How to get the text of a specific option tag by value in jQuery?

Suppose I have a drop-down list like:

html
<select id='list'>
    <option value='1'>Option A</option>
    <option value='2'>Option B</option>
    <option value='3'>Option C</option>
</select>

Given the value ‘2’ (i.e., using a specific value, not necessarily the selected one), what selector can I use to get “Option B”?

I tried $("#list[value='2']").text();, but it is not working.

To get the text of a specific option tag by value in jQuery, you need to target the option element within the select element, not the select element itself. The correct selector is $("#list option[value='2']").text();.

Contents

Basic Solution

The correct way to get the text of a specific option by value is:

javascript
var optionText = $("#list option[value='2']").text();
console.log(optionText); // Output: "Option B"

This selector $("#list option[value='2']") finds the option element within the select with id “list” that has a value attribute equal to “2”, and then the text() method retrieves the text content of that element.

Understanding the Selector Syntax

The selector works by combining multiple parts:

  1. $("#list") - Selects the select element with id “list”
  2. option - Narrows down to option elements within that select
  3. [value='2'] - Filters options to only those with value attribute equal to “2”

According to the w3resource jQuery documentation, this approach allows you to “find the specific option tag text value” by using the attribute selector on the option elements.

Alternative Approaches

Using the :has() selector (jQuery 1.4+)

javascript
var optionText = $("#list:has(option[value='2']) option[value='2']").text();

Using filter() method

javascript
var optionText = $("#list option").filter(function() {
    return $(this).val() === '2';
}).text();

Using each() to find the option

javascript
var optionText = '';
$("#list option").each(function() {
    if ($(this).val() === '2') {
        optionText = $(this).text();
        return false; // Exit the loop once found
    }
});

Common Mistakes and Fixes

Mistake: Targeting the select element instead of options

Incorrect: $("#list[value='2']").text();

This tries to find a select element with id “list” that has a value attribute of “2”, which doesn’t make sense since select elements don’t have a value attribute in this context.

Fix: Always target the options within the select: $("#list option[value='2']").text();

Mistake: Missing quotes around attribute values

Incorrect: $("#list option[value=2]").text();

While this might work for numeric values without quotes, it’s better practice to use quotes for attribute selectors.

Better: $("#list option[value='2']").text();

Mistake: Using .val() instead of .text()

Incorrect: $("#list option[value='2']").val();

This would return “2” (the value attribute) rather than “Option B” (the text content).

Complete Working Example

Here’s a complete HTML page demonstrating the solution:

html
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="utf-8">
    <title>jQuery Get Option Text by Value</title>
    <script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>
</head>
<body>
    <select id='list'>
        <option value='1'>Option A</option>
        <option value='2'>Option B</option>
        <option value='3'>Option C</option>
    </select>
    
    <button id="getTextBtn">Get Text for Value 2</button>
    <div id="result"></div>
    
    <script>
        $(document).ready(function() {
            // Method 1: Direct selector approach
            $("#getTextBtn").click(function() {
                var optionText = $("#list option[value='2']").text();
                $("#result").text("Text for value '2': " + optionText);
            });
            
            // Method 2: Using filter (alternative approach)
            var optionText2 = $("#list option").filter(function() {
                return $(this).val() === '2';
            }).text();
            
            console.log("Alternative method result:", optionText2);
        });
    </script>
</body>
</html>

As explained in the GeeksforGeeks tutorial, jQuery allows you to select specific elements using its selectors, making it easy to target options by their value attributes.

Handling Dynamic Scenarios

When working with dynamically generated content, you need to ensure the elements exist before trying to access them:

javascript
// Wait for document ready or use event delegation
$(document).ready(function() {
    // Check if the element exists first
    if ($("#list option[value='2']").length > 0) {
        var optionText = $("#list option[value='2']").text();
        console.log(optionText);
    } else {
        console.log("Option with value '2' not found");
    }
});

// Or use event delegation for dynamic content
$(document).on('click', '#getTextBtn', function() {
    var optionText = $("#list option[value='2']").text();
    // Handle the result
});

Best Practices

  1. Always use quotes in attribute selectors: [value='2'] rather than [value=2]

  2. Check for existence before accessing:

    javascript
    if ($("#list option[value='2']").length > 0) {
    // Safe to use
}

  3. Cache your selectors when using them multiple times:

    javascript
    var $option = $("#list option[value='2']");
if ($option.length > 0) {
    var text = $option.text();
    var value = $option.val();
}

  4. Consider case sensitivity if values might vary in case:

    javascript
    $("#list option[value='2 i']").text(); // Case-sensitive
// For case-insensitive:
$("#list option").filter(function() {
    return $(this).val().toLowerCase() === '2'.toLowerCase();
}).text();

  5. Use specific selectors rather than generic ones for better performance.

The jQuery Learning Center emphasizes understanding the difference between selected options and specific options, which is crucial for working with dropdown menus effectively.

Conclusion

Getting the text of a specific option by value in jQuery is straightforward once you understand the proper selector syntax. The key points to remember are:

  1. Use $("#list option[value='2']").text(); to get the text content
  2. Target the options within the select, not the select itself
  3. Always use quotes around attribute values in selectors
  4. Check for element existence before accessing properties
  5. Consider caching selectors when using them multiple times

This approach works for both static and dynamically generated content, providing a reliable way to extract option text based on their values in jQuery.
