JavaScript - Image File Name
I am trying to grab the file name of an image generated by a PHP file. I first tried loading the image in an iframe, letting it load, and then grabbing the src; but IE and Fx security measures denied me access to both the src and the href of the iframe. Then, I tried storing the iframe in an object variable after loading and reading the src / href of the variable, but it was always null. Finally, I decided to replace the iframe with an image tag...and it actually started to work. I could access the src after the image had loaded! The only problem is...it is giving me the original src, when what I want is the src generated by the php file that I am using as the image src. As a last personal attempt, I stored the image tag into an Image object, and then used the name method to try and get the file name of the image inside of the tag, but again...that is just returning the src of the php file.
Here is where the code is loading: http://avatars.imvu.com/GetInfo Can anyone tell me how to get the file name of an image? Code: <script type="text/javascript">
var UserID='';
var aviName='';
var aviPicBegin = 'http://www.imvu.com/catalog/web_av_pic.php?av=';
var aviPicFull='';
var aviPic2='';
var myIMG = imgDisplay;
function input() {
aviName = fInput.txtAviName.value;
aviPicFull = aviPicBegin + aviName;
document.getElementById('imgDisplay').src=aviPicFull;
}
function display() {
myIMG = imgDisplay;
//aviPic2 = imgDisplay.src;
//myIMG.src = aviPic2;
alert("img src = " + myIMG.src);
//userID=;
// document.fOutput.txtID.value = userID;

Thanks to everyone who took the time to read this. Similar TutorialsSo I have a gallery which is displaying images from an array called imgList. When they are displayed I want the user to be able to link directly to the image. Is there a simple way to do this? The JavaScript: Code: //<!--

The HTML where it is displayed: Code: <img id="mainImg" src="images/gallery/1.jpg" style=" border: solid #7d3d3d 5px;" alt="galleryimage" /> I have a form that allows photos to be uploaded. I am using Perl to do this, and it works fine. Now I want to validate that the size of the image does not exceed a certain limit BEFORE it actually uploads. I can do that in Perl using something like the code below. But, I would rather do this in Javascript. I already have a routine that validates that the image file name does not contain embedded spaces. I would like to add this there. Can this be done in Javascript? Code: if ($ENV{'CONTENT_LENGTH'} > 100000) { print "SIZE EXCEEDS LIMIT!" }
Hey, I need some JavaScript code which will display the width and height of an image, before it is created on the page, so from the file itself.
Hi, I am new to this forum but I am in dire need of help. I am sorry if this isn't they way you normally do things. I read through some of the rules, but it is late and I am in a hurry. Any help would be greatly appreciated. I need the image file names in my array to be shown in the text box. I am not quite sure how to do this. I have been trying for some time but cannot figure it out.

I would like to avoid making 300 list items (as is necessary with all of the auto rotators and other jquery plug ins that I've found) but to have the images load straight from the folder after the rest of the website has loaded. It wold be nice if maybe there was a pretty horizontal scroll bar or something and the image in the middle of the page was biggest if possible, but I'm really not picky. I don't know what the best way is to display so many photos! They don't need captions or anything. Any ideas??? Thanks! Hey everyone, I'm working on a website, and I have one page that uses a forum that is supplied by tal.ki. The forum works fine, but the .js file that the forum uses is grabbing the image that I am using as my header on the page (not in the header of the html, just on top of the page) and moves it down and right from where it is supposed to be. My apologizes for the file being so long, but I have no idea which line it is that makes the image move. If needed, I have pictures of how it looks in the program that I use, vs. how it looks when viewed in a browser. Thanks so much (in advance) for any help. Code: if (!window.chatter) {

I'm try to set up a webpge that will play a live flash video on the left-hand side(got that part working) and display one slide of a presentation(jpg) to the right of the video. I would like to be able to control when the slide image changes by having some js check a text file on my server. The text file could contain something as simple as "Slide1.jpg". I will manipulate the text file with some code I've already written. Is there some simple js code I can put in my page that will cause it to check the text file every 5 seconds, and if the content of the file has changed, to refresh the image on the page with the new image? I'm try to get away from the "clicking" sound that is caused by doing a simple refresh of an Iframe. I'm a complete novice at js, so any help would be appreciated. I'm also open to other solutions that would accomplish the same thing. Thanks, Mike I've created a javascript version of the classic game SOKOBAN. Basically what happens is you move the man around the "warehouse" and he must push the boxes into the target area. Copy the code and try it yourself to see what I have so far (note-he can't move the boxes yet). My question is: Right now, my map consists of solid color blocks. What I WANT them to be is image files (for example: box.png, wall.png, floor.png) to add a little versatility and life to the map. I am not sure how to make this switch though. I suspect I make the change somewhere in the tile array in the initialize function, but I am not sure what.. Also, how can I get the boxes to actually MOVE? I.e. when my man pushes them, they move around in the direction he pushes? Any help would be much appreciated.

