queryObject

The queryObject function parses a URL's query string into a structured JavaScript object. It supports nested objects, arrays, and automatic type conversion for numbers and booleans.

Examples

Basic Query Parsing

For a URL: https://example.com?page_id=12&active=true&category=books&token=8b3a2ca1fa73n31e

window.location.queryObject();
// Output: { page_id: 12, active: true, category: "books",token:"8b3a2ca1fa73n31e" }

Nested Query Keys

For a URL: https://example.com?user.name=John&user.age=30

window.location.queryObject();
// Output: { user: { name: 'John', age: 30 } }

Array Values

For a URL: https://example.com?tags[]=js&tags[]=html&tags[]=css

window.location.queryObject();
// Output: { tags: ['js', 'html', 'css'] }

Combination of Nested and Arrays

For a URL: https://example.com?user.hobbies[]=coding&user.hobbies[]=reading

window.location.queryObject();
// Output: { user: { hobbies: ['coding', 'reading'] } }

Malformed Query Handling

For a URL: https://example.com?valid=true&malformed%

window.location.queryObject();
// Output: { valid: true }
// Logs: Malformed query string pair detected: "malformed%". It has been skipped.

Key Features

1. Automatic Type Conversion: Converts numbers (123 → 123), booleans (true → true), and retains strings.

2. Nested Key Support: Easily handles dot-separated keys (user.name).

3. Array Support: Recognizes keys ending with [] as arrays.

4. Graceful Degradation: Skips malformed query pairs with a warning.

Notes

• Returns null if the query string is empty.

• Highly customizable for various URL query formats.
