Syntax Help: If else containing constructor options

DavidColey — Sat, 11 Dec 2021 09:03:41 GMT

So I've bascially got an isMobile var set up to handle various tools that I want to use on the desktop or on mobile and vice versa:

var isMobile = {
  Android: function() {
        return navigator.userAgent.match(/Android/i);
    },
    BlackBerry: function() {
        return navigator.userAgent.match(/BlackBerry/i);
    },
  iOS: function() {
     return navigator.userAgent.match(/iPhone|iPad|iPod/i);
  },
  Opera: function() {
      return navigator.userAgent.match(/Opera Mini/i);
  },
  Windows: function() {
      return navigator.userAgent.match(/IEMobile/i);
  },
  any: function() {
      return (isMobile.Android() || isMobile.BlackBerry() || isMobile.iOS() || isMobile.Opera() || isMobile.Windows());
  }
};

So what I'm trying to do is get the snappingManager to be always on if moble, else set the CTRL key:

var snapManager = mapMain.enableSnapping({

if(!isMobile){[

console.log("im a desktop");

alwaysSnap: true,

tolerance: 5,

snapPointSymbol: snapSym

} else {

snapKey: has("mac") ? keys.META : keys.CTRL,

tolerance: 5,

snapPointSymbol: snapSym

}

});

var layerInfos = [{

layer: lyrParcels

}];

snapManager.setLayerInfos(layerInfos);

Anyway, the syntax isn't quite right setting the snappingManagers' constructor paramters in an if else block. Any help is appreciated.

Forgive the non-js highlighting on this part please - the editor syntax highlighter stopped beahving

Thanks

David,

Since the isMobile is an object and not a boolean value are you sure that it is not always something besides null and thus only entering the first part of the if?

Thanks Robert let me think about that . . .

Ok let's see if I get this right. Since ifMobile is an object, it should never be null unless I am not accounting for a particular OS as part of its properties, I think. That said, I should then be able to flip the script around by invoking(?) snapManager inside of ifMobile thusly:

if (isMobile.any()){
 console.log("Mobile");
     snapManager = mapMain.enableSnapping({
     alwaysSnap: true,
     tolerance: 5,
     snapPointSymbol: snapSym
     });
} else {
     console.log("Not Mobile");
     snapManager = mapMain.enableSnapping({
     tolerance: 5,
     snapPointSymbol: snapSym,
     snapKey: has("mac") ? keys.META : keys.CTRL
});
}

And this seems to work pretty well, but I'll know defineitevely once I push this up so I can test on a mobile platform.

Thanks also to @michael Stranovsky

Thanks for your reply Robert Scheitlin, GISP
