachers, etc. but in my experience one more step between students and the information they need can be the difference between them not receiving the info. I'd be happy to give any contributors credit on my site for their coding help. Thanks in advance. Can someone help me with this? I have a frameset built as follows: <FRAMESET cols="20%, 80%"> <FRAME src="red.html"> <FRAMESET rows="100, 200"> <FRAME name="green" src="Green.html"> <FRAME name="blue" src="Blue.html"> </FRAMESET> Then I have a function built in the red.html page to set the frame[green] to the blue.html source location. attached to a button on the red.html form. <script language="javascript" type="text/javascript" > window.onload = function colorchange() { top.location.green="blue.html"; } </script> top.location.green="blue.html"; just does not seem to do anything.. Can someone help with this. I have a menubar across the top of a page in a separate frame. Content loads into main frame below it. I'm adding an onClick menu option that I'd like to open in the same, full window, without the menubar frame on top. Any way to do this? Thx. Hi: I got a blank page returned when using javascript within the Frameset. Here is part of my codes: (my javascript part) <script language="JavaScript"> //this function will be used to get the parameter from URL using javascript function gup (name) { name = name.replace(/[\[]/,"\\\[").replace(/[\]]/,"\\\]"); var regexS = "[\\?&]"+name+"=([^&#]*)"; var regex = new RegExp( regexS ); var results = regex.exec( window.location.href ); if( results == null ) return ""; else return results[1]; } //get the transactionID from the URL var transactionID = gup('name'); //add the transactionID as the URL parameter var url = "../../onetwothree/Approve.jsp?name=" + transactionID + '\"'; var temp = '<frame name=\"onetwothree\" ' + 'src=\"' + url + '>' + '</frameset>'; </script> ---------------------------- (my html part) <frameset rows="0,*" border="0" frameborder="0" framespacing="0"> <frame name="onetwothreeFrame" src="../onetwothree/abcd.html" marginwidth="0" marginheight="0" scrolling="no" noresize> <script language="JavaScript"> document.write(temp); </script> </frameset> Hi friends, <script language="JavaScript" > calDocFrameset = "<frameset rows='60,*' frameborder='0' sty >\n" + " <frame name='topCalFrame' src='javascriptarent.opener.calDocTop' scrolling='no'>\n" + " <frame name='bottomCalFrame' src='javascriptarent.opener.calDocBottom' scrolling='no'>\n" + "</frameset>\n"; document.write(calDocFrameset); </script> the above code i am using for popup calendar. It is working fine with IE.But it is not working in mozilla and GoogleChrome. In mozilla and gc it is comming in center. It is appearing only when i maximize the window. Even though i have given window properties as window.open('/includes/calendar.htm','cal','dependent=yes,width=180,height=180,left=400,top=250,titlebar=yes,resize=no'); I want the calendar to appear in popupwindow without maximizing. Srikanth With the help of Aerospace_Eng in a 2005 codingforums thread, now I can use one link (for example in a page about Topic 3) to load two related pages about Topic 4 (left-4.htm and right-4.htm) into the “left” and “right” iframes, using the code below. ___Is it possible to use this code, suitably supplemented, to also specify the frameset at “home.htm” if an external link to “right-4.htm” loads it into a browser without the frameset? (i.e. by putting a link into right-4.htm that will load it and left-4.htm into the iframe-context of home.htm) Code: <head>
<script> function changeLink(link) { parent.right.location=link; } </script>
</head>
<body>
<a href="left-4.htm" target="left" onclick="changeLink('right-4.htm'); return true">for Topic 4</a>
</body>
I have a main window which produces a number of child windows when I press a button. Users need to be able to switch between windows using Ctrl+Tab hot key. I was trying to implement this by intercepting keyup/keydown events in one of the frames. But the problem is that main window has several frames and I don't have access to all of them because some of them are in different domains. As soon as a user clicks on a frame without my handler the hot key is not working anymore. Any ideas how to implement it? Maybe an ActiveX component? If ActiveX could help me - how does it work? Are there any tutorials or examples how to write an activeX to intercepts hot keys in IE? Thank you. |
