Letter Shadows from User Input - javascript

Goal: User types name into user input field, selects Animate button, and name is printed vertically with each letter containing a drop shadow of each letter. The Javascript library Raphael may be desirable.
Problem: So far what I have is the name being printed vertically twice side by side. Obviously the second column should be the letters as drop shadows, but I don't know how to change the style of them to look like shadows.
My manager gave me one hint: "I had to create a 2nd text line placed underneath the text...and I used the .blur() method on it. If I have to give you another hint I'll be hinting you to the door."
I'm in some real trouble here. If anyone has suggestions, solutions, anything it would be very much appreciated.

Do you really need raphael? What I did was simply print out your words onto an element and get the shadow with css's text-shadow. To get the vertical text I added a </br> after each letter.
Take a look at the fiddle: http://jsfiddle.net/joplomacedo/wVGbF/
Here's the code in case you can't see the fiddle:
HTML
Text: <input type="text" id="words" value="" />
<input id="animateBtn" type="button" value="Animate" />
<div class="print"></div>
CSS
.print {
font: 44px/0.8em "Lobster", cursive;
color: gold;
text-shadow: 2px 2px 3px rgba(0, 0, 0, 0.6);
}​
JS
var join = Array.prototype.join;
$('#animateBtn').on('click', function() {
var txt = $('#words').val(),
spaced_txt = join.call(txt, "</br>");
$('.print').html(spaced_txt);
});​

Here is also the text output function with Raphael:
function draw_text() {
var txt = document.getElementById("words").value;
var posy = txt.length*10;
r.clear();
var attr = {font: "50px Helvetica", opacity: 0.5};
var text = r.text(40, 40+posy, txt).attr(attr).attr({fill: "#0f0"}); // underlayer or "shadow"
text.attr({transform: "r270"}); // rotate 270 degrees
var text2 = r.text(43, 43+posy, txt).attr(attr).attr({fill: "#aa0"}); // text above
text2.attr({transform: "r270"}); // rotate 270 degrees
r.safari();
}
var r = new Raphael("draw-here-raphael");
The full script, based on this example, is here.

How to change style of each character of input text

Here I want to randomly change the CSS of each character of text.
Like if I input Stack I will get S in red, t in blue, a in green... etc on the bottom of the input field.
var myModel = {
name: "Mayur",
};
var myViewModel = new Vue({
el: '#my_view',
data: myModel
});
span{
color:green;
font-weight:600;
font-size:20px;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/1.0.26/vue.min.js"></script>
<div id="my_view">
<label for="name">Enter name:</label>
<input type="text" v-model="name" id="name" name="name" />
<p>Welcome, <span>{{ name | uppercase }}</span></p>
</div>
I haven't worked with Vue and I'm not familiar with its internal events and processes, but here's a tiny prototype i made in plain JavaScript:
document.querySelector('button').onclick = function (){
let span = document.querySelector('span.letters'),
text = span.textContent;
span.innerHTML = '';
Array.from(text).map(function(l){
let color = document.createElement('span');
color.innerHTML = l;
color.style.color = 'rgb(' +
randInterval(0, 255) + ',' +
randInterval(0, 255) + ',' +
randInterval(0, 255) + ')';
span.appendChild(color);
});
}
function randInterval(min,max)
{
return Math.floor(Math.random()*(max-min+1)+min);
}
<div><span class="letters">STACK</span></div>
<button>Random colors</button>
I've purposefully placed the function that randomizes each value of rgb() in a function, so you can alter it easily (now the colors are trully random). If you want to make the darker, you need to lower the max values. If you want the colors lighter, you need to increase the mins.
Html:
<div>Type something here, then click on the white space beneave.</div>
<input type="hidden" id="hidden">
Javascript:
$("div").prop("contentEditable", true).blur(function(){
var chars = $(this).text().split("");
$("#hidden").val($(this).text());
this.innerHTML = "";
$.each(chars, function(){
$("<span>").text(this).css({
color: "#"+(Math.random()*16777215|0).toString(16)
}).appendTo("div");
});
});
Css:
div{
border: 1px solid black;
width: 400px;
height: 20px;
padding: 2px 3px;
overflow: hidden;
}
You can visit http://jsfiddle.net/DerekL/Y8ySy/ for the implementation!
Both html and css codes are given in the link.
It gives the colour to the characters randomly but it can be manipulated easily or if you want them to run randomly, you can use it directly.

