    });
    //给状态为-1的价位红色
    $('#pro_manage_show_grid').datagrid({
        rowStyler:function(index,row){
             if(row.taskStatus==-1){
                  return 'background-color:red;';
             }            

        }

    });

    //$('#pro_manage_show_grid').datagrid('loadData', getData());
    var p = $('#pro_manage_show_grid').datagrid('getPager'); 
    if (p){ 
    $(p).pagination({ 
        onBeforeRefresh:function(){ 
        alert('before refresh'); 
        } 
    }); 
    }   

});

//自适应
$(window).resize(function(){
    $("#pro_manage_list").layout('resize');     
}); 


//此界面，设置成定时刷新界面。每两分钟刷新一次
function myrefresh(){ 
       window.location.reload(); 
} 
setTimeout('myrefresh()',1000*60*2); //每两分钟刷新一次

function query(){
    //Please wait...
    $.blockUI({css: { 
    border: 'none', 
    padding: '15px', 
    backgroundColor: '#000', 
    '-webkit-border-radius': '10px', 
    '-moz-border-radius': '10px', 
    opacity: .5, 
    color: '#fff'}});
    //
    $.ajax({
        url:path+'/monitor/f1/queryTasklogList.do',
        type: 'POST',
        dataType: 'json',
        data: $("#dataForm").serialize(),
        success: function(msg){
            var posData = eval(msg);
            $('#pro_manage_show_grid').datagrid('loadData',posData);
            $.unblockUI();
        },
       error: function(msg){
                $.unblockUI();
                alert("操作失败！");
        }
    });
}

function querylog(){

    var row = $('#pro_manage_show_grid').datagrid('getSelected');

    var _url = path+'/monitor/f2/queryLog.do?workFlowId='+ row.workFlowRunId;

    window.parent.initCenter("日志信息",_url,"bb",true);

}
