Similar TutorialsI have 5 divs fading in a slideshow with the crossfade js. This basically fades the opacity of each div and loops the 5 divs so that it continues to fade from the 5th to the first and so on... Is there a way for me to end the fade at the 5th div so that it does not loop? Here is the code for the JS: // JavaScript Document // CrossFader var x; if (x) { if (typeof(cf) == "undefined") var cf; } else { var cf = this; } cf.fader = function (obj, fadetime, delay) { this.el2 = -1; this.id = obj; for (i=0; i<obj.length; i++) { var s = document.getElementById(obj[i]).style; s.position = "absolute"; s.visibility = "hidden"; s.opacity = 0; s.filter = "alpha(opacity=0)"; } this.dur = fadetime; this.delay = delay; this.fade2(); } cf.fader.prototype.fade1 = function() { this.time += this.interval; var ieop = Math.round(this.fade(this.time, 0, 1, this.dur) * 100); var op = ieop / 100; var s = document.getElementById(this.id[this.el2]).style; s.opacity = op; s.filter = "alpha(opacity="+ieop+")"; if (this.el1 > -1) { var s = document.getElementById(this.id[this.el1]).style; s.opacity = 1 - op; s.filter = "alpha(opacity="+(100 - ieop)+")"; } if (this.time == this.dur) { clearInterval(this.id1); if (this.el1 > -1) document.getElementById(this.id[this.el1]).style.visibility = "hidden"; var t=this; this.id2 = setInterval(function() {t.fade2()}, this.delay); } } cf.fader.prototype.fade2 = function() { if (this.id2) clearInterval(this.id2); this.el1 = this.el2; this.el2++; if (!this.id[this.el2]) this.el2 = 0; if (this.el2 == this.el1) return false; document.getElementById(this.id[this.el2]).style.visibility = "visible"; this.interval = 50; this.time = 0; var t=this; this.id1 = setInterval(function() {t.fade1()}, this.interval); } cf.fader.prototype.fade = function(t,b,c,d) { return c/2 * (1 - Math.cos(Math.PI*t/d)) + b; } and here is the html markup: <div id="fader"> <div id="fade1"> <h1>1</h1> </div> <div id="fade2"> <h1>2</h1> </div> <div id="fade3"> <h1>3</h1> </div> <div id="fade4"> <h1>4</h1> </div> <div id="fade5"> <h1>5</h1> </div> </div> <script type="text/javascript"> // ids, fade length, display time var fadeIt = new fader(new Array("fade1", "fade2", "fade3", "fade4", "fade5"), 2000, 4000); </script> Any help on how to end the loop would be greatly appreciated!!! Hi, I've found this forum a really useful resource for solving my JS queries I've had in the past, but up until now I've never needed to post. Over at my personal tumblog, http://andbamnan.tumblr.com, I have implemented both 'J' 'K' key navigation (on Chrome and Safari only) and infinite scrolling. However, I've found that the two scripts don't work so harmoniously together, as the key navigation from post-to-post doesn't go beyond the first page, instead scrolling up to the first post of the first page. Chrome or Safari users can experience what I'm trying to describe by clicking on the link above and hitting 'J' to browse down or 'K' to browse up. I hope there is a solution for this, or if possible, a script out there that CAN conquer both commands. Thank you Ok, I'm nearly pulling my hair out with this one. I have been looking at this code for two evenings now, and rewrote it 4 times already. It started out as jQuery code and now it's just concatenating strings together. What I'm trying to do: Build a menu/outline using unordered lists from a multidimensional array. What is happening: Inside the buildMenuHTML function, if I call buildMenuHTML, the for loop only happens once (i.e. only for 'i' having a value of '0'.) If I comment out the call to itself, it goes through the for loop all 3 times, but obviously the submenus are not created. Here is the test object: Code: test = [
{
"name" : "Menu 1",
"url" : "menu1.html",
"submenu" : [
{
"name" : "menu 1 subitem 1",
"url" : "menu1subitem1.html"
},
{
"name" : "menu 1 subitem 2",
"url" : "menu1subitem2.html"
} ]
},
{
"name" : "Menu 2",
"url" : "menu2.html",
"submenu" : [
{
"name" : "menu 2subitem 1",
"url" : "menu2subitem1.html"
},
{
"name" : "menu 2subitem 1",
"url" : "menu2subitem1.html"
} ]
},
{
"name" : "Menu 3",
"url" : "menu3.html",
"submenu" : [
{
"name" : "menu 3 subitem 1",
"url" : "menu3subitem1.html"
},
{
"name" : "menu 3 subitem 1",
"url" : "menu3subitem1.html"
} ]
}
];
Here is the recursive function: Code: function buildMenuHTML(menuData,level) {
var ul;
if (level == 1) {
ul = "<ul id='menu'>";
} else {
ul = "<ul class='level" + level + "'>";
}
for (i = 0; i < menuData.length; i++) {
menuItemData = menuData[i];
ul += "<li>";
ul += "<a href='" + menuItemData.url + "'>" + menuItemData.name + "</a>";
if (typeof menuItemData.submenu != 'undefined') {
ul += buildMenuHTML(menuItemData.submenu,level + 1);
}
ul += "</li>";
}
ul += "</ul>";
return ul;
}
Here is how the function is called initially: Code: buildMenuHTML(test,1); This is it's return value (with indentation added for readability): Code: <ul id='menu'>
<li><a href='menu1.html'>Menu 1</a>
<ul class='level2'>
<li><a href='menu1subitem1.html'>menu 1 subitem 1</a></li>
<li><a href='menu1subitem2.html'>menu 1 subitem 2</a></li>
</ul>
</li>
</ul>
'Menu 2' and 'Menu 3' don't show up! I'm sure it's something small that I'm overlooking, but any help would be appreciated. Hi all I'm well aware that I can't post assignments here and expect an answer, however, I have been staring at this code for so long. I feel I am close to the solution (to get the correct output to the browser) but I just cannot get it to count how many moves it takes. I don't want an answer, but a nudge in the right direction would be very grateful. As you can see from the code and the output, it will attempt to write to the browser how many moves, but only '0'. Code: function rollDie()
{
return Math.floor(Math.random() * 6) + 1;
}

