插入新的 DOM 元素后航路点设置得太高
Waypoint set too high up after inserting new DOM element
使用Waypoints:在页面上插入新元素(例如错误消息)时,垂直滚动路径点设置得比以前更高。
addWayPoints: function () {
var self = this;
this.$('.table-waypoint').waypoint({
offset: 0,
handler: function (direction) {
self.$hiddenHeadings.toggleClass('visible', direction === 'down');
}
});
this.$('.table-end-waypoint').waypoint({
offset: 165,
handler: function (direction) {
self.$hiddenHeadings.toggleClass('visible', direction === 'up');
}
});
},
我猜当您将元素定义为滚动点时,设置航路点会将其设置为距顶部或底部的像素高度,因此它不是航路点附加到的动态点。
您需要在添加或删除 DOM 元素后重置 waypoints。
addWayPoints: function () {
var self = this;
this.$('.table-waypoint').waypoint({
offset: 0,
handler: function (direction) {
self.$hiddenHeadings.toggleClass('visible', direction === 'down');
}
});
this.$('.table-end-waypoint').waypoint({
offset: 165,
handler: function (direction) {
self.$hiddenHeadings.toggleClass('visible', direction === 'up');
}
});
},
resetWaypoints: function (){
Waypoint.destroyAll();
this.addWayPoints();
},
您可以在切换标题class后调用Waypoint.refreshAll()重新计算所有waypoints的触发点。
