How can I make the submit button invisible until a file is selected?
<form action="upload.php" method="POST" enctype="multipart/form-data">
<input type="file" name="imageURL[]" id="imageURL" />
<input type="submit" value="submit" name="submit" style="display: none;" id="submitButton"/>
</form>
To start, you can initially hide the submit button and then display it upon a change in the input type file.
Here is an example of how you can achieve this:
$("#imageURL").on("change", function(){
$("#submit").show();
})
I have created a JSFiddle using jQuery to demonstrate this.
I trust that this solution will be beneficial.
This solution offers a more efficient approach:
$('[type=submit]').hide();
setInterval(function(){
if($('#imageURL').val()!=""){
$('[type=submit]').show();
}else{
$('[type=submit]').hide();
}
},1000);
