微信小程序中遇到的多規格問題(一)
剛進入公司的時候就有遇到過多規格的問題，當時就以爲很麻煩，就只是看了下，沒有嘗試，最近在寫微信小程序的時候，又遇到了多規格問題，就本身嘗試了下，在這裏記錄下
1.效果圖

3.部分思路及改進方法
開始想到的是將需合併的id的位置寫死，好比，第一個位置就傳第一個規格里選中的規格id，第二個位置就傳第二個規格里選中的規格id,不過此時有問題，就是後臺的id拼接是根據當前規格長度來拼接的，從最短的開始往長的拼接，而後，長度相等的時候，我這邊的話，後臺是從第一個開始拼接的，並且你選規格時，也多是隨機點的，此時如果採用第一種位置寫死的方法就會有問題，由於會找不到對應的合併後的規格id
- 由於我這裏一開始用的數據就恰好知足個人設想，可是後面換了個數據後就出現問題了
- index.wxml文件也作部分修改,能夠直接查找下，類名爲standardItem
<view class="standardItem">
<block wx:for="{{item}}" wx:key="{{item.item_id}}">
<view class="selectItem {{item.item_id == Specifications[standardIndex]?'standardSelected':'standardNormal'}}" bindtap="handleStandardClick" data-standard-index="{{standardIndex}}" data-name="{{item.item}}" data-id="{{item.item_id}}">{{item.item}}</view>
</block>
</view>

}
}

checkSpecifications(spec_goods) {
let spec_goods_price = spec_goods || this.data.spec_goods_price;
let Specifications = this.data.Specifications;
let SpecificationsLength = spec_goods_price[0].key.split("_").length;
let standardObject = this.data.standardObject;
if (Specifications.length != SpecificationsLength) {
return false;
} else {
for (let i = 0; i < spec_goods_price.length; i++) {
/* 若selectSpecifications全爲true，則選中了對應的合併後的規格 */
let selectSpecifications = true;
for (let j = 0; j < Specifications.length; j++) {
if (spec_goods_price[i].key.indexOf(Specifications[j]) == -1) {
selectSpecifications = false;
break;
}
}
if (selectSpecifications) {
standardObject.price = spec_goods_price[i].price;
standardObject.store_count = spec_goods_price[i].store_count;
this.setData({
standardObject,
})
return spec_goods_price[i].id;
}
}
}
return false;
},
- 利用indexOf來判斷合併後的key值，就不用經過寫死位置存儲規格，而後這裏用了動畫，能夠本身查看官方完檔微信建立動畫
這裏的規格啥的，格式可能會是多樣的，我這裏的話，就是返回這樣的格式，其實我還想實現就是根據庫存來判斷是否能夠點擊，好比選尺碼28，而後可能顏色爲黑色的就庫存不足，此時，是不能讓他點擊的，往後會在作下這個功能，歡迎你們在評論區指正，共同進步^_^
