fontSize: "3em", 
borderWidth: "10px" 
} 1500); 

这是jQuery。我在争论清单“消息后得到”缺失）。怎么了？

Answer 1

乌姆

} 1500); 

失踪1500

可我建议使用http://www.jslint.com/之前逗号此的未来？如果你在一个代码块粘贴在那里你会得到以下错误：

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 

后

，它它很容易看到你的错误必须在8号线..

Answer 2

你需要一个逗号在结束（目前} 1500);）的持续时间，这样才：

$("#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...
