To pass variables to a Handlebars partial in JavaScript, you typically need to register the partial with Handlebars and then use it in your templates while passing the variables as parameters.
To do this, we do the following steps:
1. Register the partial with Handlebars:
Define your partial and register it with Handlebars using Handlebars.registerPartial().
2. Pass variables to the partial:
When you include the partial in your main template, pass the variables as parameters.
Here’s an example:
HTML:
<!-- index.html -->
<!DOCTYPE html>
<html>
<head>
<title>Handlebars Partial Example</title>
<script src="https://cdnjs.cloudflare.com/ajax/libs/handlebars.js/4.7.7/handlebars.min.js"></script>
</head>
<body>
<div id="container"></div>
<script id="main-template" type="text/x-handlebars-template">
<h1>Main Template</h1>
{{> myPartial firstName lastName}}
</script>
<script>
// Step 1: Register the partial with Handlebars
Handlebars.registerPartial('myPartial', '{{firstName}} {{lastName}}');
// Step 2: Compile the main template
var source = document.getElementById('main-template').innerHTML;
var template = Handlebars.compile(source);
// Step 3: Render the template with data
var data = { firstName: 'John', lastName: 'Doe' };
var html = template(data);
// Step 4: Display the rendered HTML
document.getElementById('container').innerHTML = html;
</script>
</body>
</html>
In this example, we define a main template containing a Handlebars partial {{> myPartial firstName lastName}}.
We register the partial with Handlebars using Handlebars.registerPartial().
Next we compile the main template using Handlebars.compile() and render it with the provided data.
Then we pass firstName and lastName as parameters to the partial when including it in the main template.
Adjust the variable names, partial content, and template structure as needed for your specific use case.
