start a function when click on circle - leaflet

rated 0 times [ 105] [ 4] / answers: 1 / hits: 7732 / 8 Years ago, sat, march 5, 2016, 12:00:00

I make some circles in JS as follow:

L.circle(

  [46.765735535841024, 23.58344078063965], 5, {

    color: blue

  }).addTo(map).bindPopup(Description: This is my description);

I want to replace that bindPopup with a function. When I click the circle, instead of my description display, I want to run a function, for example I made this function:

function circleClick() {

     // my implementations;

}

Would someone tell me how could I do this possible?

Simply assign your circleClick function as listener on each of your circles:

L.circle(

  [46.765735535841024, 23.58344078063965], 5, {

    color: blue

  }

).addTo(map).on(click, circleClick);

// more L.circle's...



function circleClick(e) {

    var clickedCircle = e.target;



  // do something, like:

  clickedCircle.bindPopup(some content).openPopup();

}

Alternatively, you can gather all your circles within a Feature Group, and attach the event listener to that group only:

var group = L.featureGroup().addTo(map);



L.circle(

  [46.765735535841024, 23.58344078063965], 5, {

    color: blue

  }

).addTo(group);

// more L.circle's...



group.on(click, function (e) {

    var clickedCircle = e.layer; // e.target is the group itself.



  // do something, like:

  clickedCircle.bindPopup(some content).openPopup();

});
