我做了一些有用的事。
if (step.backdrop) {
next_step = (iNext != null) && _this.getStep(iNext);
if (!next_step || !next_step.backdrop /*|| next_step.backdropElement !== step.backdropElement*/) {
_this._hideOverlayElement(step);
}
}
所以它结束了:
if (step.backdrop) {
next_step = (iNext != null) && _this.getStep(iNext);
if (!next_step || !next_step.backdrop ) {
_this._hideOverlayElement(step);
}
}
