JavaScript - Js Resize Text Like An Image
Hi,
I was wondering how to resize a div containing some text by setting a width and height so it would stretch to fill that area like an <img> tag? E.g. when you set the width and height attribute of an image, it resizes the image to fill that area. I do not wish to send a request to a php script to build an image containing the text since it will be slow and affect the scalability of the web app. Oh, and I would preferably not like to use html5 because it is a requisite that I need compatibility with ie7+ (and firefox/chrome). Thanks, akrylic Similar TutorialsHow do I resize a textarea to a certain length for text without the scroll bar, it this possible with CSS or do I have to use jQuery?
I was wondering if anyone knows of a javascript which re-sizes an image live as the user changes their browser window like the front page of the Louis Vuitton website? We would like it to fill the users browser window when they first load their page and then change size as they adjust their browser window. If not in javascript then if anyone knows of a flash script that would good, just prefer to just javascript. http://www.louisvuitton.com/ Thanks all Chris Can someone tell me how to veiw this eval's out put? PHP Code: function doButtons(picimage) { eval("document['picture'].src = " + picimage + ".src"); } PHP Code: <?php // to change the image size within the web page function imageResize($width, $height, $target) { //takes the larger size of the width and height and applies the formula accordingly... //this is so this script will work dynamically with any size image if ($width > $height) { $percentage = ($target / $width); } else { $percentage = ($target / $height); } //gets the new value and applies the percentage, then rounds the value $width = round($width * $percentage); $height = round($height * $percentage); //returns the new sizes in html image tag format... //this is so you can plug this function inside an image tag and just get the return "width='$width' height='$height'"; } ?> <HEAD> <SCRIPT LANGUAGE="JavaScript"> <!-- Original: Ronnie T.

I hope someone can help me with fixing this javascript code About the Code So I got this Resize Image Code here. This code is for a free Forum Software called Zetaboards (just like phbb or vbulletin). I just need to put the code in my Admin Control Panel to make it work for the whole forum. What does the code do? The code add a BBCode to the posting page, which allows all members to insert images to their posts (just like the usual "img" bbcode) and also makes it possible to resize the images. There are different resize image options: 1. [rimg]IMG_SRC[/rimg] // just inserts an image, like the normal "(img)(/img)" TAGS do. 2. [rimg=Width,Height]IMG_SRC[/rimg ] // with this option, you can change the width and height of the image. 3. [rimg=Percentage(needs % to be included)]IMG_SRC[/rimg] // Resize the image by typing the percentage size of the original image 4. [rimg=h,height]IMG_SRC[/rimg] //Just type the wanted height for the image, and the Width will be automatically adjusted 5. [rimg=w,width]IMG_SRC] //same as the code above, just the Height will be automatically adjusted instead. 6. [rimg=x]IMG_SRC[/rimg] //x will be both the height and width (so it'll be a square...) Here is a test thread I made to test the "rimg code", so you can see how the code works: http://s1.zetaboards.com/Piano2/topic/2874654/1/ What are the problems with the Code? - the Images are not resized correctly - sometimes, the images are resized correctly, but when i refresh the page, the images are again resized wrong. - or sometimes, when the images are displayed wrong (too big or small), they will become fine when i refresh the page again - In the Search View (when using the search) the images are too big and almost take the whole screen... - the first option "[rimg][rimg]" even doesn't work completely on IE and Google Chrome and causes all other [rimg] bbcodes to be disabled And finally this is the Javascript Code: PHP Code: <script type="text/javascript"> // Rimg by RedBldSandman of ZBCode.com $(function() { if (location.href.match("topic")||location.href.match("single")) { $(".c_post").each(function() { parse_rimg(this); }); } else if (location.href.match("search")) { $(".search_results").each(function() { parse_rimg($(this).children("div:eq(0)")); }); } else if (location.href.match("post")) { var rimg_br = ($("a:contains(Full BBCode List)").next().html()!=null)?"

