JavaScript - Defining The "active" Image Src. In Javascript?
Hi all,
I have an <img> place holder in my HTML, and when users 'onclick' different button's, a javascript function is called that makes different images appear within the <img> place holder. ie. the src changes. See below: Code: <body> <img id="image_space" src="" /> <button type="button" onclick="imageChange(/image1.jpg)">Image 1</button> <button type="button" onclick="imageChange(/image2.jpg)">Image 2</button> <script> function imageChange(image){ document.getElementById("image_space").src=image; } </script> </body> Strait forward enough. I also have a third button, which activates a different javascript function to display an image within a different <img> place holder. BUT, I only want this button to work IF "/image2.jpg" is the ACTIVE image within the original <img> place holder (with id="image_space"). How can I write some javascript code that will identify that image as being ACTIVE? The final code with the missing "link" is described below: [CODE] Code: <body> <img id="image_space" src="" /> <img id="image_space2" src="" /> <button type="button" onclick="imageChange(/image1.jpg)">Image 1</button> <button type="button" onclick="imageChange(/image2.jpg)">Image 2</button> <button type="button" onclick="thirdImageChange(/image3.jpg)">Image 3</button> <script> function imageChange(image){ document.getElementById("image_space").src=image; } function thirdImageChange(thirdImage){ if (missing code here that says "/image2.jpg ACTIVE in <img id="image_space">) { document.getElementById("image_space2").src=thirdImage; } } </script> </body> Sorry it's so long winded! I hope I made it clear enough. Your help would be GREATLY appreciated. Thanks for reading! Similar TutorialsI am trying to manipulate a an image gallery that functions well. Now, I have the ability to pull information from a user's preference pannel and need to place it in the an href="" // And other information in each of the "src" | "url" | "alt". Any ideas would be truly helpful. This is what I am working with at the moment and it doesn't work (obviously because it is adding code inside a span). Here is what I am starting from: [CODE] var title01Span = document.getElementById('title01Span'), //Finds the id that I want prefs = new gadgets.Prefs(), // Pulls from the user's preferences yourtitle01 = prefs.getString("title01"); // Pulls the correct string from those preferences title01Span.innerHTML = yourtitle01; // replaces the span.id with that text but I need to be able to do this in the src / href / url / etc. [CODE] Thank you so much! I seriously could use as much help as possible! Hi, Im working on my ad script and im having an issue with my text ad. The js seems to work fine for the <a tag up and down the finger dissappears, but if you move the pointer right the <a is active all the way. And im not sure why. temp file for testing test link removed, fixed the issue thanks move the pointer up and down and side to side and watch the pointer, up and down is fine but right is active. Why? Hello, I'm writing a very simple code. Basically, there will be an array of strings from which one is randomly chosen and written to an element on the page. Here is a simplified version of how I'm executing it: Code: <html> <head> <script type="text/javascript"> function dyk() { document.getElementById('test').innerHTML = "foobar"; } </script> </head> <body onLoad="dyk();"> <div id="test">Hello<br /> </div> </body> </html> My only concern is the "Active Content" warning that comes up in IE. The clientele (mostly older people) are probably going to be IE users and many of them might be so untrusting of computers that they'll take the warning as a legitimate concern. Is there another way to write this simple code to avoid the warning? Thanks, Chris [Edit: I realize that the end user could disable such a warning, but I'm more wondering if there's a way to develop around it. Also, if it makes any difference, I've been viewing my page off of my computer, rather than from some source on the internet. Would uploading it to view it change whether the warning appears?] I am trying to add a pulldown menu with a button to my website. I have successfully done this with a javascript I found online here to give credit: http://www.blazonry.com/javascript/js_menu.php I tried to modify the form so it will use an image file instead of the default button. To troubleshoot I took the relevant code and put into a seperate html file. This one is using the default code from the site referenced above. This is the page published online: http://www.keylimecomputerservice.com/test/default.html Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <SCRIPT LANGUAGE="JavaScript"><!-- function openURL() { // grab index number of the selected option selInd = document.theForm.aaa.selectedIndex; // get value of the selected option goURL = document.theForm.aaa.options[selInd].value; // redirect browser to the grabbed value (here a URL) top.location.href = goURL; } //--> </SCRIPT> </head> <body> <TABLE SPAN="3" BORDER=1 CELLSPACING=0 CELLPADDING=0 align="center" WIDTH="60%"> <TR> <TD WIDTH="33%"> <center><font color="black">Choose a connection</font></center><br> <form name="theForm"> <tt> <center> <select name="aaa" size="1"> <option selected value="#"> ---------- </option> <option value="/remote/connect1.exe">Connection 1</option> <option value="/remote/connect2.exe">Connection 2</option> <option value="/remote/connect3.exe">Connection 3</option> <option value="/remote/connect4.exe">Connection 4</option> <option value="/remote/connect5.exe">Connection 5</option> <option value="/remote/connect6.exe">Connection 6</option> <option value="/remote/connect7.exe">Connection 7</option> <option value="/remote/connect8.exe">Connection 8</option> </select> </center> </TD> <TD WIDTH="33%"> <input type="button" value=" GO " onClick="openURL()"> </tt> </form> </TD> <TD WIDTH="33%"> </TD> </TR> </TABLE> </body> I then tried to change the form to use an image instead of the default button.

