2. js implementation code
-
- function my_formatSize($size){
- var size = parseFloat($size);
- var rank =0;
- var rankchar ='Bytes';
- while(size>1024){
- size = size/1024;
- rank++;
- }
- if(rank==1){
- rankchar="KB";
- }
- else if(rank==2){
- rankchar="MB";
- }
- else if(rank==3){
- rankchar="GB";
- }
- return size.toFixed(2)+ " "+ rankchar;
- }
- ?>
