catalog client script to check the duplicate value

[Ashwitha gandla]

Hi,

I have created a Catalog item which creates a new group. I want to create a Catalog client script to pop-up an error when user enters new_group_name which already exists in the group table.
Could you please suggest how to achieve this.

Thank you

Hello @Ashwitha gandla ,

Using an on change client script and must make a GlideAjax call to a script include and return the information you desire.

For this example, the below would work:

Catalog Client Script:

function onChange(control, oldValue, newValue, isLoading) {

   if (isLoading || newValue == '') {

      return;

   }

   //Type appropriate comment here, and begin script below

var ga = new GlideAjax('getgroupinfo');

ga.addParam('sysparm_name','groupname');

ga.addParam('sysparm_group',newValue);

ga.getXMLAnswer(dosomething);

function dosomething(response){

var answer = response;

if (answer){

alert('Group name already exists');

}

} 

}

Script Include: (Ensure Client Callable):

var getgroupinfo = Class.create();

getgroupinfo.prototype = Object.extendsObject(AbstractAjaxProcessor, {

   groupname: function() {

var userGR = new GlideRecord('sys_user_group');

if (userGR.get('name', this.getParameter('sysparm_group'))){

return true;

}

},

    type: 'getgroupinfo'

});
