1、网上的代码:
<div class="demoTable"> 搜索商户: <div class="layui-inline"> <input class="layui-input" name="keyword" id="demoReload" autocomplete="off"> </div> <button class="layui-btn" data-type="reload">搜索</button></div> 在js加入初始化代码和定义加载方法 layui.use('table', function(){ var table = layui.table; //方法级渲染 table.render({ elem: '#LAY_table_user' ,url: 'UVServlet' ,cols: [[ {checkbox: true, fixed: true} ,{field:'id', title: 'ID', width:80, sort: true, fixed: true} ,{field:'aid', title: '商户', width:80, sort: true} ,{field:'uv', title: '访问量', width:80, sort: true,edit:true} ,{field:'date', title: '日期', width:180} ,{field:'datatype', title: '日期类型', width:100} ]] ,id: 'testReload' ,page: true ,height: 600 }); var $ = layui.$, active = { reload: function(){ var demoReload = $('#demoReload'); table.reload('testReload', { where: { keyword: demoReload.val() } }); } }; )};
绑定click点击事件
$('.demoTable .layui-btn').on('click', function(){ var type = $(this).data('type'); //注意顶一个括号中的格式,class用.id用#,中间有一个空格 active[type] ? active[type].call(this) : ''; });
此时点击查询按钮,会将keyword这个关键字传到后端,接下来就是自己处理查询关键字业务了。
到目前为止,搜索也有了,分页也有了,对了,分页会自动传到后端page,limit2个值到后台,相当于(pageindex,pagesize)
2、实践,
(1)html页面及javascript代码如下:
<!--index.html内容如下--> {% extends 'common.html'%} {% block content %} <div class="layui-row"> <form class="layui-form layui-col-md12 we-search" id="form_gen_data"> <div class="layui-inline"> <label class="layui-form-label">手机号</label> <input class="layui-input" placeholder="手机号" name="phone" id="phone"> </div> <div class="layui-inline"> <label class="layui-form-label">身份证</label> <input class="layui-input" placeholder="身份证" name="idno" id="idno"> </div> <div class="layui-inline"> <label class="layui-form-label">姓名</label> <input class="layui-input" placeholder="姓名" name="name" id="name"> </div> <div class="layui-inline"> <label class="layui-form-label">crfuid</label> <input class="layui-input" placeholder="crfuid" name="crfuid" id="crfuid"> </div> </form> </div> <div class="weadmin-block"> <button class="layui-btn" id="query_extra" style="display:none;">扩展功能</button> <button class="layui-btn" id="query_thumb">开始查询</button> <button class="layui-btn" id="query_limit">额度查询</button> <button class="layui-btn" id="query_member">会员查询</button> <button class="layui-btn" id="query_account">账户查询</button> <button class="layui-btn" id="query_sms" οnclick="return false;" data-type="reload">短信验证码查询</button> <div class="layui-collapse" lay-accordion> <div class="layui-colla-item"> <h2 class="layui-colla-title">扩展功能</h2> <div class="layui-colla-content"> {% for business in common_business %} <button class="layui-btn layui-btn-danger common_business" id="{{business.business_code}}" data-type="{{business.business_code}}" data-extra="{{business.business_is_extra}}">{{business.business_name}}</button> {% endfor %} </div> </div> </div> </div> <div class="layui-collapse"> <div class="layui-colla-item"> <h2 class="layui-colla-title">日志</h2> <div class="layui-colla-content layui-show"><textarea placeholder="" id="log" class="layui-textarea" name="desc"></textarea></div> </div> <div class="layui-colla-item"> <h2 class="layui-colla-title">附加信息</h2> <div class="layui-colla-content layui-show" id="extra_info"> </div> </div> </div> <table class="layui-hide" id="table_message" lay-filter="user"></table> <script type="text/javascript" src="/static/lib/layui/layui.js" charset="utf-8"></script> <script> layui.use('table', function(){ var table = layui.table; //方法级渲染 table.render({ elem: '#table_message' ,url: '/sms/message' ,method:'post' ,where: { phone: '', env_tools:parent.window.env_tools } ,cellMinWidth: 100 ,cols: [[ {checkbox: true, fixed: true} ,{field:'id', title: 'ID', sort: true,width:120, fixed: true} ,{field:'phone', title: '手机号',width:120} ,{field:'content', title: '短信内容', sort: true} ,{field:'create_time', title: '发送时间',width:160} ]] ,id: 'testReload' ,page: true ,height: 500 }); var $ = layui.$, active = { reload: function(){ var demoReload = $('#phone'); $('.env_message').html('当前操作环境:'+ parent.window.env_tools); //执行重载 table.reload('testReload', { page: { curr: 1 //重新从第 1 页开始 } ,where: { phone: demoReload.val(), env_tools:parent.window.env_tools } }); } }; $('.weadmin-block #query_sms').on('click', function(){ var type = $(this).data('type'); active[type] ? active[type].call(this) : ''; }); }); </script> {% endblock %}
(2)后台代码如下:
@toolsbp.route('/') @toolsbp.route('/index',methods=['GET','POST']) def index(): if request.method=='POST': data={} data['data']='' data['code']=0 data['msg']='查询成功' env=request.form.get('env_tools') if env is None: return json.dumps(data) phone=request.form.get('phone') where='' if phone: where="where phone like '%(phone)s'"%{'phone':'%'+phone+'%'} dbinfo=env_config.ENV_LIST.get(env.upper()).get('sms_platform') dbtool=MysqlPool.MysqlPool(dbinfo.get('db_name')) result=dbtool.getAll("select * from %(table_name)s.sms_send_record %(where)s order by create_time desc limit %(page)d,%(pagesize)d;"%{'where':where,'table_name':dbinfo.get('table_name'),'page':int(request.form.get('page'))-1,'pagesize':int(request.form.get('limit'))}) data['data']=result if result: data['count']=len(result) else: data['count']=0 return json.dumps(data,cls=MysqlPool.DateEncoder) return render_template('tools/index.html')
(3)页面功能如下:
