Basic Example

Using collectChange

export default class Plugin {
    apply() {
        return [{
            event: 'form.change.end',
            functional: this.formChangeEnd.bind(this)
        }]
    }
  	// If this is a middleware plugin in a vcrm project, swap the interaction parameter positions
    // formChangeEnd(plugin, context)
    formChangeEnd(context, plugin) {
      	return new Promise((resolve, reject) => {
         const dataChangeInfo = context.collectChange();
      	  console.log(dataChangeInfo.masterUpdate);
         console.log(dataChangeInfo.mdAdd);

          // check whether the change was triggered by manually editing the name field
          if(dataChangeInfo.blurField == 'name') {
               // modify a main-object field value
          	  context.dataUpdater.updateMaster({field_9sIuj__c: 100});

          	  // after modifying a field value, calculations and events usually need to be triggered
          	  context.triggerCalAndUIEvent({changeFields: ['field_9sIuj__c']}).then(rst => {
                if(rst.statusCode) { // calculation failed
                  reject();
                 } else {
                   resolve();
                 }
             })
          } else if(dataChangeInfo.masterUpdate.field_Z13mQ__c !== void 0) {
            // check whether the current change contains changes to a specific field
            context.dataUpdater.updateMaster({name: 'test'});

            context.triggerCalAndUIEvent({changeFields: ['name']}).then(rst => {
              if(rst.statusCode) { // calculation failed
                reject();
              } else {
                resolve();
              }
            })
          }
        })
