Bootstrap Table 搜索框和查询功能

/ 
  @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); 
}
