小程序开发时有个联动的标签选择（如图）例如：第一次选择了（["麻辣拌（无汤带麻酱）", "酸甜麻辣拌（无麻酱）"]）两个属性后，如果取消了其中一个属性，那根据我的条件判断，应该是替换相应的值，而不是新增。现在出现的问题是，每次根据type类型查找下标，每次都是-1。代码：checkAttribute: function (e) { let pre = 0; let obj = {}; let tempArr = this.pureData.tempArr; const values = e.detail.value; console.log("values(1386) => ", values); const types = this.data.curAttributesType; const curAttributes = this.data.curAttributes; curAttributes.forEach(item => { const isExist = values.some(cur => cur === item.name) if (isExist) { item.checked = true; } else { item.checked = false; } }); const myAtr = curAttributes.filter(item => item.checked === true); obj.type = types; obj.value = myAtr; if (this.pureData.tempArr.length > 0) { const typeIdx = tempArr.findIndex(item => { item.type === this.data.curAttributesType }); console.log("typeIdx(1404) => ", typeIdx); if (typeIdx != -1) { this.pureData.tempArr[`${typeIdx}`].value = myAtr; } else { this.pureData.tempArr.push(obj) } } else { this.pureData.tempArr.push(obj); } console.log("tempArr(1412) => ", this.pureData.tempArr); this.setData({ curAttributes: curAttributes, }); },
