使用javascript从iframe打印pdf

Question

While running time I'm adding pdf in iframe dynamically and printing that iframe.

But it's showing Permission denied error

This is my code

    g_iFrame = document.createElement("iframe");
    g_iFrame.id = "testFrame";
    var style = g_iFrame.style;
    style.border = "1px solid black";
    style.width = "300px";
    style.height = "200px";
    g_iFrame.src = "D:\\Testing\\PDF\\"+mYFileList[i][0];

    document.body.appendChild(g_iFrame);
    var iframe = document.getElementById('testFrame');
    var frm = iframe.contentWindow;
    frm.focus();
    frm.print();

Note : mYFileList[i][0] is my pdf file from array

In Firefox you face this ? See this

I have built a way around, not perfect yet. Need to effectively use window.postMessage ( this can be helpful ) to confirm pdf loaded, before printing.

$(document).ready(function(){
g_iframe = document.createElement("iframe");
g_iframe.id = "testFrame";
var style = g_iframe.style;
style.padding = "0px";
g_iframe.width = "960px";
style.height = "1100px";
g_iframe.src = "D:\\Testing\\PDF\\"+mYFileList[i][0];


g_iframe.addEventListener('load', function(){

    setTimeout(function(){
        $("iframe[id='testFrame']").html('<script type="text/javascript"> window.print(); </script>');
    }, 2000); 
}, true);

document.body.appendChild(g_iframe);

});
