Java:在形成后,可以立即选择要素?
原标题:JavaScript: can t immediately select elements after creating them?

我的发言稿载有引起我问题的以下法典:

btn.addEventListener( click , ()=> {
  if (!gamePlay) {
    setup()
    let word=document.querySelectorAll( box )
    console.log(word)
    btn.classList.toggle( hidden )
    gamePlay=true
  }
})

在<代码>div所有要素均在<> 编号>>上设定之后,我试图以类别名称(. Box)选定这些要素,但该节的排位清单是空洞的排位清单(也见文)。

我假定该法典是同步的。 我看不到打电话到<代码>setup()。

最佳回答

你们能够立即查阅和查阅文件内容。

这里的问题是,你选择的子公司是不正确的;用<条码>箱/代码”挑选内容。 班级,选择人“......”

btn.addEventListener( click , () => {

  if (!gamePlay) {

    setup();

    let word = document.querySelectorAll( .box ); // Prefix .
    console.log(word);
    btn.classList.toggle( hidden );

    gamePlay = true;
  }
})
