Tips for changing font tags to span tags

One challenge I'm facing is replacing all instances of a font tag with a color attribute.

<font color="red">Some text</font>

I want to replace it with:

<span style="color: red;">Some text</span>

After some research on StackOverflow, I came across this helpful article and attempted to implement similar code: Javascript JQuery replace tags

Below is the jQuery loop I've created:

Iterate through the content of a div
Retrieve the font's color attribute
Replace the font tags with span tags
Apply a CSS style attribute containing the appropriate color

Unfortunately, the current implementation is not working as expected. It throws an error saying 'replaceWith' is not a function.

$('font').each(function () {
    var color;
    $(this).replaceWith(function () {
        color = $(this).attr("color");
        return $('<span>').append($(this).contents());
    });
    $(this).find("span").attr("style", "color:" + color);
});

If you have any suggestions or solutions, please share them! Your assistance would be highly appreciated.

There's no need to iterate through each element individually, as replaceWith can handle it efficiently.

$("font").replaceWith(  //Locates all font tags and replaces them with a new element
    function(){
        var tag = $(this);
        return $("<span/>")  //Creates a new span element
                   .html(tag.html())  //Sets the content of the new span to that of the original font tag
                   .css("color", tag.attr("color"));  //Sets the text color using the attribute value
    }
);

Although this response may be a bit delayed, I believe it is still valuable to share.

If your font tags contain attributes beyond just color (such as face, size), the following code snippet will address all of them:

HTML (Example)

<font color="red" size="3">Some text</font>
<br />
<font color="blue" face="Verdana">Some text</font>

jQuery (Javascript):

$(function () {
    var fontSizes = [ 
        'xx-small', // 1
        'x-small',  // 2
        'small',    // 3
        'medium',   // 4
        'large',    // 5
        'x-large',  // 6
        'xx-large'  // 7
    ];

    $('font').replaceWith(function () {
        var attrs = this.attributes;
        var span = $('<span />').append($(this).contents());

        for (var i = 0; i < attrs.length; i++) {
            var name = attrs[i].name;
            var value = attrs[i].value;

            if (name.indexOf('face') >= 0) {
                name = 'font-family';
            }

            if (name.indexOf('size') >= 0) {
                name = 'font-size';
                value = fontSizes[value - 1];
            }

            span.css(name, value);
        }

        return span;
    });
});
