Drizzle 状态

  accounts: [],
  contracts: {
    contractName: {
      callerFunctionName: {
        argsHash: {
  transactions: {
    txHash: {
  drizzleStatus: {
  web3: {

 accounts (array数组)


 contracts (object对象)

一系列只能合约对象哈希表, 以ABI中定义的智能合约名为key.

 contractName (object对象)

initialized (boolean): true 是否实例化了, 当智能合约完全实例化后置位真 synced (boolean): false 当区块中智能合约状态变化后, Drizzle正在重新运行的时候为false

events (array): 事件的列表, Drizzle只会监听在options中定义的事件

and contain the outputs indexed by a hash of the arguments passed during the call (argsHash). If no arguments were passed, the hash is 0x0. Drizzle reads from the store for you, so it should be unnecessary to touch this data cache manually. 合约状态也包含调用(call on)本合约的其他所有合约(callerFunctionName)的状态, 以名称先后排序

args (array): Arguments passed to function call. value (mixed): Value returned from function call.

 transactions (object)

A series of transaction objects, indexed by transaction hash.

 txHash (object)

confirmations (array): After the initial receipt, further confirmation receipts (up to the 24th). error (object): contains the returned error if any. receipt (object): contains the first transaction receipt received from a transaction's success event.

status (string): true or false depending on transaction status

  • pending when the transaction has broadcasted successfully, but is not yet mined
  • success when a transaction receipt has been received (you may also wish to check for further confirmations)
  • error if any errors occurred after broadcasting

 transactionStack (array)

In some cases, a transaction may be malformed and not even make it to being broadcasted. To keep track of this, an empty string will be added to this array and replaced with the transaction hash once broascasted. The cacheSend() method will return a stackId, which will allow you to observe this process for your own transaction status indicator UI.

 drizzleStatus (object)

An object containing information about the status of Drizzle.

initialized (boolean): true once:

  • web3 is found or instantiated
  • Account addresses are stored in state
  • All contracts are instantiated

 initialized (boolean)

false by default, becomes true once a web3 instance is found and the accounts and contracts are fetched.

 web3 (object)

status (string): initializing, initialized and failed are possible options. Useful for triggering warnings if web3 fails to instantiate.
