基于HTML模板和JSON数据的JavaScript交互

<textarea id="detail" style="display:none"> <div> <ul> <li>款色号:$ksh$</li> <li>波段$bd$</li> <li>价格:$sp_bj$</li> <li>款式定位:$ks_dw$</li> <li>颜色:$color$</li> </ul> </div> </textarea> <div id="detail1"></div> <script> var data = { "35": 0, "36": 0, "37": 0, "38": 0, "39": 0, "40": 0, "41": 0, "42": 0, "43": 0, "ksh": "17051110154", "bd": "5A", "img": "1_54", "color": "54灰蓝色", "year": "2018", "sum": 10, "L": 2, "M": 2, "XXL": 0, "score": 5, "ks_dw": "普通款", "S": 2, "season": "夏", "kh": "170511101", "order_type": "女装", "XXXL": 0, "color_code": "54", "sp_xl": "上衣", "sp_fl": "上衣", "sp_bj": 539, "ks_dj": "", "count": 10, "yph": 1, "size": "XS,S,M,L,XL", "XL": 2, "sp_id": "23ae0800-181c-4f77-900b-9ab167a94248", "XS": 2 } var htmlList = ''; String.prototype.temp = function(obj) { return this.replace(/\$\w+\$/gi, function(matchs) { var returns = obj[matchs.replace(/\$/g, "")]; console.log(returns); return (returns + "") == "undefined"? "": returns; }); }; var htmls=document.getElementById('detail').value; var bbb= htmls.temp(data); document.getElementById('detail1').innerHTML=bbb; </script>运行

为了将后台的数据处理放到前台，我们可能出现以下的代码

html

    <div class="block m-s-order">
        <div class="block-item block-news">
            <a href="<?php echo site_url('order/detail/'. '$id$')?>"class="dis-block external">
                <div class="item-img"><img src="$thumb$" alt=""/></div>
                <div class="item-intro">
                    <div class="sub-l"><p class="t-order-num">订单号：$order_num$</p>
                        <p class="t-name">收件人：$cus_name$</p>
                        <p class="t-date">$create_time$</p></div>
                        <div class="sub-r">
                            <p class="t-expand">

                        <p class="t-flag">$flag_name$</p></div>
                </div>
                <div class="clear"></div>
            </a>
        </div>
</div> 

 
    <div class="empty-list">
    <div class="icon icon-box"></div>
    <div>还没有订单</div>
</div> 

String.prototype.temp = function(obj) {
return this.replace(/\$\w+\$/gi, function(matchs) {
var returns = obj[matchs.replace(/\$/g, "")];
return (returns + "") == "undefined"? "": returns;
});
};
