JavaScript - Drop Image
If you open two tabs, http://www.google.com/imghp and another one, you are able to drag and drop an image from the other tab to the google search tab, and google will search similar images.
i can't figure out how that works, does anybody know how? Similar Tutorialsi've got a drop down menu and an image fader. i need the drop down menu to overlay on top of the fader. currently it drops down under it. i've tried messing about with z-index but not getting far. any ideas? thanks http://www.thebluebus.co.uk/tempwest/ I would appreciate some help, I want to use the Drop Down Image selector II script on a website, to display fabric, as there is a large number of samples, I want to break the list up alaphabetically. Is is possible to use the script more than once on a page, when I tried to do this the script did not work, if it can not be used more than once on a page, has anyone seen a program that could be. Thanks I'm currently setting up a website that will display, for each link in the drop down, an image below the box, and text or, if necessary, an image to the right, describing the item & listing materials & prices. I've tried iframes with a drop down, but because I'm hosted with BraveHost, I end up with 50 ads on the main page, and 50 more in the iframe, so I'd like to avoid that if possible. If you want to see what I'm looking for, go here. http://andicrafts78.bravehost.com/test.html. How can I modify the drop down selector to make it happen?
I have a drop down menu and an image slider that both use javascript code to function. The image slider appears right below the menu but when the actual menu drops down, the drop down part of the menu goes behind the image slider. How do I make it so that the menu drops above the image slider and not behind it? Hello All, I am trying to find a solution for this ..... kindly help incase you know.... I need a drop down menu to appear when I left-click an image.... have tried a lot but failed... Please help me out on this Thanks in advance,,, Regards Hi all, I hope you are able to help me out. I have a a page (see code below, I have compressed it to 2 images) where I want to let the user drag and drop images to anywhere on the page (I have achieved this.) What I want to be able to do is allow the user to dock 2 images together. In the example below the 2 images are horizontal lines. What I want the user to be able to do is move the images together and dock them so that they form one horizontal line. When the user moves one of the pictures both will move and stay docked. my initial idea was that when the user selects "dock" I somehow move both images into a div and make the div dragable, that way both images move together. Then if the user selects "undock" both images are removed from the div and become draggable again. I hope this makes sense. Can anyone help?

Anyone know? Something similar to the navigation menu on http://www.gamewearteamsports.com/. You hover over a link and a box appears below that spreads the width of the menu itself. Friend of mine told me it was using actionscript but I have no idea how to create a drop down box (not menu). Any ideas? My friend told me Dreamweaver has the ability t create a drop down box but I have no idea. Also does anyone know how to create an image slider similar to the one on that site? A slider that fades from one image to the next with the navigation arrows on the left and right side and the dots on top left? I have added "Swap Image" into a page which already has a Drop Down Menu. However the Drop Down Menu stopped working. I know I have to remove the last line from the Drop Down Script ...window.onload=startList;... and integrate it into the <body tag> but I can't seem to figure it out. Someone please help... Below is the script for the drop down menu. // JavaScript Document startList = function() { if (document.all&&document.getElementById) { navRoot = document.getElementById("nav"); for (i=0; i<navRoot.childNodes.length; i++) { node = navRoot.childNodes[i]; if (node.nodeName=="LI") { node.onmouseover=function() { this.className+=" over"; } node.onmouseout=function() { this.className=this.className.replace(" over", ""); } } } } } window.onload=startList; Here is the page I'm trying to work with. http://sigautoparts.com/home-test.htm I saw this on the web the other day and didn't mark the page I found it on. How do I change an image based on what selection is made in a drop down? Kathy I have a problem with a drop down menu showing behind image slider (not flash), as the menu shows up behind the large image slider, and was hoping someone can help me: http://bedrockstoneanddesign.com/ It only happens in FireFox..... any help is appreciated. thanks all i have to do is the image to change automatically based on the option you selected from the drop down list. here is the code, any help is appreciable. thanks in advance. <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"> <style type="text/css"> img{ height:95px; width:95px; display:block; margin-top:10px; } #caption{ font-family:Verdana,tahoma,arial; font-size:8pt; text-align:left; display:block; width:250px; } </style> <script type="text/javascript"> window.onload=function() { var caption=['Default Image Caption', 'begonia', 'daffodils', 'mixture', 'natural', 'purple', 'red flower', 'sunflower', 'tulip', 'two flowers'], // This will be your images caption bp='..\images', //base url of your images imgnum=9, //Number of your images.

