How to clear a specific message at the top of the form

[jmweli]

Hi ServiceNow Community Developers,

Is there a way to clear a specific message at the top of the form? Right now I am using gs.clearMessages() however the problem with this API is that clears all messages at the top of the form even the ones I don't want to clear at that point.

Here is an example: I have a message that gets displayed at the top of the form by an onLoad client script, then I have a boolean (true / false ) field that displays a message at the top of the form depending on its value. If checked it displays the message, if unchecked it clears the message. I am doing all this in this boolean field by means of a onChange client script. The problem is when I uncheck this boolean field it then clears all the messages at the top of the form even the one that was put there by an onLoad client scripts. Is there a way I can overcome this issue? Please advise.

Thanks,

Johannes

Hi Subhajit,

Thanks for your suggestion. I managed to get this to work. Basically what I did was on the onchange client script where the gs.clearMessages() was clearing all messages out I went to the messages that were unintentionally getting cleared and checked how they were set up in the first place. I then included in my onchange client script the same condition that was setting them up and I got the desired behavior. So basically I set them back after unintentionally clearing them. In the end this was way easier than I thought.

This is a little hackish but it works...

This will only work on Desktop versions of ServiceNow. The Mobile / Android apps will not allow manipulation of the DOM.

I had a requirement where I needed to display a loading data message to the user while I waited for an API to return.

Note: this will remove any other notification if the if statement returns true on another notification.

This is a client script that runs onLoad of the form, I am using setTimeout to simulate an API call return.

This will only work on a SCOPED application if you add the following system property to that application scope "glide.script.block.client.globals=false", this is because scoped applications by default block DOM manipulation.

function onLoad() {

  var loadingMessage = "This is a test from script";

      g_form.addErrorMessage("THIS IS AN ERROR");

      g_form.addInfoMessage(loadingMessage);

      setTimeout(function() {

              var notifications = document.getElementsByClassName("notification");

              for (var i = 0; i < notifications.length; i++) {

                      if (notifications[i].innerText == loadingMessage) {

                              notifications[i].remove();

                      }

              }

      }, 8000);

}

Sorry for bumping an old thread. I was wondering about the same and found a good solution (with a bit of DOM):

$j('#myInfoMessage').remove();

g_form.addInfoMessage('Simple Message', 'myInfoMessage');

Of course you can change the ID ('#myInfoMessage' and 'myInfoMessage') to anything, and it will only clear that specific message. I used it in an OnChange client script. When the specific field changed, I immediately delete this one specific message, and I only add it back if I have a response (calling AJAX).

Please try this and mark it as the answer so others can see as well
