The onclick functionality is not functioning properly within email communications

My JavaScript code contains an AJAX call within Datatables, and this snippet of code is causing an issue:

{   "data": null, 
    "width": "10%",
    "render": function(data){
        icon2 = '<center><button type="button" class="btn btn-info m-btn m-btn--icon m-btn--icon-only btn-sm" ' +
            'data-toggle="m-tooltip" title="" onclick="sendEmail('+data.email+')" data-placement="top" data-original-title="' + 'Send Email' + ' "> <i class="la la-envelope"></i></button>';
        icon2 += '</center>';

    return icon2; }
}

In addition, I have a function defined as follows:

function sendEmail(email){
   console.log("email: ", email);
}

However, upon clicking the button, I encounter the following error message: **Uncaught SyntaxError: missing ) after argument list**.

I am curious if there are any alternative solutions to resolve this issue.

Answer №1

When dealing with literals, it's important to remember that they need to be quoted.

You cannot simply write:

onclick="sendEmail(<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="4f2d202d0f2a372e223f232a612c2022">[email protected]</a>)"

A quick workaround is to add a few ' to the data, but this assumes there are no other issues with the data (like containing ', ", or new lines).

The recommended approach is to:

  1. Encode the data as JSON to make it a valid JavaScript literal
  2. Encode special characters in HTML to prevent parsing issues

For example:

const email = data.email;
const js_safe_email = JSON.stringify(email);
const html_safe_email = js_safe_email
     .replace(/&/g, "&amp;")
     .replace(/</g, "&lt;")
     .replace(/>/g, "&gt;")
     .replace(/"/g, "&quot;")
     .replace(/'/g, "&#039;");
icon2 = '<center><button type="button" class="btn btn-info m-btn m-btn--icon m-btn--icon-only btn-sm" ' +
        'data-toggle="m-tooltip" title="" onclick="sendEmail('+html_safe_email+')" data-placement="top" data-original-title="' + 'Send Email' + ' "> <i class="la la-envelope"></i></button>';

While this method may seem messy, it is better than combining strings of data within JS embedded in HTML. It's generally recommended to use DOM methods instead.

Upon closer inspection, the issue seems to lie within the "render": function(data){ segment. While the function itself is properly closed, it appears that the enclosing hash is not.

{   "data": null, 
    "width": "10%",
    "render": function(data){
        icon2 = '<center><button type="button" class="btn btn-info m-btn m-btn--icon m-btn--icon-only btn-sm" ' +
            'data-toggle="m-tooltip" title="" onclick="sendEmail('+data.email+')" data-placement="top" data-original-title="' + 'Send Email' + ' "> <i class="la la-envelope"></i></button>';
        icon2 += '</center>';

    return icon2; }
}

Please take note of the extra } present at the end of the code snippet.
