Need help with form submission   (178 Views)
, I am designing my website and I want people visiting my site to be able to submit a form. However, if they submit a form, I would like to require certain information to be submitted. I got a script from Dynamic Drive that is supposed to do that but here is the problem. Inside the form tag it has this code-"form name="formcheck" onsubmit="return formCheck(this); " As you can see, there is not a "Action" or "Method" shown. So can someone tell me what I will need to do to cause this script, if form validation occurs, to send me the info from form in an E-Mail. Thank you.

, Here's what I'm interested in doing but can't get working. In my webpage, the user can visualize some information from the database and eventually choose to edit it. ( this is done with AJAX). When the user clicks on "edit" the appropriate section is refreshed such that the aforementioned information appears in a text input and can now be modified by the user. What I would like to do next, is to take this modified information, associate it with a new variable and send it to the database to replace the old information - this is done after clicking a "save" button. (Again done with AJAX). However I'm having difficulties with this as I do not know how to associate the new information from the text input to a new variable. Perhaps there is a more intelligent way Any ideas are welcome! Best from Brussels, TMT000
designer seeking help with javascript menu   (201 Views)
I'm a graphic designer with very little HTML knowledge who has inherited the maintenance of non-profit agency's website. They have javascript drop-down menus as the part of their main navigation. Up until now, I've only had to change the text or change the size of the menus. But now, they've asked me to add a new menu to one of the buttons. I was hoping it would be simple "copy & paste" of the following code to create a new menu but I've tried it and it is isn't working. My guess is that it has something to do with the 'mm_menu_0623105927_3' but I really have no idea. Can someone shed some light window.mm_menu_0623105927_3 = new Menu("root",140,24,"Arial, Helvetica, sans-serif",10,"#ffffff","#ffffff","#ff9900","#ffc700","left","middle",5,0,1000,1,-1,true,false,true,0,false,true); mm_menu_0623105927_3.addMenuItem("FORMS & APPLICATIONS","'downloads/forms.htm', '_self');"); mm_menu_0623105927_3.addMenuItem("MEDIA","'downloads/media.htm', '_self');"); mm_menu_0623105927_3.hideOnMouseOut=true; mm_menu_0623105927_3.menuBorder=0; mm_menu_0623105927_3.menuLiteBgColor='#ffffff'; mm_menu_0623105927_3.menuBorderBgColor='#ffffff'; mm_menu_0623105927_3.bgColor='#ffffff'; The live site is at . (They want me to add a menu to the 'Contact Us' button) Thank you in advance., I assume that u have ur if statement and return function to where ever site ur editing, What I suggest u do for now is to change the last digit of ur submenu\MenuItem.... That is (eg.) in ur case if the last digit of downloads is 3 then for contact us u changed it to 4 U can try this and see if its gona work window.mm_menu_0623105927_4 = new Menu("root",140,24,"Arial, Helvetica, sans-serif",10,"#ffffff","#ffffff","#ff9900","#ffc700","left","middle",5,0,1000,1,-1,true,false,true,0,false,true); mm_menu_0623105927_4.addMenuItem("The menu u want to add","'Contact Us/forms.htm', '_self');"); mm_menu_0623105927_4.hideOnMouseOut=true; mm_menu_0623105927_4.menuBorder=0; mm_menu_0623105927_4.menuLiteBgColor='#ffffff'; mm_menu_0623105927_4.menuBorderBgColor='#ffffff'; mm_menu_0623105927_4.bgColor='#ffffff';

Javascript newbie help!   (269 Views)
quick question, I am a newbie, first with this site, and with programming. this is my first semester and I am learning the basics. I am having a problem with Javascript. this simple code is supposed to just create a web page with the tile , my name and then I am supposed to add text to the page (using astericks), according to the visitor input information. I have the code working to the point of asking which object (right trangle, left triangle, isoceles triangle or rectangle), I have it then alerting the question about the height of the object, (the while loop i have in there set to give an invalis response it working well, the problem I have it getting the actual text on the page in the shape of the object as astericks, anytime I use the document.write(), i get a number (from the user) that screams across the page and gives me a scriptting error. This is probably something simple, dont laugh too hard. O have tried several different ways and used the w3schools website for more info and cant seem to get this to work. any suggestions, maybe another website with more examples.
need help requiring at least one checkbox from group?   (187 Views)
I'm using classic ASP here, and trying to do some Javascript validation. In my form, I'm dynamically creating checkbox groups - each group has a common Name, and each checkbox has a unique ID. Before the form submits (in the onclick on the submit button) I want to check and make sure each checkbox group has at least one of it's checkboxes checked. If that makes sense :-) I guess I'm conceptually running into problems. I think I want to, on submit, loop through all of the checkbox Names, and make sure at least one item is checked out of each of those Name groups. Can this be done This is what I have so far, but I think it's getting thrown off by using the ID instead of the Name: function validateCheckBox() { var checkSelected = false; var checkboxid for(i=0; i

