Binded click loses context of my Class. JS
- by Fabiano PS
Hi, I have this problem that I probably understand but don't know how to handle, if there is a way.
I have a class simplified as this:
function DrawingTable(canvas_id){
this.canvas_id = canvas_id;
bind_events()
function bind_events(){
$(get_canvas()).click(function(e){
var canvas = get_canvas() //works
do_something_in_the_instance_who_called_click()
}
function get_canvas(){return document.getElementById(canvas_id)}
function do_something_in_the_instance_who_called_click(){
alert(this.canvas_id) //fail!
}
}
Because when the click() is invoked for what it looks this is not inside the instance anymore, but I need to change atributes from there.. is there a way, given that may be multiple instances?
I don't really know how but the get_canvas() works :)
I'm using jQuery but likely not relevant
