问题
I have a simple web page where 1 frame displays a pdf and another a menu bar.
<iframe src="bar.html" name="menu" ></iframe>
<iframe src="doc.pdf" name="itempane" ></iframe>
Using chrome I can navigate from the menu bar to the parent and back down to the frame containing the pdf in order to print it
var pWindow = window.parent;
pWindow['itempane'].print();
Attempting to do the same in IE11 gives an Invalid calling object error.
you can see this at http://www.abhrdev.co.uk/main.html
What am I doing wrong / what is IE doing differently?
Cheers
Updated.....
I think I have proved that this is not a javascript coding issue but related to the pdf handling in IE. With the following page
<a href="javascript:printFromMain('pdfpane');">Print PDF</a><br/>
<a href="javascript:printFromMain('htmlpane');">Print HTML</a>
<iframe src="bar_1.html" name="menu" ></iframe>
<iframe src="doc.pdf" name="pdfpane" ></iframe>
<iframe src="doc.html" name="htmlpane" ></iframe>
and this function
function printFromMain(paneName) {
var pWindow = window[paneName];
pWindow.focus();
pWindow.print();
}
the printing of the html page works but not the pdf the pWindow.focus() gives Invalid Calling Object - any insight into why that might be greatfully recieved
回答1:
After trying several things, I finally go this to work in IE11:
1) use an object tag instead of iframe
2) run focus() / print() directly on the element
3) run after a timeout, to make sure everything in is loaded. There may be a better way (like using some event listener) to do this, as the timeout time needs to be fairly long for it to work properly
setTimeout(function () {
var contentThingy = document.getElementById('itempane');
contentThingy.focus();
contentThingy.print();
}, 4000);
Object (with a specified id) instead of iframe:
<object id="itempane" ... ></object>
Note: doesn't work in chrome. One of the other variations in the other answers (i.e. using ContentWindow) may.
回答2:
Try actually using the window.frames to get the frameList and reference it by the frame name that way.
var pWindow = window.parent; //reference the parent from the iframe
var ifr = pWindow.frames.itempane; //get the pdf frame from the frame list
ifr.focus();
ifr.print();

Try this
<iframe src="bar.html" name="menu" ></iframe>
<iframe src="doc.pdf" ID="itempane" ></iframe>
var otherPane = parent.document.getElementById("itempane");
otherPane.focus(); // OR
otherPane.print(); // OR
var doc = otherPane.contentWindow || otherPane.contentDocument;
doc.focus();
doc.print();
