Why Doesn't My JavaScript Function Work When a Link is Clicked?

JavaScript function doesn't work when link is clicked

This issue arises when an inline event attribute (onclick) is used in an HTML hyperlink element.

Causes and Solutions:

1. Missing Function Invocation Parenthesis:

   The original code incorrectly omitted the parentheses after the function name in the inline event attribute:

   <a href="" onclick='getContent()'> LoremIpsum</a>

   This should be corrected to:

   <a href="" onclick='getContent()'> LoremIpsum</a>

2. Separation of Concerns Violation:

   Using inline event attributes blurs the line between HTML and JavaScript, making the code harder to maintain.

   Instead, separate the concerns by moving the event handling logic to an event listener attached using addEventListener():

   var btn = document.getElementById("btnChangeSrc");
   btn.addEventListener("click", getContent);

3. Empty Href Attribute:

   When using a hyperlink purely for triggering an event without navigation, the href attribute should be assigned a value of # to prevent the default browser behavior:

   <a href="#" onclick='getContent()'> LoremIpsum</a>

Alternatives to Hyperlinks for Button-Like Behavior:

Additionally, consider replacing the hyperlink with a designated button element for improved accessibility and flexibility:

<button>
