How to send image to .net Webservice using Ajax in IE8?

IE 8 does not have formdata, you can use a hidden iframe and post it and read the results. I've used a technique that was something like this Clone the form, move original form into a hidden iframe (this needs to be done because you cant clone or set input type files value on IE) and then submit and read the result of the submit.

Something like this which is a code i used before and worked:

var $form = $('your form');//GET YOUR FORM //Create Hidden iframe var _hiddenIframe = $('<iframe id="_hiddenframe" style="display:none;"></iframe>'); //Create Copy Form and add the attributes of the original var _copyForm = $('<form id="_copyForm" name="_copyForm" style="">'); _copyForm.attr({'method':$form.attr('method'),'action':$form.attr('action'), 'enctype':$form.attr('enctype')}); //Get original fields $original = $form.children('*'); //Clone and append to form $original.clone(true).appendTo($form); //send the original fields to hidden form $original.appendTo(_copyForm); //Add the iframe to the body _hiddenIframe.appendTo('body'); //Add the form to the hidden iframe _copyForm.appendTo(_hiddenIframe.contents().find('body')); var $r; //submit the form _copyForm.submit(); //after it reloaded(after post) _hiddenIframe.on('load',function(){ //read result (maybe a json??) $r = $.parseJSON(_hiddenIframe.contents().find('body').text()); //Do something with the result if($r.result=='ok'){ //Do Something if ok } else{ //Do Something if error } });
