I have a VueJS component which is a svg map image of the united states. I previously used jquery to create hover effects to display the information bubble. I am trying to convert this to a pure Javascript solution. It seems a click event is the easiest to implement given vuejs mousemove seems to be less reliable. I have added the click event in method and I am trying to capture the SVG path location and steal the top and left position to enable the info box there. I have tried this.offsettop and this.offsetleft but they return undefined.
Jquery code I am trying to convert:
$("path, circle").hover(function(e) {
$('#info-box').css('display','block');
$('#info-box').html($(this).data('info'));
});
$("path, circle").mouseleave(function(e) {
$('#info-box').css('display','none');
});
$(document).mousemove(function(e) {
$('#info-box').css('top',e.pageY-$('#info-box').height()-30);
$('#info-box').css('left',e.pageX-($('#info-box').width())/2);
}).mouseover();
var ios = /iPad|iPhone|iPod/.test(navigator.userAgent) && !window.MSStream;
if(ios) {
$('a').on('click touchend', function() {
var link = $(this).attr('href');
window.open(link,'_blank');
return false;
});
}

The solution was found in the comments on the question.
In summary, the issue was understanding how to position the #info-box element. Using the getBoundingClientRect() function, we can get the position of any element relative to the entire document. To get the position of the clicked path element, simply subtract the top and left of the #us-map from the top and left of the path. This will give the position for the top left corner of the path, relative to the containing element. We can then use that to position the #info-box.
Here is my code:

Basically I want the rotation of the container div to vary accordingly to the var vento_direzione (which it is a number obtained from the api request to witch I have appended a "deg" string) whenever I click the button; sadly, that doesn't seem to happen. If I just pass a value inside the function instead of the var, everything works fine. What am I doing wrong?
Please help! Cheers!
you want
document.getElementById("container").style.webkitTransform = "rotate("+vento_direzione+")";
As it is you are just trying to pass it the literal string "rotate(vento_direzione)", variables do not get replaced with their values when they are in strings like that.
So what you need to do is concatenate the actual string parts "rotate(" and ")" with the vento_direzione variable: "rotate("+vento_direzione+")" is string concatenation
