Solidity
來自第二種形式的輸入不會顯示
該項目是更改某人的名字，我有兩個名字的兩個表格。當我在solidity中執行程式碼時，我可以更改名稱，沒問題。當我用 ganache 執行它時，第二種形式的名稱更改永遠不會“佔用”。
堅固性
pragma solidity ^0.4.2; contract Election { string public candidateName; string public candidateotherName; function Election () public { candidateName = "Candidate 1"; candidateotherName = "Candidate2"; } function setCandidate (string _name) public { candidateName = _name; } function setOtherCandidate (string _othername) public { candidateotherName = _othername; } }html

contract.setOtherCandidate($('testid').val());到
contract.setOtherCandidate($('input').val());並更改輸入類型，更改所有變數的名稱，並嘗試
使用 # 引用 id 的東西。我無法在送出時更新第二個表單，我不知道為什麼，但仍然堅信這是由於底部附近的行需要將“testid”更改為其他內容。感謝您的任何幫助
如果有人偶然發現這一點，這就是我為解決這個問題所做的。我為每個“表單部分”（唯一的標題、表單名稱、id …）設置了唯一的每個名稱，然後引用了這些名稱。一些 id 不是唯一的。我還使用 # 來引用 id。
