jquery - Chrome Throwing 无法使用“in”运算符搜索“length”

问题描述

我刚刚注意到 Chrome 显示此错误。但所有错误似乎都来自 jquery。我正在使用 3.3.1

jquery3.self-5af507e253c37e9c9dcf65064fc3f93795e6e28012780579975a4d709f4074ad.js?body=1:490 Uncaught TypeError: Cannot use 'in' operator to search for 'length' in <!DOCTYPE html><html><head><meta content="text/html; charset=UTF-8" http-equiv="Content-Type" /><title>Dashboard</title><meta name="csrf-param" content="authenticity_token" />

这是检测到错误的地方。它来自 jquery 文件而不是我的代码：

function isArrayLike( obj ) {

    // Support: real iOS 8.2 only (not reproducible in simulator)
    // `in` check used to prevent JIT error (gh-2145)
    // hasOwn isn't used here due to false negatives
    // regarding Nodelist length in IE
    var length = !!obj && "length" in obj && obj.length,
        type = toType( obj );

    if ( isFunction( obj ) || isWindow( obj ) ) {
        return false;
    }

    return type === "array" || length === 0 ||
        typeof length === "number" && length > 0 && ( length - 1 ) in obj;
}

关于如何解决这个问题的任何想法或者我可以忽略它吗？

解决方案

我再次查看了我的代码，并在关注@CertainPerformances 链接后发现了问题。

我忘记了以下之前的“$”：

   if($('#doc-bar-chart').length > 0) {
        ...   

        }

巨头一巴掌。
