How to trigger a function using @click inside infowindow of google maps in vue js?

My current code is

addpolygon: function(e) {
      var vm = this;
      var point = {
        lat: parseFloat(e.latLng.lat()),
        lng: parseFloat(e.latLng.lng())
      };
      vm.coord.push(point);
      vm.replot();
      vm.marker = new google.maps.Marker({
        position: point,
        map: vm.map,
        icon: "/fred.png"
      });
      vm.infowindow = new google.maps.InfoWindow({
        content:"<a class=\"btn btn-danger\" @click.native=\"removePoint("+vm.markerid+)\">Remove</a>",
        maxWidth: 300
      });
      vm.bindInfoWindow(vm.marker, vm.map, vm.infowindow);
      vm.markers[vm.markerid] = {
        marker: vm.marker,
        point: point
      };
      vm.markerid++;
    },

When I click on Remove, I need to trigger another function remove Point.

I defined it as

removePoint: function(id) {
      alert("adsf")
    },

But I am not able to trigger the same using the above code. Nothing happens when I click on the button remove. What is the problem regarding the same. Please help me to have a solution?

    New Solution

    Call a global method from InfoWindow using plain-old click handler.

    `onclick="removePoint(${vm.markerId})"`
    

    Then use a closure to access your vm from the global method.

    const vm = this window.removePoint = function(id) { vm.removePoint(id) }

    IF you have multiple instances, you will need to extend this approach.

    Old Solution

    There are 2 issues here.

    First, fix the syntax error concerning the quote.

    vm.markerid + ")\">Remove</a>"

    Even better, take advantage of template strings to avoid this kind of quote insanity.

    vm.infowindow = new google.maps.InfoWindow({ content:`
    <a class="btn btn-danger" @click.native="removePoint(${vm.markerid})">Remove</a>`, maxWidth: 300 });
    

    Second, any function inside a vue template is always within the scope of the component. Assume a this. object is placed in front. So calling removePoint is really calling this.removePoint.

    Define function inside instance.

    vm.removePoint = function(id) { console.log(`removing point ${id}...`) }

    Or make sure your component options defines removePoint in the methods section.

    You can also define removePoint globally (on the window object) and call $window.removePoint(" + vm.markerId + ")" from the template if using a plugin such as https://www.npmjs.com/package/window-plugin.

    @click.native=\"$window.removePoint(" + vm.markerid ...

    function removePoint(id) { console.log(`removing point ${id}...`) }
