I try to display text come with typing text effect.i tried like this
<!DOCTYPE html>
<html>
<head>
<script src="http://code.jquery.com/jquery-1.10.2.min.js"></script>
</head>
<body>
<span id="holder"></span>
</body>
<script>
(function($)
{
$.fn.writeText = function(content) {
var contentArray = content.split(""),
current = 0,
elem = this;
setInterval(function() {
if(current < contentArray.length) {
elem.text(elem.text() + contentArray[current++]);
}
}, 100);
};
})(jQuery);
$("#holder").writeText("This is some text");
</script>
</html>
It's work but i need display Paragraph content like this but now to call Paragraph content in writeText.
If it's not good way to display Pragraph like typing effect. Please tell me how to solved my problem .Please give me any idea.
Thanks in Advanced.
i have simply modified your code for this, you just need get the content of each para and pass each para to your writeText function()
Just give class="effect" to to be animated
<!DOCTYPE html>
<html>
<head>
<script src="http://code.jquery.com/jquery-1.10.2.min.js"></script>
</head>
<body>
<span id="holder"></span>
<p class="effect">Hi, this is Gokul Praveen' PARA 1!</p>
<p class="effect">Hi, this is James Bond's PARA 2!</p>
</body>
<script>
(function($)
{
$.fn.writeText = function(content) {
var contentArray = content.split(""),
current = 0,
elem = this;
setInterval(function() {
if(current < contentArray.length) {
elem.text(elem.text() + contentArray[current++]);
}
}, 100);
};
})(jQuery);
$(".effect").each(function(index) {
var text = $( this ).text();
$(this).empty();
$(this).writeText(text);
});
//$("#holder").writeText("This is some text");
</script>
</html>
Execute the code in a browser and check. Don't forget to mark it correct!
I think this fiddle will do the trick

I to replace dot(.) into special character "।" on only dot(.) keypress.
I don't have much knowledge of coding.
I found a function, but when I paste a text file in the text area, it replaces all dots that are present in a text file into special characters "।".
If I am wrong, please edit or suggest the appropriate code in the code.
<!doctype html>

var str = val.replace('.', '।');
$(this).val(str);
});

To replace last . just key in. It does not handle the case when pressing dot and hold.
$(function() {
$('textarea').on("keyup", function(e) {
if (e.key === '.') {
const index = this.selectionStart;
const text = $(this).val();
if (index > 0 && text.charAt(index - 1) === '.') {
$(this).val(text.substr(0, index - 1) + '|' + text.substr(index));
this.selectionStart = index;
this.selectionEnd = index;
}
}
});
});

Replacing the last character if the input was a dot should fix it:
$(this).val($(this).val().replace(/.$/,"|"));

I used animation properties in jquery but i want the loop to display the three image continuously.
I once created a small js plugin that does this, you can see the code here:
$.fn.luckyCarousel = function(options) {
var car = this;
var settings = $.extend( {
'delay' : 8000,
'transition' : 400
}, options);
car.append($('<div>').addClass('nav'));
var nav = $('.nav', car);
var cnt = $("ul", car);
var car_w = car.width();
var carItems = $('li', car);
$(cnt).width((carItems.length * car_w) + car_w);
$(carItems).each(function(i) {
var dot_active = (!i) ? ' active' : '';
$(nav).prepend($('<div>').addClass('dot dot' + i + dot_active).bind('click', function(e) {
slideSel(i);
}));
});
$(carItems).css('visibility', 'visible');
$(cnt).append($(carItems).first().clone());
car.append(nav);
var sel_i = 0;
var spin = setInterval(function() {
slideSel('auto')
}, settings.delay);
function slideSel(i) {
if (i == 'auto') {
sel_i++;
i = sel_i;
} else {
clearInterval(spin)
}
var position = $(cnt).position();
var t = car_w * -i;
var last = false;
var d = t - position.left;
if (Math.abs(t) == cnt.width() - car_w) {
sel_i = i = 0;
}
$(cnt).animate({
left: '+=' + d
}, settings.transition, function() {
$('.dot', car).removeClass('active');
$('.dot' + i, car).addClass('active');
if (!sel_i) {
$(cnt).css('left', '0');
}
});
sel_i = i;
}
}

