selectedGoods = {}; //默认选择的商品
let selectOptionValue = [],
selectOption = []; //默认选中的属性
let isInvalid = false;
let filterList = _self.data.goodsList.filter(function(fItem, fIndex) {
return fItem.CommodityID == commodityID;
}); //当前商品的ID是默认选择的商品ID
if (filterList.length > 0) {
selectedGoods = filterList[0];
if (_self.data.natureOptions) {
_self.data.natureOptions.forEach(function(nature, natureindex) {
nature.forEach(function(option, optionIndex) {
if (option.Selected) {
selectOptionValue.push(option.OptionValue);
selectOption.push(option.NatureOptionID);
}
})
})
}
}
//判断是否已售罄
if (selectedGoods.StockAmount > 0 && selectedGoods.IsUpShelf) {
isInvalid = false
} else {
isInvalid = true
}
_self.setData({
selectedGoods: selectedGoods,
selectOption: selectOption,
selectOptionValue: selectOptionValue,
isInvalid: isInvalid,
goodNum: 1
});
3.选择属性，不能选择的置灰： selectGuige: function(e) { // 定义变量 start let natureIndex = e.currentTarget.dataset.natrueindex, //此时点击的属性索引 selectOptionValue = this.data.selectOptionValue, //已选择的商品属性值 selectOption = this.data.selectOption, //已选择的商品属性 optionID = e.currentTarget.dataset.id, //此时被点击的属性规格值 optionIndex = e.currentTarget.dataset.opindex, //此时被点击的属性规格值索引 preSelectGoodsList = [], //可能会被选中的商品 natureOptions = this.data.natureOptions, //所有规格属性 goodsList = this.data.goodsList, //商品列表 disableList = [], //不可选值 selectedGoods = {}, //选中的商品 isInvalid = this.data.isInvalid //按钮是否可用 ; // 定义变量 end //有此规格属性值的商品列表 preSelectGoodsList = goodsList.filter(function(fItem, fIndex) { return fItem.NatureDetails.indexOf('_' + optionID + '_') > -1; }) natureOptions[natureIndex].forEach(function(options) { if (options.NatureOptionID == optionID) { //属性值==当前选中的属性 options.Selected = 1; //修改选中状态 selectOptionValue.splice(natureIndex, 1, options.OptionValue); //记录选中的属性值 selectOption.splice(natureIndex, 1, options.NatureOptionID); //记录选中的属性 } else { options.Selected = 0; //修改选中状态 } }) var temp = []; natureOptions.forEach(function(nature, nIndex) { if (natureIndex != nIndex) temp.push(nature) }) natureOptions.forEach(function (nature, naIndex) { let isBreak = false; for (let opIndex = 0; opIndex < nature.length; opIndex++) { let options = nature[opIndex]; if (naIndex != natureIndex) { //父级ID值！=当前选择的父级 disableList = preSelectGoodsList.filter(function (fItem) { return fItem.NatureDetails.indexOf('_' + options.NatureOptionID + '_') == -1; }) //当前属性不在预选商品中，则为disabeld if (disableList.length == preSelectGoodsList.length) { options.Disabled = true; if (options.Selected == 1) { selectOptionValue.splice(naIndex, 1, ''); selectOption.splice(naIndex, 1, 0); } options.Selected = 0; } else { options.Disabled = false; } } } let selectNature = nature.filter(function (fItem) { return fItem.Selected == 1 }); if (selectNature.length > 0) { if (nature[0].NatureID != temp[temp.length - 1][0].NatureID) { preSelectGoodsList = preSelectGoodsList.filter(function (fItem, fIndex) { return fItem.NatureDetails.indexOf('_' + selectNature[0].NatureOptionID + '_') > -1; }) } } }) //当匹配到的规格可以选中唯一商品时，给选中商品赋值 for (let i = 0; i < selectOption.length; i++) { if (selectOption[i] != 0) { goodsList = goodsList.filter(function(fItem) { return fItem.NatureDetails.indexOf("_" + selectOption[i] + "_") > -1; }) if (goodsList.length == 1) { break; } } } if (goodsList.length == 1) { selectedGoods = goodsList[0] //判断库存是否大于0 if (selectedGoods.StockAmount > 0) isInvalid = false; else isInvalid = true; this.setData({ selectedGoods: selectedGoods }) } else { isInvalid = true; } console.log(selectedGoods) this.setData({ natureOptions: natureOptions, selectOption: selectOption, selectOptionValue: selectOptionValue, isInvalid: isInvalid }) } 备注：可能会有BUG，用作记录
