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

关于如何解决此问题的任何想法，还是我可以忽略它？
答案 0 :(得分：0)
希望您已经定义了“ toType”，“ isWindow”和“ isFunction”功能-
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 || 0
type = toType( obj );
if ( isFunction( obj ) || isWindow( obj ) ) {
return false;
}
return type === "array" || length === 0 ||
typeof length === "number" && length > 0 && ( length - 1 ) in obj;
}

我再次查看了我的代码，并按了@CertainPerformances链接后发现了问题。
在以下内容之前，我忘记了“ $”：
if($('#doc-bar-chart').length > 0) {
...
}
大头巴掌
