這段代碼爲什麼會出錯？

Question

$("#main").animate({ 
display: "block", 
width: "70%", 
opacity: 0.4, 
marginLeft: "0.6in", 
fontSize: "3em", 
borderWidth: "10px" 
} 1500); 

這是jQuery。我在爭論清單「消息後得到」缺失）。怎麼了？

Answer 1

烏姆

} 1500); 

失蹤1500

可我建議使用http://www.jslint.com/之前逗號此的未來？如果你在一個代碼塊粘貼在那裏你會得到以下錯誤：

Error: 
Problem at line 8 character 3: Expected ')' and instead saw '1500'. 

} 1500); 

Problem at line 8 character 7: Missing semicolon. 

} 1500); 

Problem at line 8 character 7: Expected an identifier and instead saw ')'. 

} 1500); 

Problem at line 8 character 7: Stopping, unable to continue. (100% scanned). 

Implied global: $ 1 

後

，它它很容易看到你的錯誤必須在8號線..

Answer 2

你需要一個逗號在結束（目前} 1500);）的持續時間，這樣才：

$("#main").animate({ 
display: "block", 
width: "70%", 
opacity: 0.4, 
marginLeft: "0.6in", 
fontSize: "3em", 
borderWidth: "10px" 
}, 1500); 

Answer 3

$("#main").animate({ 
display: "block", 
width: "70%", 
opacity: 0.4, 
marginLeft: "0.6in", 
fontSize: "3em", 
borderWidth: "10px" 
}, 1500); // you have forgotten the comma here...
