-JavaScript Diagram Builder - Browser support- |
| -The JavaScript Diagram Builder works with Microsoft Internet Explorer 4.x, Netscape 4.x, Netscape 6.x and Opera 5.x -under Windows and with Netscape 6.x, Opera 5.x and Konqueror 3.x under Linux. Most of the methods, which dynamically change -the properties of the objects, will only work correctly with IE 5, Netscape 6, Opera 7 and Konqueror 3 or higher. -Here you can test the methods for the single objects. - |

-Because of a bug in Netscape 4.x (N4) you should add the following code in the web page -before using the diagram objects: -<DIV STYLE="position:absolute; top:0px"></DIV> -Also for N4 the file transparent.gif must be in the directory of the web page. -Furthermore, N4 has trouble when opening a page with a diagram in a new window, because the extern script will not be -included. In order to work around this bug, you must reload the page, it also can be done automatically with -<SCRIPT Language="JavaScript">if ((document.layers)&&(history.length==1)) location.href=location.href+"#";</SCRIPT> -which must be written in the head before including the extern script. -Tooltiptext will not work at all with N4. Click on a Bar or Box works only with N4, if you click on the text. - -In order to print all objects correctly, you must specify in your browser settings to print also the background. -For instance in Internet Explorer, use the menu View->Internet Options->Advanced and enable "Print backgrounds colors and images". - -Since version 2.8 the formerly script file diagram.js is splitted into the 3 files diagram.js (13 kB - browser independent code), -diagram_nav.js (98 kb - code for Netscape 4) and diagram_dom.js (89 kB - code for browsers which are DOM conform). -In this way the total file size for the download decreases, because the new file diagram.js automatically loads - depending on the detected browser -- only one of the files diagram_nav.js or diagram_dom.js. This makes also the execution of the script a bit faster, because -browser dependent overhead within the methods of the objects is no longer required. -If you do not use Line, Area, Arrow or Pie objects, then you can significantly reduce the file size by deleting the appropriate code from the script file. -If the script files diagram*.js are not in the same directory as the html page which uses the script, then you must edit -the file diagram.js and set the correct relative or absolute path in the variable _PathToScript. - -The last remark is about names of variables, functions and IDs: The Diagram Builder uses some global variables and functions, -all of them start with the letter "_" (for instance "_Draw()"). In order to prevent bugs caused by duplicate names of -variables or functions, you should not use names which begin with the letter "_" in your script. Additionally, there are -IDs for the objects, which start with "Dia", "Bar", "Box", "Dot", "Pix", "Line", "Area", "Arrow" or "Pie". Don't use ID's in your HTML page, -which start with this letters (for instance don't use <div id='Dia1'>...</div>). - |
