javascript - Image preview not working properly -

-

i have code shows image before uploading not working shows image if there no height or width set if try fix height , width same dimensions doesn't works properly

<?php echo    '<input type="file" id="changeme" name="file" multiple/>     <div id="output"></div>     </div>     <div id="right">     <script>     function fileload(e)     {         var files=e.target.files || e.datatransfer.files         (var i=0, f; f=files[i]; i++)         {             parsefile(f)         }     }     function parsefile(file)     {     var reader=new filereader();     reader.onload=function (e)     {         var output=document.getelementbyid("output");         output.innerhtml +="<img src=" + e.target.result + " />";     }     reader.readasdataurl(file);      }     if(window.file && window.filelist && window.filereader)     {         var fileselect=document.getelementbyid("changeme");         fileselect.addeventlistener("change", fileload);     }     </script>'; ?>

it works fine way when enter dimensions height="50" , width="50" in image tag image doesn't show tried using css image doesn't work. note:- have use inside php reasons

i think it's because don't wrap in quotes values <img> tag. try this:

output.innerhtml +="<img src=\'" + e.target.result + "\' style=\'width: 50px; height: 50px;\' />";

note escaped single quotes avoid problems in php echo
