JavaScript - Swap Image And Text, In Different Table Cells, On Click
Ok. I'm going to start by saying I'm a complete novice. I am having a hell of time finding specific codes for the things I need. I'm pretty impressive I've gotten this far. So I am trying to make a portfolio website, for myself, which has thumbnails on the left(which I'll crop in photoshop because it is easier for me than having to do any coding) which will make the main image on the right change. At the same time, I want it to change the text below to correspond to the current image. Now I have the images swapping alright, except that the thumbnails that have the onClick function in them won't sit inside the table I have inside the table. I don't understand why that happens. I can work around this, and just get rid of that table. Another problem is that even though I defined the collumns as each being 20%, they are not all the same size. I am using percentages so that the site will function regardless of screen resolution.
Anyway, here is my current code. Ignore the image names, I'm just using what random images I have at hand while I test things out. Code: <html>
<head>
<script type="text/javascript">
function swap(image) {
document.getElementById("main").src = image.href;
}
</script>
</head>
<body>
<table width="80%" align="center">

<td width="20%"><center>Photo</center></td>
<td width="20%"><center>Misc</center></td>
<td width="20%"><center>Resume</center></td>

Similar TutorialsOK. I'm super new to any kind of java script. What I want is a menu that, when clicked, changes the background color of a table cell to blue. When a different option is clicked, the current highlighted table should turn back to gray and the new selection should be blue. Well, I have all of that working. What I need now is just to have the first option start out highlighted and to become unhighlighted when another option is clicked. Any help would be awesome!!!! Thanks!!!!!! Code: <html>

So I want to swap an image when it's clicked on (and then swaps right back after release) and currently I have working code for this, HOWEVER (and the reason for my post) I want this to be a redundant image, so it would be the same image used about 25 times on the page (same image, with same image swap effect) it's basically a download button then slightly changes it's style when clicked on. The problem is that my current code requires me to give each image it's own specific id / name and I have to recreate more sript code for each image id as well. The following example code would be what is currently required for just 2 images (they are the exact same image with exact same swap) but as you can see for every additional download button on the page I have to add a new id for it and a bunch of additional code, so it's quite ridiculous as to how much code is required for 25 of the exact same images on the page. in the header I have: Code: <script language="JavaScript">
<!--
// PRELOADING IMAGES
if (document.images) {
downloadbtn_down=new Image(); downloadbtn_down.src="images/download_pressed.png";
downloadbtn_up =new Image(); downloadbtn_up.src ="images/download.png";
}
if (document.images) {
downloadbtn2_down=new Image(); downloadbtn2_down.src="images/download_pressed.png";
downloadbtn2_up =new Image(); downloadbtn2_up.src ="images/download.png";
}
// EVENT HANDLERS
function pressButton(btName) {
if (document.images)
eval('document.'+btName+'.src='+btName+'_down.src');
}
function releaseButton(btName) {
if (document.images)
eval('document.'+btName+'.src='+btName+'_up.src');
}
//--></script>
and for each image in the body I have (example is for 2 images): Code: <a href="indexpg.htm"
onMouseDown="pressButton('downloadbtn');return true;"
onMouseUp="releaseButton('downloadbtn');return true;"
onMouseOut="releaseButton('downloadbtn');return true;"
onClick="return true;"
><img id=downloadbtn width=422px height=80px border=0
alt="Download"
src="images/download.png"
></a>
<a href="indexpg.htm"
onMouseDown="pressButton('downloadbtn2');return true;"
onMouseUp="releaseButton('downloadbtn2');return true;"
onMouseOut="releaseButton('downloadbtn2');return true;"
onClick="return true;"
><img id=downloadbtn2 width=422px height=80px border=0
alt="Download"
src="images/download.png"
></a>
I want to be able to just use the same piece of code without having to add a new id for every download button on the page and tons of redundant code, especially since the image is the same it doesn't make sense to have to give each one a specific id and specific javascript for each of those id's. I would think this would be quite simple, but I know nothing about javascript, and I have searched a lot without any luck. PLEASE HELP ME! Hi, I'm very new to coding Javascript, so have no idea what I'm doing, so sorry What I'm trying to do is, on my Wordpress Blog I have a button/Image: Code: src="http://Mysite.com/Images/Button.png" I would like for when a user Clicks this Image/button, 2 things to happen - 1. For my Content Locker to pop up, I believe that i already have the correct code for that?: Code: onclick="var fileref=document.createElement('script');fileref.setAttribute('type','text/javascript'); fileref.setAttribute('src', 'http://MYCONTENTLOCKER.com/guid?:1234567890')
