	alert(eval(str));
</script>

　　

 

 

              <button type="button" id="gfyButton" class="btn btn-info btn-sm" action="querySelect(this,event)">

执行css方法

    _self.listOption.loadSuccess = function(){
        $(".datagrid-btable tr").find("td[field='gfyId']").css({"text-decoration":"underline","color":"#367fa9"});
    };
　　eval(_this.listOption.loadSuccess());