Thanks for your answers and help! hi, which is the first code in javascript to load an image from my computer and then to automatically resize it to me ... as in the facebook thanks
Basically, i have an image that i want it to be resized when i maximize and change browser size, so it is always centered. I have to use only javascript. I tried many window.resize functions but nothing works. Lets say the image is called 0000.jpg. Anyone has any ideas how to make this? Thank you in advance. I am trying to write a custom BBcode for a forum I moderate. I don't have the licensing information because its not my forum and i am just a moderator. If anyone wants to verify the legitimacy of the forum I work for please PM me and I will try and get you any information I can. This code that I has works perfect in EditRocket, but when I add it to the custom BBcode the image does not resize. Original EditBucket Code: Code: <html>

I will have two text boxes that will accept numeric values and an image. What I need is if the user change the value of box 1, the value in box 2 will automatically update depending on the pixel dimensions of the image and vice versa. Basically I need to automatically calculate the pixel ratio of an image and then use that value to multiply by the user inputted size. Any ideas? Rob hello i'm building a search engine and one of the options i'm implementing is this: the user is able to control the scale of the thumbnail, small, medium and large the problem is that when i have 1000 pictures inside a div when i hit resize i get like a 5 sec delay for them to resize here is the javascript code: Code: Code: var factor;
function fillImg(imgPath, imgElement){
imageObj = new Image(32,32);
imageObj.src = imgPath;
if(imgElement.src != imgPath ){
imgElement.src = imgPath;
}
}
function errHandler(err){
alert("Error occured!");
}
function resizeImgList(scale){
if(scale == "s"){
factor = 50;
}else if(scale == "m"){
factor = 100;
}else{
factor = 150;
}
var lists = document.getElementById("rs_ls").getElementsByTagName("li");
for(var li_index = 0; li_index < lists.length; li_index++){
var canvas = lists[li_index].getElementsByTagName("span");
for(var c_index = 0; c_index < canvas.length; c_index++){
var link = canvas[c_index].getElementsByTagName("a");
for(var a_index = 0; a_index < link.length; a_index++){
var image = link[a_index].getElementsByTagName("img");
for(var i_index = 0; i_index < image.length; i_index++){
var w = $(image[i_index]).attr("width");
var h = $(image[i_index]).attr("height");
var results = resizeItem(w,h,factor,factor);
var w = results[0];
var h = results[1];
var m = results[2];
$(image[i_index]).attr("width",w);
$(image[i_index]).attr("height",h);
$(image[i_index]).attr("style","width:"+w+"px;height:"+h+"px;");
}
wa = w+12;
ha = h+12;
$(link[a_index]).attr("style","width:"+wa+"px;height:"+ha+"px;");
}
wc = w+12;
hc = h+12;
$(canvas[c_index]).attr("style","width:"+wc+"px;height:"+hc+"px;margin-left:"+m+"px;margin-right:"+m+"px;");
}
wli = w + 12 + m * 2;
hli = h + 12;
$(lists[li_index]).attr("style","width:"+wli+"px;height:"+hli+"px;");
}
}
function resizeItem(eWidth, eHeight, tWidth, tHeight) {
percentage = (tHeight / eHeight);
newHeight = parseInt(eHeight * percentage);
newWidth = parseInt(eWidth * percentage);
if (newWidth > tWidth) {
percentage = (tWidth / newWidth);
newHeight = parseInt(newHeight * percentage);
newWidth = parseInt(newWidth * percentage);
}
margin = (tWidth - newWidth + 12) / 2;
results = [newWidth, newHeight, margin];
return results;
}
each result set of 50 images has this structu HTML Code: Code: <span> <ul> <li>...</li> <li>...</li> <li>...</li> <li>...</li> . . . <li>...</li> <!-- 50 <li> --> </ul> </span> so 50 results are contained inside a span each <li> has this structure inside: HTML Code: Code: <li> <span> <a href...> <img> </a> </span> </li> I altered the resizeImgList function with 1 for loop but even then it didnt seem to improve. i was thinking that i could resize only the results the user is currently seeing inside the div, the current <span> of results but i'm anaware of how to accomplish this please if anyone has any idea I would be gratefull. Thank you. Peter. PS. results (spans) are fetched via AJAX on scrolldown inside the a div (which is the result container). Hi' there Is there anyway to make a custom resize function that resizes one of my div elements on the webpage the same amount of pixels as the browser window gets resized? Hi I have created the following effects on the images seen here http://techavid.com/design/test3.html . You see when you hover and then click on each image, they go from grey to color. When you click on one - the others go grey and the one clicked remains color. That's cool, but now I need the text 1st: Sun for example to display and hide along with its graphic button. The word "Sun," is a link that needs to link out to a URL so it has to be separated from the image effect code. Here code I have now.... Code:

