Below are some more useful scripts
1. How to get data from server-side to client-side.
Get single string value
Create a client callable script include
var AjaxUtil = Class.create();
AjaxUtil.prototype = Object.extendsObject(AbstractAjaxProcessor, {
getUserDetails:function(){
//adding sysparam_ before parameter is not necessary. It is only required only with function name while calling from client side
var userID=this.getParameter('userID');
var grUser=new GlideRecord('sys_user');
if(grUser.get(userID)){
return grUser.getDisplayValue();
}
return "";
},
type: 'AjaxUtil'
});Client-side code
function onLoad() {
//Type appropriate comment here, and begin script below
var grAjax=new GlideAjax('AjaxUtil');
grAjax.addParam('sysparm_name','getUserDetails');
grAjax.addParam('userID',g_user.userID);
grAjax.getXML(GetDetails);
//Type appropriate comment here, and begin script below
function GetDetails(response){
var answer=response.responseXML.documentElement.getAttribute('answer');
console.log('User Name:'+answer);
}
}Output-- check console logs
Get object/JSON
getUserDetails:function(){
var user={};
var userID=this.getParameter('userID');
gs.info('Upender:'+userID);
var grUser=new GlideRecord('sys_user');
if(grUser.get(userID)){
return JSON.stringify({'UserName':grUser.getDisplayValue(),'ID':grUser.getUniqueValue()});
}
return "";
}Output
Parse object values
var answer=response.responseXML.documentElement.getAttribute('answer');
var obj=JSON.parse(answer);
console.log('User Name:'+obj.UserName);
console.log('ID:'+obj.ID);
Get Array
var users=[];
var userID=this.getParameter('userID');
var grUser=new GlideRecord('sys_user');
if(grUser.get(userID)){
users.push(grUser.getDisplayValue());
users.push(grUser.getUniqueValue());
return JSON.stringify(users);
}
return "";Client-Side
var obj=JSON.parse(answer);
console.log('User List:'+obj);Output
2. Make catalog variables read-only with client script based on the state after item submission.
function onLoad(){
// use the correct state choice value
if(g_form.getValue('state') == 'closed confirmed'){
var fields = g_form.getEditableFields();
for (var x = 0; x < fields.length; x++) {
g_form.setReadOnly(fields[x], true);
}
}
}3. Get variables label, name, and value in BR.
var variables = current.variables.getElements();
var str = '';
for (var i = 0; i < variables.length; i++) {
var question = variables[i].getQuestion();
var variableName = question.getName();
var variableLabel = question.getLabel();
var variableValue = question.getDisplayValue();
if(variableName.indexOf('Price')>-1 || variableLabel.indexOf('Price')>-1)
continue;
if (variableValue != '' && variableValue !='false') {
str = str + variableLabel + ' - ' + variableValue + '\n';
}
}4. Combine two object's key
var a = {
"a": "1",
"b": "2"
};
var b = {
"c": "1",
"d": "2"
};
gs.print(JSON.stringify(merge(a,b)))
function merge(from,to){
for (var name in from){
var mached=false;
for(var dt in to){
if(dt==name)
mached=true;
}
if(!mached)
to[name]=from[name];
}
return to;
}
Output
Script: {"c":"1","d":"2","a":"1","b":"2"}
