This method is used to update main object data.

Parameters

Parameter	Description	Type
changeData	Field data to be changed	Object
options	Optional configuration parameters	Object

Description of the options parameter:

Parameter	Description	Type	Default
fieldName	Field that triggers the change; required to trigger UI events	String	—
triggerUiFieldNames	Fields that trigger UI event changes, used in scenarios where multiple fields are changed at the same time	String Array	—
triggerCal	Whether to trigger calculation	Boolean	true
triggerUi	Whether to trigger UI events	Boolean	true
noCalField	Specify main-object fields that should not trigger calculation	Array	—

Return Value

Promise, which asynchronously returns the result after calculations and UI events are completed.

Code Example

export default function (context) {
  return {
    /** After the create/edit page has finished rendering */
    renderEnd(){
        context.setData({"field_api_name": value}, {
      		fieldName: 'field_api_name'
  			}).then(()=>{
          console.log("context.setData success.")
        });
    }
  }
}

Notes

• Avoid calling context.setData frequently. Merge updates as much as possible and call it once.

  • setData may trigger asynchronous tasks such as calculations and UI events, and frequent calls may cause concurrency issues.
  • Frequent calls that trigger UI updates will affect performance and may cause page lag.

  let changeData = {k1:1,k2:2}
  // avoid calling inside loops
  // incorrect example
  Object.keys(changeData).forEach(k=>{
    context.setData({k: changeData[k]},{fieldName:k})
  })
  // correct example
  context.setData(changeData,{fieldName:"k1"})
