示例3: _onPageLoadInitFireAndForgetAsync
private async _onPageLoadInitFireAndForgetAsync() {
await utils.onPageLoadAsync(); // wait for page to load
// Hack: We need to know the networkId the injectedWeb3 is connected to (if it is defined) in
// order to properly instantiate the web3Wrapper. Since we must use the async call, we cannot
// retrieve it from within the web3Wrapper constructor. This is and should remain the only
// call to a web3 instance outside of web3Wrapper in the entire dapp.
// In addition, if the user has an injectedWeb3 instance that is disconnected from a backing
// Ethereum node, this call will throw. We need to handle this case gracefully
const injectedWeb3 = (window as any).web3;
let networkIdIfExists: number;

示例4: destroy
public destroy() {

}
示例5: updateWeb3WrapperPrevUserAddress
// HACK: When a user is using a Ledger, we simply dispatch the selected userAddress, which
// by-passes the web3Wrapper logic for updating the prevUserAddress. We therefore need to
// manually update it. This should only be called by the LedgerConfigDialog.
public updateWeb3WrapperPrevUserAddress(newUserAddress: string) {
this._blockchainWatcher.updatePrevUserAddress(newUserAddress);
