2、left-radius:7px; border-bottom-right-radius:7px; border-top-left-radius:7px; border-top-right-radius:7px </style><script><!这个是js函数-!>var numresult; var str; 1 / 4function onclicknum( nums ) str = document.getElementById("MyText"); str.value = str.value + nums; function on

3、clickclear() str = document.getElementById("MyText"); str.value = "" function onclickresult() str = document.getElementById("MyText"); numresult = eval(str.value); str.value = numresult; </script><meta http-equiv="Content-Type" content="text/html
