Code Sample for a Custom Button That Creates a Child Record

This following code sample creates a custom button labeled Create Task on the Opportunity Detail page. When the button is clicked, the REST API is used to create a child Activity record. In the createTask() function, you must replace <PodURL> with the URL for your pod. The Restful Services Integration privilege is required to send REST requests.

function createHttpRequest (httpmethod)

{

var xmlhttpRequest = null;

xmlhttpRequest = new XMLHttpRequest();

if (typeof xmlhttpRequest.overrideMimeType != 'undefined')

{

xmlhttpRequest.overrideMimeType('application/json');

}

return xmlhttpRequest;

}

oraclecrmod.onReady(function()

{

// when on the Opportunity Detail page

if(oraclecrmod.ctx.object == "Opportunity" && oraclecrmod.ctx.isDetailPage())

{

function createTask()

{

var id = oraclecrmod.getField("Id").getValue();

var insertPayload = "{\"Activities\":[ \

{ \

   \"Activity\": \"Appointment\", \

   \"Subject\": \"Opp Auto Appointment\", \

   \"Type\": \"Other\", \

   \"Location\": \"Markham\", \

   \"OpportunityId\":\"" + id + "\" \

} \

]}"

//Calls REST API to create Task

var url = "<PodURL>/OnDemand/user/Rest/026/Activities";

var req = createHttpRequest ("POST");

req.open('POST', url, false);

req.setRequestHeader("Content-Type","application/vnd.oracle.adf.resource+json");

req.send(insertPayload);

alert(req.responseText);

//success

if (req.readyState == 4 && req.status == 201)

{

   alert("success");

}

}

// get the title bar

titleBar = oraclecrmod.getTitleBar("OpportunityFormTB");

// create the new button

button = oraclecrmod.createButton({id:"CreateTaskButton", text:"Create Task",parent:titleBar});

// associate the createTask function with the button click event

button.on("click", createTask);

}

}

);
