Methods use in Callout

Making Callout Active/InActive 

On calling any calloutprototype method you can set that callout to active so that if callout is already active then will not call again. See below code example 

//if callout is active and receiving value parameter to callout is not valid then return 

if (this.isCalloutActive() || value == null || value.toString() == "") { 

return""; 

} 

//make callout active 

this.setCalloutActive(true); 

In the end of the callout prototype method after successfully execute your logic, make this callout inactive by below method 

this.setCalloutActive(false); 

Get/Set Value in Callout 

You can get the current active tab fields value with method mTab.gelValue(“ColumnName”) 
 

var netsalary,gross, basic, hra; 

// get values 

basic = VIS.Utility.Util.getValueOfDecimal(mTab.getValue("VAT_BasicSalary")); 

hra = VIS.Utility.Util.getValueOfDecimal(mTab.getValue("VAT_HRA")); 

Following example demonstrates how you can set the values of the fields in the current active tab with method mTab.setValue(“ColumnName”,value); 

mTab.setValue("VAT_NET", netsalary); 

mTab.setValue("VAT_Gross", gross); 

You can explore more example of callouts in following folder. 

“VIS/Scripts/Model/callouts.js”, callout run at client side  

Full Example of Callout as below (the sample code you can find from Demo Partner Kit) 

//initialize your module prefix code 

//Here MPC is VAT 

; VAT = window.VAT || {}; 
 

; (function (VAT, $) { 
 

/** 

• Callout Class 

• must call this function 

• VIS.CalloutEngine.call(this, [className]); 

*/ 

function CalloutEmployeeSalary() { 

VIS.CalloutEngine.call(this, "VAT.CalloutEmployeeSalary"); //must call 

}; 
 

/** 

*Inherit CallourEngile Class  

*/ 

VIS.Utility.inheritPrototype(CalloutEmployeeSalary, VIS.CalloutEngine);//inherit CalloutEngine 

//Callout Method defined as Function prototype 

CalloutEmployeeSalary.prototype.netSalary = function (ctx, windowNo, mTab, mField, value, oldValue) { 

if (this.isCalloutActive() || value == null || value.toString() == "") { 

return""; 

} 

this.setCalloutActive(true); 

try { 

var netsalary, gross, basic, hra, pf, tds; 

// get values 

basic = VIS.Utility.Util.getValueOfDecimal(mTab.getValue("VAT_BasicSalary")); 

hra = VIS.Utility.Util.getValueOfDecimal(mTab.getValue("VAT_HRA")); 

tds = VIS.Utility.Util.getValueOfDecimal(mTab.getValue("VAT_TDS")); 

pf = VIS.Utility.Util.getValueOfDecimal(mTab.getValue("VAT_PF")); 

this.log.fine("BasicSalary=" + basic + ", hra=" + hra + ", pf=" + pf); 

netsalary = basic + hra - (pf + tds); 

//Gross Salary include all 

gross = basic + hra + pf + tds; 

// var isSOTrx = (ctx.getWindowContext(windowNo, "IsSOTrx", true) == "Y"); 

mTab.setValue("VAT_NET", netsalary); 

mTab.setValue("VAT_Gross", gross);
 

} 

catch (err) { 

VIS.ADialog.info("error in NetSalary" + err, null, "", ""); 

this.setCalloutActive(false); 

return err; 

} 

this.setCalloutActive(false); 

ctx = windowNo = mTab = mField = value = oldValue = null; 

return""; 

}; 

//initialise model object in VAT 

VAT.Model = VAT.Model || {}; 

VAT.Model.CalloutEmployeeSalary = CalloutEmployeeSalary; //assign object in Model NameSpace 
 

/*********************** Second Callout Class CalloutDepartment*******************/ 

/** 

*Callout Class CalloutDepartment 

*must call this function 

*VIS.CalloutEngine.call(this, [className]); 

*/ 

function CalloutDepartment() { 

VIS.CalloutEngine.call(this, "VAT.CalloutDepartment"); //must call 

}; 

/** 

*Inherit CallourEngile Class  

*/ 

VIS.Utility.inheritPrototype(CalloutDepartment, VIS.CalloutEngine);//inherit CalloutEngine 

//Callout Method defined as Function prototype 

CalloutDepartment.prototype.showDepartmentCode = function (ctx, windowNo, mTab, mField, value, oldValue) { 

if (this.isCalloutActive() || value == null || value.toString() == "") { 

return""; 

} 

this.setCalloutActive(true); 

try { 

var departmentid=value; 

$.ajax({ 

url: VIS.Application.contextUrl + "VAT/Callout/GetDepartmentCode", 

data: { depID: departmentid }, 

success: function (result) { 

if (result) { 

mTab.setValue("VAT_DepartmentCode", result); 

} 

self.setCalloutActive(false); 

ctx = windowNo = mTab = mField = value = oldValue = null; 

}, 

error: function (eror) { 

self.setCalloutActive(false); 

console.log(eror); 

self.log.severe(eror.toString()); 

ctx = windowNo = mTab = mField = value = oldValue = null; 

} 

}); 

} // re-read customer rules 

catch(err) 

{ 

this.setCalloutActive(false); 

this.log.severe(err.toString()); 

} 

this.setCalloutActive(false); 

ctx = windowNo = mTab = mField = value = oldValue = null; 

return""; 

}; 

//initialise model object in VAT 

VAT.Model = VAT.Model || {}; 

VAT.Model.CalloutDepartment = CalloutDepartment; //assign object in Model NameSpace 
 

})(VAT, jQuery); 

In the above example there are two callout classes and both have one callout methods.  

In the first callout method we calculate the Gross Amount of employee and then set gross amount to Gross Field. 

In the second callout method we execute database query and set Department code on Employee window corresponding to selected department.
