Script for editing page properties

Hi @darwin, I think using JS will not be the proper option. Groovy console as @jeevanraj suggest is the way to go. Below you can find simple groovy script that I believe do what you need.

import com.day.cq.wcm.msm.api.LiveRelationshipManager
import org.apache.sling.api.resource.ModifiableValueMap

// array of properties that should be changed
def propertyNames = ["jcr:title"] as String[]

// map of propertyName:newValue
def propertyValues = ["jcr:title":"new value"]

// array of page paths that should be changed
def pagePaths = ["/content/we-retail/us/en/men"] as String[]

def liveRelationshipManager = getService(LiveRelationshipManager.class)

pagePaths?.each { pagePath ->
    def pageResource = resourceResolver.getResource(pagePath)
    def liveRelationship = liveRelationshipManager.getLiveRelationship(pageResource, true)
    
    liveRelationshipManager.cancelPropertyRelationship(resourceResolver, liveRelationship, propertyNames, true)
    
    def jcrContentResource = resourceResolver.getResource(pageResource?.path + "/jcr:content")
    def valueMap = jcrContentResource?.adaptTo(ModifiableValueMap.class)
    
    println "Page has been updated ${pageResource?.path}"
    propertyNames?.each { property ->
        valueMap.put(property, propertyValues[property])
        println "Property has been changed ${property}"
    }
    resourceResolver.commit()
    
    // activating jcr:content because this is place where page properties are stored and this node has been changed
    activate(jcrContentResource?.path)
}
