How to save form data in html using javascript
|
I am sharing a simple example here today that explains how easily you can save your form data in a text file or in a .txt file using JavaScript. Show A web form usually has many different elements, mostly input fields. You can extract data from these elements and save it in a database like SQL Server, or simply convert it into a JSON file. You can even save your form data in a text file. Let’s see the example first.
Try it Please do not get overwhelmed by the size of the program. The code inside the Once I have created the link, I’ll assign the BLOB object as the href (or as the URL) to the newly created Link tag. if (window.webkitURL != null) {
newLink.href = window.webkitURL.createObjectURL(textToBLOB);
}
else {
newLink.href = window.URL.createObjectURL(textToBLOB);
newLink.style.display = "none";
document.body.appendChild(newLink);
}👉 Now, you can also convert your Form data into PDF using JavaScript.
 BLOB stands for Binary Large Object. BLOBs are typically, images and audio files, which are converted into Binary and are later stored in a database. Using the Blob() constructor, I can convert ordinary texts into Blob objects. You can see the BLOB value (attached to the link’s URL or tag that we created in our script) in your browser’s console window. For example, if (window.webkitURL != null) {
newLink.href = window.webkitURL.createObjectURL(textToBLOB);
console.log (newLink);
}image The image shows the tag with URL having the blob value. In the console window, copy the URL and paste it in the browser’s address bar. The browser will translate the BLOB and will show the value. Remember: Every time you click the save button, the script will create a new BLOB from the form data. The final line of code, simply calls the click event of the tag and the browser downloads the file containing the data in your local hard disc. newLink.click(); 👉 Not just plain text, you can even convert an image into a PDF using only JavaScript.
