Firefox Extension - How to use preference for a menulist? -

-

मैं की स्थिति को सहेजने के लिए टैग & lt; वरीयता & gt; कोड> & lt; menulist & gt; । लेकिन मुझे पता नहीं है कि मैं क्या गलत कर रहा हूं।

यहां मेरा कोड है: 

  & lt; प्राथमिकताएं & gt; & Lt; प्राथमिकता आईडी = "चुनिंदा pref1" नाम = "प्राथमिकता। नाम" प्रकार = "इंट" / & gt; & Lt; / वरीयताओं & gt; & LT; menulist & gt; & Lt; menupopup वरीयता = "चुनेंpref1" & gt; & Lt; menuitem label = "option 1" value = "1" / & gt; & Lt; menuitem label = "option 2" value = "2" / & gt; & Lt; menuitem label = "option 3" value = "3" / & gt; & Lt; menuitem label = "option 4" value = "4" / ​​& gt; & Lt; / menupopup & gt; & Lt; / menulist & gt;    
 
 
 मुझे पूरा यकीन है कि आप ऐसा नहीं कर सकते आपको बस प्रत्येक मेन्यूम्स पर एक आदेश को जोड़ना होगा, जो वरीयता को बदलता है आप "पॉपअपशोइंग" ईवेंट के लिए एक श्रोता भी जोड़ना चाह सकते हैं, जो वरीयता की जांच करता है और वर्तमान में चुने गए किसी भी चेकमार्क को चेक करता है।
