HTML模板-填充特定数据

Question

Hi guys I need to make a template html file and change specific data in it. I've been searching how to do so and all I found was this:

    <div w3-include-html="tmp1.html"></div> 
<script>
function includeHTML() {
var z, i, elmnt, file, xhttp;
/*loop through a collection of all HTML elements:*/
z = document.getElementsByTagName("*");
for (i = 0; i < z.length; i++) {
elmnt = z[i];
/*search for elements with a certain atrribute:*/
file = elmnt.getAttribute("w3-include-html");
if (file) {
  /*make an HTTP request using the attribute value as the file name:*/
  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.";}
      /*remove the attribute, and call this function once more:*/
      elmnt.removeAttribute("w3-include-html");
      includeHTML();
    }
  }
  xhttp.open("GET", file, true);
  xhttp.send();
  /*exit the function:*/
  return;
}

} }

But this code just copy tmp1.html and I am unable to change specific data of the file without changing the file. Does it possible to do so? Sorry if it's have been asked before...

Answer 1

You're using a simple include system and not a template system.

Use a proper template system instead. There are many for JavaScript including Nunjucks which would let you do something like:

var html = nunjucks.render('tmp1.html', { foo: 'bar' });
document.body.insertAdjacentHTML('beforeend', html);

with a template like:

<div>My data is: {{foo}}</div>
