在JavaScript onClick事件处理程序中转义双引号

问题描述

下面的简单代码块可以在静态HTML页面中提供，但会导致JavaScript错误。你应该如何逃避onClick处理程序中的嵌入式双引号（即\xyz）？请注意，HTML是通过从数据库中提取数据而动态生成的，其数据是其他HTML代码的片段，可以是单个或双引号。似乎在双引号字符之前添加一个反斜杠并没有办法。

The simple code block below can be served up in a static HTML page but results in a JavaScript error. How should you escape the embedded double quote in the onClick handler (i.e. \"xyz)? Note that the HTML is generated dynamically by pulling data from a database, the data of which is snippets of other HTML code that could have either single or double quotes. It seems that adding a single backslash ahead of the double quote character doesn't do the trick.

<script type="text/javascript">
    function parse(a, b, c) {
        alert(c);
    }
</script>

<a href="#x" onclick="parse('#', false, '<a href=\"xyz'); return false">Test</a>
