[英]How to make a div to have same height to one div
我想將一個 div 的高度推到等於其他 div 的高度。 就我而言，我有 2 個 div：div 1 和 div 2。 我需要將 div 2 的高度推到等於 div 1 的高度。 無論 div 2 上的內容如何，高度都將等於 div 1。 如果 div 2 上的內容比 div 1 上的內容長，它將溢出 div 2。 就像下面描述的那樣：
是否可以使用 jquery、CSS 或它們的組合？ 我正在嘗試從其他問題中得到一些答案，但大多數情況不同。 這里的大多數問題都在 2 div 之間相等，而不是等於 1 div。
感謝您的任何幫助。
只有 css

嘗試，
window.onload=function()
{
$(div2 selector).css("height",$(div1 selector).css("height"));
}
使用純 Javascript，您可以在 DIV#1 上使用element.getBoundingClientRect()方法來獲取其實際高度值。 然后將其應用於 DIV#2 CSS 樣式：
var div1_height = document.querySelector("#div1").getBoundingClientRect().height;
document.querySelector("#div2").style.height = div1_height+"px";
找到你的 div 應該是的 div 的 id 並將你的 div 的高度設置為它。
例如，類 div1 是尺寸較小的 div，類 div2 是您需要將其大小更改為 div1 大小的 div，請執行以下操作：
$('.div2').attr('height',$('.div1').attr('height'));
