My Change Client Script doesn't populating expected output

Hi Community!

Hope you are fine!


I am having a requirement and that was quite simple.
While learning new about catalog items and behaviour, I stuck with this issue.

In a catalog item, I want to populate the groups for which the opened for is the group manager. For that I have created my own script. But somehow, it is failing. I need your help here to sort this out. Please check my script. I have used GlideAjax and Script Include for this. (Suggestions are accepted on which approach can be best for better efficiency and platform health)

My ScriptInclude: getUserGroupsForCatalog

Glide AJAX enabled : Checked

Script: 

var getUserGroupsForCatalog = Class.create();
getUserGroupsForCatalog.prototype = Object.extendsObject(AbstractAjaxProcessor, {

userGroups: function() {
var allGrps = [];
var user = this.getParameter('sysparm_user');
var grp = new GlideRecord('sys_user_group');
grp.addQuery('manager', user);
grp.query();
while (grp.next()) {
allGrps.push(grp.sys_id);
}
return JSON.stringify(allGrps);

},
type: 'getUserGroupsForCatalog'
});

and My onChange Catalog scripts:
Name: To show User groups
Variable Name: opened_for
Script:

function onChange(control, oldValue, newValue, isLoading) {
    if (isLoading || newValue == '') {
        return;
    }
    var requestedFor = g_form.getValue('opened_for');
    var ga = new GlideAjax('getUserGroupsForCatalog');
    ga.addParam('sysparm_name', 'userGroups');
    ga.addParam('sysparm_user', requestedFor);
    ga.getXMLAnswer(function(response) {
        if (response) {
            var output = JSON.parse(response);
            if (output.length > 0) {
                g_form.setValue('user_groups', output.join(','));
            } else {
                g_form.addErrorMessage('User is not the manager of any groups');
            }
        } else {
            g_form.addErrorMessage('User is not the manager of any groups');
        }
    });

}
While this was written for onChange, I also wanted to show the groups when the catalog item is loaded too. Please Suggest me answers. Thank you.

Greetings @imranshaik0 ,

 

Can you try replacing grp.sys_id with grp.getUniqueValue() within your push statement within the Script Include?

 

Also, would you be interested in clearing the value of the "opened_for" either BEFORE you set any value or within an Else statement if the passed in user is not a manager of any groups? That way, if the user changes the value of the "opened_for" field more than once, you won't be stacking or aggregating the groups of the second change on top of the first change in value.


Finally, I'll include a link to the always popular GlideAjax Cheat Sheet which always helps me in these situations. I hope this information helps!


GlideAjax Example Cheat Sheet (UPDATED) - ServiceNow Community


var getUserGroupsForCatalog = Class.create();
getUserGroupsForCatalog.prototype = Object.extendsObject(AbstractAjaxProcessor, {

    userGroups: function() {
        var allGrps = [];
        var user = this.getParameter('sysparm_user');
        var grp = new GlideRecord('sys_user_group');
        grp.addQuery('manager', user);
        grp.query();
        while (grp.next()) {
            allGrps.push(grp.getUniqueValue());
			//allGrps.push(grp.sys_id);
        }
        return JSON.stringify(allGrps);

    },
    type: 'getUserGroupsForCatalog'
});

Hi @lpruit2 ,

Thanks for the information. 

I have tried this too before but no luck.

But somehow I managed to solve it.

I used Advanced Reference Qualifier with the below condition and it worked.
"javascript: 'manager=' + current.variables.requested_by"

Enhancements and Best practices still accepted.

Thanks again.
