java另存為

① java中實現另存為的代碼

保存代碼功能，可以參考下面的代碼。

代碼如下:
function runCode(obj) {
var winname = window.open('', "_blank", '');
winname.document.open('text/html', 'replace');
winname.opener = null // 防止代碼對父頁面修改
winname.document.write(obj.value);
winname.document.close();
}
function saveCode(obj) {
var winname = window.open('', '_blank', 'top=10000');
winname.document.open('text/html', 'replace');
winname.document.write(obj.value);
winname.document.execCommand('saveas','','');
winname.close();
}

function oCopy(obj){
obj.select();
js=obj.createTextRange();
js.execCommand("Copy");
alert("提示：代碼已經被成功復制！");
}
