Subject: [xsl] Pop-up window From: Jenny Simpson <simpson@xxxxxxxxxxx> Date: Fri, 31 Aug 2001 16:53:32 -0600 |
Hi all, My problem is fairly straight-forward. I have a bibliography database in xml that is displayed as a list of publications using xsl. "Abstract" is one of the fields contained in each entry. Here is a sample entry: <bibitem type="inproceedings"> <author URL="http://www.cs.utah.edu/~whitaker/">R. Whitaker</author> <booktitle>Fifth International Conference on Computer Vision '95</booktitle> <keywords>Deformable Models</keywords> <month>June</month> <note>(full paper, peer review)</note> <pages>822--827</pages> <title>Algorithms for implicit deformable models</title> <year>1995</year> <abstract><p>This paper presents a framework for implicit deformable models and a pair of new algorithms for solving the nonlinear partial differential equations that result from this framework. Implicit models offer a useful alternative to parametric models, particularly when dealing with the deformation of higher-dimensional objects. The basic expressions for the evolution of implicit models are relatively straightforward; they follow as a direct consequence of the chain rule for differentiation. More challenging, however, is the development of algorithms that are stable and efficient. <p>The first algorithm is a viscosity approximation which gives solutions over a dense set in the range, providing a means of calculating the solutions of embedded families of contours simultaneously. The second algorithm incorporates sparse solutions for a discrete set of contours. This sparse-field method requires a fraction of the computation compared to the first but offers solutions only for a finite number of contours. Results from 3d medical data as well as video images are shown. </abstract> </bibitem> I have the abstract displayed as a link and I want the user to be able to click on the abstract for any publication and see a pop-up window containing the abstract and other related information. The problem with using a regular javasript pop-up window is that I don't want to refer to a different URL; I want to display the current values in the current node and I would lose that information if I referred to a new URL. The option that seems best is the pass the current element values as parameters to a javascript function, then build the content for the pop-up window in the javascript itself. The javascript looks like this: function subWrite(thisAbstract, author, month, year, title, journal, editor, volume, number, pages, publisher){ makeNewWindow(); newWindow.focus(); var newContent = "<html><head><title>Abstract</title></head>"; newContent += "<body><h1>Abstract</h1>"; newContent += thisAbstract; newContent += "</body></html>"; newWindow.document.write(newContent); newWindow.document.close(); } The function call in the xsl looks like this: <a href="javascript:subWrite('{$thisAbstract}', '{$author}', '{$month}', '{$year}', '{$title}', '{$journal}', '{$editor}', '{$volume}', '{$number}', '{$pages}', '{$publisher}')">Abstract</a> This works fine as long as there are no single or double quotes in the variables being passes as parameters. In other words, if the abstract contains a quotation mark somewhere (and many do), the xsl interprets the quote as if it is the end of the function call instead of just ignoring it as part of the text. Is there a way to pass xsl element values (values which change depending on context) to a javascript function without having the xsl try to parse the values in the process? Also, is there a better way to create a pop-up window to display values from current nodes in xsl? I hope this made sense. Thanks in advance.
