如何 - 包含 HTML


了解如何在 HTML 中包含 HTML 片段。


HTML

将要包含的 HTML 保存在 .html 文件中:

content.html

<a href="howto_google_maps.asp">Google Maps</a><br>
<a href="howto_css_animate_buttons.asp">Animated Buttons</a><br>
<a href="howto_css_modals.asp">Modal Boxes</a><br>
<a href="howto_js_animate.asp">Animations</a><br>
<a href="howto_js_progressbar.asp">Progress Bars</a><br>
<a href="howto_css_dropdown.asp">Hover Dropdowns</a><br>
<a href="howto_js_dropdown.asp">Click Dropdowns</a><br>
<a href="howto_css_table_responsive.asp">Responsive Tables</a><br>

包含 HTML

包含 HTML 是通过使用 w3-include-html 属性完成的:

实例

<div w3-include-html="content.html"></div>

添加 JavaScript

HTML 包含由 JavaScript 完成。

实例

<script>
function includeHTML() {
  var z, i, elmnt, file, xhttp;
  /* 循环遍历所有 HTML 元素的集合:*/
  z = document.getElementsByTagName("*");
  for (i = 0; i < z.length; i++) {
    elmnt = z[i];
    /*搜索具有特定属性的元素:*/
    file = elmnt.getAttribute("w3-include-html");
    if (file) {
      /* 使用属性值作为文件名发出 HTTP 请求:*/
      xhttp = new XMLHttpRequest();
      xhttp.onreadystatechange = function() {
        if (this.readyState == 4) {
          if (this.status == 200) {elmnt.innerHTML = this.responseText;}
          if (this.status == 404) {elmnt.innerHTML = "Page not found.";}
          /* 移除该属性,并再次调用此函数:*/
          elmnt.removeAttribute("w3-include-html");
          includeHTML();
        }
      }
      xhttp.open("GET", file, true);
      xhttp.send();
      /* 退出函数:*/
      return;
    }
  }
}
</script>

在页面底部调用 includeHTML():

实例

<script>
includeHTML();
</script>