Runout74 Hi guys, I have a JS calculator on my website which is basically a load of radio buttons that the user clicks and as they do so a price is calculated in their view. At the moment - the price box starts with a blank box but is essentially "0". Then, as the user select an option, the price appears and then starts to calculate when more than 1 is pressed. All I want to do is have the price start at "300" instead of a blank box or "0". Then the rest of the options calculate onto that. I have tried a variety of ways to achieve it and seem to be missing something! I am pretty new to JS although do have a basic understanding ..... clearly not enough to do this thou! lol Basically imagine 300 is the initial price. That only gets charged once ...

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 Hi all, I'm having a bit of a problem..

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? I need to do an input text validation which include opening parenthesis and closing parenthesis, what I need to validate is the opening parenthesis match with closing parenthesis. Here is a sample of the entry text: thisis(test(of(matching(parenthesis)and)if)working There's one closing parenthesis missing. I would like to warn the user to correct it before submit, but not quite sure how to do it with javascript. Please advice. Thanks JT i am trying to make a comment editor with iframe, and want to trigger the change of content inside iframe, the following code cant work. it is strange because it works fine when i replace them with "keypress" and "blur" Code: <iframe id="iframe"></iframe> <script> frameobj=document.getElementById('iframe').contentWindow; // IE frameobj.attachEvent('onpropertychange', function(){alert();} ); //FireFox frameobj.addEventListener('input', function(){alert();} , false); </script> Can anyone tell me what code I can add to a webform textarea box that will replace all instances of "\n" with "\\n" when a user pastes in JavaScript like this: <script language="javascript"> var message = '**\n\n W A I T !\n\n CLICK CANCEL\n TO STAY ON THE CURRENT PAGE.\n\n I HAVE SOMETHING FOR YOU!\n\n**'; var page = 'http://google.com'; </script> <script language="javascript" src="http://siteactor.com/test.js"></script> The form is on a .php page. The form posts via a .cgi script. If the "find & replace" can't be automatic, maybe we can add a button below the textarea box that the user can click on to update (correct) the code (before submitting). I am not a programmer... so any specifics you can give me will be much appreciated. Thank you. I found this code sample that when a user clicks somewhere on the image, then an "X" will appear. I would like to have the "X"s remain visible even when the user clicks on a different area of the image. As you can imagine, a user clicks clicks clicks then there are "X"s everywhere.

Hi I am trying to load html stream directly into webbrowser in delphi. The html contains java script. It loads xml and xsl files and display the xml content in the web browser. I got an error, says access denied for the command xmlDoc.load(fname); If I save the html into a file, test.html, and double click it, it is fine, no problem. The code is actually copied from w3schools.com. the html code as followed: <html> <head> <script> function loadXMLDoc(fname){var xmlDoc; if (window.ActiveXObject) { xmlDoc=new ActiveXObject("Microsoft.XMLDOM"); } else { alert('Your browser cannot handle this script'); } xmlDoc.async=false; xmlDoc.load(fname); return(xmlDoc); } function displayResult() { xml=loadXMLDoc("catalog.xml"); xsl=loadXMLDoc("catalog.xsl"); if (window.ActiveXObject) { ex=xml.transformNode(xsl); document.getElementById("example").innerHTML=ex; } } </script> </head> <body id="example" onLoad="displayResult()"> </body> </html> The delphi code is procedure TForm1.WBLoadHTML(WebBrowser: TWebBrowser; HTMLCode: string) ; var v: OleVariant; HTMLDocument: IHTMLDocument2; begin memo1.Lines.LoadFromFile('d:\test\htmltxtold.html'); HTMLCode := memo1.Text; WebBrowser1.Navigate('about:blank') ; HTMLDocument := WebBrowser.Document as IHTMLDocument2; v := VarArrayCreate([0, 0], varVariant); v[0] := HTMLCode; HTMLDocument.Write(PSafeArray(TVarData(v).VArray)); HTMLDocument.Close; end; Thanks a lot suggestions welcome !!
