How to Render A Plain Array With Mustache.js?

4 minutes read

To render a plain array with Mustache.js, you can pass the array as a context object when compiling the Mustache template. You can then use Mustache tags within the template to iterate over the array and render each element as needed. For example, if you have an array called "items" that you want to render, you can pass it as a context object like so:

1
2
3

var template = "{{#items}}<div>{{.}}</div>{{/items}}";
var data = { items: ["item1", "item2", "item3"] };
var html = Mustache.render(template, data);


This will iterate over the "items" array and render each element within a <div> tag. The resulting HTML will be assigned to the "html" variable, which you can then insert into your page as needed.


What is the recommended strategy for rendering large arrays with Mustache.js?

When rendering large arrays with Mustache.js, it is recommended to use pagination to limit the number of items displayed on the page at once. This can help improve performance and load times by only rendering a subset of the data at a time. Additionally, you can also implement lazy loading to only load additional data as needed, rather than all at once.


Another strategy is to use a virtual scrolling technique, where only the items that are currently in view are rendered, rather than rendering the entire array at once. This can help improve performance by reducing the number of elements in the DOM and only rendering what is visible to the user.


You can also consider optimizing your template rendering by pre-compiling your Mustache templates to reduce rendering time. This can be done using tools like Hogan.js, which compiles templates into JavaScript functions for faster rendering.


Overall, the key is to find the right balance between performance and usability when rendering large arrays with Mustache.js. Experiment with different techniques and optimizations to find the best solution for your specific use case.


How to display an array of links using Mustache.js?

To display an array of links using Mustache.js, you can follow these steps:

  1. Create an HTML template that contains the structure for displaying the links. For example:
1
2
3
4
5
6
7

<script id="link-template" type="text/template">
  <ul>
    {{#links}}
      <li><a href="{{url}}">{{title}}</a></li>
    {{/links}}
  </ul>
</script>


  1. Create a JavaScript object with the array of links you want to display. For example:
1
2
3
4
5
6
7

var data = {
  links: [
    { title: 'Google', url: 'https://www.google.com' },
    { title: 'Facebook', url: 'https://www.facebook.com' },
    { title: 'Twitter', url: 'https://www.twitter.com' }
  ]
};


  1. Compile the template and render it with the data using Mustache.js. For example:
1
2
3

var template = document.getElementById('link-template').innerHTML;
var rendered = Mustache.render(template, data);
document.getElementById('links-container').innerHTML = rendered;


  1. Add a container element in your HTML where the links will be displayed. For example:
1

<div id="links-container"></div>


When you run this code, Mustache.js will generate the HTML for the array of links and display them inside the links-container element. Each link will be displayed as a list item (<li>) with an anchor tag (<a>) that links to the specified URL.

<!DOCTYPE html>
<html>
<head>
  <title>Checkbox Array with Mustache.js</title>
</head>
<body>

<form action="/submit" method="post">
  <h2>Select your favorite fruits:</h2>
  <ul>
    {{#fruits}}
    <li>
      <input type="checkbox" name="fruits[]" value="{{value}}" id="{{id}}">
      <label for="{{id}}">{{name}}</label>
    </li>
    {{/fruits}}
  </ul>
  
  <button type="submit">Submit</button>
</form>

<script src="https://cdnjs.cloudflare.com/ajax/libs/mustache.js/4.2.0/mustache.min.js"></script>
<script>
  var fruits = [
    { name: 'Apple', value: 'apple', id: 'apple' },
    { name: 'Banana', value: 'banana', id: 'banana' },
    { name: 'Orange', value: 'orange', id: 'orange' }
  ];

  var template = document.querySelector('script[type="text/html"]').innerHTML;
  var rendered = Mustache.render(template, { fruits: fruits });
  document.body.innerHTML = rendered;
</script>

<script type="text/html">
{{#fruits}}
<li>
  <input type="checkbox" name="fruits[]" value="{{value}}" id="{{id}}">
  <label for="{{id}}">{{name}}</label>
</li>
{{/fruits}}
</script>

</body>
</html>


In this code, we define an array of fruits with their names, values, and unique IDs. We then use a Mustache template to iterate over the fruits array and generate checkboxes for each fruit. The rendered output is inserted into the body of the HTML document. When the form is submitted, the selected checkboxes will be sent as an array in the request data.


How to iterate through an array using Mustache.js?

To iterate through an array using Mustache.js, you can use the {{#each}} tag. Here is an example code snippet that demonstrates how to iterate through an array:

<!DOCTYPE html>
<html>
<head>
    <title>Mustache.js Array Iteration Example</title>
</head>
<body>
    <div id="content"></div>

    <script src="https://cdnjs.cloudflare.com/ajax/libs/mustache.js/4.1.0/mustache.min.js"></script>
    <script>
        var data = {
            items: ["Apple", "Banana", "Orange", "Grapes"]
        };

        var template = "{{#items}}<li>{{.}}</li>{{/items}}";

        var rendered = Mustache.render(template, data);
        document.getElementById('content').innerHTML = '<ul>' + rendered + '</ul>';
    </script>
</body>
</html>


In this example, we have an array of fruit items in the items property of the data object. We then define a template that uses the {{#each}} tag to iterate through each item in the items array and generate an <li> element for each item. Finally, we render the template using Mustache.js and insert the rendered HTML into the content element on the page.


When you run this code, you will see a list of fruit items displayed on the page, with each item in the array rendered as a list item.
