基於ecshop的移動端 etouch實現動態獲取分類商品列表
阿新 • • 發佈：2019-02-17
修改檔案 category.php
關鍵兩個地方需要修改
if ($_GET['act'] == 'asynclist') {
$sayList = array();
if (is_array($goodslist)) {
foreach ($goodslist as $vo) {
$shop_price = empty($vo['promote_price']) ? $vo['shop_price']:$vo['promote_price'];
$watermark_img 還有一個叫做 category_get_goods 這個函式此函式新增了一個欄位 collect返回欄位可以用於前端頁面檢視渲染的時候實現判斷是否已經蒐藏 並且根據是否蒐藏顯示不同的樣式和繫結不同的事件函式

}
//這裡加入成功
//注意這裡引入了一個自己寫的基於zepto移動端函式庫的一個外掛 請參考我以前寫的一篇文章裡面有這個外掛的程式碼
Zepto('body').popup({
title:'提示資訊'
,id:'alert'
,closeOnOk:true
,ok:'確定',
message:result.message
});
}總結
以前非常喜歡php 弄過一段時間 所以php程式碼也是基本上都能夠看懂 mysql 也學過
沒有php 基礎的童鞋可以先去學學php基礎
現在博主努力專研前端 後端也在學習 最近學習javascript 和 html5的新api 這些
