How Can I Hide and Show HTML Elements Using JavaScript?

How to Hide Elements in JavaScript

Hiding elements on a web page can enhance user experience and improve the visual appeal of your site. One effective way to do this in JavaScript is by leveraging the display style property.

Hiding an Element After Interaction

Consider the scenario where you have an "Edit" link that, when clicked, should display an editable textarea. Additionally, you want to hide the placeholder text ("Lorem ipsum") once the user begins editing. You can achieve this by modifying the following JavaScript function:

function showStuff(id, text, btn) {
    document.getElementById(id).style.display = 'block';
    // hide the lorem ipsum text
    document.getElementById(text).style.display = 'none';
    // hide the link
    btn.style.display = 'none';
}

Here's how it works:

• id is the ID of the element you want to make visible (e.g., the textarea).
• text is the ID of the element you want to hide (e.g., the "Lorem ipsum" text).
• btn is a reference to the element that triggered the action (e.g., the "Edit" link).

So, when the "Edit" link is clicked, JavaScript finds the corresponding textarea and makes it visible. It also finds the placeholder text and hides it. Lastly, it hides the "Edit" link itself to prevent repeated editing actions.

Example Code

To implement this solution, you can use the modified HTML code below:

<td class="post">
    <a href="#" onclick="showStuff('answer1', 'text1', this); return false;">Edit</a>
    <span>

This example demonstrates how to hide the placeholder text and "Edit" link when the user clicks the "Edit" link. The result is a clean and intuitive editing interface for your web page.
