Is there a way to hide or show a field on my website based on the value in the shopping cart? I've created a function for this, but I'm struggling with the condition. Can you help me figure out how to write it correctly?
<script>
$(document).ready(function() {
function updateTextFieldVisibility() {
var textField = $('#grid-2');
if ($('#grid-12-12-12').val() > 0) {
textField.show();
} else {
textField.hide();
}
}
});
</script>
Can you tell if $('#grid-12-12-12') is an HTML Element? You can verify its value by using either .text() or the innerText property.
Another option to consider is utilizing a "MutationObserver" for detecting changes on elements in real-time instead of relying on setInterval method.
Check out this example:
function isElementEmpty(element) {
return +element.innerText
}
// Selecting the target element
const targetElement = document.getElementById('grid-12-12');
// Creating a Mutation Observer instance
const observer = new MutationObserver(function(mutations) {
mutations.forEach(function(mutation) {
if (isElementEmpty(targetElement)) {
// Hide the specified element
// ...
} else {
// Display the specified element
// ...
}
});
});
// Begin observing the target element
observer.observe(targetElement, {
childList: true
});
// To stop observing the element when necessary
// observer.disconnect();
