JavaScript - Language Characters In String Creating Js Errors
Similar TutorialsHi, So I've got an array called questions_raw Code: questions raw = [
["<Q1> Question",
"choice1","choice2", "choice3"],
["<Q2> Question",
"choice1","choice2", "choice3"],
...
]
And I want to list all of the questions, but not the choices/answers. So far, I've managed to list just the questions, but because another function randomly sorts them, I need to sort them back into numerical order for a separate function (displaying the questions) I use characters (>,^) at the front to separate them into different answer types (just to explain the code) I try this to cut each string down so that they can be sorted numerically/alphebetically - Code: function linearlist()
{
var list = [];
var tempStr = "";
for (var l = 0; l < 145; l++)
{
tempStr = questions_raw[l][0];
list[l] = tempStr;
}
if (list.charAt(0)== " " ) list = list.substring(3) ;
if (list.charAt(0)== ">" ) list = list.substring(3) ;
if (list.charAt(0)== "^" ) list = list.substring(3) ;
var sorted = list.sort();
document.Qtext2form.Qtext2.value = sorted.join("\n");
}
But it doesn't like it - because "it has no method charAt" Any idea what i'm missing? Is it just that you have to put the [l] in every time you call a variable? Cheers How can to obtain length of string variable, for example if I have: var msg = 'hello world!'; Does it exist a method to count string characters? Can some one help me, I want to replace the characters from a string and I have tried with this script: Code: var v5=form.description.value.replace(/#/, "%23"); But it only changes the first character from the string. Turning #### into %23### but I want them all transformed. Here is the code i am trying. Code: var str="اسدف";
patt=/[\u0600-\u06FF\u0750-\u077F]/;
result=patt.test(str);
document.write("<br />Returned value: " + result);
</script>
This should return true, as the string in the str variable is indeed Arabic character. But it returns false. Need some help here on this.. Thanks in Advance I have a problem thats above my head, im new to javascript. I want to be able to control the first three characters of an input string on a login form. If a user types GP15555 or JP15555 I want it to change to GPL5555 or JPL5555 respectively changing the "1" to an "L" on the prefix is this at all possible? any point in the right direction would be great. heres my code Code: </script>
<script language="JavaScript" type="text/javascript">
//<![CDATA[
function Login(form) {
var password = form.password.value;
var pin = form.pin.value;
var product = form.product.value;
if (password) {
var htsite = product + "/" + password + "/" + pin + "/index.html";
window.location = htsite;
}
else {
alert("Please enter your password and pin.");
}
}
// End -->
//]]>
</script>
/thanks gp I need to declare a variable (astString) and initialise it with a string of asterisks. astString needs to be the same length as another variable (otherString). otherString changes it value regularly so I think I need to use the .length property in some way but I can't see how! This should be simple but it's eluding me completely. Is this possible? Code: String.prototype.trim = function(){
return this.replace(/^\s+|\s+$/g, "");
}
var myStr = " Hi what's up? ";
myStr.trim();
alert("{" + myStr + "}"); //will result in the original string, not the trimmed version
It's possible with numbers: Code: var myNum = 10; myNum++; alert(myNum); //11 I need to program a language protocol compatibility patch for multiple OS'. I don't know where to start, I'm new to programming BUT at least I know what is needed. If anyone is willing to help, I'm willing to elaborate.
I'm currently using an automation software to automate a series of steps I perform on my computer. One of the tasks involves hundreds of If/Then loops, extracts text from websites using an embedded web browser, computes equations and write text files. The thing is, in order to share this with somebody else, they also need the same automation software installed, and then need to import it. So it's a process I'm trying to replace by creating a small program with a GUI that involves a simple installation on the user's PC (or ideally without installation). The language must be flexible enough to perform the same actions that I listed above - and more preferably. I'm a complete novice with anything besides HTML/CSS so I'm looking for A flexible programming language that isn't rocket science to learn from scratch and is ideal for small stand-alone programs The ability to create a GUI. I'd be happy to read any good reference you have about the language/design knowledge needed for GUI's.

