JavaScript - How To Display Words In Red And Green
Similar TutorialsI'm just starting out learning and have sort of given myself a couple of basic problems to solve. I pretty quickly found something that's apparently hard to Google. I've made a page that shows a counter number, starting at 0, with buttons that will increase or decrease the number by 1 or 10. So I'd like to figure out how to show that number in red when it is a negative number and in green when it is a positive number. I've tried a couple of things, including an if... else, but here's my latest crack: Code: var counter=0;
function countUp() {
lastCounter=counter;
counter++;
display();
}
function countDown() {
lastCounter=counter;
counter--;
display();
}
function tenUp() {
lastCounter=counter;
counter+=10;
display();
}
function tenDown() {
lastCounter=counter;
counter-=10;
display();
}
function lastNumber() {
counter=lastCounter
document.getElementById("number").innerHTML=lastCounter;
}
function display () {
number=counter+'';
switch(counter) {
case counter== 0;
document.getElementById("number").innerHTML=number.fontcolor(white);
break;
case counter> 0;
document.getElementById("number").innerHTML=number.fontcolor(green);
break;
case counter< 0;
document.getElementById("number").innerHTML=number.fontcolor(red);
break;
} //end switch
} //end display
I suspect that what I'm doing totally wrong has to do with how I'm describing the case or with calling one function inside another function, since it works up until I start messing with that (had the document.getElementByID stuff in the countUp, countDown, etc., functions before) but I don't know. Thanks in advance for any help you can offer. I've set up a mock registration form page so I can learn a bit about javascript's form validation. (newbie) I want to try to attempt to style the border of a form field green when the user enters the correct info into the form text field and red on all other fields if the user doesnt enter any info into them. When i test it, enter the right info into the username field, leave the others blank, and hit the submit button it styles the username field green ok but it doesnt make the next fields (password and so on) red. Could someone please explain what I am doing wrong? here is my code so far... Note: just for testing purposes I've put return false on everything so it displays a message when everythings ok. Code: ....
<script type="text/javascript">
window.onload = function() {
document.forms[0].username.focus();
}
function validate(form)
{
var form = document.getElementById("reg");
var e = document.getElementById("error");
e.style.background = "red";
for(var i = 0; i < form.elements.length; i++)
{
var el = form.elements[i];
if(el.type == "text" || el.type == "password")
{
if(el.value == "")
{
e.innerHTML = "Please fill in all fields!";
el.style.border = "1px solid red";
el.focus();
return false;
} else {
el.style.border = "1px solid green";
return false;
}
}
}
var un = form.username;
un.value = un.value.replace(/^\s+|\s+$/g,"");
if((un.value.length < 3)|| (/[^a-z0-9\_]/gi.test(un.value)))
{
e.innerHTML = "Only letters,numbers and the underscore are allowed (no spaces) - 3-16 characters";
un.focus();
return false;
}
var pw = form.password;
pw.value = pw.value.replace(/^\s+|\s+$/g,"");
if((pw.value.length < 3) || (/[^a-z0-9]/gi.test(pw.value)))
{
e.innerHTML = "Only letters and numbers are allowed (no spaces) - 3-16 characters";
pw.focus();
return false;
}
e.innerHTML = "You filled in all the fields, well done!";
e.style.background = "green";
return false;
}

Hello! I have an array of strings, like this: var strings= [ "car", "black", "word", "small", "paper", "doom", "elemental", "sword", "mouse" ]; Now i got a function newgame() and i wanna display random word from this array in rectangles gray styled... Here is the problem. I can make to display random words, but i dont know how i make this words with the css style together - rectangels around a char. But the words are different length so i dunno? When i press newgame button, i want for example to random a word from the array: for example word "paper" then i want it to be displayed like this [p] [a] [p] [e] [r], where [ ] are rectangels around the chars ( with the css style, like this: border: 1px solid #000; width:10px; background-color:gray; text-align:justify; padding: 5px 10px; i make a gray rectangle border around the char, but how can i make it work with random words? How can i make it work? Any help please! Hi Someone know any script for division of words into syllables? Regards stickers Hi guys, Do you know a function for banning certain words being inputted by the user eg I want to stop a user uploading offensive words and code tags like <script>, <div> etc.. and messing with the site display Thanks Is there any way to convert a number stored as a javascript variable into words? Something like... Code: var num=120394; then run that var through a function and have the output be: One hundred twenty thousand three hundred ninety four Any help would be great! I want to create a web form that can substitute words in a URL with the inputted values. I realize the form is easy in HTML, and that's about all I'm good for. But I think the substitution must be done by javascript. For example: example.com/whatever/XXX/YYY I want the form to be able to replace the "XXX" and "YYY" with inputted values of the form, then I want it to direct to that URL when I click the "submit" button. Or just output the new URL as a link, whichever is easier. I know this has to be very basic javascript that is easy to do but I know next to nothing about this kind of thing. Sorry for the noob question but hours of googling/trying to figure out basic javascript has left me at a loss still. Help greatly appreciated! I'm trying to find a much simpler way than this current script I am using to generate and print a random word. I don't want to have to name each word but instead just include a very large list of about 300,000 words that javascript uses to pull a random word out of. Can you please help me out?? The list of words I have is a straight list with no commas or anything. I am currently outputting to a text box, but I am looking to generate words according to users input. For example, a user wants 500 words starting with the letter "b" and is less than 5 characters long appended to the character "de." Any help would be awesome! Even a right direction. I'm also willing to pay some for such a script if need be. Thanks! Here's my code: Code: <SCRIPT LANGUAGE="JavaScript">

