Get/Set Lookup field value using JavaScript in Dynamics CRM/Dynamics 365 CE

Hi Everyone,

Sometimes, it is really good to keep required and repeated code handy. 

Here is the JavaScript code for getting and setting value from CRM/CE Lookupfield.

// Get the Lookup Value.

function getLookupDetails(executionContext) {

    var formContext = executionContext.getFormContext();

    var entityName, entityId, entityLabel, lookupFieldObject;

    lookupFieldObject = formContext.data.entity.attributes.get("parentcontactid");

    if (lookupFieldObject.getValue() != null) {

        entityId = lookupFieldObject.getValue()[0].id.slice(1, -1);

        entityName = lookupFieldObject.getValue()[0].entityType;

        entityLabel = lookupFieldObject.getValue()[0].name;

    }

}

// Set the Lookup Value.

function setLookupField(executionContext) {

    var formContext = executionContext.getFormContext();

    var lookupData = new Array();

    var lookupItem = new Object();

    lookupItem.id = "74a968c5-6505-ea11-a81e-000d3a300ec6";

    lookupItem.name = "Nancy";

    lookupItem.entityType = "contact";

    lookupData[0] = lookupItem;

    formContext.data.entity.attributes.get("parentcontactid").setValue(lookupData);

}

Hope this helps.

Happy 365'ing