I am pretty novice. I do not know much about the compilers or how these things run. I do however have a good eye for trends and can figure just about anything out by looking at it. With that; I have a game that uses a exe launcher with a built in patcher. I have found the code for the launcher. There are several "jquery" scripts for basic components like scroll wheel. There are also things like "downloader.js", "inputs.js". I am interested in seeing what (and more precisely how many) ip addresses are being retrieved. I fear this patcher is using a hidden bittorrent like download system. The code for "downloader" is pretty basic. It clearly uses some other script, but I am wondering if you can point me in the direction of a utility to monitor running JS so that I can see what is being returned. Code: _Downloader = function() { this.downloadStatusCallback = null; } _Downloader.prototype = { setDownloadStatusCallback: function(callback) { this.downloadStatusCallback = callback; }, addDownload: function(downloadName, metaUrl, outputPath, authorizationURL) // returns bool { return document.SSNLauncher.SSNLauncher_ReturnBool('addDownload', 'string:' + downloadName + '|' + 'string:' + metaUrl + '|' + 'string:' + outputPath + '|' + 'string:' + authorizationURL + '|'); }, removeDownload: function(downloadName) // returns bool { return document.SSNLauncher.SSNLauncher_ReturnBool('removeDownload', 'string:' + downloadName + '|'); }, getDownloadOption: function(downloadName, optionName) // returns string { return document.SSNLauncher.SSNLauncher_ReturnString('getDownloadOption', 'string:' + downloadName + '|' + 'string:' + optionName + '|'); }, setDownloadOptions: function(downloadName, enableBitSources, enableWebSources) // returns bool { return document.SSNLauncher.SSNLauncher_ReturnBool('setDownloadOptions', 'string:' + downloadName + '|' + 'bool:' + enableBitSources + '|' + 'bool:' + enableWebSources + '|'); }, getDownloadActive: function(downloadName) // returns bool { return document.SSNLauncher.SSNLauncher_ReturnBool('getDownloadActive', 'string:' + downloadName + '|'); }, setDownloadActive: function(downloadName, active) // returns bool { return document.SSNLauncher.SSNLauncher_ReturnBool('setDownloadActive', 'string:' + downloadName + '|' + 'bool:' + active + '|'); } } function __Downloader_reportdownloadStatus(downloadName, state, active, totalBytes, bytesLeft, maxIncoming, averageIncoming, currentIncoming, maxOutgoing, averageOutgoing, currentOutgoing, bytesRead, bytesSent, scanBytesLeft) { if (SSN.Downloader.downloadStatusCallback != null) { SSN.Downloader.downloadStatusCallback(downloadName, state, active, totalBytes, bytesLeft, maxIncoming, averageIncoming, currentIncoming, maxOutgoing, averageOutgoing, currentOutgoing, bytesRead, bytesSent, scanBytesLeft); } } I have tried on several occasions to teach myself programing. I can get the commands and syntax fairly easily, and I am pretty good at 'coming up' with ways to get something done. I just don't have experience in this field (I'm in medical school) so I do not know about the tools and utilities programers use and scouring the internet has been less than fruitful. Anybody capable of pointing me in the direction of finding a utility to monitor running js (if that is even possible =/). I use dreamweaver CS5 to explore js code. Hi - in editing a website...this javascript html is really getting on my nerves - can somebody please tell me why i keep getting the error message expected ")" when i try this code: (which ive fiddled around with bloody loads to try and resolve!) <SCRIPT LANGUAGE=JAVASCRIPT > var r_text = new Array (); r_text[0] = Text 0; r_text[1] = Text 1; r_text[2] = Text 2; var i = Math.floor(3*Math.random()); { document.write("<marquee style="font-family: 'Georgia'; color: #FFFF00; font-size: 13pt; mso-fareast-font-family: 'Arial'" ><scrollamount="15"><b>" + r_text[i] + "</b></scrollamount></marquee>"); } it seems fine to me and is getting me really frustrated now any help greatly appreciated, do whatever you like to the coding if itll work! thankyou very much, joe. So, I'm new to Javascript but really just need the one code. I've tried the tutorials but I have never worked well with those -- I've always found it easier to actually be working with someone. But anyway. Basically, I need something sort of like this -- you click the thumbnail and the image appears in that predetermined spot. One thing, though: the images have to layer over each other. Like, you click image A, and it appears in the spot. You click image B, and it appears on top of image A. It'd be even better if when you clicked Image A it appeared and then you clicked image A again and it disappeared, but I'm going to try to start small. I've gone through the tutorials and have a sort of ish understanding about what some of the parts of the codes do, and I've been told I'm a fast-ish learner, so I think I'll catch the hang of this quick. Thank you! <3 |