*searches for a number in a number array.
*

* the number to search for
* the number array to search

{
var indexWhereFound = -1;
for (var position = 0; position < numberArray.length; position = position + 1)
{
if (numberArray[position] == number)
{
indexWhereFound = position;

Many thanks. Hello... Thanks for reading... I am getting an undefined error when i try to get a value from this array in the interior loop... Code: // This is the array I am trying to access AuditTable [0] = ["Visio Modifed date","Word Modified Date","User Status","User Comment","Last Audit","Audit Status","Audit Comment"] AuditTable [1] = ["11/23/2009 8:52:18 AM","missing","OK","user comment number 1","1/1/2009","ok","audit comment number 1"] AuditTable [2] = ["11/24/2009 12:21:19 AM","missing","Out of Date","Changes from 2008 not implemented","1/2/2009","Out of Date","needs update"] AuditTable [3] = ["11/22/2009 9:24:42 PM","missing","Incomplete","Document doesnt cover all possibilities","1/3/2009","Inadequate","needs update"] I have hard coded values and had success such as: Code: data = AuditTable[1][0] But when I put the vars associated with the loop in I get an undefined error - AuditTable[i] is undefined: Code: // produces error data = AuditTable[i][j] //Works but retrieves wrong data data = AuditTable[j][i] //Works but retrieves wrong data data = AuditTable[1][i] //Works but retrieves wrong data data = AuditTable[j][2] I must be trying to access the array incorrectly or something... I have defined all the vars, and tried many combinations, alerted the values of both vars so I can prove it is not a scope issue... Am I missing something obvious? Thanks much... Code: var reportArray=new Array();
var reportData, title, subTitle, data;

{
title = '<div style="font-family:verdana; font-size:14px; font-weight:bold; margin:25px 0px 5px 30px">';
title += namearray[i][0];
title += '</div>';
reportArray.push(title);//Take compiled variable value and put it into array
for(j=0; j < AuditTable[0].length; j++)// loop thru AuditTable array and get values
{
subTitle = AuditTable[0][j];//points to first row of AuditTable where the labels are
data = AuditTable[1][0];//points to the current row where actual data is

