问题描述

我收到此错误，不知道如何解决：

alpine.js:115 Alpine Error: "ReferenceError: Invalid left-hand side in assignment"

Expression: "getTasks() = rightSideOfExpression($event, getTasks())"
Element: <input class=​&quot;shadow appearance-none border rounded w-1/​3 py-2 px-2 my-1 mx-1 text-gray-700 leading-tight focus:​outline-none focus:​shadow-outline" id=​&quot;valorvenda" type=​&quot;text" placeholder=​&quot;Valor" autofocus x-ref=​&quot;valorvenda" @keydown.enter=​&quot;addTask($refs.valorvenda.id)​&quot;>​

解决方案

您可能打算比较而不是分配。更改=为==：

getTasks() == rightSideOfExpression($event, getTasks())
