This is where we will create a simple interface for our application. This code will a HTML form that we will be using to conversion. To create this simply copy and write it into your text editor, then save it as index.html.
Creating JavaScript Function
This is where the main function of the application is. This code will convert all the string value into JSON object button is clicked. To do this just copy and write these block of codes inside the text editor and save it as script.js.
In this code we first create two variables called obj and json, in objwe create json string then parse the string into a json object. After that we created a method that will hold a certain functions. We first bind the form inputs and then contain them into a variable called str. Next we push all the string into the json object, and then use json.stringify().
Output:
The How to Convert String Value to JSON Object source code that I provide can be download below. Please kindly click the download button.
There you have it we successfully created How to Convert String Value to JSON Object. I hope that this simple tutorial help you to what you are looking for. For more updates and tutorials just kindly visit this site. Enjoy Coding!
