我已附加html和我的問題的屏幕截圖。我有一個DIV容器（DIV ID=ctl00_m_g_a788a965_7ee3_414f_bff9_2a561f8ca37d_ctl00_pnlParentContainer），容器內部有2個DIV（一個用於左列TITLE（DIV ID=dvTitles），另一個用於右列MONTH（DIV ID=dvMilestones）。TITLE列的寬度始終是靜態的（即135px，在DIV裏面設置一個TD），右邊div會動態增長（即顯示5月，6月，7月）如何獲得父DIV寬度並設置子DIV寬度
注意：我已經在2個div上浮動了，設置爲自動在右邊的div。父div有一個設置寬度。我需要內部右div包括一個水平滾動條時，已達到最大寬度。
我不知道如何設置寬度和在什麼div讓這個工作。最外面的div是我需要的寬度（我相信）。 DIV id=WebPartctl00_m_g_a788a965_7ee3_414f_bff9_2a561f8ca37d
我希望這是有道理的。感謝您提供的任何幫助。不知道我是否可以用CSS或jQuery來做到這一切。

您可以在jQuery中使用'width（）'獲取元素的寬度。 – Niklas