Hi Guys, Quick question, is there a way to stop a JavaScript from validating after a certain point of the code. I've been "googling" like crazy and cant find a solution. I had to add a Checkbox validation last second and there was existing validation and I'm not good enough to alter all of it to reflect the checkbox part so what I did was I checked to see if at least one of the checkboxes was selected, if yes, do nothing and finish the rest of the validation. If no, prompt them with an error. The problem is after it prompts them for an error, it continues to run the rest of the validation and at the end it allows the end user to print. I cannot allow the end user to print until everything is filled in. Here is my code: Code: function validateFields() {
var fieldsToVerify = [
["PrincipalInvestigator"],
["ContactEmailAddress"],
["RFAward"],
["Sponsor"],
["AwardTitle"],
["BudgetStartDate"],
["BudgetEndDate"],
["SectionII"],
["ProjectRole"],
["EmployeeName"],
["DatesofAppointment"],
["EffortonProject"],
["Date"],
["PrintName"],
["Date2"],
["PrintName2"],
];
var emptyFields = [];
var notFullFields = [];
for (var i=0; i<fieldsToVerify.length; i++) {
var f = this.getField(fieldsToVerify[i][0]);
if (f==null) {
console.println(fieldsToVerify[i][0] + " not found.");
continue;
}
if (f.valueAsString=="") {
emptyFields.push(f.name);
} else if (fieldsToVerify[i].length>1 && f.valueAsString.length<fieldsToVerify[i][1]) {
notFullFields.push([f.name,fieldsToVerify[i][1]]);
}
}
for (var i in nonRequiredFieldsToVerify) {
var f = this.getField(nonRequiredFieldsToVerify[i]);
if (f==null) {
console.println(nonRequiredFieldsToVerify[i] + " not found.");
continue;
}
if (f.valueAsString!="" && f.valueAsString.length<f.charLimit) {
notFullFields.push([f.name,f.charLimit]);
}
}
if
(this.getField("CheckBox1").value=="Yes" || this.getField("CheckBox2").value=="Yes" || this.getField("CheckBox3").value=="Yes" || this.getField("CheckBox4").value=="Yes" || this.getField("CheckBox5").value=="Yes" || this.getField("CheckBox6").value=="Yes" || this.getField("CheckBox7").value=="Yes")
{}
else
app.alert("Select a Checkbox in Section I before printing")
if (emptyFields.length==0 && notFullFields.length==0) {
this.print();
} else {
var msg = "";
if (emptyFields.length>0) {
msg += "The following fields must be filled-in:\n";
for (var i in emptyFields)
msg += emptyFields[i]+"\n";
}
if (notFullFields.length>0) {
if (msg!="") msg+="\n\n";
msg += "The following fields are not filled-in completely:\n";
for (var i in notFullFields)
msg += notFullFields[i][0] + " (required length: " + notFullFields[i][1] + ")\n";
}
app.alert(msg,"");
}

Hello, I found the javascript for triggering audio on mouseOver (on the page link below) very helpful. Question is - how to stop the audio on mouseout? http://www.javascriptkit.com/script/....shtml#current Is there anyway to stop the page 'jumping to the top' when using a link like the below? Code: <a href="#" onClick="arrangeCards();">blah</a> .. I just want it to stay in the same position on the page & not jump to the top of the page every time a link like that is clicked. Cheers! Been given a task to edit a simple javascript slide show to have form buttons This what i have so far.. I have the next and back buttons working but i have no idea where to begin with play and stop.

