Alert to show dot walk field

[Poorva Bhawsar]

Hi Community,

On incident form, when user selects business service it should show a popup which contains operational status of the business service which user has selected.

Here is my script include.

var TMUtils = Class.create();

TMUtils.prototype = Object.extendsObject(AbstractAjaxProcessor, {

    getCIStatus: function() {

        var ci = this.getParameter('sysparm_ci');

        var gr = new GlideRecord ('cmdb_ci_service');

        gr.addQuery('sys_id', ci);

        gr.query();

        if(gr.next()){

            return gr;

        }

        else{

            return '';

        }

    },

    type: 'TMUtils'

});

Here is my client script.

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

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

        return;

    }

    var ci = g_form.getValue('business_service');

    var ga = new GlideAjax('TMUtils');

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

    ga.addParam('sysparm_ci', ci);

    ga.getXML(CallBack);

    function CallBack(response) {

        //var answer = response.responseXML.documentElement.getAttribute("answer");

        //alert(g_form.setDisplayBox('The status of this Business Application is: ' + ci.operational_status));

        alert('The status of this Business Application is: ' + ci.operational_status);

        //alert('HI2' + ci.operational_status);

    }

}

But its not showing the alert.

Hi @Poorva Bhawsar ,

I found few errors in your script please check below,

1. function Callback corrected to callback

2. You were returning ci.operational_status  which will not work you have to get the values from script include and then capture it in answer variable

3.In client script closing flower bracket  was in wrong place 

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
    if (isLoading || newValue === '') {
        return;
    }

    var ci = g_form.getValue('business_service');
    var ga = new GlideAjax('TMUtils');
    ga.addParam('sysparm_name', 'getCIStatus');
    ga.addParam('sysparm_ci', ci);
    ga.getXML(callBack);
}
    function callBack(response) {
        var answer = response.responseXML.documentElement.getAttribute('answer');
        //var userData = answer.split(',');
        // alert('The status of this Business Application is: ' + answer[0]);
            alert('The status of this Business Application is: ' + answer);

    }

in script include dont return the object instead return the value which you want 

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

    getCIStatus: function() {
        var ci = this.getParameter('sysparm_ci');
        var gr = new GlideRecord ('cmdb_ci_service');
        gr.addQuery('sys_id', ci);
        gr.query();
        if(gr.next()){
            gr.operational_status.getDisplayValue();
        }
        else{
            return '';
        }
    },

    type: 'TMUtils'
});

Hi @Poorva Bhawsar ,

Please refer to the sample codes : https://www.servicenow.com/community/developer-forum/alert-a-dot-walked-field/m-p/1922903

I have already used the getreference function but if use this then it will not show the name of the status it will only show the value. For that i need to use script include and call that script include inside client script.

Hi @Poorva Bhawsar 

Please use this in alert:

alert('The status of this Business Application is: ' + g_form.getValue('business_service.operational_status'));
