语法错误:函数体后面缺少 }
当在某处创建函数时出现语法错误时,就会出现 JavaScript 异常 "函数体后面缺少 }"。检查右大括号或圆括号的顺序是否正确。
¥The JavaScript exception "missing } after function body" occurs when there is a syntax mistake when creating a function somewhere. Check if any closing curly braces or parenthesis are in the correct order.

什么地方出了错?
¥What went wrong?
在某处创建函数时存在语法错误。还要检查任何右大括号或圆括号的顺序是否正确。更好地缩进或格式化代码也可能会帮助你看清丛林。
¥There is a syntax mistake when creating a function somewhere. Also check if any closing curly braces or parenthesis are in the correct order. Indenting or formatting the code a bit nicer might also help you to see through the jungle.
示例
忘记关闭大括号
¥Forgotten closing curly bracket
通常,函数代码中缺少大括号:
¥Oftentimes, there is a missing curly bracket in your function code:
function charge() {
if (sunny) {
useSolarCells();
} else {
promptBikeRide();
}
正确的是:
¥Correct would be:
function charge() {
if (sunny) {
useSolarCells();
} else {
promptBikeRide();
}
}
例如,当使用 IIFEs 或其他使用大量不同括号和大括号的结构时,它可能会更加模糊。
¥It can be more obscure when using IIFEs or other constructs that use a lot of different parenthesis and curly braces, for example.
(function () {
if (Math.random() < 0.01) {
doSomething();
}
)();
通常,不同的缩进或双重检查缩进有助于发现这些错误。
¥Oftentimes, indenting differently or double checking indentation helps to spot these errors.
(function () {
if (Math.random() < 0.01) {
doSomething();
}
})();
