Hiii Everyone,
我想设置源网址'通过jquery输入类型="文件"。我想替换“没有选择的文件”#39;具体的网址。
• Occurs check: cannot construct the infinite type: t ~ t -> t1
• In the first argument of ‘f’, namely ‘f’
In the expression: f f
In an equation for ‘sa’: sa f = f f
• Relevant bindings include
f :: t -> t1
(bound at fp-through-lambda-calculus-michaelson.hs:9:4)
sa :: (t -> t1) -> t1
(bound at fp-through-lambda-calculus-michaelson.hs:9:1)
我想用
设置这个URl属性$("#audio0").attr("src", url);
我曾尝试使用" title"的set属性并尝试使用标签集属性但没有任何问题。请任何人帮助我摆脱这个问题。提前谢谢。
