一、第一步：如图，单击鼠标右键，新建一个文本文档。二、第二步：将以下内容复制黏贴到文本文档。 var JiaJianNum = 0; var TenNineNum = 0; var n = 0; var Str = ; var a, b; while (1 5) JiaJianNum = JiaJianNum + 1; JiaJian = JiaJianNum % 2; TenNineNum= TenNineNum + 1; TenNine = TenNineNum % 4; if (TenNine = 0) a = parseInt(10 * Math.random(); b = parseInt(10 * Math.random(); if (TenNine = 1) a = parseInt(10 * Math.random()+1); b = parseInt(10 * Math.random()+1); if (TenNine = 2) a = parseInt(10 * Math.random(); b = parseInt(10 * Math.random()+1); if (TenNine = 3) a = parseInt(10 * Math.random()+1); b = parseInt(10 * Math.random(); if (JiaJian = 1) if (a != 0 | b != 0) if (a + b = 10) n = n + 1; StrTemp = Str; Str = a + + + b + = + ; if (Str != StrTemp) if (n 20 & n 40 & n 60 & n = 80) document.getElementById(ha4).innerHTML = document.getElementById(ha4).innerHTML + Str; else JiaJianNum = JiaJianNum - 1; TenNineNum = TenNineNum - 1; if (JiaJian = 0) if (a != 0 | b != 0) if (a - b 0) n = n + 1; StrTemp = Str; Str = b + - + a + = + ; if (Str != StrTemp) if (n 20 & n 40 & n 60 & n = 80) document.getElementById(ha4).innerHTML = document.getElementById(ha4).innerHTML + Str; else n = n + 1; StrTemp = Str; Str = a + - + b + = + ; if (Str != StrTemp) if (n 20 & n 40 & n = 60) document.getElementById(ha3).innerHTML = document.getElementById(ha3).innerHTML + Str;