What jquery or javascript code do I need to do this? thanks, chaser I need to replace the captions with simple text for download speed purposes. This is controlled by a piece of Javascript written for me. I need to change the caption image for a text one. The site is here Frank alias effpeetee. All, I'd like to have something similar to the rotating images and text on my website. The website that I would like to mimick is: http://www.photoworks.com/ You can see that the images move but there is still text over the image that I can click on. How would I go about doing something similar to this on my website. I'm guessing it's a combination of Javascript and CSS but I figured I'd start here. Thanks for any help in advance. i found a tutorial for doing the lightbox image viewer...and the link and demo is given below.. can someone tell me how do i replace the image with text in the lightbox....i mean when we hit on the image what shud i do to display text instead of image....hit on the image in the site and it will display an image.... http://www.dynamicdrive.com/dynamici...box2/index.htm thanx Hello! I am using this script for showing who is on the air. I would like to know if anyone has an idea how to make this show a picture file instead of text for who is on air. The script is great in that the gmt offset works. I would just rather have it show an image instead of text. Code: <span id = "dj" style="font-size:12px; font-weight:bold; font-family: Tahoma; color: #6600FF;"></span>

Hello everyone, I'm hoping that somebody can point me in the right direction. What I need to do is create a form which people enter text, and it displays over an image immediately on the same page. I have seen this done on so many different websites and can only assume that it's Javascript or Jquery that makes it work. I have seen it work where people enter the desired text, click update, and the text is then displayed over the image, but I've also seen it work where clicking update is not required, and the text is displayed automatically. If anybody can direct me to a script which does this, I'd be very grateful. Any help is appreciated! Many thanks, MG Code: function greet()
{
var hour = (new Date()).getHours();
var when = (hour > 17) ? "evening" : ( (hour > 11) ? "afternoon" : "morning" );
document.write('<img src="' + when + '.png" alt="Good ' + when + '">\n');}
This script puts up a png which gives a greeting depending on the time of day. I want instead to put the greeting as text. It's a bit ostentacious as it is.. I would appreciate any pointers. Site is here. Thank you. I've been looking for a reference to my situation for two days and i can't find any that are relevant enough. I'm trying to accept text as a URL for an image source. I then display that image in a form with the use of a <button type=button onclick=codeThatGeneratesImage > type thing. Code: function addImageToForm(formID) {
//get a reference to the form
var formElement = document.getElementById(formID);
//get a reference to the element that contains the url
var elementWithImageURL = document.getElementbyId("imageURLInput");
//get URL entered
var imageURL = elementWithImageURL.getAttribute("value");
//create image element
----------------------------------------------------------------------------------
var newImage = document.createElement("img");
//reference the source using the url
newImage.setAttribute("src", imageURL);
newImage.setAttribute("name", "newImage");
//append the image to form
formElement.appendChild(newImage);
}
i know that the bottom half works because i tried it with just a reference to an image directly and it worked. i can't figure out why most of the top part isnt working. any help would be much appreciated I am creating a photography website and am almost there with coding a very simple image viewer with clickable thumbnails etc. I have used the following script to change the images; Code: <script>
function changeImage(filename)
{
document.mainimage.src = filename;
}
</script>
the main image is like this; Code: <img name="mainimage" src="../Images/wedding-photo-01-bride-getting-ready.JPG" title="bride getting ready"/> And the links/images are like this..... Code: <a href="javascript:changeImage('../Images/wedding-photo-01-bride-getting-ready.JPG')">
<img class="thumbbox" id="mainimage" src="../Images/wedding-photo-01-bride-get-thumb.JPG" alt="wellis photography logo" title="bride getting ready">
</a>
This works fine, but I would also like a caption underneath the main image that changes at the same time. Is there a way to do this simply? Perhaps using some variation of the following script? Code: <script type="text/javascript">
document.write(document.getElementById('myimage').title);
</script>
Also, one other thing - is it possible to add a 'fade' transition to my 'changeimage' function? Thanks in advance First off thank you in advance to whomever decides to help out. I am having an issue where I am using lightbox, however what is showing up is a text link "Request Email." I understand how to manipulate this text to say anything I want. However, I am having difficulty changing the text link to an image. Instead of the text, I want to have an image (button) stored on my server http://www.something.com/something.jpeg be the link to click on instead of the text. It seems this would be easy to accomplish, but I cant figure it out. It anybody can send me in the right direction it would be appreciated. Thanks!
