如何在Mozzila上获取fabric.js画布鼠标坐标

问题描述

这是在谷歌浏览器上运行的代码

This is the code that is working on google chrome

var pointer = canvas.getPointer(event.e);
var posiX = pointer.x;
var posiY = pointer.y;
posiX=Math.round( posiX );
posiY=Math.round( posiY );

在mozzila上，我收到"TypeError:事件未定义"，它指向var指针= canvas.getPointer(event.e);

On mozzila i am getting "TypeError: event is undefined" and it is pointing atvar pointer = canvas.getPointer(event.e);

推荐答案

Dime，

请使用如下鼠标事件:

canvas.on('mouse:down', function(event){
   var pointer = canvas.getPointer(event.e);
   var posiX = pointer.x;
   var posiY = pointer.y;
   posiX=Math.round( posiX );
   posiY=Math.round( posiY );
});

必须将

'事件'定义为功能参数的一部分.请确保您具有相同的逻辑.

'event' has to be defined as part of the function parameter. Please make sure you have the same logic.
