Skip to main content

To highlight all keywords on all elements. (Excluding input form and text area)

I created two types of patterns.

・【 pattern_1 】

window.addEventListener("load", (highlight) => {
    const str1 = ["browser", "Browser"];
    const str2 = ['extension', 'Extension', 'add-on', 'Add-on', 'Add-On','拡張機能'];
    const str3 = ['Edge', 'edge'];
    const str4 = ['Firefox', 'firefox'];
    const str5 = ['Chrome', 'chrome'];

    function handleTextNode(textNode) {
        const newSpan = document.createElement('span');
        const origText = textNode.textContent;

        if (textNode.nodeName !== '#text' ||
            textNode.parentNode.nodeName === 'TEXTAREA' ||
            textNode.parentNode.nodeName === 'FORM' ||
            textNode.parentNode.nodeName === 'OPTION' ||
            textNode.parentNode.nodeName === 'INPUT' ||
            textNode.parentNode.nodeName === 'SELECT' ||
            //     || textNode.parentNode.nodeType === 3
            //     || textNode.nodeName !== "#document"
                 textNode.parentNode.nodeName === 'SCRIPT' ||
            //     || textNode.parentNode.nodeName === 'STYLE'
            textNode.parentNode.nodeName === 'A'
            //     || textNode.parentNode.nodeName === 'P'
            //     || textNode.parentNode.nodeName === 'SPAN'
            //     || textNode.parentNode.nodeName === 'H1'
            //     || textNode.parentNode.nodeName === 'H2'
            //     || textNode.parentNode.nodeName === 'EM'
        ) {
            return;
        }
        //----- Keyword group 1 Processing content -----//
        for (let i = 0; i < str1.length; i++) {
            // Create class
            let newHtml_1 = origText.replaceAll(str1[i], "<span class='highlighted_1'>" + str1[i] + "</span>");
            if (newHtml_1 !== origText) {
                newSpan.innerHTML = newHtml_1;
                textNode.parentNode.replaceChild(newSpan, textNode);
            }
        }
        //----- Keyword group 2 Processing content -----//
        for (let j = 0; j < str2.length; j++) {
            // Create class
            let newHtml_2 = origText.replaceAll(str2[j], "<span class='highlighted_2'>" + str2[j] + "</span>");
            if (newHtml_2 !== origText) {
                newSpan.innerHTML = newHtml_2;
                textNode.parentNode.replaceChild(newSpan, textNode);
            }
        }
        //----- Keyword group 3 Processing content -----//
        for (let k = 0; k < str3.length; k++) {
            // Create class
            let newHtml_3 = origText.replaceAll(str3[k], "<span class='highlighted_3'>" + str3[k] + "</span>");

            if (newHtml_3 !== origText) {
                newSpan.innerHTML = newHtml_3;
                textNode.parentNode.replaceChild(newSpan, textNode);
            }
        }
        //----- Keyword group 4 Processing content -----//
        for (let m = 0; m < str4.length; m++) {
            // Create class
            let newHtml_4 = origText.replaceAll(str4[m], "<span class='highlighted_4'>" + str4[m] + "</span>");

            if (newHtml_4 !== origText) {
                newSpan.innerHTML = newHtml_4;
                textNode.parentNode.replaceChild(newSpan, textNode);
            }
        }
        //----- Keyword group 5 Processing content -----//
        for (let n = 0; n < str5.length; n++) {
            // Create class
            let newHtml_5 = origText.replaceAll(str5[n], "<span class='highlighted_5'>" + str5[n] + "</span>");

            if (newHtml_5 !== origText) {
                newSpan.innerHTML = newHtml_5;
                textNode.parentNode.replaceChild(newSpan, textNode);
            }
        }

    }

    let textNodes = [];
    let nodeIter = document.createNodeIterator(document.body, NodeFilter.SHOW_TEXT);
    let currentNode;
    while (currentNode = nodeIter.nextNode()) {
        textNodes.push(currentNode);
    }

    textNodes.forEach(function(el) {
        handleTextNode(el);
    });

Regarding pattern 2, there is an anomaly that cannot be successfully migrated to some links.

Pattern 1 does not have the same problems as pattern 2 so far, so I think pattern 1 is ideal programming in comparison.

However, not all elements are highlighted in common with both Pattern 1 and Pattern 2.

(Excluding input form and text area) How should I write to emphasize every word of every element?
