是“删除"吗?Google Chrome浏览器中的保留关键字? [英] Is "remove" a reserved keyword in Google Chrome?

问题描述

我有一个有趣的问题，我想我找到了根本原因，但是我想确定一下.我有一个链接，调用了称为remove()的函数.除Chrome之外的所有浏览器均未使用该功能.但是，即使我按以下示例简化了功能，单击的链接在Chrome中也消失了.我已经看到了以下问题:无法使用下载"作为javascript中的函数名称.但是，在链接中，我没有看到有关删除"作为保留关键字的任何信息.我的问题是，关于这个关键字，我是正确的吗?如果是这样，我在哪里可以找到Google关键字列表?我已经搜索过，但没有发现这是其他任何地方的问题.

I have an interesting problem, and I think I got to the root of it, but I wanted to be sure. I have a link that calls a function called remove(). All browsers except Chrome had no issues with the function. However, the link that is clicked disappeared in Chrome, even when I simplified the function as in the example below. I have seen this question: Can't use "download" as a function name in javascript. In the links, however, I did not see anything about "remove" as a reserved keyword. My question is this, I am correct about this being a keyword? If so, is there anywhere I can find a list of Google keywords? I have searched and have not found this to be a problem anywhere else.

<a href="javascript:void(0)" onclick="remove()">Remove</a>

JavaScript:

Javascript:

function remove(){
 alert("Hi");
}

推荐答案

Chrome中的元素具有 .remove()方法，该方法可以自动删除元素，而不必从中删除父母.

Elements in Chrome have a .remove() method which allows for self-removal of an element instead of having to do it from the parent.

问题在于，使用属性处理程序时，您会获得不同的作用域链.该范围链包括元素本身以及 document .这意味着元素和 document 的所有属性都显示为变量.

The trouble is that when using attribute handlers, you get a different scope chain. That scope chain includes the element itself, as well as the document. This means that all properties of the element and document show up as variables.

因为您将函数命名为 remove()，并且由于它是全局函数/变量，所以它被 .remove 属性(现在是变量)遮盖了).这可以通过警报看到.如果您将处理程序更改为:

Because you named your function remove(), and because it's a global function/variable, it is being shadowed by the .remove property (now variable) on the element itself. This can be seen with an alert. If you change your handler to:

onclick="alert(remove)"

...您将得到类似的东西:

...you'll get something like:

function remove() { [native code] }

因此，并不是保留它，而是将其用作最终遮盖全局的属性.

So it's not that it's reserved, but rather that it's used as a property which ends up shadowing the global.

要解决此问题，请直接使用全局变量:

To fix it, either use the global directly:

onclick="window.remove()"

或更改函数名称.
