BMR計算器：在BMR計算器中用瘦體重代替體重

我使用美國海軍公式修改了身體脂肪計算器。中的計算器提供 1. BMR 2.最小熱量需求 3.身體脂肪BMR計算器：在BMR計算器中用瘦體重代替體重

計算器工作良好，但我想的基礎代謝率到利用瘦體重，而不是重量（形式提供）

我在BMR計算之前增加了wt1 = wt-（wt/100 * fatPercent）。

控制檯顯示沒有錯誤，但我執行腳本時沒有得到任何結果。不知道如何糾正這一點。

在此先感謝

你輸出結果只有重量在磅規定。

謝謝，我沒有意識到這一點。但是我仍然不明白這個問題。爲什麼其他人不工作？如果選擇kg，wt的值保持不變。如果選擇磅，wt轉換爲kgs。那麼可以做些什麼來糾正腳本的其餘部分？ –

if（document.cal_frm.opWeight.value ==「1」）{/ *這是代碼，表示輸出* /} –

感謝您的幫助。爲了向所有人澄清，我添加了第二個條件語句，其中的選項值爲0（公斤數）-------- if（document.cal_frm.opWeight.value ==「0」）{document.getElementById（'feedback'）document.getElementById ）.innerHTML =「

您的BMR是：」+ BMR +「
」+「最低卡路里要求是：」+（Math.round（dailyCal））+「;
」+「您的身體脂肪是」+ fatPercent +「％」。 +「;

」; } ------ –
