Thanks once again,for all great mind's.

My expectation is exactly what the they have in example site.

example site:

--->creating text box dynamically onclick in CANVAS area only.

--->text box input text's font,font size,color .. changed by getting id var somename = document.getelementbyid("id of textbox -in this case id getting uniquely"); somename = here all function for changing color, font are follows

but,

my problem is to add text box dynamically onclick button,so how to assing id for var somename = document.getelementbyid("id of textbox(dynamically created text box id)");

At the same time that text box should be movable any were in canvas.

You can create a new HTML element like this:

var textBox = document.createElement("textarea");

To add it to the parent use

document.getElementById([insert id of parent here]).appendChild(textBox);

This parent should be the div/html-element in which all the textareas are located.

Example in JSFiddle

HTML

<div id='parent'>
    <textarea>txt1</textarea>
    <textarea>txt2</textarea>
    <textarea>txt3</textarea>
</div>
<button onClick="addBox()">add textarea</button>

JS

addBox = function(){
    var textBox = document.createElement("textarea");
    document.getElementById("parent").appendChild(textBox);
}

---

Example in JSFiddle with JQuery

HTML

<div id='parent'>
    <textarea>txt1</textarea>
    <textarea>txt2</textarea>
    <textarea>txt3</textarea>
</div>
<button>add textarea</button>

jQuery

$(function(){
    $('button').on('click', function(){
        var textBox = document.createElement("textarea");
        $('#parent').append(textBox);
    });
});

Here the link that you wanted :

JavaScript Version:

HTML

<input id='inp' type='button' value='Click me'/>
<div id='cont'>

</div>

JavaScript

document.getElementById('inp').addEventListener('click', function () {
        var textarea = document.createElement('textarea');
        textarea.className="mytextbox";
        document.getElementById('cont').appendChild(textarea);
    });

Css

.mytextbox{
    width:200px;height:200px;box-shadow:2px 1px 5px 1px #000;

}

---

jQuery Version :

HTML

<input id='inp' type='button' value='Click me'/>
<div id='cont'>

</div>

jQuery

$('input').click(function(){

     var textarea =  $('<textarea></textarea>');
     textarea.css({'width':'200px','height':'200px','box-shadow':'1px 2px 5px 1px #000'});
    $('#cont').append(textarea);

});
