SyntaxError:意外的令牌{在javascript中 [英] SyntaxError: Unexpected token { in javascript

问题描述

控制台出现问题时我遇到了一个问题

I am having an issue on my problem where the console is saying

SyntaxError: Unexpected token {

，我不确定它来自哪里.我是JS新手，只是学习这些东西.请介意指出我的括号在哪里出问题了.

and I'm not sure where it's coming from. I am a JS newbie, just learning this stuff. Would you mind pointing out where I am going wrong with my brackets please.

var myArray = [4, 6, 23, 10, 1, 3];

var arrayAdditon = function (arr) {
    var largestNumber = arr[0];
    var sumTotal;
    for (var i = 0; i < arr.length; i += 1) {
        if (arr[i] > largestNumber) {
            largestNumber = arr[i];
        }
    }
    for (var i = 0; i < arr.length; i += 1) {
        if (largestNumber) {
            console.log(largestNumber);
        } else (arr[i] != largestNumber) {
            sumTotal += arr[i];   
        }
    }
    if (largestNumber === sumTotal) {
        return true;
    } else {
        return false;
    }
}

推荐答案

我认为您的if ... else部分存在错误，请尝试更改为此.

I think you have a bug in your if...else part, try changing to this.

 if (largestNumber) {
     console.log(largestNumber);
 } else if (arr[i] != largestNumber) {
     sumTotal += arr[i];   
 }

如果这不起作用，请向我评论您遇到的全部错误.尝试在Firebug控制台中检查它. 希望对您有帮助.

If this doesn't work comment me the full error you got. Try to inspect it in firebug console. Hope this helps you.
