爲什麼HTML窗體菜單在同一窗口/選項卡中打開URL？

Question

我想要在新標籤頁/窗口中打開菜單URL，我不希望它用所需的URL覆蓋當前頁面。消息標題被代碼塊「幫助」所掩蓋。只是爲了表明：我使用_blank，瀏覽器忽略它。

<FORM name="Menu_1a"> 
 
    <SELECT name="URL" onChange="if(options[selectedIndex].value) 
 
    window.location.href=(options[selectedIndex].value) " style="background-color: #CCFF99; font-weight: bold;"> 
 
    <option value="" selected="selected" style="background-color: #FFCC99; font-weight: bold;">---Select --></option> 
 
    <OPTION value="http://ezaca.tripod.com/index_acco.html" target="_self">Reset this menu</OPTION> 
 
    <!-- this works, except it replaces page instead of opening new --> 
 
    <OPTION value="http://www.jakob-schlaepfer.ch/en/decor/collection-a-m/" target="_blank">Background</OPTION> 
 
    <OPTION value="http://lyricstranslate.com/en/amor-eterno-love-eternal.html">Amor Eterno - Lyrics</OPTION> 
 
    <OPTION value="http://www.youtube.com/watch?v=7QuXKirNX3I">Amor Eterno - R. Durcal</OPTION>

Answer 1

如果你能在你需要的屬性target="_blank"添加到形成一個新的窗口提交form。

target屬性指定一個名稱或一個關鍵字，用於指示提交表單後收到的響應的顯示位置。

目標屬性定義瀏覽上下文（例如選項卡，窗口或內聯框架）的名稱或關鍵字。
