JavaScript - Highlighting Only The "last Link Visited"
. . My website with "ideas for education" will have two sitemaps -- a diagram, and a text-outline -- each located in the left i-frame, with links opening in the right i-frame. My homepage promises that each sitemap will "show where where you've been (green links), where you are (red highlighting), and where you can go (blue links) in your explorations."
. . The diagram-sitemap uses "swap images" (with code written by Dreamweaver) and 14 gifs, each with a red rectangle behind one of the 14 main links. (But it doesn't have green visited-links to show "where you've been.") . . In my text-sitemap, red-highlighting a visited link was easy, again by using DW's javascript tools. But this makes every visited link retain its red background, until the page re-loads. My goal is to red-highlight ONLY the last-visited link, to clearly show "where you are" in the sitemap. . . In one attempt to remove the red, I tried forcing a page-reload onMouseDown (with DW's "Go to URL") but DW refuses to recognize the sitemap's iframe (named "left") so it can only load the text-sitemap into a top-frame instead of the left iframe of its frameset. And this reload would be an awkward solution anyway, especially if a user has scrolled the page so the cursor would have to be moved back to the link for the onMouseUp part of clicking a link. . . A more elegant solution, found in a web-search, claims that "You can put an onclick event in all your links and then when the user clicks on a link, you can use the onclick event to call a function that changes that link's color to, say, green; and then uses the 'links' array to change all the other links to another color. The 'this' keyword can be used to identify the current link." . . This sounds promising, and JS-experts will see the two bold steps -- to "put..." and then "use..." -- and say "this is easy." But for me, doing these steps is a mystery I haven't solved. Some clues are below, gathered from various sources, but I don't know how to put it all together. A solution requires that everything is coded exactly the way it must be, with no mistakes, and I don't know how to do this. . . Here are some "pieces of the puzzle" that might be useful: . . Each sitemap has three areas, symbolized by colored page-backgrounds -- light blue & light green & yellow -- DDEEFF, DDFFEE, and FFFFBB. The js-code below, made in DW, works to change a link with red-background (from a previous link-click) to blue-background (onMouseDown) and back to red-background (onMouseUp). Code: <a href="blue1.htm" target="self" onMouseDown=" MM_effectHighlight (this, 1, '#DDEEFF', '#DDEEFF', '#DDEEFF', false)" onMouseUp=" MM_effectHighlight (this, 4000, '#DDEEFF', '#FF9999', '#FF9999', false)"> blue, then red</a> . . This works. But the challenge is to change OTHER links (not "this") from red to a color (blue, green, or yellow) that matches the page-background of the area where each link is. And for this I'm failing in two ways. First, I don't know how to make the link being clicked ("this") change the background-color of other links, by ""using the 'links' array to change all the other links to another color." Second, if I want to make three color changes (from red back to blue, or to green, or to yellow) the triple-change code below, which is the code above but with the onMouseDown line repeated 3 times, doesn't work in DW: [a comment added January 7: I've now abandoned this triple-change idea, and instead I want all links changed (onMouseDown) to a GOLD background-highlighting in a link-rectangle that surrounds each of the 14 main-topic links, but not the 40 sub-topic links.] Code: <a href="blue1.htm" target="self" onMouseDown=" MM_effectHighlight (this, 1, '#DDEEFF', '#DDEEFF', '#DDEEFF', false)" onMouseDown=" MM_effectHighlight (this, 1, '#DDFFEE', '#DDFFEE', '#DDFFEE', false)" onMouseDown=" MM_effectHighlight (this, 1, '#FFFFBB', '#FFFFBB', '#FFFFBB', false)" onMouseUp=" MM_effectHighlight (this, 4000, '#DDEEFF', '#FF9999', '#FF9999', false)"> blue-green-yellow, then red</a> . . Imagine that two links (blue0.htm, blue1.htm) are in a blue-background area of the text-sitemap, while two other links (2,3) are in a green-background area, and two links (4,5) are in a yellow-background area. By copying the code I found in another page, I think the code below might describe the links-array I want. But this raises two more problems: Third, the array probably contains errors or omissions. Fourth, even if it was correct, I don't know where to put it: in the head section? body section? inside the js-code for a link? if yes, would I have to repeat this code for each of the 14 main links, or should I write it once (with a name) and then "call up" this name for each of the 14 links. These are things an expert will know, but I don't. Code: <div class="box_broadstyle"><script> var linksArray = new Array(); links[0] = "blue0.htm"; links[1] = "blue1.htm"; links[2] = "green2.htm"; links[3] = "green3.htm"; links[4] = "yellow4.htm"; links[5] = "yellow5.htm"; </script></div> . . And I think the code below might be useful to make a "for loop" to control the triple-change by telling the browser which links (0 and 1) should have blue-highlighting (ending with #DDEEFF), and which (2,3) should end with green, and which (4,5) will be yellow. But... Fifth, I don't know if this code is correct or (a tougher challenge) where to put it so it will be functional. Code: for (y=0;y<=1;y++) for (y=2;y<=3;y++) for (y=4;y<=5;y++) . . Thanks for your patience in reading through this question, which is long because I've tried to clearly describe my goals and what I think might be parts of a solution. Any help in solving these mysteries (first, ... fifth) will be greatly appreciated. CraigR Similar TutorialsHello, I'm working on putting a partial lexicon of a language online and want to install a search bar at the top. The search should function sort of as "ctrl+f" by only picking up the entries that match with the search item. However, unlike an actual ctrl+f search, I don't want the matches to be highlighted one by one as the user has to continuously press "next." Instead, as soon as the user presses "search," all of the entries on the lexicon should disappear except those that match with the search term. Further information: I've mostly been using HTML and CSS to build this lexicon. All of my entries are in individual div elements and have individual div class names. Can anyone help, or refer me to an existing tutorial? Thanks! I 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! I'm building a t-shirt shop whose interface includes a gallery of designs in an IFrame. When the user clicks on a design, a dedicated page is loaded into the IFrame which shows all the available products associated with the design the user clicked. I've put each design's image and associated page as the first and second elements of a nested array, and am using a for loop to then load all the images into the page that's shown in the IFrame when the web-site loads. It's looking beautiful, but here's the rub I've been stuck on for two days now with no solution in sight... The array, "designImages", has 37 elements (ie. designImages[0]... designImages[36]). When I click on a design image on the page, any design image, the browser (all browsers, so I can't blame Microsoft for this one ), loads the page for design #36. I've tried all sorts of things, but still cannot tell if the issue is because the dynamically generated divs are being reassigned the value [36] after the for loop's executed, or if the div id's are okay but somehow the code is rooting for [36], the last element of the array anyway. I need someone's help in enabling a click on #4 to load the page for #4, etc, etc. Here's the code below. Thanks. Code:

