js 工具方法

格式化时间

format = (t) =>{
    var time = new Date(t);
    var y = time.getFullYear();
    var m = time.getMonth()+1;
    var d = time.getDate();
    var h = time.getHours();
    var mm = time.getMinutes();
    var s = time.getSeconds();
    return y+'-'+this.add0(m)+'-'+this.add0(d)+' '+this.add0(h)+':'+this.add0(mm)+':'+this.add0(s);
}

将数据转换为保留两位小数的数据

returnFloat = (value) => {
    var value=Math.round(parseFloat(value)*100)/100;
    var xsd=value.toString().split(".");
    if(xsd.length==1){
        value=value.toString()+".00";
        return value;
    }
    if(xsd.length>1){
        if(xsd[1].length<2){
            value=value.toString()+"0";
        }
        return value;
    }
}
