次のスクリプトを使用します。
<script type="text/javascript">
window.document.onload = function(e){
var aheight = document.getElementById("a").offsetHeight;
var bheight = document.getElementById("b").offsetHeight;
if(aheight > bheight) {
document.getElementById("b").offsetHeight = aheight;
}else {
document.getElementById("a").offsetHeight = bheight;
}
}
</script>

<div id="a" class="grid_6" style="background-color: #ff00ff">
<div class="block-border">
Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.

<div id="b" class="grid_6" style="background-color: #ffff00">

これを使用して、ページの 2 つの DIV 間の高さを等しくします。このスクリプトをできるだけ早く動作させるには、このスクリプトを配置するのに最適な場所を教えてください。また、window.document.onload はこれに最適なトリガーですか? 別の方法として、要素 ID "a" と "b" がロードされている DIV でトリガーできますか? DIVS の変更がサイズであることをユーザーが見ないようにしたいだけです。