I am use this code for Writing Text Effect:
<script type="text/javascript">
$(document).ready(function () {
function changeText(cont1, cont2, speed) {
var Otext = cont1.text();
var Ocontent = Otext.split("");
var i = 0;
function show() {
if (i < Ocontent.length) {
cont2.append(Ocontent[i]);
i = i + 1;
};
};
var Otimer = setInterval(show, speed);
};
$(document).ready(function () {
changeText($("#TypeEffect p"), $(".p2"), 150);
});
});
</script>
but its not working for multiline, I use this code:
changeText($("#TypeEffect p, #TypeEffect br"), $(".p2"), 150);
so, its not working.
please help me for Writing Text Effect in multi line.
Try
$(document).ready(function () {
function changeText(cont1, cont2, speed) {
var contents = $(cont1).contents().map(function () {
if (this.nodeType == 3) {
if ($.trim(this.nodeValue).length) {
return this.nodeValue.split("")
}
} else {
return $(this).clone().get();
}
}).get();
var i = 0;
function show() {
if (i < contents.length) {
cont2.append(contents[i]);
i = i + 1;
} else {
clearInterval(Otimer)
}
};
var Otimer = setInterval(show, speed);
};
$(document).ready(function () {
changeText($("#TypeEffect p"), $(".p2"), 150);
});
});

font-family:Courier;
font-size:12px;
color:#24FF00;
background-color:black;

Javascript:
var text = "Help Please, i want help.";
var counter = 0;
var speed = 25;
function type()

lastText+=text.charAt(counter);
counter++;
document.getElementById("writer").innerHTML = lastText;
}
setInterval(function(){type()},speed);
HTML:
<div id="writer"></div>
I want to know how can i use <br> tag (skipping a line or moving to another line). I tried many ways but failed, I want that if I Typed My name is Master M1nd. and then i want to go on the other line how would i go?
I've made a jQuery plugin, hope this will make things easier for you. Here is a live demo : http://jsfiddle.net/wared/V7Tv6/. As you can see, jQuery is loaded thanks to the first <script> tag. You can then do the same for the other <script> tags if you like, this is not necessary but considered as a good practice. Just put the code inside each tag into separate files, then set appropriate src attributes in the following order :
<script src=".../jquery.min.js"></script>
<script src=".../jquery.marquee.js"></script>
<script src=".../init.js"></script>
⚠ Only tested with Chrome ⚠
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
<script>
jQuery.fn.marquee = function ($) {
function findTextNodes(node) {
var result = [],
i = 0,
child;
while (child = node.childNodes[i++]) {
if (child.nodeType === 3) {
result.push(child);
} else {
result = result.concat(
findTextNodes(child)
);
}
}
return result;
}
function write(node, text, fn) {
var i = 0;
setTimeout(function () {
node.nodeValue += text[i++];
if (i < text.length) {
setTimeout(arguments.callee, 50);
} else {
fn();
}
}, 50);
}
return function (html) {
var fragment, textNodes, text;
fragment = $('<div>' + html + '</div>');
textNodes = findTextNodes(fragment[0]);
text = $.map(textNodes, function (node) {
var text = node.nodeValue;
node.nodeValue = '';
return text;
});
this.each(function () {
var clone = fragment.clone(),
textNodes = findTextNodes(clone[0]),
i = 0;
$(this).append(clone.contents());
(function next(node) {
if (node = textNodes[i]) {
write(node, text[i++], next);
}
})();
});
return this;
};
}(jQuery);
</script>
<script>
jQuery(function init($) {
var html = 'A <i>marquee</i> which handles <u><b>HTML</b></u>,<br/> only tested with Chrome. Replay';
$('p').marquee(html);
$('a').click(function (e) {
e.preventDefault();
$('p').empty();
$('a').off('click');
init($);
});
});
</script>
<p></p>

