Help Related to GlideAjax and Script Include

[SandeepKSingh]

can anyone provide me the sample code for GlideAjax and Script include??

[Ravi Gaurav · Accepted solution]

Hello ,

use the below sample code:-

SI:-

var SampleScriptInclude = Class.create();
SampleScriptInclude.prototype = {
initialize: function() {
},

// This method can be called via GlideAjax
getGreeting: function(userName) {
// Return a greeting message
return 'Hello, ' + userName + '! Welcome to ServiceNow.';
},

type: 'SampleScriptInclude' // Name of the Script Include
};

CS:-

function onLoad() {
// Instantiate the GlideAjax object
var ga = new GlideAjax('SampleScriptInclude');

// Add a parameter that calls the method in the Script Include
ga.addParam('sysparm_name', 'getGreeting');

// Add any parameters that need to be passed to the Script Include method
ga.addParam('sysparm_userName', g_user.getFullName());

// Make the asynchronous call
ga.getXMLAnswer(function(response) {
// Handle the response from the Script Include
var greeting = response.responseXML.documentElement.getAttribute("answer");
alert(greeting); // Display the greeting message in an alert
});
}

One Very Simple Example I can help you out is with :-

// Script Include: MyGlideAjaxScriptInclude
// Accessible from Client-Side Scripts: Yes
// Client Callable: Yes

var MyGlideAjaxScriptInclude = Class.create();
MyGlideAjaxScriptInclude.prototype = {
initialize: function() {
},

// Method to be called from the client-side
getServerData: function(param1, param2) {
// Example logic
var result = "Hello " + param1 + " and " + param2;
return result;
},

// Required method
type: 'MyGlideAjaxScriptInclude'
};
CS :-

// Client Script: onLoad or onChange, depending on your use case
function onLoad() {
var ga = new GlideAjax('MyGlideAjaxScriptInclude');

// Adding parameters (can be any value)
ga.addParam('sysparm_name', 'getServerData'); // sysparm_name must match the function name in the Script Include
ga.addParam('param1', 'World');
ga.addParam('param2', 'Universe');

// Sending the request and processing the response
ga.getXMLAnswer(function(response) {
var answer = response.responseXML.documentElement.getAttribute("answer");
alert("Response from server: " + answer); // Display the response
});
}

try it

@SandeepKSingh Here is the sample code for Script Include.

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

    getCurrentDateTime: function() {
        var currentDateTime = new GlideDateTime();  // Get the current date and time
        return currentDateTime.toString();          // Convert it to a string and return
    },

    type: 'GetCurrentDateTime'
});

Here is the sample code for onLoad script having GlideAjax call to the above script include.

function onLoad() {
    // Create a GlideAjax object and pass the Script Include name
    var ga = new GlideAjax('GetCurrentDateTime'); 
    
    // Specify the method name in the Script Include that should be called
    ga.addParam('sysparm_name', 'getCurrentDateTime');
    
    // Send the request and process the response with the provided callback function
    ga.getXMLAnswer(processResponse);
}

// Callback function to process the response
function processResponse(response) {
    var currentDateTime = response;  // The response is the current date and time as a string
    
    // Display the current date and time in an alert (or use it as needed)
    alert("Current Date and Time: " + currentDateTime);
    
    // Alternatively, set the value in a field
    // g_form.setValue('your_field_name', currentDateTime);
}

Hope this helps.

One more best example :-

Scenario:

When a user selects a department from a dropdown, the manager's name associated with that department should automatically populate in a separate field.

1. Script Include

This Script Include retrieves the manager's name based on the department selected.

// Script Include: GetDepartmentManager // Accessible from Client-Side Scripts: Yes // Client Callable: Yes var GetDepartmentManager = Class.create(); GetDepartmentManager.prototype = { initialize: function() { }, getManagerByDepartment: function(departmentSysId) { var managerName = ''; var deptGR = new GlideRecord('cmn_department'); if (deptGR.get(departmentSysId)) { var managerSysId = deptGR.manager; // Assuming 'manager' is a reference field to 'sys_user' if (managerSysId) { var userGR = new GlideRecord('sys_user'); if (userGR.get(managerSysId)) { managerName = userGR.getValue('name'); } } } return managerName; // Return manager's name }, // Required method type: 'GetDepartmentManager' };

2. Client Script

This Client Script runs when the department field is changed and auto-populates the manager field.

// Client Script: onChange // Applies to the Department field function onChange(control, oldValue, newValue, isLoading) { if (isLoading || newValue == '') { return; } var ga = new GlideAjax('GetDepartmentManager'); ga.addParam('sysparm_name', 'getManagerByDepartment'); // Calls the function in the Script Include ga.addParam('departmentSysId', newValue); // Passes the selected department's sys_id ga.getXMLAnswer(function(response) { var managerName = response.responseXML.documentElement.getAttribute("answer"); g_form.setValue('manager_field', managerName); // Auto-populates the manager's name field }); }