You know when you click the file option in your browser's toolbar, and a drop down menu appears? It can be just like that, but instead of save as and open, links will be there to places within our intranet opened in a new window. This has to work for IEX 7+ because that's all our company decides to use. I tried to submit a chang erequest for them to move to a better CSS/Javascript supportive browser such as Opera, Firefox, Google Chrome... but they're way too fixed on IEX for some odd reason. I am obliged for any help on this. *edit* colors dont matter. It can be the default colors used in a basic drop down menu. I figure javascript would have more options though. I have been searching for a long time but have been unsuccessful on how to develop a drop down menu but have the menu items show in a list above the main nav. Not below. I really like the way this functions: http://www.sohtanaka.com/web-design/examples/toggle/ But I would like the item in the list to appear above the main nav so it animates up not down. Can anyone help me on how to alter this js code to perform this task? Here is the jQuery file link: http://code.jquery.com/jquery-latest.js I tried going through this js file but it very complex. Can anyone tell me what I need to change to have the animation roll up instead of down? Any help would be most appreciated. Hello everyone! So, what it does: You can successfully drag something anywhere, but when you click it again, it resets to its original position (I don't know why), and when you try to drag it again, as soon as your cursor touches the object it disappears (I don't know why). I'm hoping someone can tell me why it is happening and how to fix it! Code: // JavaScript Document
var posX;
var posY;
var element;
function drag(event) {
element = document.getElementById("square");
posX = event.clientX;
posY = event.clientY;
element.addEventListener("mousemove", move, false);
}
function move(event) {
if (typeof(document.getElementById("square").mouseup) == "undefined")
element.addEventListener("mouseup", drop, false);
//Prevents redundantly adding the same event handler repeatedly
element.style.left = event.clientX - posX + "px";
element.style.top = event.clientY - posY + "px";
}
function drop() {
element.removeEventListener("mousemove", move, false);
element.removeEventListener("mouseup", drop, false);
}
the html is a simple (position is set to relative): <p id="square" onmousedown="drag(event)">meep</p> Lastly, and most importantly, thank you all for your time =] EDIT: This is the first time I've written javascript code and would like to learn the basics, which is why I am not using a library. Hello there, CodingForums.com! I'm a newbie to Javascript, HTML, XHTML, CSS-- and oh god, everything, so please bear with me! I have come to understand that to get any better, I'll need support. I hope you guys (and gals) can assist! Here is my issue: I'm currently trying to develop a first-draft calculator that will allow me to calculate some values for work and the way I want it requires me to do it with a pair of drop-downs. Take a look at it he http://www.projectvoid.co.uk/ I would like to select the first drop-down, on the left-hand side (Current Lighting Products -> Type of Lamp) and for the right-hand side to copy it's selected value (Energy Efficient Products -> Type of Lamp). Furthermore, it shouldn't interfere with the fact that I'm also using those values with my dependent drop-down, below (Wattage). The only piece of code I've found that might help is this: Code: function setSelect(name1, name2)
{
var select1 = document.forms.formname.elements[name1];
var select2 = document.forms.formname.elements[name2];
select1.selectedIndex = select2.selectedIndex;
}
I am also unsure how to utilize it. I look forward to your aid! Thank you in advance. Okay, I'm having some trouble getting my head around how to do this.. Code: <select> <option value="A">A</option> <option value="B">B</option> <option value="C">C</option> </select> <select> <option value="Rhino">Rhino</option> <option value="Bird">Bird</option> <option value="Rooster">Rooster</option> </select> <select> <option value="0202A">Rhino - Text</option> <option value="0203A">Rhino - Text2</option> <option value="0204A">Bird - Text1</option> <option value="0205A">Bird - Text2</option> <option value="0202B">Rhino - Text</option> <option value="0204B">Rhino - Text2</option> <option value="0204C">Rooster - Text1</option> <option value="0205C">Rooster - Text2</option> <option value="0206C">Rooster - Text3</option> </select> So say we had those three drop-downs. I'm looking to make it so that second drop-down only has options corresponding to a relationship between the first and the third drop-down. Example - if you select A in the first drop-down you only see Rhino and Bird in the second drop-down. If you select B you will only see Rhino in the second drop-down. Lastly, if you select C you will only see Rooster in the second drop-down. Just can't figure this out. >.< I know how to edit the CSS, and minute parts of the JavaScript code (for example; speed of the drop). The problem is, I had a massive amount of help making the Javascript side of the menu, and do not know how to edit it... I want the rules to still apply, where only one can be expanded at a time (one of the first drops, and then only one of the sub-drops). I noticed in the code, I can edit it so there can be more than one drop, but that would mean, the whole menu could be expanded Also, I want my sub-drops. to have different span colour than the main drop. but trhe links and such, (everything else about it) can be the same.... My live demo is here! Thank you for any help and/or advice in advance, Best Regards, Tim i have image button i need to display image .if the size of the image button is 100*100 and image size is 50*50 .the remaining space of the image button should be empty.the image should not stretch. can any one guide me i am new to programming Thanks in advance!!! |