Formatting InnerHtml Text with RegEx not working properly

Technology: Asp.Net 4.5 WebForms
I am using the following javascript function to color text in a code block. It actually works if I halt the code with an alert immediately after the function. But the regex rendering doesn't stick. How can I get the results to render after function is completed? Below is a small sample.
CSS
<style type="text/css">
.blue
{
color: blue;
}
.demo
{
background-color: gainsboro;
width: 300px;
height: 100px;
padding: 5px;
}
</style>
JavaScript
<script type="text/javascript">
function Prettyfy() {
var keys = ["Dim", "As", "String"]
for (var i = 0; i < keys.length; i++) {
var value = keys[i];
var str = document.getElementById("demo").innerHTML;
var regexExpression = "(?!(?:[^<]+>|[^>]+<\\/a>))\\b(" + value + ")\\b";
var regex = new RegExp(regexExpression, "ig");
document.getElementById("demo").innerHTML = str.replace(regex, '<span class="blue">' + value + '</span>');
}
alert(document.getElementById("demo").innerHTML);
}
</script>
HTML
<body>
<form id="form1" runat="server"> <pre id="demo" class="demo">
<code>
dim motor as string
dim reducer as string
</code>
</pre>
<br />
<button onclick="Prettyfy()">Prettyfy Code</button>
</form>
</body>
The problem is very likely to be that your form is causing the page to be repainted by default. Add a "type" attribute to your <button>:
<button type=button onclick="Prettyfy()">
(It's not clear why there's a form at all.)

