Resolved Minimum and Maximum Zoom Level for GMaps

I think there is no option to set the minimum and maximum level for the gmaps module.

The idea behind this is not to display the exact location of members but rather give a broad indication of where they are (for instance 120 member grouped in one city).

Hi,
this is not possible, user map module set zoom (and center) automatically based on all displayed markers.

Yes, I know, but now this is not possible in our module. To do this you need to override module output and put your custom code. But this is not so simple.

do you think this could be a good feature for a future release?
I believe that in many use cases this could be beneficial.

Hi,
we think this can create some issue, zoom require also to set center of map and this is not user friendly. Also it can make some problems also Group result option.

To do this follow these steps:
- Copy file from /modules/mod_jsnmap/tmpl/default.php to /templates/your-template-folder/html/mod_jsnmap/default.php
- Edit new file, add following code at line 143 (replace 11 with your zoom)


google.maps.event.addListenerOnce(jsnmap<?php echo $module->id; ?>, 'idle', function() {

        jsnmap<?php echo $module->id; ?>.setZoom(11); 

});


You can also change name from default.php to somethingelse.php and set this new layout in the "Alternative Layout" parameter in Module Advanced options (see screenshot).

BTW does this set the standard zoom, so the whole map will be at zoom 11 at all time?

I was looking for a solution where the user can zoom in and out as much as he wants unless he reaches the maxiumum zoom level of for instance 11...

Hi,
replace previous code with something like this:


google.maps.event.addListenerOnce(jsnmap<?php echo $module->id; ?>, 'zoom_changed', function() {

        if(jsnmap<?php echo $module->id; ?>.getZoom()>11 )

          jsnmap<?php echo $module->id; ?>.setZoom(11); 

    });