Hello, I have a regular expression that returns multiple matches. For e.g. If the user types a string "980ee,34223,werw" in a textbox, the regular expression match returns "ee" and "werw". I would like to highlight both "ee" and "werw" in the textbox. How can I achieve this? Thank you. I have the 10000th word and I want to put the this symbols [ and this ] the beginning and end of words .. so my question is .. how do I put the symbol is simultaneously the 10000th word that is .. there is not any program that can do such ... please help .. example : [can] [you] [me] [and] [ask] [google] [yahoo] [and over 10000 ++ more] Sorry, not sure if I need Javascript for this so I posted it in the html forum as well I'm looking to create a simple page where a user can copy and paste a list of ingredients and then push a button to search that list for a number of key words. Key words: Amodimethicone, Trimethylsilylamodimethicone, Glycerin, Trideceth-12, Behenoxy, Bisamino, Aminoethyl, PG-Propyl, Phenylpropyl, Methicone, Cyclomethicone, Cyclopentasiloxane, Cyclohexasiloxane, Cyclopentasiloxane, Dimethiconol, Trimethylsiloxysilicate, Silicate, Siloxy, Trimethylolpropane, Diisostearoyl, Copolyol, Dodecylbenzenesulphonate, Diphenyl, silicone, Methicone, Simethicone, Trisiloxane, sulfate, Myreth, Lauryl, Laureth, Sulfonate, dodecylbenzenesulfonate, Xylenesulfonate, Ammonium, Isethionate, Sulfoacetate, Sarcosinate, Sulfosuccinate, Carboxylate, Taurate, glycinate I don't care how they are alerted if any of the key words match their ingredients pop up, highlight, whatever. *Incase anyone is wondering it is to search hair products for any form of silcones or sulfates since many people wish to avoid them but they come in many different forms. Thanks!! Hello, I wanted to know how can I go through all the text on a page and store a unique ocurrence of every word in a array. Just point me on the right direction if you may. Got lost in translation... Lg Hello. I want to validate via javascript an input text box. What i want is to have at least two words ( not letters ).

How can I truncate all words greater than 30 characters using a class name when the page loads? Been trying to do this for about 5 hours. Trying to conside the following: * Truncate long words and churn anything above the minimum length with an ellipse. * Only truncate words and not the whole sentence or paragraph. * Should truncate text that are inside HTML tags and not truncate the tags themselves. * When you hover over the ellipse, it will show you the complete word. * The long words are already truncated when the page load (SEO friendly). * Block of text are included in a max of 25 <div> elements and a minimum of 1. That's why I'm not using ID. So far I have this lines of code: Code: <script charset="utf-8" language="javascript" type="text/javascript">
function test(gaz) {
var sbText = gaz.innerHTML;
var sbTextArr = sbText.split(' ');
var tempText = "";
for (var s=0; s<sbTextArr.length; s++) {
if (sbTextArr[s].length > 30) { sbTextArr[s] = "marco"; }
gaz.innerHTML = "";
tempText = tempText + " " + sbTextArr[s];
gaz.innerHTML = tempText;
}
}</script>
<div class="myClass" onmouseover="test(this);"><p>This is a <strong>looooooooooooooo</strong><em>ooooooooooooooooooooooooooooooong</em> word.</p></div>
<div class="myClass" onmouseover="test(this);">A text without long word.</div>
<div class="anotherClass"><p>Another set</p><p>But should not affect if there's a loooooooooooooooooong word.</p></div>
I got this from the web and modified it but not working as I intended it to be. Useful for posts in forums, blog comments, and guestbooks Hi, i know i should have 2 fields for a first and last name in my form but i dont - and was wondering if someone would be able to help me with - or has - a java script valadation rule to only allow a one letter character (letter in between spaces such as a middle initial) in a text field if at least 2 words are also included (2 words of at least 2 or more characters) so if the user input ' John H ' an error prompt would display until one more word is added/at least 2 words are found right now im using the below coding to allow at least 2 words in the text field but would like to see if its possible to enhance it so it will only block a one letter word if there are less than 2 other words in the form - right now if any words is added with less than 2 characters it will display an error... if anyone knows of a better form of code that needs a minimum of 2 words added and still allows single characters such as middle initials to in a validation script i'd greatly appreciate your help... i get lost on validation process' 'cheers' in advance to anyone that may know of something or a site that can point me in a better direction function(value,element){return this.optional(element)||/^((\b[a-zA-Z]{2,80}\b)\s*){2,}/ Hi all, as the title says i am trying to keep count of the number of words a user has typed into a textbox. I have an emoticon box, something like the one that you see when you reply/start a thread here. The mouseup event fires off when the user clicks on an emoticon to display it in the textbox. The problem here is, my code below does not start counting if an emoticon is added when theres nothing in the textbox (making the emoticon the first item). I can continue to add more smileys in and they will be counted in the word limit, but the first one will not be included in the count, unless the user clicks somewhere on the screen. How can i fix this problem? Code: //#message is the textbox
$(document).ready(function()
{
var characters = 100;
$("#remainder").append(characters+"words left");
$("#emoticonsbox").mouseup(function()
{
var remaining = characters - $("#message").val().length;
$("#remainder").html(remaining+"words left");
});
});
