Bootstrap Table 搜索框和查询功能

1..知识点bootstraptable 刷新和查询配置

2.提升js代码性能

1.减少全局变量声明

2.缓存dom节点查找结果

3.局部变量缓存全局变量 

/** 
 * @param col bootstraptable列表生成配置对象 
 */ 
var searchvalue ={};//查询匹配对象 
var $button = $('<div class="columns pull-right search-button"><button class="btn btn-default" type="button" name="refresh" title="查询"><i class="glyphicon glyphicon-search icon-search"></i></button></div>'); 
var $input = $('<div class="columns pull-right search-input"><input class="form-control" type="text" placeholder="搜索"></div>'); 
var $select = $('<div class="columns pull-right search-select"><select></select></div>'); 
var addsearchgroup = function(col) 
{ 
   // 插入选项 
   var button ,input,select; 
   button = $button;input = $input;select = $select;////局部变量缓存全局变量 提高代码性能 
   var selectdom = $select.find('select');////缓存dom节点查找结果 避免在循环里用 
   for(var i = 0; i < col.length; i++){ 
     if(col[i].visible != false){ 
       var $option = '<option value="'+col[i].field+'">'+col[i].title+'</option>'; 
       selectdom.append($option); 
     } 
   } 
   //插入多选框、输入框、按钮 
   $('.fixed-table-toolbar').append(button,input,select); 
} 
/* 
button = $button 
*/ 
searchaction($button); 
function searchaction(button){ 
  //写入上一次查询的条件 
   if(searchvalue.select != undefined){ 
     $select.find('select').val(searchvalue.select); 
   }; 
   if(searchvalue.input != undefined){ 
     $input.find('input').val(searchvalue.input); 
   }; 
   //写入查询条件 
   // 获取查询选项 
   button.click(function(){ 
      var option = $select.find('select').val(); 
      var inputval = $input.find('input').val(); 
      searchvalue.select =option; 
      searchvalue.inputval =inputval; 
   //定义刷新参数 
     if(inputval != ''){ 
       var param = { 
         url: swebrootpath+"/json/getajaxdata.jsp?v="+new date().gettime(), 
         query: { 
           filters:[ 
             {'colname':option,'filtertype':'like','filtervalues':inputval} 
           ] 
         } 
       } 
     }else{ 
       var param = { 
        url: swebrootpath+"/json/getajaxdata.jsp?v="+new date().gettime(), 
       } 
     } 
      // 刷新表格 
    $('#tablelist').bootstraptable('refresh',param); 
    }); 
}