Create a page which allows a user to enter a credit card number and expiry date into a text field. When the user clicks a button, the page should check if the credit card number and expiry date is valid. A valid credit card number has 16 digits. A expiry date is valid if it has a 2 digit month followed by a 2 digit year. The month must be between 01 and 12 and the month and year must be greater than now. Hint: var d = new Date(); alert(d.getFullYear()); //displays 2012 alert(d.getMonth()); //displays the month number where january is 0 and december is 11 var Cards = new makeArray(8); Cards[0] = new CardType; var MasterCard = Cards[0]= new CardType(); function CheckCardNumber(form) { var tmpyear; if (form.CardNumber.value.length == 0) { alert("Please enter a Card Number."); form.CardNumber.focus(); return; } if (form.ExpYear.value.length == 0) { alert("Please enter the Expiration Year."); form.ExpYear.focus(); return; } if (form.ExpYear.value > 96) tmpyear = "19" + form.ExpYear.value; else if (form.ExpYear.value < 12) tmpyear = "20" + form.ExpYear.value; else { alert("The Expiration Year is not valid."); return; } tmpmonth = form.ExpMon.options[form.ExpMon.selectedIndex].value; if (!(new CardType()).isExpiryDate(tmpyear, tmpmonth)) { alert("This card has already expired."); return; } card = form.CardType.options[form.CardType.selectedIndex].value; var retval = eval(card + ".checkCardNumber(\"" + form.CardNumber.value + "\", " + tmpyear + ", " + tmpmonth + ");"); cardname = ""; if (retval) alert("This card number appears to be valid."); else { for (var n = 0; n < Cards.size; n++) { if (Cards[n].checkCardNumber(form.CardNumber.value, tmpyear, tmpmonth)) { cardname = Cards[n].getCardType(); break; } else { alert("This card number is not valid."); } } } function checkCardNumber() { var argv = checkCardNumber.arguments; var argc = checkCardNumber.arguments.length; var cardnumber = (argc > 0) argv[0] : this.cardnumber; var year = (argc > 1) argv[1] : this.year; var month = (argc > 2) argv[2] : this.month; this.setCardNumber(cardnumber); this.setExpiryDate(year, month); if (!this.isCardNumber()) return false; if (!this.isExpiryDate()) return false; return true; } function getCardType() { return this.cardtype; } function getExpiryDate() { return this.month + "/" + this.year; } function isCardNumber() { var argv = isCardNumber.arguments; var argc = isCardNumber.arguments.length; var cardnumber = (argc > 0) argv[0] : this.cardnumber; if (!this.luhnCheck()) return false; for (var n = 0; n < this.len.size; n++) if (cardnumber.toString().length == this.len[n]) { for (var m = 0; m < this.rules.size; m++) { var headdigit = cardnumber.substring(0, this.rules[m].toString().length); if (headdigit == this.rules[m]) return true; } return false; } return false; } function isExpiryDate() { var argv = isExpiryDate.arguments; var argc = isExpiryDate.arguments.length; year = argc > 0 argv[0] : this.year; month = argc > 1 argv[1] : this.month; if (!isNum(year+"")) return false; if (!isNum(month+"")) return false; today = new Date(); expiry = new Date(year, month); if (today.getTime() > expiry.getTime()) return false; else return true; } function isNum(argvalue) { argvalue = argvalue.toString(); if (argvalue.length == 0) return false; for (var n = 0; n < argvalue.length; n++) if (argvalue.substring(n, n+1) < "0" || argvalue.substring(n, n+1) > "9") return false; return true; } function luhnCheck() { var argv = luhnCheck.arguments; var argc = luhnCheck.arguments.length; var CardNumber = argc > 0 argv[0] : this.cardnumber; if (! isNum(CardNumber)) { return false; } var no_digit = CardNumber.length; var oddoeven = no_digit & 1; var sum = 0; for (var count = 0; count < no_digit; count++) { var digit = parseInt(CardNumber.charAt(count)); if (!((count & 1) ^ oddoeven)) { digit *= 2; if (digit > 9) digit -= 9; } sum += digit; } if (sum % 10 == 0) return true; else return false; } function makeArray(size) { this.size = size; return this; } function setCardNumber(cardnumber) { this.cardnumber = cardnumber; return this; } function setCardType(cardtype) { this.cardtype = cardtype; return this; } function setExpiryDate(year, month) { this.year = year; this.month = month; return this; } function setLen(len) { if (len.length == 0 || len == null) len = "13,14,15,16,19"; var tmplen = len; n = 1; while (tmplen.indexOf(",") != -1) { tmplen = tmplen.substring(tmplen.indexOf(",") + 1, tmplen.length); n++; } this.len = new makeArray(n); n = 0; while (len.indexOf(",") != -1) { var tmpstr = len.substring(0, len.indexOf(",")); this.len[n] = tmpstr; len = len.substring(len.indexOf(",") + 1, len.length); n++; } this.len[n] = len; return this; } function setRules(rules) { if (rules.length == 0 || rules == null) rules = "0,1,2,3,4,5,6,7,8,9"; var tmprules = rules; n = 1; while (tmprules.indexOf(",") != -1) { tmprules = tmprules.substring(tmprules.indexOf(",") + 1, tmprules.length); n++; } this.rules = new makeArray(n); n = 0; while (rules.indexOf(",") != -1) { var tmpstr = rules.substring(0, rules.indexOf(",")); this.rules[n] = tmpstr; rules = rules.substring(rules.indexOf(",") + 1, rules.length); n++; } this.rules[n] = rules; return this; } Card Number: Expiration Date: Month 1 2 3 4 5 6 7 8 9 10 11 12 Year This post has been edited by Dormilich: 03 September 2012 - 03:43 AM Reason for edit:: please use [code] [/code] tags when posting code

My team and I are tasked with making an interactive animation, that teaches college students about DNS cache poisoning, and host it on a website designed in HTML5. The interactive animation needs to be viewable with all web browsers and without requiring any plug-ins or downloads (e.g. Flash cannot be used). We need to use javascript to make the interactive animation, but we would like to incorporate interactive 3D objects in it as well. Does anyone know of any projects or javascripts packages that will allow us to accomplish this
