splice删除数组的时候出现BUG，逻辑层和视图层不同步。There is a bug when splice deletes the array, and the logic layer and the view layer are out of sync.

delArr(options){  var index = options.currentTarget.dataset.index;  var step = this.data.step;  step.splice(index,1);  this.setData({step:step});}

Framework type problem type terminal type wechat version basic library version applet bug wechat Android client 8.0.20 2.23.3 after deleting the array, the logical layer has been executed, but the view layer has not been rendered. delArr(options){ var index = options.currentTarget.dataset.index;  var step = this.data.step;  step.splice(index,1);  this.setData({step:step});}
