javaweb 一些小节记录一

1.springMVC 学习点击checkbox的条目取某个值

/*slectck table的ID*/
var stationIds = "";
function change() {
	var tbodyObj = document.getElementById('slectck');
	$("table :checkbox").each(function(key, value) {
		var stationId = tbodyObj.rows[key].cells[1].innerHTML;
		if ($(value).prop('checked')) {
			if(!contains(stationIds,stationId)){  
				stationIds+=stationId+",";  
            }
		} else{
			if(contains(stationIds,stationId)){  
				stationIds=stationIds.replace((stationId+","),"");  
            } 
		}
	})
}

function contains(obj, ele) {  
    if(obj==""){  
        return;  
    }  
    /*若参数obj为字符串时，需要转换成数组*/  
    var arr = obj.split(",");  
    var i = arr.length;  
    while (i--) {  
        if (arr[i] == ele) {  
            return true;    
        }    
    }    
    return false;    
}

2.js 通过jdbc从数据库取得getTimestamp时间进行转换成Strng

function getMyDate(str){  
    var oDate = new Date(str),  
    oYear = oDate.getFullYear(),  
    oMonth = oDate.getMonth()+1,  
    oDay = oDate.getDate(),  
    oHour = oDate.getHours(),  
    oMin = oDate.getMinutes(),  
    oSen = oDate.getSeconds(),  
    oTime = oYear +'-'+ getzf(oMonth) +'-'+ getzf(oDay) +' '+ getzf(oHour) +':'+ getzf(oMin) +':'+getzf(oSen);//最后拼接时间  
    return oTime;  
};  
//补0操作  
function getzf(num){  
    if(parseInt(num) < 10){  
        num = '0'+num;  
    }  
    return num;  
}
