笔记之_javascript操作

Posted 2020-10-15 莫轩ASL

格式化日期：yyyy-mm-dd格式
function FormatDate(strTime) {
                var date = new Date(strTime);
                return date.getFullYear() + "-" + (date.getMonth() + 1) + "-" + date.getDate();
            }
            alert(FormatDate(new Date()));
数组对象排序：升序
var arr = [{‘name‘: ‘abc‘,‘age‘: 20}, {‘name‘: ‘cde‘,‘age‘: 19}, 
{‘name‘: ‘dfc‘,‘age‘: 25}, {‘name‘: ‘bde‘,‘age‘: 21}, ];
arr.sort(function(a, b) {
                return a.age - b.age;
            })
            document.getElementById("mylist").onclick = function() {
                alert("222");
                alert(arr[3].age);
                alert(new Date().getFullYear());
                alert(new Date().getYear());
                alert(new Date().getMonth());
            }];
