Bootstrap Table 搜索框和查询功能

/**

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 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>';
