JavaScript - Detecting Non English Characters
My credit card processing service will only accept English characters. I need to detect entries in the form that are using non English characters.
Is there a way in Javascript to create a function to force a string to UTF-8? My idea is to do something like function forceUTF8(X){ Y = ???? X; return Y; } if ( stringA != forceUTF8(stringA) alert ("You must use English Characters"); Similar TutorialsHere is an XML file (See Below) and a TEXTBOX. How can I use them to transliterate fom English To Kannada using JAVASCRIPT? Whenever I type in English it must appear in Kannada in the Textbox. What is the Jascript Code to acieve the result? /* Sample.xml */ <?xml version="1.0" ?> <Catalog> <Mappings> <Vowels> <!-- Vowels --> <om>a ಅ</om> <om>aa ಆ</om> <om>A ಆ</om> <om>i ಇ</om> <om>ee ಈ</om> <om>ii ಈ</om> <om>I ಈ</om> <om>u ಉ</om> <om>oo ಊ</om> <om>uu ಊ</om> <om>U ಊ</om> <om>rux ಋ</om> <om>Rux ೠ</om> <om>e ಎ</om> <om>ae ಏ</om> <om>E ಏ</om> <om>ai ಐ</om> <om>o ಒ</om> <om>oa ಓ</om> <om>O ಓ</om> <om>au ಔ</om> <om>ou ಔ</om> <om>ow ಔ</om> <om>aM ಅಂ</om> <om>amx ಅಂ</om> <om>aH ಅಃ</om> </Vowels> </Mappings> </Catalog> So I have an assignment where I need to make a program to make a simple translator. Where I insert a text box for the user to input i.e. "Hello" and the other textbox to display the word in spanish. Problem is im having trouble displaying the output and having a textbox to out put it too. Also i dont think my button is functioning correctly. Please help! It would be greatly appreciated! <html> <h2> English to Spanish Translator </h2> <head> <script type = "text/javascript"> PHRASES = [["hello", "hola"], ["hi, hola"], ["how are you", "como estas"], ["sorry", "lo siento"], ["thank you", "gracias"], ["please", "por favor"], ["how are you doing today"], ["como estas hoy"], ["I love you", "te amo"], ["hey, eh"], ["welcome", "bienvenido"], ["my name is", "mi nombre es"], [ "good morning", "buenos dias"], ["goodbye","adios"], ["i don't know", "no se"], ["help", "ayudame"], ["happy birthday", "feliz cumpleanos"]] function capitalize (str) { return str.charAt(0).toUpperCase() + str.substring(1); } function translate (text) { for (var i = 0; i < PHRASES.length; i++) { var toReplace = new RegExp("\\b" + PHRASES[i][0] + "\\b", "i"); var index = text.search(toReplace); while (index != -1) { if (text.charAt(index) >= "A" && text.charAt(index) <= "Z") { text = text.replace(toReplace, capitalize(PHRASES[i][1])); } else { text = text.replace(toReplace),PHRASES[i][1]); } index = text.search(toReplace); } } return text; } </script> </head> <body> <form name = "ButtonForm"> <p> Enter a word or phrase </p> <input type = "text" name = "input" value = "" /> <br></br> <input type = "button" value = "Translate" onClick = "translate();" /> <br> </br> </form> </body> </html> Reply With Quote 02-03-2015, 10:12 PM #2 jmrker View Profile View Forum Posts Senior Coder Join Date Aug 2006 Location FL Posts 3,175 Thanks 39 Thanked 510 Times in 504 Posts I have not tested your entire array of words, but this should get you started. NOTES: 1. You did not pass a word to 'translate()' for it to check 2. You did not have a place to store the returned value of the translation 3. You should not use reserved words as variables (ie, text as a function parameter) Code: <html>

BTW, you should enclose your script between [ code] and [ /code] tags (without the spaces) to retain formatting and make it easier for forum members to read, test, debug, etc. Good Luck! Hi guys, i would like a script that detects if quicktime is installed like this one here http://developer.apple.com/internet/...lplugins.shtml but i want it to offer the link to quicktime if not installed, and continue to load the player if quicktime is installed. Im thinking something like this.. Code:
<script type="text/javascript"
src="http://developer.apple.com/internet/webcontent/examples/detectallplugins.shtml "></script>
<script>
if (detectQuickTime == true) {
setTimeout('Redirect()',0);
}
else
{
setTimeout('Redirect2()',0);
}
function Redirect()
{
location.href = 'http://www.mysite.com/player.htm';
}
function Redirect2()
{
location.href = 'http://www.mysite.com/error-install-quicktime.htm';
}
</script>
