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!

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