For this content locker to trigger, The whole action needs to have a ID e.g. 'ID="button1'? And 2. For a timer to start for say 30 Seconds. When that timer ends, i would like the original button/image to be replaced with a different button/image. And when that New button is clicked i would like a text string to appear below the button - saying something e.g. 'You've completed this part' I know that this is a lot to ask, and I will be so very grateful if someone helps me out here! Thanks! Harry. 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:

This is my code. Now i have problems with the eraseImage and drawImage functions. They just don't work. Any help will be appreciated. Thank you Hi all, First post here in a long time, I'm finally getting round to sorting out a portfolio website. I have a rollover image which has a mouse over and down action and a table cell which has a mouse over and down action which swaps the assigned css class. What i need to happen is when i mouse over the table cell containing the rollover image the table cell below switches the style assigned to it. I have it working the other way around so when you mouse over the bottom cell the image in the top cell swaps, see he http://onebitrocket.co.uk/swapimageandtext.html I'm basically looking for an action similar to a swap image in a cell which has it's ID defined onmouseover="MM_swapImage('Image4','','images/thumbs/th04.jpg',1)" so onmouseover="MM_swapstyle... Any help would be great Thanks New to JavaScript so PLEASE bear with me. Trying hard to learn. My client specifically asked for a type of menu (scroll over a thumbnail and you see a large photo in the column next to it. And of course the thumbnail is clickable to new page. I am using this Jeremy Keith script: PHP Code: /* This script and many more are available free online at The JavaScript Source!! http://javascript.internet.com Created by: Jeremy Keith / Anonymous | http://www.alistapart.com/articles/imagegallery/ */ function showPic(whichpic) { if (document.getElementById) { document.getElementById('placeholder').src = whichpic.href; if (whichpic.title) { document.getElementById('desc').childNodes[0].nodeValue = whichpic.title; } else { document.getElementById('desc').childNodes[0].nodeValue = whichpic.childNodes[0].nodeValue; } return false; } else { return true; } } var previousToggle=null; function toggleMe(a){ var e=document.getElementById(a); if(!e)return true; if(e.style.display=="none"){ e.style.display="block"; if(previousToggle)previousToggle.style.display="none"; previousToggle=e; } return true; } and it works fine, except that I can't figure out how to make it showpic on mouseover and still go to new URL (basic link to a page) onclick. Here's a link (one of 8)in the body: PHP Code: <a onmouseover="toggleMe('para1'); showPic(this); return false;" href="design.html" title="blah blah blah"> <img src="images/pix_smaller3.jpg" width="70" height="70"></a> It either links to new page with the href="design.html", or swaps in larger pic if I href to the img file, but I can't seem to get BOTH to work. I obviously want the <a> to be to a new page, not the larger img. Shouldn't showPic take care of this? Where is showPic getting its imgs from? I know that this can't be that complicated, but I have been up for 2 nights trying to figure this out. Any help appreciated... I have a small snippet of code which will copy the contents of a textbox to the clipboard when a small image, say a button, is clicked. I want to achieve a similar effect when I click a hotspot on an image, but in this case the text will have to come from...well, I don't know. Maybe the title in an area tag? This is what I have so far for a textbox: Code: //clipboard copy
function ClipBoard(what){
Copied = document.getElementById(what).createTextRange();
Copied.execCommand("Copy");
alert ("Information copied to the clipboard. Use CTRL-V to paste.");
}
<textarea id="holdtext1"></textarea> <img border="0" src="copyclick.gif" onclick="ClipBoard('holdtext1');" alt=" Click to copy text to clipboard / CTRL-V to paste" style="cursor: hand" width="18" height="18">

Hey. so, I know how to add the row, and cells, I did that...except now I need to add properties to the cells (class, ID, onclick etc)...just wondering how I go about doing that. Here is what I have so far: Code: function add_new_proj(){
new_proj_id = prompt("What would you like the new Project Number to be?","xxx-xxxxx");
var table=document.getElementById('projectDisplay').insertRow(1);//creates a var which adds one row to the table
//the variables are finding the correct cell to enter the data into the new row (based on an array 0 based system)
var projectID=table.insertCell(0);
var ProjectName=table.insertCell(1);
var Client=table.insertCell(2);
var ClientProjectID=table.insertCell(3);
var delete_cell=table.insertCell(4);
projectID.innerHTML = new_proj_id;
ProjectName.innerHTML ="";
Client.innerHTML = "";
ClientProjectID.innerHTML = "";
delete_cell.innerHTML = "<span class='delete' id='$ProjKey-d' onclick='delete_edit_proj(\"ajax_modify_proj.php\",this.id)'> Delete </span>";
}
