1. How to send more than one variable from server side script to client side while using GlideAjax?

Hi @sandeepgujj ,

Use below code to return multiple value from script in clude.

Server Side code

var AjaxUtils = Class.create();
AjaxUtils.prototype = Object.extendsObject(AbstractAjaxProcessor, {
    returnSimpleObject: function() {
        var obj = {};
        var sysId = this.getParameter('sysparm_sys_id');
        var almAssetGr = new GlideRecord("alm_asset");
        almAssetGr.addQuery('sys_id', sysId);
        almAssetGr.query();
        if (almAssetGr.next()) {
            obj.model = almAssetGr.getDisplayValue('model');
            obj.model_category = almAssetGr.getDisplayValue('model_category');
            
            var json = new JSON();
            var data = json.encode(obj); //JSON formatted string
        }
        return data;
    },
    type: 'AjaxUtils'
});

Client side code

function onLoad() {
    var ga = new GlideAjax('AjaxUtils');
    ga.addParam('sysparm_name', 'returnSimpleObject');
    ga.addParam('sysparm_sys_id', g_form.getValue('sys_id'));
    ga.getXML(showMessage);
}
function showMessage(response) {
    var answer = response.responseXML.documentElement.getAttribute("answer");
    g_form.addInfoMessage('JSON String: '+answer); //JSON String
    answer = answer.evalJSON(); //Transform the JSON string to an object
    g_form.addInfoMessage('Object: '+ answer);
    g_form.addInfoMessage('Asset Model: '+answer.model); //Display Asset Model
    g_form.addInfoMessage('Asset Category: '+answer.model_category); //Display Asset Category
}

Hi @sandeepgujj 

 

You can initialize an object with key-value pairs in the Script Include, then use JSON.stringify(jsonObject) to return it as a string. On the Client Script, you can use JSON.parse(response) to convert the string back into a JSON object and access its data.

Sample.

Client Callable Script Include

getJsonData: function() {  
    var data = { key1: "value1", key2: "value2" };  
    return JSON.stringify(data);  
}  

Client Script:

var ga = new GlideAjax('YourScriptIncludeName');  
ga.addParam('sysparm_name', 'getJsonData');  
ga.getXMLAnswer(function(response) {  
    var jsonData = JSON.parse(response);  
    console.log(jsonData.key1); // Output: value1  
    alert(jsonData.key1); // Output: value1  
});  

Cheers,

Tai Vu
