reactjs - Bind action parameters in mapDispatchToProps -


i have submit button dispatch action. action's payload post data sent api. use bindactioncreators in mapdispatchtoprops:

const mapdispatchtoprops = (dispatch) => ({     actions:  bindactioncreators(formactions, dispatch) });

then in component bind onclick submit action: 

<input type="submit" onclick={() => this.props.actions.submit(this.props.postdata)} />

i don't have give component post data in mapstatetoprops. i'd prefer give component action has post data binded submit function it's usage this:

<input type="submit" onclick={this.props.submit} />

is possible? don't have access state in mapdispatchtoprops

there third argument called mergeprops in connect method of react-redux supposed used in cases 1 described. in case can like:

const mapstatetoprops = state => ({ postdata: ... });  const mapdispatchtoprops = (dispatch) => ({   actions:  bindactioncreators(formactions, dispatch) });  const mergeprops = (stateprops, dispatchprops) => ({   submit: () => dispatchprops.actions.submit(stateprops.postdata), });  const connectedcomponent = connect(mapstatetoprops, mapdispatchtoprops, mergeprops)(component);

note component not receive actions nor postdata, submit.

is possible retrieve eta google's distancematrix api (or alternative api). fyi, eta different duration, when using public transport. following example clarify request. when leave on friday @ 8.15 i'll able catch train @ 8.30 , arrive @ 9.00 am. google says duration 30 minutes. however, when leave on saturday @ 8.15 i'll able catch first train @ 9.00 , arrive @ 9.30 am. google still says duration 30 minutes, means ignore delay. google map supports functionality there api around giving me eta instead of duration. can see, distance-matrix' response no good. clarifying question little. eta estimated time of arrival , it's clear user wants know entire duration of transport (including waiting time public transport).
