更新:編輯的JavaScript代碼。現在在一些專欄中只有略微偏離。也許是一個像素或兩個。不知道爲什麼。邊框和填充寬度javascript
我需要獲取表格單元格的邊框和內部填充寬度。我打算從offsetWidth中減去這些值以獲取內容寬度,並使用它來設置另一個單元格的style.width。不幸的是,我找不到一種可靠的方式來獲得邊框和填充寬度。任何人有想法?
更新:我添加了下面的代碼來顯示我的實現。它仍然沒有正確對齊。 我試圖同步兩個表的列寬度;但是,表格寬度設置得比所有列的長度小,推動一些列不排隊。 表格寬度設置得太小。 :(

你打算使用jQuery嗎? – 2012-03-23 15:34:38
@ElliotBonneville你在jQuery中所做的一切都可以在純javascript中完成 – 2012-03-23 15:36:25
@ElliotBonneville我願意使用任何可以完成的工作。雖然JavaScript可以做任何jQuery可以做的事情,但由於它本身就是javascript本身,因此jQuery經常會用更少的麻煩和更多的樂趣來做到這一點。 :) – steventnorris 2012-03-23 15:39:40
