Working on college assignment, cant figure it out and need help! Basically a form that asks the user to fill in a valid email and password (ill give them the password), doesnt matter if it isnt secure, or if the email accepts dodgy emails (im just verifying the @ and a . and that is ok for the purpose of this. Anyway been trying with this code for ages now and cant see what is wrong but it isnt working, ive swapped it around and at times it does check that it is a valid email, sometimes it allows empty inputs. here is the code <script type="text/javascript"> function validateForm() { var x=document.forms["myForm"]["email"].value var y=document.forms["myForm"]["password"].value var atpos=x.indexOf("@"); var dotpos=x.lastIndexOf("."); if (atpos<1 || dotpos<atpos+2 || dotpos+2>=x.length) { alert("Not a valid e-mail address"); return false; } </script> I think i need something like && (y!="123") around the 'if' statement, but not a clue how or where it goes. Basically im going to set the password to 123 so dont have to allow for caps etc. Easiest way to do this, anyone plleeeeeaaasseee??

I'm attempting to use the jQuery iviewer to control the viewing of images. I'm essentially making my own slideshow. In any event, I'm trying to tag a map along with the image. The only way I know of doing this is with standard markup doing usemap="#map_name". so here's my JavaScript code, and the HTML to follow. Code: var $ = jQuery; $(document).ready(function(){ $("#viewer").iviewer( { src: "images/page11.jpg", update_on_resize: false, initCallback: function () { var object = this; $("#in").click(function(){ object.zoom_by(1);}); $("#out").click(function(){ object.zoom_by(-1);}); $("#fit").click(function(){ object.fit();}); $("#orig").click(function(){ object.set_zoom(100); }); $("#update").click(function(){ object.update_container_info();}); }, onMouseMove: function(object, coords) { }, onStartDrag: function(object, coords) { return false; }, onDrag: function(object, coords) { } }); $("#viewer2").iviewer( { src: "images/page11.jpg", update_on_resize:false, initCallBack: function () { document.images[0].useMap = "#map1"; } }); }); And the 'scaler' Code: function scalecoordimages(elImage, amount){ var elMap = getMap(elImage) elImage.width *= amount; elImage.height *= amount; if (null != elMap){ for (var intLoop = 0; intLoop < elMap.areas.length; intLoop++) { var elArea = elMap.areas[intLoop]; var coords = elArea.coords.split(","); var scaledCoords = ""; for (coords in coords) { scaledCoords += (coords[coord] * amount) + ","; } elArea.coords = scaledCoords; } } } and now the HTML where this is all delivered. Code: <div class="wrapper"> <div id="viewer2" class="viewer" style="margin: 50px auto;"></div> </div> the 'wrapper' is because in Safari the overflow doesn't hold properly and breaks. the Map is just rectangles...it's below > Code: <map name="map1" id="map1"> <area class="hotspot" shape="rect" coords="105, 1110, 371, 1125" href="" onMouseOver="tooltip.show('<ul>Northeast States:<br /><li>Connecticut</li><li>Maine</li> <li>Massachusetts</li><li>New Hampshire</li><li>Rhode Island</li><li>Vermont</li><li>New Jersey</li><li>New York</li><li>Pennsylvania</li></ul>');" onMouseOut="tooltip.hide();" > <area class="hotspot" shape="rect" coords="105, 1135, 371, 1150" href="" onMouseOver="tooltip.show('<ul>Midwest States:<br /><li>Indiana</li><li>Illinois</li><li>Michigan</li><li>Ohio</li><li>Wisconsin</li><li>Iowa</li><li>Kansas</li><li>Minnesota</li><li>Missouri</li><li>Nebraska</li><li>North Dakota</li><li>South Dakota</li></ul>');" onMouseOut="tooltip.hide();"></area> <area class="hotspot" shape="rect" coords="105, 1160, 371, 1175" href="" onMouseOver="tooltip.show('<ul>Southern States:<br /><li>Delaware</li><li>Florida</li><li>Georgia</li><li>Maryland</li><li>North Carolina</li><li>South Carolina</li><li>Virginia</li><li>West Virginia</li><li>Alabama</li><li>Kentucky</li><li>Mississippi</li><li>Tennessee</li><li>Arkansas</li><li>Louisiana</li><li>Oklahoma</li><li>Texas</li></ul>');" onMouseOut="tooltip.hide();"></area> <area class="hotspot" shape="rect" coords="105, 1185, 371, 1200" href="" onMouseOver="tooltip.show('<ul>Western States:<br /><li>Arizona</li><li>Colorado</li><li>Idaho</li><li>New Mexico</li><li>Montana</li><li>Utah</li><li>Nevada</li><li>Wyoming</li><li>Alaska</li><li>Californai</li><li>Hawaii</li><li>Oregon</li><li>Washington</li></ul>')" onMouseOut="tooltip.hide();"></area> </map> Any help is appreciated.

