超级开心，终于搞定了代码
update: function (dt) {
var parent_width = this.node.parent.width;
console.log(parent_width);
this.bg1.x -= this.bg_roll_speed;
this.bg2.x -= this.bg_roll_speed;
console.log(this.bg1.x, this.bg2.x);
if (this.bg1.x <= -parent_width) {
//var bg2_width = this.bg2.x;
this.bg1.x = parent_width ;
}
if (this.bg2.x <= -parent_width) {
// var bg1_width = this.bg1.x;
this.bg2.x = parent_width ;
}
},
