What I am trying to do: As stated in the title, I want to set the CSS of a word if it is a reserved word.

HTML 

<html>
    <body>
        <code id="java">
            public static void main(String[] args)<br>
            {
                <pre>    System.out.println("Hello World!");</pre>
            }
        </code>
    </body>
</html>

jQuery

$(document).ready(function()
{
    // Get the text inside the code tags
    var code  = $("#java").text();

    // Split up each word
    var split = code.split(' ');

    // Array of reserved words
    var array = ["abstract","assert","boolean","break","byte","case",
                 "catch","char","class","const","continue","default",
                 "do","double","else","else if","enum","extends","final",
                 "finally","float","for","goto","if","import","implements",
                 "instanceof","int","interface","long","native","new","null",
                 "package","private","protected","public","return","short",
                 "static","strictfp","super","switch","synchronized","this",
                 "throw","throws","transient","void","volatile","while"];

    // Added when text contains a reserved word
    var css = {'font-weight':'bold','color':'#2400D9'}

    array = jQuery.map(array, function(n,i)
    {
        for (int j=0; j<array.length; j++)
        {
            if (split[i].contains(array[j]))
                split[i].css(css);
        }
    });
});

Problem: I have referred to the documentation for several methods (in the references section below), but I’m not too sure where the problem(s) lies. To narrow the issue down, my question(s) would be…

  1. Is .split() even a method in jQuery?
  2. Should I use a for loop to run through all the words in the array (to see if the code contains a reserved word) or is there a better approach (such as .each())?
  3. If I should use .each(), could someone please give me a simple example? I don’t understand the examples in the documentation.

    If I understood correctly, you can achieve what you want using $.inArray and wrapping the reserved word with a span tag. See my DEMO

    Edit: Below is from jQuery $.inArray documentation.

    $.inArray( value, array [, fromIndex] ) –

    valueThe value to search for.

    arrayAn array through which to search.

    fromIndexThe index of the array at which to begin the search. The
    default is 0, which will search the whole array.

    CSS

    .code {
    font-weight: bold;
    color: #2400D9;
}

    JS

    $(document).ready(function() {
    // Get the text inside the code tags
    var code = $("#java").html();

    // Split up each word
    var split = code.split(' ');

    // Array of reserved words
    var array = ["abstract", "assert", "boolean", "break", "byte", "case", "catch", "char", "class", "const", "continue", "default", "do", "double", "else", "else if", "enum", "extends", "final", "finally", "float", "for", "goto", "if", "import", "implements", "instanceof", "int", "interface", "long", "native", "new", "null", "package", "private", "protected", "public", "return", "short", "static", "strictfp", "super", "switch", "synchronized", "this", "throw", "throws", "transient", "void", "volatile", "while"];

    for (var j = 0; j < split.length; j++) {
        if ($.inArray(split[j], array) > 0) {
            split[j] = '<span class="code">' + split[j] + '</span>';
        }
    }

    $("#java").html(split.join(' '));
});
