I am getting a Blob content from webservice callout and requirement is to display the file in browser.
What I have:
Above blob parameter I get as response and sending same back to javascript method in "callback". I am trying to convert the blob to respective file format and view on browser (I dont want to download unless enduser wants so).
I tried below:
var callback1 = {
onSuccess: function(e){ //e is the blob content I am receiving
alert('Receiving file from SF:---> ' + e);
var file = new File([e], "uploaded_file.pdf", { type: "application/pdf", lastModified: Date.now() });
//document.body.append(file);
//var blob=new Blob([e], {type:"application/pdf"});
var link=document.createElement('a');
//link.href=window.URL.createObjectURL(e);
link.download=file;
link.click();
}, onFailure: function(error){
alert(error);
}
};
Update
Update 2 (after treating response as base64)
Make use of iframe to display pdf file, the function would look like this with blob response and file name.
function openPDF(resData, fileName) {
var ieEDGE = navigator.userAgent.match(/Edge/g);
var ie = navigator.userAgent.match(/.NET/g); // IE 11+
var oldIE = navigator.userAgent.match(/MSIE/g);
var bytes = new Uint8Array(resData); //use this if data is raw bytes else directly pass resData
var blob = new window.Blob([bytes], { type: 'application/pdf' });
if (ie || oldIE || ieEDGE) {
window.navigator.msSaveBlob(blob, fileName);
}
else {
var fileURL = URL.createObjectURL(blob);
var win = window.open();
win.document.write('<iframe src="' + fileURL + '" frameborder="0" style="border:0; top:0px; left:0px; bottom:0px; right:0px; width:100%; height:100%;" allowfullscreen></iframe>')
}
}
