ECSHOP 商品详情页购买数量 添加加减按钮 实用版

打开模板文件goods.dws 查找代码

<input name="number" type="text" id="number" value="1" size="4" onblur="changePrice()" style="border:1px solid #ccc; "/>

修改为

<span class="goods_cut" onclick="goods_cut();changePrice();"><img src="images/plus1.gif" alt="减少" width="15" height="15" /></span>
<input name="number" type="text" id="number" value="1" size="4" onblur="changePrice()" style="border:1px solid #ccc; "/>
<span class="goods_add" onclick="goods_add();changePrice();"><img src="images/plus2.gif" alt="增加" width="15" height="15" /></span>

 

再添加js脚本

<script language="javascript" type="text/javascript">function goods_cut(){var num_val=document.getElementById('number');var new_num=num_val.value;var Num = parseInt(new_num);if(Num>1)Num=Num-1;num_val.value=Num;}function goods_add(){var num_val=document.getElementById('number');var new_num=num_val.value;var Num = parseInt(new_num);Num=Num+1;num_val.value=Num;}</script>

 

再添加CSS样式

/*--------------商品详情页增加减少-------------*/.goods_gds {    height:35px;    display:block;    overflow:hidden;}.goods_font {    display:block;    float:left;        height:15px;    margin:8px 3px 0;    font-size:12px;}.goods_cut {    border:0 none;    cursor:pointer;    display:block;    float:left;    font-size:0;    height:15px;    line-height:0;    margin:8px 3px 0;    width:15px;    padding-right:0px;    _padding-right:0px;}input.goodsBuyBox,input.number {    border:1px solid #DDDDDD;    float:left;    font-size:10px;    height:18px;    line-height:18px;    margin:5px 5px 5px 5px;    padding:0;    text-align:center;}.goods_add {    border:0 none;    cursor:pointer;    display:block;    float:left;    font-size:0;    height:15px;    line-height:0;    margin:8px 3px 0;    width:15px;}.goods_number_tit{    display: block;    background:none;    text-align:left;    padding-left:5px; }
