逃脱&用于在邮件客户端中显示（mailto 链接）

发布于 2024-11-18 04:17:16 字数 393 浏览 4 评论 0原文

我有一个像这样的 JavaScript 函数：

var strBody = encodeURI(window.location.href);
var strSubject = encodeURI(document.title);
var mailto_link = "mailto:?subject=" + encodeURI(strSubject) + "&body=" + strBody;

此代码在超链接的 onclick 事件上执行，并打开邮件客户端 (mailto://)。然而，页面标题有几个&符号，但标题仅在第一个 & 之前被选取。该 url 始终会被获取。

转义 & 的正确 JavasSript 是什么？并将其显示在邮件客户端的主题行中？

I have a JavaScript function like so:

var strBody = encodeURI(window.location.href);
var strSubject = encodeURI(document.title);
var mailto_link = "mailto:?subject=" + encodeURI(strSubject) + "&body=" + strBody;

This code is executed on a hyperlink's onclick event, and opens the mail client (mailto://). However, the title of the page has several & symbols, but the title is only picked up until the first &. The url is always picked up.

What is the correct JavasSript to escape the & and display it in the mail client's subject line?

var encoded_body = encodeURIComponent(window.location.href);
var encoded_subject = encodeURIComponent(document.title);
var mailto_link = "mailto:?subject=" + encoded_subject + "&body=" + encoded_body;

应该这样做（encodeURIComponent 而不是 encodeURI）。

在您的原始代码中，您还错误地对主题进行了双重编码（一次在第2行，然后再次在第3行）。

我冒昧地重命名了您的变量，以便更清楚地表明它们包含编码的主题和正文，而不是原始文本。

var encoded_body = encodeURIComponent(window.location.href);
var encoded_subject = encodeURIComponent(document.title);
var mailto_link = "mailto:?subject=" + encoded_subject + "&body=" + encoded_body;

should do it (encodeURIComponent instead of encodeURI).

In your original code you were also incorrectly double encoding the subject (once on line 2, and then again on line 3).

I took the liberty of renaming your variables to make it clearer that they contain the encoded subject and body, as opposed to the original text.
