Window Open And Pass Parameters By Post Method

When it comes to web development, passing parameters between windows is a common task, especially when using the post method. In this article, we'll dive into how you can open a new window and pass parameters using the post method in your web application.

To achieve this, we'll first focus on opening a new window using JavaScript. You can do this by using the `window.open()` method, which allows you to specify the URL of the new window and other optional parameters. Here's a basic example:

let url = 'https://www.example.com'; 
let params = 'scrollbars=yes,location=yes,toolbar=no'; 

window.open(url, '_blank', params);

In this example, we're opening a new window to the specified URL with additional parameters such as scrollbars, location, and toolbar.

Next, let's explore how you can pass parameters using the post method. When you submit a form using the post method, the form data is sent in the request body instead of as part of the URL. This makes it suitable for passing sensitive or large amounts of data securely. Here's how you can achieve this:

In this form, we've set the method attribute to post and added hidden input fields to hold the parameters you want to pass. When the form is submitted, the data will be sent to the specified URL using the post method.

Now, let's tie it all together. To open a new window and pass parameters using the post method, you can combine the window.open() method with dynamically submitting a form. Here's how you can do it:

let url = 'https://www.example.com'; 

let params = 'scrollbars=yes,location=yes,toolbar=no';
let windowRef = window.open('', '_blank', params);

let form = document.createElement('form');
form.setAttribute('method', 'post');
form.setAttribute('action', url);
form.setAttribute('target', '_blank');

let param1 = document.createElement('input');
param1.setAttribute('type', 'hidden');
param1.setAttribute('name', 'param1');
param1.setAttribute('value', 'value1');
form.appendChild(param1);

let param2 = document.createElement('input');
param2.setAttribute('type', 'hidden');
param2.setAttribute('name', 'param2');
param2.setAttribute('value', 'value2');
form.appendChild(param2);

windowRef.document.body.appendChild(form);
form.submit();

In this example, we're creating a new form dynamically, setting it to post and the desired action URL, adding hidden input fields for the parameters, and submitting the form to open the new window with the parameters passed using the post method.

By following these steps, you can open a new window and pass parameters using the post method in your web application. Experiment with different scenarios and customize the code to fit your specific use case. Happy coding!
