拼接字符串

拼接在写js的时候常常用到

1.html部分

 <tr class="table-header">
                <td></td>
                <td class="mingcheng"></td>
                <td class="faren"></td>
                <td class="dianhua"></td>
                <td><img src=""/></td>
                <td></td>
                <td class="operate">
                    <button class="EditSupp" type="button">编辑</button>
                    <button class="DelSupp" type="button">删除</button>
                </td>
 </tr>

2.js拼接

var trStr="<tr class="table-header">"+
                "<td>"+"</td>"+
                "<td class="mingcheng">"+"</td>"+
                "<td class="faren">"+"</td>"+
                "<td class="dianhua">"+"</td>"+
                "<td>"+"<img src=""/>"+"</td>"+
                "<td>"+"</td>"+
                "<td class="operate">"+
                    "<button class="EditSupp" type="button">编辑</button>"+
                    "<button class="DelSupp" type="button">删除</button>"+
                "</td>"+
            "</tr>"；
