and this is my all code

<input id='demoInput1' onkeyup="demo1()" />

<div id='demoDiv1' class='resizable'></div>

<script>


function demo1() {
	
    var div = document.getElementById('demoDiv1');
    var input = document.getElementById('demoInput1');
	
 	div.innerText = input.value;
	
    resizeContents();
	
	var content = input.value;  

	alert(div.innerText.replace(/(.{10})/g, "$1<br>"));

}




function resizeContents() {
	
    var resizableDivs = document.getElementsByClassName('resizable');
	
    for (index = 0; index < resizableDivs.length; ++index) {
        var div = resizableDivs[index];
        if (div.innerText != '') {
            var divWidth = div.clientWidth;
            var divHeight = div.clientHeight;

            var contentWidth = div.scrollWidth;
            var contentHeight = div.scrollHeight;

            var fontSize = div.style.fontSize;
            fontSize = Number(fontSize.substring(0, fontSize.length - 2));

            while (contentWidth <= divWidth && contentHeight <= divHeight) {
                fontSize += 1;
                div.style.fontSize = fontSize + 'px';
                contentWidth = div.scrollWidth;
                contentHeight = div.scrollHeight;
				
            }

             while (contentWidth > divWidth || contentHeight > divHeight) {
                 fontSize -= 1;
                 div.style.fontSize = fontSize + 'px';

                 contentWidth = div.scrollWidth;
                 contentHeight = div.scrollHeight;
             }
        }
    }
	
	
}

If it shows up fine in your alert but not in your div, then the problem lies in how you put the value in the div. You are not showing us how you're doing that so we can't see why it doesn't work, but this line should do the job:

JavaScript

div.innerHTML = input.value.replace(/(.{10})/g, "$1<br>");
