1.检查用户名中是否含有特殊字符:
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>检查输入数据中是否含有特殊字符</title> </head> <body> <script type="text/javascript"> var str = window.prompt("敢问阁下高姓大名?"); var arr = ["*","%","&","<",">","/","\\","!","@","#"] var length1 = str.length; var length2 = arr.length; var count = 0; for(var i=0; i<length1; i++){ for(var j=0; j<length2; j++){ if(str[i]==arr[j]){ count++; break; } } if (count!=0) {break;} } if (count==0) {document.write("用户名符合要求.");} if (count!=0) {document.write("用户名含有特殊字符.");} </script> </body> </html>
2.大多数人的一生只有2w多天:
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>活了多少天</title> </head> <body> <script type="text/javascript"> var str = window.prompt("交出你的出生日期,如:1990-08-24"); var arr = str.split("-"); for(var i=0,length=arr.length; i<length; i++){ arr[i] = Number(arr[i]); } var today = new Date().getTime(); var mybth = new Date(arr[0],arr[1]-1,arr[2]).getTime(); var days = parseInt((today-mybth)/1000/3600/24); alert("少年,你已经在这个伟大的星球生活了"+days+"天!!!"); </script> </body> </html>