Instead of passing <br> char by char, you can put a \n and transform it to <br> when you modify the innerHTML.
For example (http://jsfiddle.net/qZ4u9/1/):
function escape(c) {
return (c === '\n') ? '<br>':c;
}
function writer(text, out) {
var current = 0;
return function () {
if (current < text.length) {
out.innerHTML += escape(text.charAt(current++));
}
return current < text.length;
};
}
var typeNext = writer('Hello\nWorld!', document.getElementById('writer'));
function type() {
if (typeNext()) setInterval(type, 500);
}
setInterval(type, 500);
Also probably you'll be interested in exploring requestAnimationFrame (http://www.paulirish.com/2011/requestanimationframe-for-smart-animating/), for your typing animation :)
I'm implementing an on-screen Keyboard for a Javascript application. The text should appear in a textarea-Element. I've no problem creating text-events but feel unable to create non-text events such as the Backspace. Here is some sample code:
<html>
<head>
<title>Test Textarea Events</title>
<script type="text/javascript">
function log(text) {
var elem = document.getElementById("log");
if (elem) {
elem.innerHTML += "<br/>" + text;
}
}
function logEvent(e) {
log("Type: " + e.type + ", which: " + e.which + ", keyCode: " + e.keyCode + ", charCode: " + e.charCode + ", keyIdentifier: " + e.keyIdentifier + ", data: " + e.data);
}
function logClear() {
var elem = document.getElementById("log");
if (elem) {
elem.innerHTML = "";
}
}
function sendBackEvent() {
var textarea = document.getElementById("textarea");
if(!textarea) {
return;
}
var ke1 = document.createEvent("KeyboardEvent");
ke1.initKeyboardEvent("keydown", true, true, window, "U+0008", 0, ""); // U+0008 --> Backspace
// how to set "keyCode" and "which"?
// 1. ke1.keyCode = 8; will be ignored due to "writable: false"
// 2. delete ke1.keyCode will be ignored too
// and Object.defineProperty(KeyboardEvent.prototype, "keyCode", ... whatever ...);
// will result in Exception due to "configurable: false"
// 3. generating a more general Event (e.g. "var e = document.createEvent("Events");")
// and setting all necessary props (e.g. "e.initEvent("keydown", true, true);e.keyCode=8;e.which=8;")
// will work, but the textarea will ignore the Event
textarea.dispatchEvent(ke1);
var ke2 = document.createEvent("KeyboardEvent");
ke2.initKeyboardEvent("keyup", true, true, window, "U+0008", 0, ""); // U+0008 --> Backspace
// same question as above
textarea.dispatchEvent(ke2);
}
function init() {
var textarea = document.getElementById("textarea");
if(!textarea) {
return;
}
textarea.addEventListener("keydown", logEvent, false);
textarea.addEventListener("keypress", logEvent, false);
textarea.addEventListener("keyup", logEvent, false);
textarea.addEventListener ("textInput", logEvent, false);
}
</script>
</head>
<body onload="init()">
<textarea id="textarea" name="text" cols="100" rows="20"></textarea><br/><br/>
<button onclick="sendBackEvent()">send BackEvent</button>
<button onclick="logClear()">clear log</button><br/>
<div id="log"></div>
</body>
</html>
The interesting function here is sendBackEvent(). I tried hard to get exactly the same event like pressing the Backspace-Button on the physical Keyboard but didn't succeed.
I know there is a Webkit-Bug but hoped there could be some other way to get this working. Has anyone had the same problem? Could it be solved? How? The proposed solution here (calling new KeyboardEvent(...) ) doesn't work because directly calling the KeyboardEvent constructor results in following exception:
Exception: TypeError: '[object KeyboardEventConstructor]' is not a constructor (evaluating 'new KeyboardEvent(...)')
I have no more ideas.
Since there seem to no way out, i found myself constrained to install my own backspace event handler. The working code (without logging now) is here:
<html>
<head>
<title>Test Textarea Events</title>
<script type="text/javascript">
function sendBackEvent() {
var textarea = document.getElementById("textarea");
if(!textarea) {
return;
}
var ke1 = document.createEvent("Events");
ke1.initEvent("keydown", true, true);
ke1.keyCode = ke1.which = 8; // Backspace
textarea.dispatchEvent(ke1);
var ke2 = document.createEvent("Events");
ke2.initEvent("keyup", true, true);
ke2.keyCode = ke2.which = 8; // Backspace
textarea.dispatchEvent(ke2);
}
function handleBackEvent(e) {
if(e.keyCode != 8) {
return;
}
if (textarea.value.length == 0) {
return;
}
var text = textarea.value;
var selectionStart = textarea.selectionStart;
var selectionEnd = textarea.selectionEnd;
if (selectionStart < selectionEnd) {
var text1 = (selectionStart > 0 ? text.slice(0, selectionStart) : "");
var text2 = (selectionEnd < text.length ? text.slice(selectionEnd) : "");
textarea.value = text1 + text2;
}
else if (selectionStart > 0) {
var text1 = (selectionStart - 1 > 0 ? text.slice(0, selectionStart - 1) : "");
var text2 = (selectionStart < text.length ? text.slice(selectionStart) : "");
textarea.value = text1 + text2;
selectionStart--;
}
textarea.selectionStart = textarea.selectionEnd = selectionStart;
e.preventDefault();
e.stopPropagation();
return false;
};
var textarea;
function init() {
textarea = document.getElementById("textarea");
if(!textarea) {
return;
}
textarea.addEventListener("keydown", handleBackEvent, false);
}
</script>
</head>
<body onload="init()">
<textarea id="textarea" name="text" cols="100" rows="20"></textarea><br/><br/>
<button onclick="sendBackEvent()">send BackEvent</button>
</body>
</html>
Just in case someone else run into same trouble.
