我想通过使用纯 Java文字来强调花on的操作者。

<title>Syntax Highlighting Example</title>

<style>

    * {

        background: #000;

        color: white;

        font-size: 30px;

    }

    /* CSS styles for syntax highlighting */

    .keyword {

        color: blue;

        font-weight: bold;

    }

    .string {

        color: green;

    }

    .comment {

        color: gray;

        font-style: italic;

    }

</style>
<pre>

    <code id="code">

        // Example JavaScript code

        function greet(name) {

            if (name === "Alice") {

                console.log("Hello, " + name + "!");

            } else {

                console.log("Greetings, " + name + "!");

                console.log( Greetings,   + name +  ! );

            }

        }

        greet("Bob");

    </code>

</pre>

<script>

    // Syntax highlighting function

    function highlightSyntax() {

        // Get the code element

        var codeElement = document.getElementById( code );

        // Get the code text

        var codeText = codeElement.textContent;

        // Regular expression patterns for syntax elements

        var patterns = [

            { regex: /"(?:\.|[^\"])*"/g, className:  string  }, // Double quotes

        patterns.forEach(function (pattern) {

                return  <span class="  + pattern.className +  ">  + match +  </span> ;

            });

        });

        // Apply keyword highlighting

        keywords.forEach(function (keyword) {

            var regex = new RegExp( \b  + keyword +  \b ,  g );

            codeText = codeText.replace(regex,  <span class="keyword">  + keyword +  </span> );

        });

        function escapeRegExp(string) {

            return string.replace(/[.*+?^${}()|[]\]/g,  \$& );

        }

        // Testing the regular expressions

        var code = [

             x = y + 5 ,

             if (x > y) { ,

             result = x == y ,

             if (a <= b && b != c) { ,

        ];

        var matches = [];

        code.forEach(function (line) {

            regexes.forEach(function (regex) {

                var result = line.match(regex);

                if (result) {

                    matches = matches.concat(result);

                }

            });

        });

        console.log( Matches: , matches);

        // var codeExamples = [

        // Set the updated code HTML

        codeElement.innerHTML = codeText;

    }

    // Call the syntax highlighting function

    highlightSyntax();

我期望也能够强调经营者。 如同关键词和插图一样,在不使用任何框架或图书馆的情况下,上述图像也强调了这一点。
