Uncaught ReferenceError: g_form is not defined

[ramireddy]

I wants to display an sample error message from client side on the web page. So, I created following test page. But it's showing the error in browser console tab, "Uncaught ReferenceError: g_form is not defined".

Here is my page:

<?xml version="1.0" encoding="utf-8" ?>
<j:jelly trim="false" xmlns:j="jelly:core" xmlns:g="glide" xmlns:j2="null" xmlns:g2="null">
<g:ui_form>
   <input type="button" onclick="return validate();" value="Save"/>
</g:ui_form>
</j:jelly>

My client script:

function validate()
{
   alert("Validating");
   g_form.addErrorMessage('This is an error');
   return false;
}

On click of the button, I am getting the alert message. But it's not displaying the error message on the form. What am I missing here?

Not sure that g_form is working on a ui page

take a look here. There is a couple of workarounds, but sadly you ain't alone...

g_form not initialized on a custom CMS page

Thank you,

Is there any alternative way in servicenow, we can display a message to user on client-side(apart from javascript alerts)??

Thanks

Hi Ram,

Can you try something like this in your client script

1. function validate()  
2. {  
3. var g_form=new GlideForm(); // I have added this
4. alert("Validating");  
5.   g_form.addErrorMessage('This is an error');  
6.   return false;  
7. }  

Thanks
