Hey everyone, I’m new to web development and I’m stuck on a problem. I’ve built a form that should calculate the volume and cost of several planter types. When users submit the form, it should display the information they entered along with the calculated results, but nothing shows up.
Here’s an example of my simplified code:
<form onsubmit="return validateForm()">
<input type="radio" name="planterType" value="10" onchange="updateFields(this.value)">
<input type="text" id="length">
<input type="text" id="width">
<input type="submit" onclick="processForm()">
</form>
<div id="output"></div>
function processForm() {
let volume = calculateVolume();
let total = calculateTotal(volume);
let info = getFormInfo();
document.getElementById("output").innerHTML = info + volume + total;
}
Can anyone help me identify the issue? Thanks for your support!
hey jackhero77, i think the problem might be ur form’s onsubmit. it’s returning false which stops the form from submitting n ur processForm() function from running. try removing the return statement or use event.preventDefault() in validateForm() instead. hope this helps!
I’ve dealt with similar frustrations when starting out. One thing to check is whether your JavaScript is actually running. Try adding console.log() statements in your functions to see if they’re being called.
Also, make sure your script is properly linked in your HTML file. Sometimes the issue is as simple as a misplaced tag or incorrect file path.
Another potential problem could be that your calculateVolume(), calculateTotal(), and getFormInfo() functions aren’t defined or aren’t returning the expected values. Double-check these functions to ensure they’re working correctly.
Lastly, consider using event listeners instead of inline event attributes. It’s generally considered a better practice and might help isolate the issue:
document.querySelector(‘form’).addEventListener(‘submit’, function(e) {
e.preventDefault();
processForm();
});
Keep at it - debugging is a crucial skill to develop!
I’ve encountered a similar issue before. The problem likely lies in the form submission process. Your ‘processForm()’ function is called on the submit button’s ‘onclick’ event, but the form’s default submission behavior might be interfering. To resolve this, you could prevent the default form submission and handle it manually. Try modifying your HTML and JavaScript like this:
<form id="planterForm">
<!-- Your form inputs here -->
<input type="submit" value="Submit">
</form>
document.getElementById('planterForm').addEventListener('submit', function(e) {
e.preventDefault();
processForm();
});
This approach ensures that your ‘processForm()’ function runs when the form is submitted, without being overridden by the default form behavior. Let me know if this solves your problem!
