Return error statement from client script

[SHALIKAS]

I have a list collector variable called asset which refers to the hardware table. My requirment is that whenever any value selected which is of class hardware or server and has install status retired, then a message should be displayed in the form saying Value selected is not correct. How to do this

why not apply reference qualifier to allow selecting only Non Retired Install Status?

Then no scripting and validation required.

But the requirment is to display message also

I don't think it's a best UI experience to let users select a retired Asset and then show the info message

Instead apply simple reference qualifier and show a field message or help text that only Non-retired assets can be selected

If you still require then you can write onChange catalog client script + GlideAjax and check if any 1 asset is in retired status then show that message

Something like this but please enhance

function onChange(control, oldValue, newValue, isLoading) {
    if (isLoading || newValue == '') {
        return;
    }
    g_form.hideFieldMsg('asset');

    var ga = new GlideAjax('AssetValidation');
    ga.addParam('sysparm_name', 'validateAsset');
    ga.addParam('sysparm_sys_id', newValue);
    ga.getXMLAnswer(function(response) {
        if (response == 'invalid') {
            g_form.showFieldMsg('asset', 'Asset selected is not correct. Only non-retired assets can be selected', 'error');
        }
    });
}

Client callable Script Include

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

    validateAsset: function() {
        var assetSysId = this.getParameter('sysparm_sys_id').toString();
        var assetGR = new GlideRecord('cmdb_ci_hardware');
        assetGR.addQuery('sys_class_name', 'IN', 'cmdb_ci_hardware,cmdb_ci_server');
        assetGR.addQuery('sys_id', 'IN', assetSysId);
        assetGR.addQuery('install_status', '7');
        assetGR.setLimit(1);
        assetGR.query();
        if (assetGR.hasNext())
            return 'invalid';
        else
            return 'valid';
    }
});
