javascript - 如何根据单击的图像更改文本段落

Question

我正在尝试根据单击的内容更改图像和段落。目前，图像会根据点击的内容进行更改，而不是段落。我在使文本与图像相对应时遇到了一些麻烦。我是编程新手，所以如果你们有任何帮助的想法。谢谢，如果你们需要更多信息，请告诉我。

function myFunction(imgs) {
   var expandImg = document.getElementById("expandedImg");
   var imgParagraph = document.getElementById('img-paragraph');
   expandImg.src = imgs.src;

   // use 'display:table-cell' to keep elements side-by-side
   expandImg.parentElement.style.display = "table-cell";
   imgParagraph.style.display = 'table-cell';
 }

让我们为每个名为 的图像添加一个自定义属性parag，然后我们可以使用此属性的值设置为img-paragraph：

function myFunction(imgs) {
   var expandImg = document.getElementById("expandedImg");
   expandImg.src = imgs.src;
   var imgParagraph = document.getElementById('img-paragraph');
   imgParagraph.innerHTML = imgs.getAttribute("parag");

   expandImg.parentElement.style.display = "table-cell";
   imgParagraph.style.display = 'table-cell';
}

@font-face {
  font-family: 'futuralight';
  src: url('../Fonts/Futura Light/futura_light_regular-webfont.woff2') format('woff2'), url('../Fonts/Futura Light/futura_light_regular-webfont.woff') format('woff');
  font-weight: normal;
  font-style: normal;
}

@font-face {

  src: url('../Fonts/Teko/teko-regular-webfont.woff2') format('woff2'), url('../Fonts/Teko/teko-regular-webfont.woff') format('woff');
  font-weight: normal;
  font-style: normal;
}
