How to get HTML form data as text and send to html2pdf?
html2pdf is a JavaScript package that allows developers to convert html to canvas, pdf, images, and more. It takes html as parameter and adds it to pdf or desired document. Additionally, it allows users to download the document after adding html content.
Here we will access the form and add it to the pdf using the html2pdf npm package. We will see different examples to add form data to pdf.
grammar
Users can follow the following syntax to send html form data as text and send it to html2pdf.
var element = document.getElementById('form');
html2pdf().from(element).save();
In the above syntax, we access the form using the id and add it to the pdf using the html2pdf() method.
Example 1 (Add entire form to pdf)
In the example below, we create the form and specify "from" as the id. Additionally, we have added some input elements to the form. In JavaScript, we access the form using its id and store it in the "element" variable.
After that, we use the html2pdf() method to add a form to the pdf. In the output, the user can observe that when they click on the submit button, it downloads the pdf with the form input tags and values.

<h3 id="Using-the-i-html-pdf-i-to-create-a-pdf-using-the-content-of-the-form"> Using the <i> html2pdf </i> to create a pdf using the content of the form </h3>
<!-- creating a sample form with 3 to 4 input fields with labels -->
<form id = "form">
<label for = "name"> Name: </label>
<input type = "text" id = "name" name = "name"> <br> <br>
<label for = "email"> Email: </label>
<input type = "email" id = "email" name = "email"> <br> <br>
<input type = "button" value = "Submit" onclick = "generatePDF()">
</form>
<script>
// function to generate a pdf from the form using html2pdf
function generatePDF() {
// get the form element
var element = document.getElementById('form');
// create a new pdf using the form element
html2pdf().from(element).save();
}
</script>
</body>
</html>
Example 2 (only add form content to pdf)
In the example below, we will add the content of the form to the PDF, rather than the entire form. We have created the form and added some input fields like in the first example.
In JavaScript, we use the id of each input to access its value. After that, we created a "div" element using JavaScript and added the form content to the HTML of the div element using the "innerHTML" attribute.
Next, we use the content of the div element to create the pdf.

<!-- creating a sample form with 3 to 4 input fields with labels -->
<form id = "form">
<label for = "name"> Name: </label>
<input type = "text" id = "name" name = "name"> <br> <br>
<label for = "comment"> Comment: </label>
<input type = "comment" id = "comment" name = "comment"> <br> <br>
<input type = "button" value = "Submit" onclick = "getContentInPDF()">
</form>
<script>
function getContentInPDF() {
// access form elements one by one
var name = document.getElementById('name').value;
var comment = document.getElementById('comment').value;
// create a single html element by adding form data
var element = document.createElement('div');
element.innerHTML = '<h1 id="Form-Data">Form Data</h1>' +
'<p>Name: ' + name + '</p>' +
'<p>Comment: ' + comment + '</p>';
// create a new pdf using the form element
html2pdf().from(element).save();
}
</script>
</body>
</html>
Users learned to use html2pdf to add form data to pdf. We just need to call the html2pdf() method and it will handle everything. In the first example we added the entire form with the input values in the pdf, in the second example we extracted the form data and added it to the pdf.

Use ddrescue to recover data on Linux
Mar 20, 2024 pm 01:37 PM
DDREASE is a tool for recovering data from file or block devices such as hard drives, SSDs, RAM disks, CDs, DVDs and USB storage devices. It copies data from one block device to another, leaving corrupted data blocks behind and moving only good data blocks. ddreasue is a powerful recovery tool that is fully automated as it does not require any interference during recovery operations. Additionally, thanks to the ddasue map file, it can be stopped and resumed at any time. Other key features of DDREASE are as follows: It does not overwrite recovered data but fills the gaps in case of iterative recovery. However, it can be truncated if the tool is instructed to do so explicitly. Recover data from multiple files or blocks to a single

Google is ecstatic: JAX performance surpasses Pytorch and TensorFlow! It may become the fastest choice for GPU inference training
Apr 01, 2024 pm 07:46 PM
The performance of JAX, promoted by Google, has surpassed that of Pytorch and TensorFlow in recent benchmark tests, ranking first in 7 indicators. And the test was not done on the TPU with the best JAX performance. Although among developers, Pytorch is still more popular than Tensorflow. But in the future, perhaps more large models will be trained and run based on the JAX platform. Models Recently, the Keras team benchmarked three backends (TensorFlow, JAX, PyTorch) with the native PyTorch implementation and Keras2 with TensorFlow. First, they select a set of mainstream
The vitality of super intelligence awakens! But with the arrival of self-updating AI, mothers no longer have to worry about data bottlenecks
Apr 29, 2024 pm 06:55 PM
I cry to death. The world is madly building big models. The data on the Internet is not enough. It is not enough at all. The training model looks like "The Hunger Games", and AI researchers around the world are worrying about how to feed these data voracious eaters. This problem is particularly prominent in multi-modal tasks. At a time when nothing could be done, a start-up team from the Department of Renmin University of China used its own new model to become the first in China to make "model-generated data feed itself" a reality. Moreover, it is a two-pronged approach on the understanding side and the generation side. Both sides can generate high-quality, multi-modal new data and provide data feedback to the model itself. What is a model? Awaker 1.0, a large multi-modal model that just appeared on the Zhongguancun Forum. Who is the team? Sophon engine. Founded by Gao Yizhao, a doctoral student at Renmin University’s Hillhouse School of Artificial Intelligence.
