How to convert Title to URL Slug using JavaScript?
Overview
Convert headers to URL Slug Also known as "Slugify" headers. A URL slug is a title that is descriptive and easy to read. It is appended to the page's URL, which tells the story of the current page, because slugs are self-describing. Therefore, converting headers to slugs using JavaScript can be achieved using certain JavaScript functions such as toLowerCase(), replace(), trim().
algorithm
Step 1 - Create an HTML page containing two input tags and add id attributes as "title" and "urlSlug" respectively. The first input element will receive the The input user as title and another label will display the URL slug. Also create an HTML button "
Step 2 - Now create a "convert()" arrow function as the internal JavaScript of the HTML page.
convert=()=>{}
Step 3 - Access the value of the first input tag with id "document.getElementById("title")".value and store that value in a variable.
document.getElementById('title').value;
Step 4 - Convert the value received from the title to lowercase letters using the "toLowerCase()" function of the string. "t" is the variable that receives the title.
t.toLowerCase();
Step 5 - Now remove the leading and trailing spaces from the title using the "trim()" function.
t.trim();
Step 6 - Use the "replace()" function with a pattern to replace all spaces in the title with "-" dashes
title with “-” dash, using “replace()” function with a pattern t.replace(/[^a-z0-9]+/g, '-');
Step 7 - The URL Slug is ready and displayed on the browser screen.
document.getElementById('urlSlug').value = slug;
Example
In this example, we get the title from the user as input. When the user enters any title and clicks the button, the Convert() function is triggered, which changes the title value to lowercase and then changes all leading and trailing spaces of the title to lowercase. Then, in the given title, spaces will be replaced with dashes (-), and the URL slug will be displayed on the browser's read-only input tag.
<html lang="en">
<head>
<title>Convert title to URL Slug</title>
</head>
<body>
<h3>Title to URL Slug Conversion</h3>
<label>Title:</label>
<input type="text" id="title" value="" placeholder="Enter title here"> <br />
<label>URL Slug:</label>
<input type="text" id="urlSlug" style="margin:0.5rem 0;border-radius:5px;border:transparent;padding: 0.4rem;color: green;" placeholder="Slug will appear here..." readonly><br />
<button onclick="convert()" style="margin-top: 0.5rem;">Covert Now</button>
<script>
// This function converts the title to URL Slug
convert = () => {
var t = document.getElementById('title').value;
t = t.toLowerCase(); //t is the title received
t = t.trim(); // trim the spaces from start and end
var slug = t.replace(/[^a-z0-9]+/g, '-'); // replace all the spaces with "-"
document.getElementById('urlSlug').value = slug;
document.getElementById('urlSlug').style.border="0.1px solid green";
}
</script>
</body>
</html>
In the output of the above example, the title entered by the user is "Tutorial Point Article". After clicking "Convert Now", the title will be converted into a URL slug, i.e. "Tutorial Point Article". Which uses the trim() function to remove trailing spaces and replace them with hyphens.
in conclusion
Uniform Resource Locator (URL) slug helps improve the search ranking of your page. Therefore, the URL slug must be in the URL, and since all words in the URL are lowercase, the title is also converted to lowercase first. To watch out for slugs in URLs, just take any article, blog or any other content of the website and observe the endpoint of the URL, if it appears in the sentence then it will end up with the same as our example above.
