jquery - Is there a way to programmatically determine that an image link is bad? -


in site i'm working on, image displayed not (displayed) because link bad or stale (or whatever). can see here: why dynamic html seemingly randomly placed?

when happens, want able show "image unavailable" message image be. possible? if so, 2 things needed:

1) able determine programmatically image not being displayed 2) replace it, in case, aforementioned message

perhaps (pseudocode):

if (imagemissing) {     $('img').attr('src', 'imagemissing.png'); }

?

update

okay, code should like:

function dosomething() {     var htmlbuilder = '';     $.getjson('duckbills.json', function() {         // each ...         // process json file, building dynamic html         htmlbuilder += 'img="bla.png"...';          $('img').error(function() {              $(this).attr("src", "imagemissing.png");         });     }): }):

???

does cause each image, it's added, have error handler attached it, there n event handlers bound, 1 each image?

or should be:

function dosomething() {     var htmlbuilder = '';     $.getjson('duckbills.json', function() {         // each ...         // process json file, building dynamic html         htmlbuilder += 'img="bla.png"...';     }):     $('img').error(function() {          $(this).attr("src", "imagemissing.png");     }); }):

???

update 2

this code, , doesn't work:

$.getjson('content/nbccjr.json', function (data) {     $.each(data, function (i, datapoint) {         if (isyear(datapoint.category)) {             htmlbuilder += '<div class=\"yearbanner\">' + datapoint.category + '</div>';         } else {              htmlbuilder += '<section class=\"wrapper\" ><a id=\"mainimage\" class=\"floatleft\" href=\"' +                 datapoint.imghref + '\"' + ' target=\"_blank\"><img height=\"160\" width=\"107\" src=\"' +                 datapoint.imgsrc + '\"' +                 datapoint.imgalt + '></img></a>' +                 '<div id=\"prizecategory\" class=\"category\">' +                 datapoint.category +                 '</div><br/><cite id=\"prizetitle\" >' +                 datapoint.title +                 '</cite><br/><div id=\"prizeartist\" class=\"author\">' +                 datapoint.author +                 '</div><br/>';             if (datapoint.kindle.trim().length > 2) {                 htmlbuilder += '<button><a href=\"' + urlize(datapoint.kindle) + '\"' +                     ' target=\"_blank\">kindle</a></button>';             }             if (datapoint.hardbound.trim().length > 2) {                 htmlbuilder += '<button><a href=\"' + urlize(datapoint.hardbound) + '\"' +                     ' target=\"_blank\">hardbound</a></button>';             }             if (datapoint.paperback.trim().length > 2) {                 htmlbuilder += '<button><a href=\"' + urlize(datapoint.paperback) + '\"' +                     ' target=\"_blank\">paperback</a></button>';             }             htmlbuilder += '</section>';                          // doesn't work         $('img').error(function () {             $(this).attr("src", "content/noimageavailable.png");         });     } }); //each

...and don't know why...

sure is, error() method :

$('img').error(function() {     $(this).attr("src", "imagemissing.png"); });

the error event sent elements, such images, referenced document , loaded browser. called if element not loaded correctly.