It always comes up as a single full line of the code instead of the sections I want. The code includes the student number first name last name and three results of assignments. I want the code to write the student number and three results of all the students into a file and then work out the average of the student results. Can you help? Code: try{

All -- I have a JavaScript config file called gameSetting.js which contains a bunch of variables which configures a particular game. I also have a shared JavaScript library which uses the variables in gameSetting.js, which I include like so: <script type="text/javascript" src="gameSetting.js" ></script> <script type="text/javascript" src="gameLibrary.js" ></script> In gameSetting.js I have: $(document).ready(function() { // call some functions / classes in gameLibrary.js } in Firefox, Safari, and Chrome, this works fine. However, in IE, when it's parsing gameSetting.js, it complains that the functions that live in gameLibrary.js aren't defined. When it gets to parsing gameLibrary.js, the variables in gameSetting.js are reported as not being defined. I've tried dynamically bootstrapping the gameLibrary file using this function in document.ready for dynamic load... $.getScript("gameLibrary.js"); However, the same problem still happens in IE, where when it parses the files individually it's not taking into context the file/variables that came before, so it's not an out of load order problem. My options a 1) collapsing all the functions in gameLibrary.js and variables in gameSetting.js into one file. However, this is not practical because this is dealing with literally hundreds of games, and having a gameLibrary.js in ONE location for ONE update is what makes most logical sense. 2) figure out a way to get this to work where variables in file1 are accessible to file2 in IE (as it seems they are in other browsers). jQuery seems to be able to have multiple plugins that all refer to the based jQuery-1.3.2.js, so I know there is a way to get this to work. Help appreciated. Nero help me! im have 2 file .js file 1.js code: document.write("<script src=2.js></script>") document.write(f) file 2.js code: var f="hello" im want run 1.js get variable of file 2.js by 3.html but don't run! code 3.html <script src=1.js></script> I tried to follow directions here http://www.javascriptkit.com/javatut...ernalphp.shtml and here http://codingforums.com/showpost.php...91&postcount=4 without any luck.

The .js file has this line inserted where I want the javascript from the .php file to go: Code: <script type="application/x-javascript" src="http://blackburnseminars.com/wp-content/themes/blackburn/get_regis_prices.php"></script> ...but the code from the .php file doesn't show when I load the .js file. Can anyone tell me what I am doing wrong? Also, do I need to enclose the lines inside document.write()? - (I'm not clear on that) Thanks much Tom Esker I have gotten my script to do exactly what I want it to do with one exception. I have some thumbnail images that people can mouse over and the actual image is 100px by 75px. That is what I use for my thumbnail and they reside in www.website.com/images/thumbs/image1.jpg. I have the large version of the image that resides in www.website.com/images/image1.jpg. Its actual size is 640px by 480. When I mouse over my thumbnail, I don't want the thumbnail to appear for the larger image, I want the large image to appear instead? Let me know if you need ellaboration. Any help would be great! Thank you. Javascript Code: <script language="JavaScript">
function Change_Big_One(thumb){
document.getElementById('BigOne').src=thumb.src.replace("_th","")
}
</script>
HTML THUMBNAIL Code: <div><img src="https://www.website.com/images/thumbs/image1.jpg" class="thumb" onMouseOver="Change_Big_One(this)"></div> HTML LARGER IMAGE Code: <div><img src="" id="BigOne"></div> Hello, I am working on a page that has a jQuery full browser BG image and I am trying to also utilize a MooTools gallery. There seems to be some interference between the two JavaScripts as only one works (whichever one is last in order in the header of the HTML document). Links: http://www.courtneyhunt.com.au/press_bg.html http://www.courtneyhunt.com.au/press_gallery.html I am a complete novice with JavaScript so if anyone could help that would be great. Thank you in advance. QUESTION 1: Hello. I would like to know if this is possible with Javascript, and if yes, if someone can please provide me with the code or point me in the right direction. Let me start of by saying that this is for an eBay listing. I know that they accept basic / limited javascript and if what I am asking is possible, I hope that it can work on eBay listings. I would like to know if it's possible to determine the dimensions of an image with Javascript from an Image url, and to then resize it or not based on the the size of the image. So, let's say this is the URL: www.adomainname.com/image.jpg and let's say that image is 1400 px x 1400 px. I would first like the javascript code to detect that size. I also would like the maximum dimension for any side of the image to be 600 px. If both sides of the image are over 600 px, for both sides to be reduced proportionally to 600 px or lower. If any one side of the image is larger than 600 px, the image is to be resized to 600 px or lower. If both sides are under 600 px, the image is to not be reduced. It would also be nice if it can detect whether the image is portion or landscape based on I guess the larger side, because an image at 600 px in height might be too big, but in width might be o.k. So, in this example (the 1400 px by 1400 px), the image is to be resized to 600 px x 600 px. For an image that's 300 px x 500 px, it should remain as such. For an image that's 400 px x 700 px, it should be resized to 400 / (700 / 600) px by 600 px, which is approximately 343 px x 600 px. I have looked a bit into this and I see things being mentioned about the image being loaded first completely on the screen, or about using server side language like PHP, and so on, but like I said, keep in mind that this is for eBay, and so I am limited. Note: The part that I am most interested in is in being able to detect the size / dimensions of the image. QUESTION 2: On a side note, does anyone know if it's possible to have a Javascript enlarging function for images, in which when one clicks on an image, it is enlarged, but either in a popup window that's smaller than the one behind it, and possibly centered, or by making the background go dark and then bringing up the enlarged image (is the latter done with Javascript; I have seen this effect for a while now and have always wondered.) |
