两个bug about larea

//重置节点个数
setGearTooth: function(data) {
var _self = this;
var item = data || [];
var l = item.length;
if (_self.gearArea==null) { return false;}
var gearChild = _self.gearArea.querySelectorAll(".gear");
var gearVal = gearChild[_self.index].getAttribute('val');
var maxVal = l - 1;
if (gearVal > maxVal) {
gearVal = maxVal;
}
gearChild[_self.index].setAttribute('data-len', l);
if (l > 0) {
var id = item[gearVal][this.keys['id']];
var childData;
switch (_self.type) {
case 1:
childData = item[gearVal].child
break;
case 2:
var nextData= _self.data[_self.index+1]
for (var i in nextData) {
if(i==id){
childData = nextData[i];
break;
}
};
break;
}
var itemStr = "";
for (var i = 0; i < l; i++) {
itemStr += "<div class='tooth' ref='" + item[i][this.keys['id']] + "'>" + item[i][this.keys['name']] + "";
}
gearChild[_self.index].innerHTML = itemStr;
gearChild[_self.index].style["-webkit-transform"] = 'translate3d(0,' + (-gearVal * 2) + 'em,0)';
gearChild[_self.index].setAttribute('top', -gearVal * 2 + 'em');
gearChild[_self.index].setAttribute('val', gearVal);
_self.index++;
if (_self.index > 2) {
_self.index = 0;
return;
}
_self.setGearTooth(childData);
} else {
gearChild[_self.index].innerHTML = "

";
gearChild[_self.index].setAttribute('val', 0);
if(_self.index==1){
gearChild[2].innerHTML = "

";
gearChild[2].setAttribute('val', 0);
}
_self.index = 0;
}
}
加入这行代码可以解决 滚动没有结束就点击取消报错 if (_self.gearArea==null) { return false;}

function gearTouchEnd(e) {
e.preventDefault();
var target = e.target;
while (true) {
if (!target.classList.contains("gear")) {
target = target.parentElement;
} else {
break;
}
}
var flag = (target["new_" + target.id] - target["old_" + target.id]) / (target["n_t_" + target.id] - target["o_t_" + target.id]);
flag = isNaN(flag) ? 0.001 : flag;
if (Math.abs(flag) <= 0.2) {
target["spd_" + target.id] = (flag < 0 ? -0.08 : 0.08);
} else {
if (Math.abs(flag) <= 0.5) {
target["spd_" + target.id] = (flag < 0 ? -0.16 : 0.16);
} else {
target["spd_" + target.id] = flag / 2;
}
}
if (!target["pos_" + target.id]) {
target["pos_" + target.id] = 0;
}
rollGear(target);
}
加入这行语句可以解决点击元素报错flag = isNaN(flag) ? 0.001 : flag;

[wangquanjava]

在170行添加上这个判断就能解决点击报错
if(isNaN(flag)){
return ;
}

2.1 close作如下修改
close: function(e) {
e.preventDefault();
var _self = this;
var evt = new CustomEvent('input');
_self.trigger.dispatchEvent(evt);
// document.body.removeChild(_self.gearArea);
// _self.gearArea=null;
_self.gearArea.style.display="none";
}
2.2 popupArea加如下内容
function popupArea(e) {
if(_self.gearArea) {
_self.gearArea.style.display="block";
return;
}
.....原来的代码
}
解决滑动未结束持续报错问题，也避免每次都创建dom节点
