Extracting certain elements from a text: a beginner's guide

I am currently developing a task manager that includes a feature to generate a PDF file using jsPDF. I am facing the challenge of extracting specific attributes from a string in order to print them as text utilizing jsPDF.

The provided string is:

[{"content":"Test","category":"important","done":false,"createdAt":1659908150914},{"content":"Clean Room","category":"important","done":false,"createdAt":1659912937851}]

This task involves selectively capturing the values enclosed in quotes after the "content" attribute, such as "Test" and "Clean Room", and assigning separate IDs to each for printing purposes with jsPDF.

As a beginner on my first coding venture, I have been exploring different solutions but haven't found the optimal approach yet. Any suggestions or advice would be greatly appreciated!

javascript json parsing jspdf

Answer 1

Answer №1

To start, when dealing with a string that needs to be converted into a JSON object, use the JSON.parse() method. Here's an example:

var jsobj = JSON.parse('[{"content":"Test","category":"important","done":false,"createdAt":1659908150914},{"content":"Clean Room","category":"important","done":false,"createdAt":1659912937851}]');

Once you have the JSON object, access the content field like so:

jsobj.forEach(k => {
          
             console.log(k.content);

          });
