javascript - How to get reference to a react componenet in its container? -


i have container liked component. when onregionschange runs, need call function of map. how achieve it?

import { connect } 'react-redux' import map './map' import { setregion } './mapactions'  const map = state => {   return state.mapreducer.map.data }  const getregions = state => {   return state.mapreducer.map.data.regions }  const gettypes = state => {   return state.mapreducer.map.data.types }  const geo = state => {   return state.mapreducer.map.app.geo }  const mapstatetoprops = (state) => {   return {     geo: geo(state),     map: map(state),     regions: getregions(state),     types: gettypes(state)   } } const mapdispatchtoprops = (dispatch, ownprops) => {   return {     onregionschange: (region) => {       console.log('onregionschange')       dispatch(setregion(region))     },     ontypeschange: (navigation) => {       console.log('ontypeschange')     }   } }  const mapcontainer = connect(   mapstatetoprops,   mapdispatchtoprops )(map)  export default mapcontainer

notes: cannot reference getwrappedinstance

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