Hey guys, This is my first time ever posting in a programming forum so please be nice! :) I'll admit right away that this is for a homework assignment, but I really did try to solve it myself before I decided to post here. The instructions are to have a confirm box pop up when links with the HTML class value "external" are clicked. If the user clicks "OK" they should be directed to the linked page. If they click "Cancel" they should not be directed anywhere. Here's my code: Code: function checkClass() {
var links = document.getElementsByTagName("a");
for ( var i = 0 ; i < links.length ; i++ ) {
var link = links[i];
if (link.className == "external") {
link.onclick = clickHandler();
}
}
}
window.onload = checkClass;
function clickHandler() {
if (confirm("You clicked an external link. Do you really want to leave this site?")) {
return true;
}
return false;
}
The problem is that the confirm box is triggered on page load and not on link click. I know I wrote Code: window.onload = checkClass; but how else should I call the function? I thought Code: if (link.className == "external") would keep it from going as far as to the confirm box until an external link was clicked. Thanks for pointing me in the right direction, Johanna Hello, how could I run an external (but still on the same server) ".js" file from a <a href> or a button? Is it possible and how? Thanks. If you need any details just ask. Hello, I run a online gaming website, and I'm having problems with certain websites iframing our games. 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 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? Hi all, I'm having a bit of a problem..

if its possible to make it do both in 1 function, please show an example. if you have to use 2 functions, then also show me an example. ANY help is GREATLY appreciated! First I have a performance question. Which would be better: Load a full table from the database first and display a portion with a "Show More..." link --OR-- Load just the small portion with a "Show More..." link and then do an ajax call to load the rest of the table? And secondly, I sort of know how to do the second option but it can get a bit complicated. You need to know the offset of which to search a database to load the rest. and the "append" that to the table. If I do the first option, it seems a bit more easier but I can't seem to come up with the logic. How would I truncate a table showing only a few entries and have the rest of the table hidden while having a link that shows the rest of the table when clicked? Thanks in advance. 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>

frameobj=document.getElementById('iframe').contentWindow;
// IE
frameobj.attachEvent('onpropertychange', function(){alert();} );
//FireFox
frameobj.addEventListener('input', function(){alert();} , false);

