想請問document.Show.MouseX.value的MouseX和是指令還是只是個名稱而已
還有這段document.Show.MouseX.value是指說在網頁中名稱為Show的form標籤中利用設計出名稱為MouseX的input標籤顯示"值" 不知道這樣解釋對不對(有點難翻...)
小弟剛入門不久
請各位大大幫忙解答
謝謝

問:想請問document.Show.MouseX.value的MouseX和是指令還是只是個名稱而已
答:MouseX是名稱,document.Show.MouseX.value是指令
問:document.Show.MouseX.value是指說在網頁中名稱為Show的form標籤中利用設計出名稱為MouseX的input標籤顯示"值"
答:基本上和你解釋得差不多,就是抓取表單(Show)裡面的文字方塊(MouseX)控制該欄位的值,根據程式上的寫法,是讓該文字方塊顯示tempX抓取到的值
※若解釋有誤還請大大們給予糾正