I know its all a bit sloppy, but Im just trying to rush though so much work... Any help would be great. If everyone is active tonight I probably will be. Normally I dont have this many problems, but I guess its just exam pressure... Cheers 5hifty I would like to ask people's opinions as to which "offline" language is most similar to javascript? I don't program for a living, but I have been learning javascript in my spare time. I would now like to have a shot at making a desktop application, and I think it would help to choose one which is most similar, if at all possible, to javascript? e.g. python, ruby, C#, visual basic ... I have no idea and haven't had much luck googling this Thanks Matt Any one have any idea how to make a Java scorecard... If any one have code than please send me i have to submit it on my project... please help mee...
Hi Folks, I'm developing a software tool that can create the basic software outline (classes, modules, functions) from natural language. (The problem definition document for example) The benefits of a initial software structure are an enhanced software performance, and a greater adaptability later on. I was wondering for what purposes this tool would be interesting? And if an integrating this with a programming language would be interesting, so a pre-programmed code divided over several classes emerges. Best regards, viaBox -=-=-=-=-=-=-=-=-=-=-=-=-=-=- http://budurl.com/ViaBox =-=-=-=-=-=-=-=-=-=-=-=-=-=-= I want to have a browser language detection for 2 languages for Explorer and Firefox and struggle a little to make it work. I don't know really much about JavaScript so I guess I did some grave errors. It works for one language though, but for that I don't really detection. I am not sure if that's wrong, but I try to look for the 'en-' in the language not to deal separately with en-US, en-AU, en-UK etc. PHP Code: <script type="text/javascript"> var str=navigator.language; x = (str.search(/en-/i)); if ( !(x=='-1') ) { document.write("English Mozilla"); } var expl=navigator.browserLanguage; ex = (expl.search(/en-/i)); if ( !(ex=='-1') ) { document.write("Englisch1 Explorer"); } var dm=navigator.language; d1 = (dm.search(/de-/i)); if ( !(d1=='-1') ) { document.write("German Mozilla"); } var dex=navigator.browserLanguage; dexpl = (dex.search(/de-/i)); if ( !(dexpl=='-1') ) { document.write("German Explorer"); } </script> 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 Hi, I'm currently trying to get javascript to work with internet explorer. I managed to get one part of the translation file to work. It's a javascript to change some of the words on Facebook from English to Secwepemc (native american language). The original file works in Firefox and Chrome but not in safari. I knew it was because internet explorer has its own parameters. A file works completely for FF and chrome but not for IE. So, I changed the language a bit so that IE can understand it. Now I have one part of the translation working but not the others. I am wondering if it would be better to use ID's, names, and class all together to get the english words I want to change. I am using grease monkey for IE to use this script. I know firefox and chrome are much better but the plan is for everyone to use and some people still use IE. I know that if I have part of the words translating, then it must be the wrong identifiers. If someone can either help me find the right identifiers or if I missed changing syntax from FF and Chrome to IE, that would be amazing! Here is the javascript file. Code: var es = new Array();
es["Home"] = "Tsitcw";

Hey all, I have a simple example below showing how when I pass in the value of the value attribute of option node, and then use if operator to check whether parameter is a string or not, even though it's a string, it converts it to false boolean and triggers the else statement rather than calling a function: Code: <body> <select> <option value="createMsg">Add Message</option> <option value="removeMsg">Remove Message</option> </select> </body> Code: var menu = {
handleMenu : function(callback){
if(callback === "string"){
menu[callback]();
}
else {
console.log("Issue occurred")
}
},
createMsg : function(){
var content = document.createTextNode("Please give additional information."),
heading = document.createElement("h1");
heading.appendChild(content);
document.body.appendChild(heading);
},
removeMsg : function(){
}
}
document.getElementsByTagName('select')[0].onchange = function(){ menu.handleMenu(this.value)};
callback should be a string so why is it saying otherwise? Thanks for response |
