Want support in polkadot.js/api

Question

I am trying to call api.query.staking.erasTotalStake in polkadot.js.

Which value can be parameter? Docs says u32. Is it block height?

https://codesandbox.io/s/keen-leakey-6jzrz9?file=/index.js This is my working code sandbox, I am just getting response 0.

How can I get another response beyond 0, and check if this api works correctly?

The parameter is the era you want to query.
The current value is 3728.

Hope it helps.

Hi. Thanks for your comment. I was able to get response. One more question. How can I get human readable value from response? I am getting <BN: 4f56b6cd0ff56b83>

You can use toString(), toHuman() or toBigInt() to get a more friendly value. More info at polkadot.js.org/docs/api/start/types.basics

Hi, I am trying api.query.staking.eraStakers on polkadot.js.org/apps/?rpc=wss%3A%2F%2Fkusama-rpc.polkadot.io#/… which you sent. However, I cannot select any AccountId32, or type. I can type era. How can I select account?

Not sure to understand what you are trying to do. From the polkadiot.js.org/apps, you need to enable the include option option, then slect/type an account address. For example, era 3728 and account JCghFN7mD4ETKzMbvSVmMMPwWutJGk6Bm1yKWk8Z9KhPGeZ are valid inputs.