show more/Less text with just HTML and JavaScript

I am needing to create a show more/less text function, but with just JavaScript and HTML.. I can't use any additional libraries such as jQuery and it can't be done with CSS. The sample code I have added displays the 'more' text, but not the 'less'.
If someone could point me in the right direction, it would be much appreciated.
I've spent the majority of the day frying my brain over this, as its clearly not the modern way to do it, however, my HTML is:
<html>
<head>
<script type="text/javascript" src="moreless.js"></script>
</head>
<body>
Lorem ipsum dolor sit amet
<p>
<p id="textarea"><!-- This is where I want to additional text--></div>
</p>
<a onclick="showtext('text')" href="javascript:void(0);">See More</a>
<p>
Here is some more text
</body>
</html>
and my JavaScript is (moreless.js):
function showtext()
{
var text="Here is some text that I want added to the HTML file";
document.getElementById("textarea").innerHTML=text;
}
My answer is similar but different, there are a few ways to achieve toggling effect. I guess it depends on your circumstance. This may not be the best way for you in the end.
The missing piece you've been looking for is to create an if statement. This allows for you to toggle your text.
More on if statements here.
JSFiddle: http://jsfiddle.net/8u2jF/
Javascript:
var status = "less";
function toggleText()
{
var text="Here is some text that I want added to the HTML file";
if (status == "less") {
document.getElementById("textArea").innerHTML=text;
document.getElementById("toggleButton").innerText = "See Less";
status = "more";
} else if (status == "more") {
document.getElementById("textArea").innerHTML = "";
document.getElementById("toggleButton").innerText = "See More";
status = "less"
}
}
With some HTML changes, you can absolutely achieve this with CSS:
Lorem ipsum dolor sit amet
<p id="textarea">
<!-- This is where I want to additional text-->
All that delicious text is in here!
</p>
<!-- the show/hide controls inside of the following
list, for ease of selecting with CSS -->
<ul class="controls">
<li class="show">Show</li>
<li class="hide">Hide</li>
</ul>
<p>Here is some more text</p>
Coupled with the CSS:
#textarea {
display: none; /* hidden by default */
}
#textarea:target {
display: block; /* shown when a link targeting this id is clicked */
}
#textarea + ul.controls {
list-style-type: none; /* aesthetics only, adjust to taste, irrelevant to demo */
}
/* hiding the hide link when the #textarea is not targeted,
hiding the show link when it is selected: */
#textarea + ul.controls .hide,
#textarea:target + ul.controls .show {
display: none;
}
/* Showing the hide link when the #textarea is targeted,
showing the show link when it's not: */
#textarea:target + ul.controls .hide,
#textarea + ul.controls .show {
display: inline-block;
}
JS Fiddle demo.
Or, you could use a label and an input of type="checkbox":
Lorem ipsum dolor sit amet
<input id="textAreaToggle" type="checkbox" />
<p id="textarea">
<!-- This is where I want to additional text-->
All that delicious text is in here!
</p>
<label for="textAreaToggle">textarea</label>
<p>Here is some more text</p>
With the CSS:
#textarea {
/* hide by default: */
display: none;
}
/* when the checkbox is checked, show the neighbouring #textarea element: */
#textAreaToggle:checked + #textarea {
display: block;
}
/* position the checkbox off-screen: */
input[type="checkbox"] {
position: absolute;
left: -1000px;
}
/* Aesthetics only, adjust to taste: */
label {
display: block;
}
/* when the checkbox is unchecked (its default state) show the text
'Show ' in the label element: */
#textAreaToggle + #textarea + label::before {
content: 'Show ';
}
/* when the checkbox is checked 'Hide ' in the label element; the
general-sibling combinator '~' is required for a bug in Chrome: */
#textAreaToggle:checked ~ #textarea + label::before {
content: 'Hide ';
}
JS Fiddle demo.
Try to toggle height.
function toggleTextArea()
{
var limitedHeight = '40px';
var targetEle = document.getElementById("textarea");
targetEle.style.height = (targetEle.style.height === '') ? limitedHeight : '';
}
This is my pure HTML & Javascript solution:
var setHeight = function (element, height) {
if (!element) {;
return false;
}
else {
var elementHeight = parseInt(window.getComputedStyle(element, null).height, 10),
toggleButton = document.createElement('a'),
text = document.createTextNode('...Show more'),
parent = element.parentNode;
toggleButton.src = '#';
toggleButton.className = 'show-more';
toggleButton.style.float = 'right';
toggleButton.style.paddingRight = '15px';
toggleButton.appendChild(text);
parent.insertBefore(toggleButton, element.nextSibling);
element.setAttribute('data-fullheight', elementHeight);
element.style.height = height;
return toggleButton;
}
}
var toggleHeight = function (element, height) {
if (!element) {
return false;
}
else {
var full = element.getAttribute('data-fullheight'),
currentElementHeight = parseInt(element.style.height, 10);
element.style.height = full == currentElementHeight ? height : full + 'px';
}
}
var toggleText = function (element) {
if (!element) {
return false;
}
else {
var text = element.firstChild.nodeValue;
element.firstChild.nodeValue = text == '...Show more' ? '...Show less' : '...Show more';
}
}
var applyToggle = function(elementHeight){
'use strict';
return function(){
toggleHeight(this.previousElementSibling, elementHeight);
toggleText(this);
}
}
var modifyDomElements = function(className, elementHeight){
var elements = document.getElementsByClassName(className);
var toggleButtonsArray = [];
for (var index = 0, arrayLength = elements.length; index < arrayLength; index++) {
var currentElement = elements[index];
var toggleButton = setHeight(currentElement, elementHeight);
toggleButtonsArray.push(toggleButton);
}
for (var index=0, arrayLength=toggleButtonsArray.length; index<arrayLength; index++){
toggleButtonsArray[index].onclick = applyToggle(elementHeight);
}
}
You can then call modifyDomElements function to apply text shortening on all the elements that have shorten-text class name. For that you would need to specify the class name and the height that you would want your elements to be shortened to:
modifyDomElements('shorten-text','50px');
Lastly, in your your html, just set the class name on the element you would want your text to get shorten:
<div class="shorten-text">Your long text goes here...</div>
I hope this helps you. Here is the functionality:
When text characters is less than or equal to 12. Then it displays the whole text and also does not display the more/less button
When text characters is more than 12. Displays only 12 characters of the text and also a More button which when pressed, shows the whole text.
When the More button is pressed the button changes to Less

