把注意力集中在最后一个命令上。 这就是我的问题所在。 在它中，我尝试检测消息的开头是否有*math add。 然后，我尝试检查消息是否包含非整数字（通过将消息转换为数组），然后尝试将它们相加（如果所有的字都是整数），并得到一个结果，可以作为消息发送。 下面是有问题的命令
if(spited[0] == markro){
if(!spited[1]){
msg.reply('there needs to be a math function to use')
return;
}
switch (spited[1]) {
case 'add':
if(!spited[2]){
msg.reply('you need something to add')
} else {
let thestuff = msg.content.split(' ').splice(markro, 1).slice('add', 1)
thestuff.forEach(elem => {
if(!isNaN(elem)){
para_meter = true
}
})
if(para_meter == true){
msg.reply('these are not integers')
para_meter = false
return;
}
var reduced = 0
thestuff.forEach(eleme => {
reduced += eleme
})
msg.channel.send(reduced)
}
break;
default:
break;
}
}
每当我实际尝试使用它时，通过bots命令，它只会响应'0*math)。 我该如何解决这个问题
（我很感激长代码是可滚动的，而且不在一个块中）
如果要将数组中的所有数字相加，可以使用reduce来完成。 只需在添加之前检查类型即可。
像这样的东西应该能奏效。
null
// ~ Original ~
// * Numbers are typed as such (not strings)
/** const myArray = [{}, [], "a", 1, "b", 3, "c", 5]; **/
// ~ Updated ~
// * Numbers are in string form (same as you are
// receiving the data from the API)
const myArray = [{}, [], "a", "1", "b", "3", "c", "5"];
const result = addNumbers(myArray);
console.log(result); // 9
function addNumbers (arr = []) {
if (!Array.isArray(arr)) {
throw new Error(
`[addNumbers] Parameter type is '${typeof arr}', need Array!`
);
}
return arr.reduce((a, v) =>
(isNaN(Number.parseInt(v)) ? 0 : Number(v)) + a, 0);
}
