How Can I Highlight a Specific Word in Text Using jQuery?

Highlight a Word with jQuery

Question

Highlighting specific words in a block of text is a common task in web development. In this case, the goal is to highlight the word "dolor" within a given text block.

Solution

jQuery provides a simple and effective way to achieve this using its built-in highlight() plugin. The following steps outline the solution:

1. Include the jQuery plugin: Ensure that the jQuery library and the highlight plugin are loaded onto your page.
2. Select the text block: Use jQuery to select the target text block where you want to highlight the word.
3. Highlight the word: Call the highlight() method on the text block, passing in the word you want to highlight. The plugin will wrap the specified word in a span element with a custom class, which can be styled to highlight it.

Here's an example code:

$(function() {
  // Select the text block
  var textBlock = $('#text-block');

  // Highlight the word "dolor"
  textBlock.highlight('dolor');
});

Other Methods

Note: While the highlight plugin is widely used and effective for this task, it's important to note that highlighting text can also be achieved using pure JavaScript or CSS techniques:

• Pure JavaScript: You can use the replace() or replaceWith() methods in conjunction with regular expressions to search for and replace the target word with a highlighted version.
• CSS: By applying CSS styles such as background-color or text-shadow to elements with specific classes, you can visually highlight text without the need for additional plugins or JavaScript code.