But i cant make it work. Can anyone help? I have an html page that contains a div that has overflow:auto. Is there a way to detect if the scrollbar is displayed on the div? If the scrollbar is present then I want a message to be displayed inside another div. If there is no scrollbar then I don't want any message to appear. Thanks Is it possible to detect keystrokes on the keyboard? I want to detect the arrow keys in particular. I'm going through the online reference links in the sticky now, great resource! I am trying to detect the parent URL on a page for a Facebook application so that if the user is on my site rather than accessing the application via Facebook they will be redirected to the FB App page. In PHP I can use: if(strstr($parenturl,"mysite.com")){header("location:fbapp.com");exit;} Is it possible to do this in JS also? Because with FB Apps the URL is not always the same so instead of detecting a full URL I just want to search for my domain name within document.location.href to see if it exists and IF yes > Redirect back to FB. I want to detect the double-press of the space key. However, I want a single press of a space key to have a different function. The double-tap of space should only count if the taps of space are no more than, say, a half second apart. For example: The user hits space once, and javascript begins performing one action. 1/3rd of a second later, they hit the space bar again, and since that is within our threshold of 1/2 of a second, the action that began because the user hit the spacebar once should be cancelled, or undone (which I can write later) and the action when the user hits the spacebar twice should begin. Anyone have an idea how to do this? Thanks! Hi, I have do a calculation when an user enters the value in the textbox during onblur event. But during the onblur event I need to capture the tabkey (keyCode) and if it is 9 do the calculate else not do that. But the problem is we cannot detect a keyCode for tab in onblur. But for sure I need to use onblur in this case and cannot use onkeydown as this will have impact on the UI screen for this particular scenario. How to go about this? in the textbox I am calling onblur = "test()" Please provide a helping hand. Thanks. Hi, Wondering if anyone can help me out with some javascript. How do I check upon clicking a random object on the page that the object onmousedown is an image or not? Any help is much appreciated. -cantonboi I have an input box and I want it to function so that when the user presses the enter/return key, it runs a js function. I have the following code: Code: input.onkeydown = function () {
if (event.keyCode === 13) {
// do something
}
}
This works in Safari, Opera, Chrome, and even IE, but not in firefox. Any idea how I could fix this? Thanks, Julian Hi there. I'm considering using the script below to detect the screen resolution of the user and then call a specific CSS for that user. The main aim is so that I can design the website at a fixed width for a larger resolution (used by most people), but if the user has a 980px resoltion then they can be catered for as well. Code: <SCRIPT language="JavaScript">
<!--
if ((screen.width>=1024) && (screen.height>=768))
{
window.location="highres.html";
}
else
{
window.location="lowres.html";
}
//-->
</SCRIPT>
I don't want to use liquid layouts as I think it looks messy, and I don't want to design to a width of 960px as I don't like the blank space at the sides on larger resolutions. Is this an acceptable method, or do you think i'll run into problems? Any advice would be great. Cheers. Pat. Hello there, This seems to be a bit of a sore topic on the forums but at least I think I have good reason for wanting to do it - I've written a script that displays tooltips when your mouse hovers over a link - all this is fine, but when I click on the link and move to another page, then click the back button on the browser to go back, the tooltip for the link I clicked is still visible! It'd be great if there was a way of detecting the button had been pressed so that I can hide it... p.s. I tried onclick = "tooltips.hideToolTip(4); return true;" for the links but no joy... Many thanks Edd I am new to Javascripting but am teaching myself and have written this script from my portfolio site in an effort to detect the users screen resolution so that my art is viewed properly. I have ran the code through a debugger and it has comback as "free of errors" but when I run the webpage on my local machine it does nothing, the page displays as if I had written nothing and due to my limited knowledge of Javascript I am at a loss and hoping for someone to say, "look you screwed this part up fix this and it's good to go"... I'm hoping. Thank You all in advance.. Here is the code Code: <script language="Javascript">
function detect(){
if(screen.width<1280||screen.height<720){
alert("This web page is best viewed with a screen resolution of 1280 by 720 or higher. Your current resolution is "+screen.width+" by "+screen.height+". If possible please change your resolution.")
