🔍 Methods to Get Content in jQuery

Method	Description	Element Types
.html()	Gets the inner HTML	Any HTML element (e.g., <div>)
.text()	Gets only the plain text	Any HTML element
.val()	Gets the current value	Form fields (<input>, <select>, etc.)

---

🧪 Example 1 – Get Inner HTML Using .html()

<div id="description"><strong>Product details</strong></div>

<script>
  let htmlContent = $("#description").html();
  alert(htmlContent);
</script>

Explanation:

• $("#description"): Selects the <div> element
• .html(): Retrieves everything inside, including tags
• Result shown: <strong>Product details</strong>

✅ Use .html() when you want formatted content (including HTML tags).

---

🧪 Example 2 – Get Plain Text Using .text()

<p id="message">Welcome to <b>jQuery</b> tutorial!</p>

<script>
  let text = $("#message").text();
  console.log(text);
</script>

Explanation:

• .text() ignores HTML tags
• Output in console: Welcome to jQuery tutorial!
• It strips <b> and only shows the readable text

✅ Use .text() to extract clean text for logging, validation, or display.

---

🧪 Example 3 – Get Input Field Value Using .val()

<input type="text" id="username" value="John123">
<button id="getUser">Get Username</button>

<script>
  $("#getUser").click(function() {
    let user = $("#username").val();
    alert(user);
  });
</script>

Explanation:

• .val() fetches the current value from the input
• When button is clicked, it shows John123 (or whatever the user typed)

✅ Ideal for forms, surveys, login systems, and dynamic content entry.

🧠 Comparison Table

Use Case	Use This Method	Why?
Retrieve formatted HTML block	.html()	Keeps HTML tags intact
Get clean readable text	.text()	Strips out HTML, safer for display
Access user input	.val()	Fetches current value from input fields

---

⚠️ Common Pitfalls

Mistake	Tip
Using .val() on <div> or <p>	Only use .val() with form elements
Expecting .text() to preserve tags	Use .html() instead if you need inner markup
Reading before DOM is ready	Wrap code in $(document).ready() or after load

---

📘 Best Practices

📘 Use .text() when displaying user data to avoid XSS
💡 Avoid manipulating inner HTML with user-generated data
📘 Always check if the element exists before calling .val() or .html()

if ($("#output").length) {
  let val = $("#output").html();
}