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 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 ... Here's my code .... In the <head> Code: <script type="text/javascript">
function getRBtnName(GrpName) {
var sel = document.getElementsByName(GrpName);
var fnd = -1;
var str = '';
for (var i=0; i<sel.length; i++) {
if (sel[i].checked == true) { str = sel[i].value; fnd = i; }
}
return fnd; // return option index of selection
// comment out next line if option index used in line above
// return str;
}
function chkrads(rbGroupName) {
var ExPg = [
[0,''],
[100,"1 extra page"],
[200,"2 extra pages"],
[250,"3 extra pages"],
[300,"4 extra pages"],
[350,"5 extra pages"]
];
var ExEm = [
[0,''],
[10,"1 extra email"],
[20,"2 extra emails"],
[30,"3 extra emails"],
[40,"4 extra emails"],
[50,"5 extra emails"]
];
var ImgBun = [
[0,''],
[10,"3 extra image"],
[20,"5 extra images"],
[30,"7 extra images"],
[40,"10 extra images"]
];
var rbtnGroupNames = ['extrapages','extraemail','imagebundles'];
var totalprice = 0;
var tmp = ''; var items = [];
for (var i=0; i<rbtnGroupNames.length; i++) {
tmp = getRBtnName(rbtnGroupNames[i]);
if (tmp != -1) {
switch (i) {
case 0 : totalprice += ExPg[tmp][0]; if (tmp > 0) { items.push(ExPg[tmp][1]); } break;
case 1 : totalprice += ExEm[tmp][0]; if (tmp > 0) { items.push(ExEm[tmp][1]); } break;
case 2 : totalprice += ImgBun[tmp][0]; if (tmp > 0) { items.push(ImgBun[tmp][1]); } break;
}
}
}
document.getElementById('QUOTED_PRICE').value = totalprice;
document.getElementById('ITEMS_SELECTED').value = items.join('\n');
document.getElementById('PRICE_IN_VIEW').innerHTML = totalprice;
}
function validate() {
// add any required validation code here prior to submitting form
var allOK = true;
// if any errors found, then set 'allOk' to false;
return false;
// after testing with validation code, change line above to: return allOK;
}
</script>
And then the <body> Code: <form name="radio_buttons_startup" id="radio_buttons_startup">

Thanks for your help in advance! 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. what is the meaning of this code? Code: <a href="#" onclick="ProjectNavigation.select(9494360);return false;">project</a> where wil it be linked since href ="#"? Code: for(i=0;i<document.getElementsByName('checkresult_".$i."').length;++i){
if(document.getElementsByName('checkresult_".$i."')[i].checked){
thisurlext+=document.getElementsByName('checkresult_".$i."')[i].value;
checkedlength++;
if(i+1<document.getElementsByName('checkresult_".$i."').length){
if(document.getElementsByName('checkresult_".$i."')[i+1].checked){
thisurlext+='+';
}
}
}
};

SOURCE: Here Code: 1 document.onmousemove = mouseMove;
2
3 function mouseMove(ev){
4 ev = ev || window.event;
5 var mousePos = mouseCoords(ev);
6 }
7
8 function mouseCoords(ev){
9 if(ev.pageX || ev.pageY){
10 return {x:ev.pageX, y:ev.pageY};

12 return {
13 x:ev.clientX + document.body.scrollLeft - document.body.clientLeft,
14 y:ev.clientY + document.body.scrollTop - document.body.clientTop
15 };
16 }
#1: How is it that "mouseMove" is assigned to "document.onmousemove" from right-to-left? What exactly is taking place here? #3: How can "mouseMove" be declared as a function afterwards? #3: I periodically see "e" being placed in functions. Is "ev" taking the place for "e"? If so is "ev" or "e" a global object? Where do they initially come from and how do they work? . All, So I have the following code. It works great. When I add this: Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> It doesn't work. I need it for some aspects of my CSS to work. The code that works without that is: Code: <html>
<script>
function resizeAll( )
{
var divs = document.getElementsByTagName("div");
for ( var d = 0; d < divs.length; ++d )
{
var div = divs[d];
if ( div.className == "fn-area" )
{
divid = divs[d].getAttribute("id");
imgid = "Img" + divid;
var Div1Width, Div1Height;
Div1Width = document.getElementById(divid).offsetWidth;
Div1Height = document.getElementById(divid).offsetHeight;
document.getElementById(imgid).style.width = Div1Width;

Hi, I am wanting to know exactly what happens when you create an ActiveXObject. At the moment all I managed to find out is that it will run the Program specified by the ProgID: Quote: This code starts the application creating the object (in this case, a Microsoft Excel worksheet). Once an object is created, you refer to it in code using the object variable you defined. http://msdn.microsoft.com/en-us/library/6958xykx.aspx Does it load the program like normal or does it load it within IE's memory? For example if the program crashes then why does IE crash. I would ask more questions but really I am sure there is more to it than simply loading the program. Thanks for any help in helping me get a better understanding. |
