question Select the Devices into list collector based on Requested For field. in ITSM forum

Select the Devices into list collector based on Requested For field.

Hi Everyone,

Requiremnt: I have created the catalog item. Once the "Requested For" is selected, the "Assigned Asset" of this "Requested For" will be auto-populated in the "Test" field.

I have written the Below client callable script include and On-change Catalog Client script. However, it is not working as expected. Could you please help me on this?

Script Include:

var GetAssetDetails = Class.create();

GetAssetDetails.prototype = Object.extendsObject(AbstractAjaxProcessor, {

getAssets: function() {

var requestedFor = this.getParameter('sysparm_requestedFor');

var assetList = [];

var gr = new GlideRecord('alm_asset');

gr.addQuery('assigned_to', requestedFor);

gr.query();

while (gr.next()) {

assetList.push(gr.sys_id.toString());

}

return new JSON().encode(assetList);

type: 'GetAssetDetails'

});

Catalog Client Script:

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

if (isLoading || newValue == '') {

return;

}

var ga = new GlideAjax('GetAssetDetails');

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

ga.addParam('sysparm_requestedFor', g_form.getValue('requested_for'));

ga.getXMLAnswer(function(response) {

if (response) {

var assetSysIds = JSON.parse(response);

if (assetSysIds.length > 0) {

g_form.setValue('test', assetSysIds.join(','));

} else {

g_form.setValue('test', '');

}

} else {

alert('No response from server');

}

});

}

Thanks,

Rajesh

What kind of variable is "test"?

I'm assuming the Catalog Client Script is running on change of the "requested_for" variable. Is that correct?

Hi @Jim Coyne , Thanks for your quick response

“Test” field type is “list collector”.

yes, it’s running on change catalog client script for requested for field.

Oh, I see it in the title of the post now, sorry about that. And sorry for the delay in responding. Did you ever figure it out?

Here's an updated Script Include:

It looks like you've created the Script Include in the Global scope. If so, you need to be careful of the name so that ServiceNow does create a Class with the same name in a new release. It is not a problem if it is in a custom Scoped App as it is yours and you control what is in it. I don't like the "U_" prefix, but it protects your class somewhat, although not a guarantee. You could use you client code as a prefix instead.

You might want to have one or a few Script Includes that contain your functions otherwise you'll end up with a lot of them. Group the functions into Script Includes by what they do or tables they look at.

And I've changed the name of the function to make it clear as to what it will return. And take a look at the comments I've added.

Updated Catalog Client Script:

Again, take a look at the comments within the code. This will work in a Service Portal, but not the regular UI: needs a bit of tweaking the change the contents of the List Collector