My code to call the js document in the file 'boot.js'. Code: var o = 'http://www.example.com/file.js';
document.write("<script src=\""+o+"\" type=\"text\/javascript\"><\/scr"+"ipt>");
And in index.html I have this script tag Code: <script type="text/javascript" src="http://www.example.com/boot.js"></script> Hey CodingFourm-ites! Ive scoured the internet for scripts that make a <div> follow the mouse, and have found one that seems to work well. However, I want the <div> to stop moving when the CTRL or the SHIFT key is pressed, I dont care which. Hopefully, I can have a div that follows the mouse at an offset that contains some click-able items, so a menu is always by your mouse. Ive tried now more than a few times to put together a piece of code that can achieve this, but none have worked. Can somebody write a script that can achieve this, or point me in the right direction? Thanks guys! Current JS for mouse follow: Code: var divName = 'mouseFollow'; // div that is to follow the mouse
// (must be position:absolute)
var offX = 15; // X offset from mouse position
var offY = 15; // Y offset from mouse position
function mouseX(evt) {if (!evt) evt = window.event; if (evt.pageX) return evt.pageX; else if (evt.clientX)return evt.clientX + (document.documentElement.scrollLeft ? document.documentElement.scrollLeft : document.body.scrollLeft); else return 0;}
function mouseY(evt) {if (!evt) evt = window.event; if (evt.pageY) return evt.pageY; else if (evt.clientY)return evt.clientY + (document.documentElement.scrollTop ? document.documentElement.scrollTop : document.body.scrollTop); else return 0;}
function follow(evt) {if (document.getElementById) {var obj = document.getElementById(divName).style; obj.visibility = 'visible';
obj.left = (parseInt(mouseX(evt))+offX) + 'px';
obj.top = (parseInt(mouseY(evt))+offY) + 'px';}}
document.onmousemove = follow;
The original code can be found at: http://javascript.about.com/library/blfollow2.htm I am very new to Javascript - as in this is the first day I'm using it. I am using a code I got offline to fade three pictures together, but when it gets to the last image, it loops back to the first. How do I code it so that when it gets to the last image, it stops? Here is the code - sorry if its messy. Javascript: /***** Image Cross Fade Redux Version 1.0 Last revision: 02.15.2006 steve@slayeroffice.com Please leave this notice intact.

Thanks to Old Pedant , in this forum, I am using this basic code for a slideshow he posted: Code: var slides = [
[ "abc.jpg", 3000 ],
[ "xyz.png", 5000 ],
[ "foo.gif", 1500 ]
];
var curSlide = 0;
function nextSlide( )
{
document.getElementById("thePicture").src = slides[curSlide][0].src;
setTimeout( nextSlide, slides[curSlide][1] );
curSlide = ( curSlide + 1 ) % slides.length;
}
function setUp( )
{
for ( var s = 0; s < slides.length; ++s )
{
var image = new Image();
image.src = slides[s];
slides[s] = image;
}
nextSlide( );
}
window.onload = setUp;
which works just fine. But I can't find a way for it to play one round of the slides then stop. Could someone please help me with the right bit of code to stop the show? I know the code is a bit basic (no fades etc) but I have been unable to find a similar slideshow product that gives variable time delays for each slide. I've googled endlessly but nothing could i find.... TIA Richard ========= Hi all. I have this simple javascript that initiates a flash player. Code: <script type="text/javascript">
function add_content(filedesc,filepath,whatarget)
{
var output = "" + filedesc + "</b><br />";
output += "<object type='application/x-shockwave-flash' data='mp3player.swf'>";
output += "<param name='movie' value='mp3player.swf'>";
output += "<param name='wmode' value='transparent'>";
output += "<param name='FlashVars' value='mp3=" + filepath + ">";
output += "</object></div>";
output += "" + whatarget + "";
document.getElementById("" + whatarget + "").innerHTML = output;
}
</script>
and this takes care of the onclick event: Code: <a href="javascript:void;" onclick="javascript:add_content('Hello1','../m_music/omd.mp3','target1');">Omd</a><div id='target1'></div>
<a href="javascript:void;" onclick="javascript:add_content('Hello2','../m_music/blondie.mp3','target2');">blondie</a> <div id='target2'></div>
page and vars are going to be dynamic. My question is: if I press 'target1' it plays. When I press 'target2' second player plays in its div layer. How can I start one player while stopping another (I am guessing 'target1' must be hidden). I am going to have many mp3 files and I want each player to be in its rightful place. I've looked for functions, but I am not that experienced with JV syntax. Thank you. |