}
else{
alert("Whoa, you have a high resolution. Nice Job!")
}
}

Is it possible to call a function when user clicks on an (x,y) point (or a small area). I can't place a new object and just set the "onclick" value, so is it possible to do it without that? Thanks for the help. function doUnload() { if (window.event.clientX < 0 && window.event.clientY < 0) { alert("Window is closing..."); } } i get window.event undefined by using var evt =window.event? event : e i get e undefuned var evt =window.event? event : e if (evt.clientX < 0 && evt.clientY < 0) { alert(evt.clientX +"Window is closing..."); } Hi i want to find out the idle time when there is no http request is going on... i dont want to track any mouse or key board events... i dont want that... i read these thread but it is only about screen idle time http://www.codingforums.com/showthre...t=33068&page=2 i am trying to track the time when there is no transaction going between client and server and no http request is sending . if i will get that time then that time i can use to load my additional javascript files... so further transaction of user will become speed up.... i appreciate your help THANKS URL: https://medicard1.com/services.html Site also employs CodeIgniter from original developer. Code below sets up a table with a form and script in separate cells of the same row. Looks good and click on check box works ok, but script seems to only run when the page is initially loaded. Does not change variable 'c' and display the change. Am in a bind for this one. My developer is away for the holiday and CEO wants it done ASAP. Anyone have an idea? <!-- Setup a table to hold the elements where I want them without conflicting with CodeIgniter - K.I.S.S.--> <table style="border:0px;"> <tr> <td style="width:600px; text-align:left;"> <!-- Un-submitted form with legend and checkbox input to acknowledge terms and display discount code --> <form name="acknowledge" action="" method=""> <legend>I acknowledge that I have read and understand the content of this page <!-- onClick should execute display_code() script --> <input style="border:0px; width:40px;" type="checkbox" name="investor" onClick="display_code()"/> </legend> </form> </td> <td style="width:200px; text-align:right;"> <!-- Script should check checked state of checkbox investor and set c to appropriate value --> <script type="text/javascript"> <!-- set c="" after get this working --> var c="NOT SET"; function display_code() { if (document.acknowledge.investor.checked) { var c="INVESTOR"; } else { <!-- set c="" after get this working --> var c="NO CODE"; } } document.write('Your code is: ' + c); </script> </td> </tr> </table> Hi, I'm writing a page scraper in javascript which involves loading a page to scrape, detecting when the page has loaded successfully and then scraping the data. I can get the 'page loading detection' to work if I load the page in a sub-frame. But this is no good as some sites include frame-buster code which breaks my scraper and I cant get any of the framebuster-buster solutions to work. So instead I decided to look at loading the page in a separate tab. Does anyone know how to reliably detect when a page has finished loading in a tab please? I am using Firefox only and I dont mind if the solution requires some extension or greasemonkey script (I have already added the configuration/commands to allow access to pages from different domains). The code below shows an attempt. It sometimes detects when the initial page has loaded but when I press 'submit' it doesnt detect the second loading. Thanks. Code: <html>
<head>
<script type="text/javascript">
currentPageObj = window.open("http://www.bbc.co.uk", "currentPage");
currentPageObj.addEventListener("load", function(){alert("loaded")}, false);
</script>
</head>
<body>
<form action="http://www.example.com" rel="nofollow" target="currentPage">
<input type="submit">
</form>
</body>
</html>
Hi... Is there anyway to differentiate between refreshing a window and closing the browser. It seems both events are handled by onUnload event. Thanks |
