Question

我一直在这些论坛上四处寻找可以直接下载HTML页面的代码（例如，从其他按钮添加了元素，以及div中的所有内容），以便可以再次使用数据仍然存在。我一生都找不到下载该页面的任何内容。下面是我真正用来保存html文档的最接近的文档，即使（显然）该文档仅显示所写的文本。我可以对其进行编辑以使其封装整个页面吗？以很少的经验我只能道歉。

Answer 1

一种解决方案是FileSaver.js

遵循该页面上的示例，并为您的Blob使用document.innerHTML（我用过的东西）实际上，我忘记了是否不包括标题。如果是这样，我对此有一个解决方案（也在StackOverflow上），但我在本地没有代码可以查看如何解决此问题（如果确实这样做，则必须解决）

Answer 2

您可以尝试

<a href ="#" id="donwload-link" onClick="myFunction()">download html content</a>

<script>
function myFunction() {
  var content = document.documentElement.innerHTML;
  download(content, "index", "txt")

}
function download(content, fileName, fileType) {
  var link = document.getElementById("donwload-link");
  var file = new Blob([content], {type: fileType});
  var donwloadFile = fileName + "." + fileType;
  link.href = URL.createObjectURL(file);
  link.download = donwloadFile
}
</script>
