Question

reactjs怎么实现滚动

Answer 1

参考：
scrollState: function(scroll) {
var visibleStart = Math.floor(scroll / this.state.recordHeight);
var visibleEnd = Math.min(visibleStart + this.state.recordsPerBody, this.state.total - 1);

var displayStart = Math.max(0, Math.floor(scroll / this.state.recordHeight) - this.state.recordsPerBody * 1.5);
var displayEnd = Math.min(displayStart + 4 * this.state.recordsPerBody, this.state.total - 1);

this.setState({
visibleStart: visibleStart,
visibleEnd: visibleEnd,
displayStart: displayStart,
displayEnd: displayEnd,
scroll: scroll
});
},