this is an example of what the cells look like (the ones that already exist, generated via PHP code): PHP Code: echo "<td class='projectTd' id='2tdName-$j' onclick='editTd(this.id);'> $ProjName </td>"; So yeah..I need the new cells to pretty much look like that >.< with a class, id, and onclick event. any help would be great! thanks Hello, I'm Stephen Martin, an undergraduate Psychology student and researcher. Although I am a self-proclaimed tech geek, the extent of my knowledge ends abruptly at any sort of coding. I need help from anyone who is willing. The paradigm: I am currently investigating the decision making strategies in a particular population (I cannot reveal too much, lest our study be scooped by competing researchers in the field). The paradigm that we use is built through a package called MouseLabWeb (http://www.mouselabweb.org/). MLWeb basically provides an interface for researchers to create a html/php/js/css website that presents a grid (table). A small example is shown on the aforementioned website. The javascript functions allow each participant's events to be recorded, timestamped, and written to a MySQL database. This allows the researcher to know which cells the participant viewed, in what order, for how long, and ultimately to which decision the participant came. Additionally, the PHP/HTML creates the table, but the data within it is populated by the javascript. This is a blessing and a curse. Here is why. The problem: The javascript offered by MLWeb allows the cells to be randomized. This is necessary, because in such paradigms, counter-balancing is required, otherwise there would be order effects (e.g., people tend to automatically read from the upper left) that are not controlled for. So the order of the columns and rows are randomized, the data which is then placed into the html/php table. For the current study, we want the cells corresponding to particular types of information to be shaded differently. For example, we'd want cells that contain bad information to be dark, cells that contain neutral info to be grey, and cells that contain good information to be white. The problem is that setting these values (style="background-color: #XXXXX) only applies to the table as created by the PHP. It only affects the position, and does not consider the information that it is filled with. We want the information that a cell is filled with to dictate what background-color the cell is. Example of the problem (A,B,C are the different types of info, with the surrounding character implying shading) What we want: Unrandomized: [.A.] [|B|] [#C#] Randomized: [#C#] [.A.] [|B|] What the problem is: Randomized: [.C.] [|A|] [#B#] Again, thank you for reading this long post. I'm up for any suggestions! TL;DR The website uses PHP to render a table and javascript to populate it. Javascript randomizes the column and row order upon each visitation, thus randomizing the cells. How do I make javascript issue a background-color change to each cell according to the information that it is populated with. My apologies if this request is vague, but I am not completely certain what the terms are for what I am asking. So I will include a link to an example: http://www.v12groupinc.com/ Below the flash banner, there is a row of tabs that below display different text when you mouse over each. If you move the cursor away, the text of the last mouse-over stays (as opposed to defaulting to something else). It is the closest example to what I'd like to do but don't really know what it is to look for in terms of assistance. Essentially I want to make a set of 3 graphic rollover tabs that each have different text attached to them. I would like for the tab to rollover and the text to change when mousing over each (the first one would be the default of course). However I would also like for the last tab that was moused over's text to remain when the cursor is moved away. With various tutorials online I've been able to create a text based one that unfortunately resets to default on mouseout and to which I haven't been able to add rollover images to. If anyone can point me to a tutorial, enlighten me to what terms to search for, or even give me some code to start with, I would be most grateful. Thanks! Is it possible to create a text hyperlink with 2 different font colours in one word e.g. Hyper link so that the colours swap over when the mouse is placed over any part of the link i.e.. Hyper link . ? Using #FF6600 for orange and #006600 for green and by setting the css as follows: .graph a:link { color:#FF6600; text-decoration: none; } .graph a:visited { color:#FF6600; text-decoration: none; } .graph a:active { color:#FF6600; text-decoration: none; } .graph a:hover { color:#006600; text-decoration: none; } and then by applying a javascript rollover using a span inside the link I have been able to make one side of the link behave as desired, but not both sides. <span class="graph"><a title="graph" href="vml/patterdale-swirral-edge.htm">Hyper<span class="grn" id="span1" onmouseover="this.style.color='#FF6600'" onmouseout="this.style.color='#006600'">link</span></a></span> I would prefer to use just css, but a solution with javascript would be equally appreciated. Hi I am trying to make all the cells within a table droppable spaces, using the scriptaculous library. However I am not able to do so, and I am not certain why. The table cells are creating within the javascript. I then try to apply the droppables to the table cells through iteration, through the function when the document loads. It does not seem to be working. The document accesses an external php page and has inline php within a div element. I am uncertain if by having the draggable elements instantiated within the php script, that this would be causing any problem, as I cannot see how this would be, the php draggables all appear to be corresponding to the css in the document. Any help with the droppables would be appreciated. I have set up a css class hover, so that when the draggable passes over the droppable the edges of the droppable area should be turning blue, but this is not happening. Not sure what the problem is.

