私はjavascriptプログラムを試していますが、問題が発生しました。プログラムが突然私のブラウザに遅れをとっています(おそらく無限ループ)、理由はわかりません。
function fullscreen() {
if (document.body.requestFullScreen) {document.body.requestFullScreen();}

var bash = document.createElement('span');

document.body.appendChild(bash);

bashPause(3);
bashWrite('Build v. 0.1.01-release (x86_64-pc)\n');
bashPause(2);
bashWrite('Connecting');
bashPause(35, '.');
bashWrite('Error, unknown user. See connect.log for futher information.\n');
bashPause(2);
bashWrite('none@m ~ $ >>');
bashCursor(true);
bashPrint();
jsFiddleにアップロードしました-http ://jsfiddle.net/uQcCP/
プログラムは次の間にフリーズします:
bashWrite('Error, unknown user. See connect.log for futher information.\n');
と
bashPause(2);
助けてくれますか?どうもありがとう。
