href onclick

Definition

Href onclick is an HTML method that allows developers to drive a page when a user clicks on an HTML element. It is an attribute attached to an HTML element that is activated when clicked.

So, to explain it simply: "href" in HTML stands for "Hyperlink-reference" and is what you normally use in a link tag (a tag) to refer to another page or resource. It looks something like this:

How href onclick works:

<a href="https://beispiel.de">Visit example.com</a>

Now, when you bring "onclick" into play, you add a JavaScript-function, which is executed as soon as someone clicks on the link. It will look like this:

<a href="https://beispiel.de" onclick="meineFunktion();">Visit example.com</a>

When someone clicks on this link, two things happen: First, the JavaScript-function "myFunction()" is executed, and secondly, the user is redirected to the specified URL forwarded. That sounds pretty cool, doesn't it?

But what if you do not immediately go to the specified URL want to be forwarded? Maybe you want to execute the forwarding only after the JavaScript-function is completed. Then you can replace the "href" with "javascript:void(0)" to prevent the link from going immediately to the specified URL leads:

<a href="javascript:void(0)" onclick="meineFunktion();">Visit example.com</a>

Now the redirection will not be executed until you have specified this in your JavaScript-function, for example like this:

function myFunction() {
  // Here you can write all the code that should happen before the redirect.
  window.location.href = 'https://beispiel.de';
}

In this case, the user would only be redirected to "example.com" after the "myFunction()" has been completely executed. In summary, "href" with "onclick" helps you to redirect to a URL with a JavaScript-function and thus have more control over the behavior of links.

Advantages

Href onclick provides developers with a flexible and cost-effective way to control a page. They don't have to write additional code to enable controlling the page, but can simply use the href attribute.
