This is the link for the template that i used for the layout design https://getbootstrap.com/.
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8" name="viewport" content="width=device-width, initial-scale=1"/> <link rel="stylesheet" type="text/css" href="css/bootstrap.css"/> </head> <body> <nav class="navbar navbar-default"> <div class="container-fluid"> </div> </nav> <div class="col-md-6 well"> <hr style="border-top:1px dotted #ccc;"/> <div class="col-md-5"> <div class="form-group"> <input type="number" class="form-control" id="number1"/> </div> <div class="form-inline"> <select class="form-control" id="file1" style="width:50%;"> </select> <br /> <br /> <select class="form-control" id="file2" style="width:50%;"> </select> </div> <br /> <div class="form-group"> <input type="text" class="form-control" id="number2" disabled="disabled"/> </div> </div> </div> </div> </body> </html>
function convertFileSize(){ let number=document.getElementById('number1').value; if(number==""){ alert("Please enter something"); }else{ let result; let file1=document.getElementById('file1').value; let file2=document.getElementById('file2').value; if(file1=="Byte" && file2=="Byte"){ result=parseInt(number); }else if(file1=="Byte" && file2=="KB"){ result=Math.round(parseInt(number)/1024) }else if(file1=="Byte" && file2=="MB"){ result=Math.round(parseInt(number)/1024/1024); }else if(file1=="Byte" && file2=="GB"){ result=Math.round(parseInt(number)/1024/1024/1024); }else if(file1=="KB" && file2=="Byte"){ result=parseInt(number)*1024; }else if(file1=="KB" && file2=="KB"){ result=parseInt(number); }else if(file1=="KB" && file2=="MB"){ result=Math.round(parseInt(number)/1024); }else if(file1=="KB" && file2=="GB"){ result=Math.round(parseInt(number)/1024/1024); }else if(file1=="MB" && file2=="Byte"){ result=parseInt(number)*1024*1024; }else if(file1=="MB" && file2=="KB"){ result=parseInt(number)*1024; }else if(file1=="MB" && file2=="MB"){ result=parseInt(number); }else if(file1=="MB" && file2=="GB"){ result=Math.round(parseInt(number)/1024); }else if(file1=="GB" && file2=="Byte"){ result=parseInt(number)*1024*1024*1024; }else if(file1=="GB" && file2=="KB"){ result=parseInt(number)*1024*1024; }else if(file1=="GB" && file2=="MB"){ result=parseInt(number)*1024; }else if(file1=="GB" && file2=="GB"){ result=parseInt(number); } document.getElementById('number2').value = result; } }
In the code above we will only create a method called convertFileSize(), this function will convert the file size you have entered to a specific value. This function contains several conditional statement that handle the conversion for the specific file size.
