Print Templates, Part III: HeaderFooter

Adding Headers and Footers after Rendering

The following lines from onPageComplete() actually add headers and footers to all pages:

myheaderfooter.textHead = printer.header;
myheaderfooter.textFoot = printer.footer;
myheaderfooter.url =
  dialogArguments.__IE_BrowseDocument.URL;
myheaderfooter.title =
  dialogArguments.__IE_BrowseDocument.title;
myheaderfooter.pageTotal =
  document.all.tags("DEVICERECT").length;
for (i = 1; i
  <= myheaderfooter.pageTotal; i++) {
  myheaderfooter.page = i;
  addHeaderAndFooterToPage(i);
}
headersFootersAdded = true;

The HeaderFooter element has an ID of myheaderfooter. The first line of code above sets the textHead property of myheaderfooter. This property includes textual instructions for generating the HTML code of the header. We take these instructions from the TemplatePrinter element (ID=printer):

myheaderfooter.textHead = printer.header;

The TemplatePrinter element stores user's directives regarding the header and footer. Use the Print Setup dialog box to modify the header and footer. We set the footer in a similar way:

myheaderfooter.textFoot = printer.footer;

We set the next two properties, url and title, from the document that is currently displayed. We get a reference to the document object through dialogArguments.__IE_BrowseDocument. URL and title are properties of this object:

myheaderfooter.url =
  dialogArguments.__IE_BrowseDocument.URL;
myheaderfooter.title =
  dialogArguments.__IE_BrowseDocument.title;

We compute the total number of pages by counting the number of DEVICERECT elements:

myheaderfooter.pageTotal =
  document.all.tags("DEVICERECT").length;

We then iterate over all pages. We set HeaderFooter's page property to the current loop index, and call addHeaderAndFooterToPage():

for (i = 1; i <= myheaderfooter.pageTotal; i++) {
  myheaderfooter.page = i;
  addHeaderAndFooterToPage(i);
}
