Hi @Alon Grod 

By default, ServiceNow's  g_form.showFieldMsg treats text as plain string and escapes HTML tags.

OOB it is not supported. 

You need to write an onLoad Client Script that pushes a placeholder message and dynamically updates the DOM element  ( DOM is not recommended).

Refer  for DOM onload script:

Hello @Alon Grod ,

Here it look like :

You can try this code snippet :

function onLoad() {
    var fieldName = 'u_incident'; 
    var placeholder = "##placeholder##";
    var url = "https://google.com"; /
    
   
    g_form.showFieldMsg(fieldName, placeholder, 'info', false);
    
 
    try {
        var elements = document.getElementsByClassName("fieldmsg notification notification-info");
        if(elements.length > 0) {
            var str = elements[0].innerHTML;
            str = str.substring(0, str.indexOf(placeholder));
            elements[0].innerHTML = str + 'Please <a href="' + url + '" target="_blank">click here</a> for more information.';
        }
    } catch(e) {
        // Fallback or error handling
    }
}

Note : uncheck isolated script

@Alon Grod 

g_form.showFieldMsg doesn't support HTML so your requirement is not possible

You can inform your customer about this platform limitation and instead show infoMessage on form

Note: There are approaches to achieve this with DOM manipulation but it's not recommended to use

Hey @Alon Grod 

You can achieve this using DOM manipulation from an onLoad Client Script.

function onLoad() {
    g_form.showFieldMsg('u_priferia', 'Click here', 'info');
    setTimeout(function() {
        var msgs = document.querySelectorAll('.fieldmsg');
        msgs.forEach(function(msg) {
            if (msg.innerText.indexOf('Click here') > -1) {
                msg.innerHTML = '<a href="https://www.google.com" target="_blank">Click here</a>';
            }

        });

    }, 1000);
}

Important: Make sure Isolate Script is unchecked on the Client Script, otherwise DOM APIs such as document.querySelectorAll() will not be accessible.

Note: Direct DOM manipulation is generally not recommended in ServiceNow because DOM elements and CSS classes can change across releases, which may cause scripts to break after upgrades. Where possible, consider supported alternatives such as UI Macros, Formatters, HTML fields, or Workspace components depending on your use case.