So I am using JavaScript to make a table on a page and what I want to do is have the JavaScript create the table, and then allow the user to fill it with data. I have been able to make the JavaScript create the table, my question is how to reference the cells in my script that adds data to the cell. I want the users to be able to click a button an add data into different cells so i figured giving them each an Id and referring to that Id in the button is the best way to do it. How can I edit my code to give each cell a different Id? Or is there a better way of doing this? My table code looks like this (i have filled it with random data so it is not just a blank table). <code> <script type="text/javaScript"> window.onload = fnInit; function fnInit() { // Declare variables and create the header, footer, and caption. var oTable = document.createElement("TABLE"); var oTHead = document.createElement("THEAD"); var oTBodyam = document.createElement("TBODY"); var oTBodypm = document.createElement("TBODY"); var oTFoot = document.createElement("TFOOT"); var oCaption = document.createElement("CAPTION"); var oRow, oCell; var i, j; // Declare stock data that would normally be read in from a stock Web site. var heading = new Array(); heading[0] = ""; heading[1] = "Monday"; heading[2] = "Tuesday"; heading[3] = "Wednesday"; heading[4] = "Thursday"; heading[5] = "Friday"; var block = new Array(); block[0] = "8:30"; block[1] = "9:55"; block[2] = "11:20"; block[3] = "12:45"; block[4] = "2:10"; block[5] = "3:35"; block[6] = "5:00"; block[7] = "6:30"; var stock = new Array(); stock[0] = new Array(block[0],"88.625","85.50","85.81","99.54","55.46"); stock[1] = new Array(block[1],"102.75","97.50","100.063","49.54","55.46"); stock[2] = new Array(block[2],"56.125","54.50","55.688","99.54","55.46"); stock[3] = new Array(block[3],"71.75","69.00","69.00","99.54","55.46"); stock[4] = new Array(block[4],"71.75","69.00","69.00","99.54","55.46"); stock[5] = new Array(block[5],"71.75","69.00","69.00","99.54","55.46"); stock[6] = new Array(block[6],"71.75","69.00","69.00","99.54","55.46"); stock[7] = new Array(block[7],"71.75","69.00","69.00","99.54","55.46"); // Insert the created elements into oTable. oTable.appendChild(oTHead); oTable.appendChild(oTBodyam); oTable.appendChild(oTBodypm); oTable.appendChild(oTFoot); oTable.appendChild(oCaption); // Set the table's border width and colors. oTable.border=1; oTable.bgColor="lightslategray"; // Insert a row into the header and set its background color. oRow = document.createElement("TR"); oTHead.appendChild(oRow); oTHead.setAttribute("bgColor","lightskyblue"); // Create and insert cells into the header row. for (i=0; i<heading.length; i++) { oCell = document.createElement("TH"); oCell.innerHTML = heading[i]; oRow.appendChild(oCell); } // Insert rows and cells into bodies. for (i=0; i<stock.length; i++) { var oBody = (i<3) ? oTBodyam : oTBodypm; oRow = document.createElement("TR"); oBody.appendChild(oRow); for (j=0; j<stock[i].length; j++) { oCell = document.createElement("TD"); oCell.innerHTML = stock[i][j]; oRow.appendChild(oCell); } } </code> Writing Table Cells and Switch Statements I am to create a function and purpose is to write blank tables cells to make up horizontal bar. function will have 2 parameters=(partyType and percent partyType parameter stores variables of D,R,I,G or L percent parameter store percentage rounded to nearest integer so I am to make a switch and break statements /commands then have to create a For Loop in counter variable goes up from 1 through value of parmeter increments of 1 heres the code I created for this one Code: function createBar(partyType,percent){ // script element to create blank cells
switch(partyType) {
case "D": document.write("<td class='dem'></td>");
break;
case "E": document.write("<td class='rep'></td>");
break;
case "I": document.write("<td class='ind'></td>");
break;
case "G": document.write("<td class='green'></td>");
break;
case "L": document.write("<td class='lib'></td>");
break;
}
var barText = partyType
for (i=0; i < percent; i++)
{
document.write(barText);
So what improvements should I make? should my loop be before everything? Thanks |
