How to Prevent Page Refresh When Clicking Buttons Inside Forms?

Preventing Page Refresh when Clicking Buttons Inside Forms

In web development, it's often essential to have buttons within forms that trigger specific functions. However, a common issue encountered is that clicking these buttons can inadvertently cause the page to refresh. This can disrupt the user experience and reset any previous interactions.

Issue Description

When a button inside a form is clicked, the default behavior in most cases is to submit the form. This triggers the submission of data to the server, which, in turn, reloads the page. This unwanted refresh action can be problematic in scenarios where the function executed by the button is intended to update the current page's content without reloading it.

Solution

To prevent the page from refreshing when a button within a form is clicked, it's necessary to modify the button's type attribute. The type attribute determines the behavior of the button. By default, the type is set to "submit," which initiates form submission.

The solution lies in setting the type attribute to "button" instead. This indicates to the browser that the button's purpose is to trigger a JavaScript function rather than submitting the form.

<button name="data" type="button" onclick="getData()">Click</button>

In the above code, the "type" attribute has been explicitly set to "button," ensuring that the click event triggers the "getData()" function without causing form submission and page refresh.

By implementing this solution, you can effectively prevent the automatic page refresh when a button within a form is clicked. This enables you to execute custom functions without disrupting the current page's content.
