Create the container for the scroller in the body of your HTML:** <div id="scr1"></div>** Where "scr1" is any name you choose. You don't have to use a <div>* either. You may use any block level element that can be pixel* resized; such as a <span> element to which the display:block; CSS* property has been applied.************************************************************************* 2. Fill the scroller container with child <div> blocks:** <div id="scr1">* <div class="default">* The contents of this block will be displayed if the browser does* not support the scroller.* It will be overwritten if the scroller is supported.* </div>* <div>Block 2</div>* <div>Block 3</div>** ...** </div>** Assign the class "default" to the first block, the one which you* would like displayed if javascript is disabled.************************************************************************* 3. Add the following rule(s) to your CSS stylesheet:** #scr1 div {* visibility:hidden;* }* #scr1, #scr1 div.default {* width:160px;* height:120px;* overflow:hidden;* visibility:visible;* }* #scr1 table tr td div {* visibility:visible;* }** Change both "scr1" to the id you gave to the scroller container. The* width and height properties should match those you will use in step 4.** To further style the scroller container, assign CSS properties to the* scroller target id:** #scr1 {* background-color:#f6f6f6;* margin:0px auto;* }** The script will replace each block you add to the container with a* single-celled <table>. So to style the blocks of your scroller, you* can style these table cells as if they were actually part of your* document source:** #scr1 table tr td {* padding:10px;* color:#ff0000;* text-align:center;* vertical-align:middle;* }************************************************************************* 4. Create a new scrollObject:** new scrollObject("scr1", 120, 120, "up", 5000, 1.4);** The arguments for this object are as follows:* a. - ID of the target tag (from step 1)* b. - Width (in pixels) of your scroller* c. - Height (in pixels) of your scroller* d. - Scroll direction: one of "up", "down", "left" or "right"* e. - Amount of time to pause before next scroll begins (ms)* f. - Slide-in speed of your scroller (1.001 up to width or height)*************************************************************************** To add more scrollers to the same page: *************************************************************************************************** 1. Create additional containers - with different ID's - and blocks in* the body of your HTML** <div id="scr2">* <div class="default"><strong>HTML is allowed too!</strong></div>* <div><img src="/images/mybanner.jpg" alt=""></div>* <div><a href="/home">And links!</a></div>* <div>As long as it fits within the dimensions above</div>* </div>** <div id="scr3">* <div class="default">Block 1</div>* <div>Block 2</div>* <div>Block 3</div>* <div>Block 4</div>* </div>************************************************************************* 2. Add the matching rules to your CSS stylesheet** #scr2 div,* #scr3 div {* visibility:hidden;* }* #scr2, #scr2 div.default {* width:468px;* height:60px;* overflow:hidden;* visibility:visible;* }* #scr3, #scr3 div.default {* width:140px;* height:140px;* overflow:hidden;* visibility:visible;* }* #scr2 table tr td div,* #scr3 table tr td div {* visibility:visible;* }************************************************************************* 3. Create new scrollObjects for each scroller in the <script> tag:** new scrollObject("scr2", 468, 60, "down", 10000, 1.2);* new scrollObject("scr3", 140, 140, "right", 4000, 2);*************************************************************************** End Instructions ***************************************************************************************************** BEGIN CODE ***** *//* ***** * See http://www.greywyvern.com/code/js/scroller.html for the page * which uses the example scrollers below * */// ***** Start scroller #1new scrollObject("scr1", 160, 120, "up", 5000, 1.15);// ***** Start scroller #2new scrollObject("scr2", 468, 60, "left", 3000, 1.5);/* ******************************************************************** * The Mighty ScrollObject * - Don't edit this if you know what's good for ya! * */function scrollObject(main, width, height, direct, pause, speed) { var self = this; this.main = main; this.width = width; this.height = height; this.direct = direct; this.pause = pause; this.speed = Math.max(1.001, Math.min((direct == "up" || direct == "down") ? height : width, speed)); this.slope = (direct == "up" || direct == "left") ? 1 : -1; this.prev = this.offset = 0; this.curr = 1; this.mouse = false; this.scroll = function() { this.main = document.getElementById(this.main); this.main.style.overflow = "hidden"; this.main.style.position = "relative"; this.main.style.width = this.width + "px"; this.main.style.height = this.height + "px"; var b = [], c; while (this.main.firstChild) if ((c = this.main.removeChild(this.main.firstChild)).nodeName == "DIV") b.push(c); for (var x = 0; x < b.length; x++) { var table = document.createElement('table'); table.cellPadding = table.cellSpacing = table.border = "0"; table.style.position = "absolute"; table.style.left = table.style.top = "0px"; table.style.width = table.style.height = "100%"; table.style.overflow = table.style.visibility = "hidden"; var tbody = document.createElement('tbody'); var tr = document.createElement('tr'); var td = document.createElement('td'); while (b[x].firstChild) td.appendChild(b[x].removeChild(b[x].firstChild)); tr.appendChild(td); tbody.appendChild(tr); table.appendChild(tbody); this.main.appendChild(table); } b = c = null; if (this.main.childNodes.length > 1) { this.main.onmouseover = function() { self.mouse = true; }; this.main.onmouseout = function() { self.mouse = false; }; setInterval(function() { if (!self.offset && self.scrollLoop()) self.main.childNodes[self.curr].style.visibility = "visible"; }, this.pause); } this.main.childNodes[this.prev].style.visibility = "visible"; }; this.scrollLoop = function() { if (!this.offset) { if (this.mouse) return false; this.offset = (this.direct == "up" || this.direct == "down") ? this.height : this.width; } else this.offset = Math.floor(this.offset / this.speed); if (this.direct == "up" || this.direct == "down") { this.main.childNodes[this.curr].style.top = (this.offset * this.slope) + "px"; this.main.childNodes[this.prev].style.top = ((this.offset - this.height) * this.slope) + "px"; } else { this.main.childNodes[this.curr].style.left = (this.offset * this.slope) + "px"; this.main.childNodes[this.prev].style.left = ((this.offset - this.width) * this.slope) + "px"; } if (!this.offset) { this.main.childNodes[this.prev].style.visibility = "hidden"; this.prev = this.curr; if (++this.curr >= this.main.childNodes.length) this.curr = 0; } else setTimeout(function() { self.scrollLoop(); }, 30); return true; }; if (window.addEventListener) { window.addEventListener('load', function() { self.scroll(); }, false); } else if (window.attachEvent) window.attachEvent('onload', function() { self.scroll(); });}</script><div id="scr1"><div class="default"><i>The JavaScript Bank</i> is an excellent JavaScript resource.</div><div><b>Want some recognition for your scripts?</b><br><a href="http://javascriptbank.com/submit/">Submit them to us</a> and they can be featured on JavaScript Source!</div><div>Three times a week we add a new script or tutorial to our archives.</div></div>
