AJAX 从伺服驱动器获得JSON列阵 串连在HTML里 想要知道为何麽我的each循坏只能抓数据库索引数值1的json列阵放进去??

这也是教师的案例 我还是看不出来区别在哪儿求得

success: function(data){ // request 取得成功获得回复後实行 console.log(data); let list_html = ''; $.each(data, function(index, item){ list_html = '<li data-id="' item.item_id '" data-star="' item.star '" data-sort="' item.sort '">'; list_html = '<div class="item_flex">'; list_html = '<div class="left_block">'; list_html = '<div class="btn_flex">'; list_html = '<button type="button" class="btn_up">往上面</button>'; list_html = '<button type="button" class="btn_down">向下</button>'; list_html = '</div>'; list_html = '</div>'; list_html = '<div class="middle_block">'; list_html = '<div class="star_block">'; list_html = '<span class="star' (item.star >= 1 ? " -on" : "") '" data-star="1"><i class="fas fa-star"></i></span>'; list_html = '<span class="star' (item.star >= 2 ? " -on" : "") '" data-star="2"><i class="fas fa-star"></i></span>'; list_html = '<span class="star' (item.star >= 3 ? " -on" : "") '" data-star="3"><i class="fas fa-star"></i></span>'; list_html = '<span class="star' (item.star >= 4 ?

这也是json获得的內容 为一个列阵
