TLDR

Here's a quick method to perform a POST redirect using jQuery by constructing a hidden form and submitting it automatically:

var post_data = { key1: 'value1', key2: 'value2' }; // Your "magic" POST data var form = $('<form>').attr({ action: 'your_target_url', method: 'POST' }).appendTo('body'); $.each(post_data, (k, v) => $('<input>').attr({ type: 'hidden', name: k, value: v }).appendTo(form)); form.submit(); // And... it's off to the races!

This code snippet creates a "stealthy" form on the sly, fills it with your POST data, and fires off the submission, triggering a redirect to your desired destination.

Usage of $.extend for custom jQuery function

Why write repetitive code when jQuery's $.extend allows you to combine objects and create your own custom redirection function? Let code reusability be your mantra!

$.extend({ redirectPost: function(location, args) { // create a "spy" form let form = $('<form>').attr({ method: 'POST', action: location }); // add the "secret" data $.each(args, function(key, value) { $('<input>').attr({ type: 'hidden', name: key, value: value }).appendTo(form); }); // attach the form to the DOM and submit form.appendTo('body').submit(); } });

Now, you can use $.redirectPost('your_target_url', post_data); for a clean and efficient redirect carrying all your "top-secret" POST data!

Post-Redirect potential pitfalls: Edge cases and solutions

Size does matter: Handling large datasets

Beware of the limits! If you are dealing with heavy data, check your server's maximum POST size and consider chunking the data if necessary.

Security? That's not a joke

Humor aside, there's no kidding about security. Always sanitize and validate POST data server-side to evade those pesky injection attacks.

Multipart: When files are involved

Trying to include files in your POST-data bash? Employ type="file" for your input fields and remember to set enctype to multipart/form-data in your form. File POSTing: Unlocked!

Deep dive: Enhancing the redirect pattern

Clean after you: Removing the form post submission

To prevent DOM clutter after the great escape (form submission), ensure to clean up with the remove function like a responsible coder:

form.submit().remove(); // Bye form, it was nice knowing you!

Compatibility: New isn't always better

When using plugins like jquery.redirect.js, ensure they are friends with your jQuery version. Version conflicts - not on my watch!

Time is money: Strive for efficiency

Favor efficient solutions - Plugins can save you a ton of time and resource by reusing proven mechanisms.

Practicality: Custom tailored suits best

Evaluate the practicality of your solution based on your specific scenario and server configurations. Remember, one size does not fit all!
