i hope can give me how can preview image on popover. thanks

i found solution this, has delay.

i think problem reader.onload returns img-container html first before changing img src.

so did

$('.example-popover').popover({                 trigger: 'hover',                 container: 'body',                 html: true,                 placement:'bottom',                 content: function () {                     var x = $(this).closest('div').find('#rawimage');                     var imgbyte = '';                     if (x[0].files && x[0].files[0]) {                         var reader = new filereader();                          reader.onload = function (e) {                             $('#previmg').attr('src', e.target.result);                         }                          reader.readasdataurl(x[0].files[0]);                     }                     return '<img id="previmg" src="#" style="width:100%"/>'                 }             })

thanks everyone! hopes can reference someone!
