How to write programs on our website and redirect it to JDoodle online compiler?

While developing a website and we want to put a section where a user can write a program. JDoodle can be used to implement the feature on your website. A user can write programs in any of the programming languages and it can be redirected to JDoodle in order to execute the program.

Remember, it is not necessary to sign in or register in JDoodle for using this feature.

To perform the mentioned process a form, a textarea and a submit button is needed to be used. The action attribute of the form can be used to redirect the page to the required programming language compiler. The textarea will be used to allow the user to write the program and the submit button will redirect to the respective programming language online compiler. On the redirected page, we can easily run our program in the JDoodle compiler.

Steps to be followed:

Step 1: Open the jdoodle.com on the browser and select the programming language as Java.

Step 2: Copy the last part of the URL of the compiler page that is opened. The compiler URL will be used to redirect our code.

Step 3: Using the below code that contains all the components that are necessary to redirect the page to JDoodle. The action attribute is defined with the redirect API URL of JDoodle and the end of the URL copied from above is used with it. It will be helping to redirect the page whenever the form is submitted using the button.