Mozila: String Manipulation
var startStatus = "less";
function toggleText() {
var text = "Here is the text that I want to play around with";
if (text.length > 12) {
if (startStatus == "less") {
document.getElementById("textArea").innerHTML = `${text.substring(0, 12)}...`;
document.getElementById("more|less").innerText = "More";
startStatus = "more";
} else if (startStatus == "more") {
document.getElementById("textArea").innerHTML = text;
document.getElementById("more|less").innerText = "Less";
startStatus = "less";
}
} else {
document.getElementById("textArea").innerHTML = text;
}
}
toggleText();

I'm not an expert, but I did a lot of looking to implement this for myself. I found something different, but modified it to accomplish this. It's really quite simple:
The function takes two arguments, a div containing only the words "show more" [or whatever] and a div containing the originally hidden text and the words "show less." The function displays the one div and hides the other.
NOTE: If more than one show/hide on page, assign different ids to divs
Colors can be changed
<p>Here is text that is originally displayed</p>
<div id="div1">
<p style="color:red;" onclick="showFunction('div2','div1')">show more</p></div>
<div id="div2" style="display:none">
<p>Put expanded text here</p>
<p style="color:red;" onclick="showFunction('div1','div2')">show less</p></div>
<p>more text</p>
Here is the Script:
<script>
function showFunction(diva, divb) {
var x = document.getElementById(diva);
var y = document.getElementById(divb);
x.style.display = 'block';
y.style.display = 'none';
}
</script>
You can also use details HTML tag which does the work for you.

You can used the CSS line-height property to change the spacing between the letters.

JavaScript for loop not changing link text

I have a nested for loop inside a for loop that is supposed to change the link text to a random number between 1 and 5. The ID of the links are "aX_Y", X and Y being numbers. The links are arranged in a 4x3 square. The problem is that the random numbers for the link text is only displayed for the last row:
<!DOCTYPE html>

for(var x = 0; x < 4; x++)
{
for(var y = 0; y < 3; y++)
{
document.getElementById('a' + x + '_' + y).innerHTML = Math.floor(Math.random()*5 + 1);
console.log('a' + x + '_' + y);
}
}

Here is a direct link to it:
https://dl.dropbox.com/u/750932/iPhone/risk.html
This change to your CSS fixes the issue:
a:link, a:visited
{
color: #eee;
border:3px solid #ccc;
text-decoration:none;
display:inline-block;
padding:20px;
}
(Tested in Firefox)
Your Javascript code is fine; all of the grid squares are getting populated with random numbers. What I am seeing instead is that each row of links is overlapping the previous row, so the numbers in the previous row are being hidden.
Is the overlapping intentional?
All the random numbers are being generated correctly. The top 2 rows are just hidden due to your CSS rules. You can prove this by making the following CSS change:
Change the line that looks like this:
a:link, a:visited {color: #eee;border:3px solid #ccc;text-decoration:none;padding:20px;}
to this:
a:link, a:visited {color: #eee;border:3px solid #ccc;text-decoration:none;}
And voila, it's all working beautifully.
Heh, I'm pretty sure it is working...the other boxes are just overlapped by the ones in front and you can't see them. Firebug shows values inside all the boxes.
a {
display:block;
float:left;
}
br {
clear:both;
}
...though actually those top-level elements shouldn't be restyled like that necessarily, I'd put it all in a <div id="game"></div> and make them .game a and .game br.