Thanks you. Clement Osei. Hello I'd really appreciate some help please, no other forum seems to have an answer for this. Example : I have a file called values.asp and in that file are 100 different variables all assigned a specific number. I also have a results.asp file or a simple html page. The target is to read a specific variable in the values.asp file and then display it in another asp file or standard HTML file using Javascript's document.write(variablename); method. So in other words, i wish to fetch a specific variables value from values.asp and show it in another asp file or a simple html file using javascript. Your help will be very much appreciated. Thanks! Ron I'm getting 'XMLSerializer is undefined' when I used the below code snippet in Java script. var xmlDoc=xmlhttp.responseXML; var Xml2String=xmlhttp.responseXML.xml; if (xmlDoc.xml) { Xml2String=xmlDoc.xml; }else{ Xml2String= new XMLSerializer().serializeToString(xmlDoc); } Please help me to solve this problem? Thanks in advance. airwindjai. I am not super familiar with code - I can easily take code and with a little direction get the desired end result so anyone who can help me with this it will be VERY appreciated. I don't even know what terms to search in order to create a page that I am looking for.... So here goes: I want to model our distributor page after a R E D K E N.com Distributor Locator Page. Here is what happens.... There is a drop down menu of the 50 states, and when you select the state the table of information below changes. screen shots below I am sure this is fairly easy to resolve, however I don't know where to begin. Thank You in advance for your time. Kristi Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title> Jackhammer </title> <meta http-equiv="content-type" content="text/html; charset=iso-8859-1" /> <script type="text/javascript"> /* <![CDATA[ */ var jackhammers = new Array(11); var curJackhammer = 0; var direction; var begin; jackhammers[0] = "jackhammer0.gif"; jackhammers[1] = "jackhammer1.gif"; jackhammers[2] = "jackhammer2.gif"; jackhammers[3] = "jackhammer3.gif"; jackhammers[4] = "jackhammer4.gif"; jackhammers[5] = "jackhammer5.gif"; jackhammers[6] = "jackhammer6.gif"; jackhammers[7] = "jackhammer7.gif"; jackhammers[8] = "jackhammer8.gif"; jackhammers[9] = "jackhammer9.gif"; jackhammers[10] = "jackhammer10.gif"; function bounce() { if(curJackhammer == 10) curJackhammer = 0; else ++curJackhammer; /* Firefox does not register an error with the line of code below, but other browsers do . . . It looks like it is a typo left over from the slightly more advanced technique in 10-4 where jackhammers.src is defined. Also, were you to comment out the final line in this function you would see the animation does not work. In browsers other than Firefox which apparently just ignores this code and no animation occurs, the image element is assigned the source value of "undefined" and of course no image is named "undefined". */ document.getElementsByTagName('img')[0].src = jackhammers[curJackhammer].src; if(curJackhammer == 0) direction = "up"; else if(curJackhammer == 10) direction = "down"; document.getElementsByTagName('img')[0].src = jackhammers[curJackhammer]; } function startBouncing() { if(begin) clearInterval(begin); begin = setInterval("bounce()",90); } /* ]]> */ </script> </head> <body> <h1> Jackhammer Man </h1> <p> <img src="jackhammer0.gif" height="113" width="100" alt="Image of a man with a jackhammer." /> </p> <form action="" enctype="text/plain"> <p> <input type="button" value="Start Bouncing" onclick="startBouncing();" /> <input type="button" value="Stop Bouncing" onclick="clearInterval(begin);" /> </p> </form> </body> </html> My teacher insists that the above code is valid (straight out of our book). He says this because (I'm guessing) it runs okay in Firefox and other browsers. It also throws a ton of error messages in Chrome and makes no logical sense. We define the values of the jackhammer array as literal strings, and then the book instructs us to change the source of the image element on the page to jackhammers[i].src. It then has us change the source of the image element again, correctly at the end of the function. It also has us create a useless variable: "direction" (and I say useless because we never use it, it is just fluff I guess). On a side note, would some of you guys like to check out this animation I created here and let me know what you think. Thanks guys. the title kind of sums it up... if I have an array of equations (I'm guessing they should be strings but they don't have to be) and a user-defined variable can that variable be used for the "x" in the equations? I already did the easy part ... Code: <!DOCTYPE html> <html> <head> </head> <body> <input onkeyup="solve(this.value)" /><br> <input id="box0" /><br> <input id="box1" /><br> <input id="box2" /><br> <script type="text/javascript"> var equations=["(x*9/5)+32","x+273.15","x-50*(8/13)"] function solve(val){ for (var i = 0; i < equations.length; i++) { document.getElementById("box"+i).value= //ummm... } } </script> </body> </html> First post on the forum... I'm brand new to Javascript and I'm teaching myself using the Headfirst HTML5 book. One of the exercises early in the book is asking me to create a musical playlist where I can add songs that will show up on the screen and also be added to the DOM. However, I'm not able to get it to work or see where my error lies. Any feed back would be great. Here's my code: Code: <!doctype html> <html lang="en"> <head> <title>Webville Tunes</title> <meta charset = "utf-8"> <script> function init() { var button = document.getElementById("addButton"); button.onclick = handleButtonClick; window.onload = init; } function handleButtonClick() { var textInput = document.getElementById("songTextInput"); var songName = textInput.value; var li = document.createElement("li"); li.innerHTML= songName; var ul = document.getElementById("playlist"); ul.appendChild(li); alert ("Button was clicked!"); } </script> <link rel = "stylesheet" href="playlist.css"> </head> <body> <form> <input type="text" id="songTextInput" size="40" placeholder="Song name"> <input type="button" id="addButton" value="Add Song"> </form> <ul id="playlist"> </ul> </body> </html> Can't seem to delete.

Hi, can anyone help me with a simple bit of javascript? I need to modify the following code for a date of birth selector to return false if they date of birth is less than 18 years old. jQuery.validator.addMethod("validDOB", function (str1, element) { var mon1 = parseInt(str1.substring(0,2),10); var dt1 = parseInt(str1.substring(3,5),10); var yr1 = parseInt(str1.substring(6,10),10); var date1 = new Date(parseInt(yr1), parseInt(mon1)-1, parseInt(dt1)); var date2 = new Date(); if(date2 < date1) { return false; } else { return true; } }, "Please enter valid date of birth"); thanks baronne Hi all, this is my first attempt at JavaScript code. I'm trying to write code for an Adobe Acrobat form. Here is my situation: I have several boxes, all containing numbers such as 2014, 08, and 000000000. I want to concatenate them all into one long number like 080000000002014. I've looked at a ton of sample code, but nothing I try seems to work. Any help is greatly appreciated.
