Question

4 つの数値を使用して 24 を取得する方法を計算するプログラムがあります。

The game 24 (aka. Combine 4) gives you 4 numbers, and you have to do operations using all four numbers to make 24. Some of the questions are quite tricky! If you need help getting the solution, click the button below and follow the directions! It will give you a list of all the solutions. One operation you may not be familliar with is modulo. It takes 2 numbers, divides to first number by the second number, and returns the remainder.<br><br>
+ is addition<br>
- is subtraction<br>
* is multiplication<br>
/ is division<br>
^ is exponents<br>
% is modulo<br><br>

ただし、IE で新しいウィンドウを開くと、スクロールバーが表示されないため、すべてのソリューションが表示されないことがあります。ただし、Google Chrome では問題なく動作します。

を使用したい場合は、 plalxの回答javascriptに従うことができます

それ以外の場合は、CSS を使用する場合:

html,body {
    overflow:scroll; // I'm not sure whether your results always need a scroll-bar to see it, if yes use `auto` 
}

この css をポップアップウィンドウに挿入するには:

solutionWindow.document.write("<style>html,body { overflow:scroll; }</style>);

style.cssまたは、ファイルに追加するだけです

試してみてください：

var solutionWindow = window.open('','_blank','scrollbars=1,width=500,height=1000');
