存储循环结果以推入HTML

编辑:已解决。在这里乐于助人的人帮我解决了这个问题之后,我意识到这个问题与我的工作有关 getElementsByClassName 选择器。抱歉,如果标题有误导性。原始问题如下。

我从这个函数的 for 循环,但我无法将它们打印到HTML。

任何建议都将不胜感激。

HTML格式:

<input type="text" name="searchString" class="searchString">

<span class="longestWordInput"></span>
<span class="longestWordCountInput"></span>

<button class="generate">Generate</button>

function longestWordFunc() {
  var stringSplit = document.querySelector(".searchString").value.split(" ");

  let longestWordCount = 0;
  let longestWord = "";

  for(var i = 0; i < stringSplit.length; i++) {
    if(stringSplit[i].length > longestWordCount) {

      longestWordCount = stringSplit[i].length; 
      longestWord = stringSplit[i]
    }
  }

  //Logging expected result
  console.log(longestWordCount)
  console.log(longestWord)

  //Print to HTML not working
  document.getElementsByClassName("longestWordInput").innerHTML = longestWord;
  document.getElementsByClassName("longestWordCountInput").innerHTML = longestWordCount;
};

document.querySelector(".generate").addEventListener("click", longestWordFunc);
