Question

Passing Parameters with loadMovie

Asked by: craigbtg

Hello,

I have a dynamically generated menu (thanks to the help of cyanblue) that loads a movie clip once the user clicks on a menu item.  I am looking to extend this menu so that I can pass parameters to the movie clip.  My menu gets created as follows:

var cReturn = "\r";
var lFeed = "\n";
_root.contentMC.portmenuMC._visible = false;
y_port_start = 30;

var projectstext = new LoadVars();
projectstext.onLoad = function() {
      var pData = projectstext.academicProjects.split(lFeed);
      for (i=0; i<pData.length; i++) {
            makeButton(i, pData[i]);
      }
}
projectstext.load("academic.txt");

function makeButton(buttonNum, projLabel) {
      _root.contentMC.portmenuMC.duplicateMovieClip("portmenuMC"+buttonNum, buttonNum);
      _root.contentMC["portmenuMC"+buttonNum].port_name.text = projLabel;
      _root.contentMC["portmenuMC"+buttonNum].backMC._width = _root.contentMC["portmenuMC"+buttonNum].port_name._width;
      _root.contentMC["portmenuMC"+buttonNum]._y = y_port_start + (_root.contentMC["portmenuMC"+buttonNum]._height * (buttonNum));    
      _root.contentMC["portmenuMC"+buttonNum].choice = buttonNum;
      _root.contentMC["portmenuMC"+buttonNum].id = "project_page.swf";
     _root.contentMC["portmenuMC"+buttonNum].onPress = function ()
     {
             _root.loadMovie(this.id);
          gotoAndPlay(this.id);
     }
      levelTrack = buttonNum;
}


I have tried changing "project_page.swf" to "project_page.swf?projectid=xxx" but this throws an error when the movie clip tries to load.  Can someone please try and help me with the syntax?

Once I can pass the parameter the movie clip will use it to load different details based on which menu item was clicked.  Thanks.

Does the project_page.swf file contain a mechanism to accept the projectid variable and do whatever is necessary???  Or do you have to build such function???  Do you have an access to the project_page.fla file???

Yes, the project_page pulls info from an ASP page which will take the projectid parameter and use it to query the database.  I have the project_page working correctly by itself.  My problem is I can't seem to get the movie to load.  It keeps throwing an error when I add in the parameter.  I have access to all pages.  Thanks.

Well...  It sounds like it is abit more complicated and it could create a conflict on the variable...

Here is what I'd do...

In the frame 1 of the project_page.fla file, I'll add this action...

     if (_global.projectid.length > 1)
     {
          gotoAndPlay(_global.projectid);
     }

and in the main file, I'd change that onPress handler like this...

     _root.contentMC["portmenuMC"+buttonNum].onPress = function ()
     {
          _global.projectid = "xxx"; // or whatever value you want to trigger the action...
          _root.loadMovie(this.id);
     }

See if you can use that sort of logic...  ;)

project_page.swf?projectid=xxx should only cause loading to fail when you run the project locally. It should work fine served from a web server.

Thanks cyanblue.  Your suggestion worked great!
