DREAMWEAVER CS3 153 Extending Dreamweaver The getDynamicContent() function calls the dw.getBrowserList() function to obtain an array of the browser names that have been specified in the Preview In Browser section of the Preferences dialog box. This array contains the name of each browser and the path to the executable file. Next, for each item in the array (i=0; i 0); } The canAcceptCommand() function in the PIB_Dynamic.js file again retrieves the browser list that was created in the Preferences dialog box. Then it checks whether the first argument (arguments[0]) is primary or secondary. If so, it returns the value returned by the havePreviewTarget() function. If not, it tests the call to the havePreviewTarget() function and tests whether any browsers have been specified (PIB.length > 0). If both tests are true, the function returns the value true. If either or both of the tests are false, the function returns the value false. havePreviewTarget() The havePreviewTarget() function is a user-defined function that returns the value true if Dreamweaver has a valid target to display in the browser. A valid target is a document or a selected group of files in the Site panel. The havePreviewTarget() function looks like the following example: function havePreviewTarget() { var bHavePreviewTarget = false; if (dw.getFocus(true) == 'site') { if (site.getFocus() == 'remote') { bHavePreviewTarget = site.getRemoteSelection().length > 0 && site.canBrowseDocument(); }
