本篇文章主要是對js根據日期判斷星座的示例代碼進行了介紹，需要的朋友可以過來參考下，希望對大家有所幫助
代碼如下: function xingzuo() { var start = 1901, date=document.getElementById("txtDay").value, month=document.getElementById("txtMonth").value;; with (document.getElementById("txtXZ")){ if (month == 1 && date >=20 || month == 2 && date <=18) {value = "水瓶座";} if (month == 1 && date > 31) {value = "Huh?";} if (month == 2 && date >=19 || month == 3 && date <=20) {value = "雙魚座";} if (month == 2 && date > 29) {value = "Say what?";} if (month == 3 && date >=21 || month == 4 && date <=19) {value = "白羊座";} if (month == 3 && date > 31) {value = "OK. Whatever.";} if (month == 4 && date >=20 || month == 5 && date <=20) {value = "金牛座";} if (month == 4 && date > 30) {value = "I'm soooo sorry!";} if (month == 5 && date >=21 || month == 6 && date <=21) {value = "雙子座";} if (month == 5 && date > 31) {value = "Umm ... no.";} if (month == 6 && date >=22 || month == 7 && date <=22) {value = "巨蟹座";} if (month == 6 && date > 30) {value = "Sorry.";} if (month == 7 && date >=23 || month == 8 && date <=22) {value = "獅子座";} if (month == 7 && date > 31) {value = "Excuse me?";} if (month == 8 && date >=23 || month == 9 && date <=22) {value = "室女座";} if (month == 8 && date > 31) {value = "Yeah. Right.";} if (month == 9 && date >=23 || month == 10 && date <=22) {value = "天秤座";} if (month == 9 && date > 30) {value = "Try Again.";} if (month == 10 && date >=23 || month == 11 && date <=21) {value = "天蠍座";} if (month == 10 && date > 31) {value = "Forget it!";} if (month == 11 && date >=22 || month == 12 && date <=21) {value = "人馬座";} if (month == 11 && date > 30) {value = "Invalid Date";} if (month == 12 && date >=22 || month == 1 && date <=19) {value = "摩羯座";} if (month == 12 && date > 31) {value = "No way!";} } }
