js处理数据的方式记录
条件判断
JavaScript把null、undefined、0、NaN和空字符串''视为false,其他值一概视为true。
js中常用的数据处理记录
//下拉框选中项的内容
$("#subsidyType option:selected").text();
//IE有时处理中文乱码
var _borrowName = encodeURIComponent($.trim($("#userName").val()));
window.open(encodeURI('http://api.xxx.cn/share/qqim?url=${weburl}/user/register.html?ui=${ui}&title=我在某某某网站帮你抢到注册壕礼&summary=快来领取和我一起赚钱吧!'));
// input控件选择器
$("input[name='username']")
// 连续对一个对象的属性处理
$(".offline_on_detail").attr("style","display:none").attr("data-status","off");
时间工具
//时间处理文件-------------------------------------------------------------
var now = new Date(); //当前日期
var nowDayOfWeek = now.getDay(); //今天本周的第几天
var nowDay = now.getDate(); //当前日
var nowMonth = now.getMonth(); //当前月
var nowYear = now.getYear(); //当前年
nowYear += (nowYear < 2000) ? 1900 : 0;
//格局化日期:yyyy-MM-dd
function formatDate(date) {
var myyear = date.getFullYear();
var mymonth = date.getMonth()+1;
var myweekday = date.getDate();
if(mymonth < 10){
mymonth = "0" + mymonth;
}
if(myweekday < 10){
myweekday = "0" + myweekday;
}
return (myyear+"-"+mymonth + "-" + myweekday);
}
//获得本周的开端日期
function getWeekStartDate() {
var weekStartDate = new Date(nowYear, nowMonth, nowDay - nowDayOfWeek+1);
return formatDate(weekStartDate);
}
//获得本周的停止日期
function getWeekEndDate() {
var weekEndDate = new Date(nowYear, nowMonth, nowDay + (7 - nowDayOfWeek));
return formatDate(weekEndDate);
}
