The code for 'Make a URL a clickable link' works fine for non-admin users, but not so well for globeadmin.

Here is what Globeadmin sees when logging in:

When globeadmin clicks on the Back button, then clicks on the button to open the Browse form again, the aforesaid error appears:

Code: Select all

For reference, here is the Browse form code:

Code: Select all

// ==============================
// Hide specific columns normally,
// but show them during nuPrint().
// ==============================

// Columns with hyperlinks (replace with correct column indexes!)
const hyperlinkColumns = [4, 5, 6]; // example: 1=audio, 2=video, 3=photo

// Function to hide columns
function hideColumns(cols) {
    cols.forEach(i => nuSetBrowseColumnSize(i, 0));
}

// Function to show columns (auto size)
function showColumns(cols) {
    cols.forEach(i => nuSetBrowseColumnSize(i, 'auto'));
}

// Hide columns by default (non-admins only)
if (!nuGlobalAccess()) {
    hideColumns(hyperlinkColumns);
}


// ==============================
// Hook into nuPrint()
// ==============================

(function() {
    // Keep a reference to the original nuPrint
    const originalNuPrint = window.nuPrint;

    window.nuPrint = function() {
        // Before print: show the hyperlink columns
        showColumns(hyperlinkColumns);

        // Call the original nuPrint function
        originalNuPrint();

        // After short delay, re-hide the columns (so Browse view looks normal again)
        setTimeout(() => {
            if (!nuGlobalAccess()) hideColumns(hyperlinkColumns);
        }, 2000);
    };
})();


// ==============================
// Your existing blank column logic
// ==============================

if (!nuGlobalAccess()) {
    var columnIndex = 0;
    nuSetBrowseColumnSize(columnIndex, 0);
}

{
    const hiddenColumns = hideBlankColumns();

    if (!nuGlobalAccess()) var columnIndex = 0;

    const columnsToExclude = [...new Set([columnIndex, ...hiddenColumns])];
    nuPrintExcludeColumns(columnsToExclude);
}

function hideBlankColumns() {
    const hiddenColumns = [];
    const browseDiv = document.getElementById('nuRECORD');
    if (!browseDiv) return hiddenColumns;

    const headers = browseDiv.querySelectorAll('.nuBrowseTitle');
    if (headers.length === 0) return hiddenColumns;

    const colCount = headers.length;
    const isColumnBlank = new Array(colCount).fill(true);
    const dataCells = browseDiv.querySelectorAll('.nuCell[data-nu-column]');

    dataCells.forEach(cell => {
        const colIndex = parseInt(cell.getAttribute('data-nu-column'));
        const content = cell.textContent.trim();
        if (content !== '' && colIndex >= 0) isColumnBlank[colIndex] = false;
    });

    for (let j = 0; j < colCount; j++) {
        if (isColumnBlank[j]) {
            nuSetBrowseColumnSize(j, 0);
            hiddenColumns.push(j);
        }
    }
    return hiddenColumns;
}

Here is the corrected code (thank you ChatGPT), making sure that it only runs once:

Code: Select all

// Prevent duplicate initialization
if (!window.hyperlinkColumnsInitialized) {
    window.hyperlinkColumnsInitialized = true;

    // ==============================
    // Hide specific columns normally,
    // but show them during nuPrint().
    // ==============================

    const hyperlinkColumns = [4, 5, 6]; // example: 1=audio, 2=video, 3=photo

    // Function to hide columns
    function hideColumns(cols) {
        cols.forEach(i => nuSetBrowseColumnSize(i, 0));
    }

    // Function to show columns (auto size)
    function showColumns(cols) {
        cols.forEach(i => nuSetBrowseColumnSize(i, 'auto'));
    }

    // Hide columns by default (non-admins only)
    if (!nuGlobalAccess()) {
        hideColumns(hyperlinkColumns);
    }

    // ==============================
    // Hook into nuPrint()
    // ==============================

    (function() {
        // Prevent re-wrapping nuPrint multiple times
        if (!window.nuPrintWrapped) {
            window.nuPrintWrapped = true;

            const originalNuPrint = window.nuPrint;

            window.nuPrint = function() {
                // Before print: show hyperlink columns
                showColumns(hyperlinkColumns);

                // Call the original print
                originalNuPrint();

                // Re-hide columns after delay
                setTimeout(() => {
                    if (!nuGlobalAccess()) hideColumns(hyperlinkColumns);
                }, 2000);
            };
        }
    })();

    // ==============================
    // Your existing blank column logic
    // ==============================

    if (!nuGlobalAccess()) {
        var columnIndex = 0;
        nuSetBrowseColumnSize(columnIndex, 0);
    }

    {
        const hiddenColumns = hideBlankColumns();

        if (!nuGlobalAccess()) var columnIndex = 0;

        const columnsToExclude = [...new Set([columnIndex, ...hiddenColumns])];
        nuPrintExcludeColumns(columnsToExclude);
    }

    function hideBlankColumns() {
        const hiddenColumns = [];
        const browseDiv = document.getElementById('nuRECORD');
        if (!browseDiv) return hiddenColumns;

        const headers = browseDiv.querySelectorAll('.nuBrowseTitle');
        if (headers.length === 0) return hiddenColumns;

        const colCount = headers.length;
        const isColumnBlank = new Array(colCount).fill(true);
        const dataCells = browseDiv.querySelectorAll('.nuCell[data-nu-column]');

        dataCells.forEach(cell => {
            const colIndex = parseInt(cell.getAttribute('data-nu-column'));
            const content = cell.textContent.trim();
            if (content !== '' && colIndex >= 0) isColumnBlank[colIndex] = false;
        });

        for (let j = 0; j < colCount; j++) {
            if (isColumnBlank[j]) {
                nuSetBrowseColumnSize(j, 0);
                hiddenColumns.push(j);
            }
        }
        return hiddenColumns;
    }
}
