I have some inline javascript for using Signature Pad https://github.com/szimek/signature_pad It looks like this:
var signaturePad = new SignaturePad(canvas, {
backgroundColor: 'rgb(255, 255, 255)'
});
clearButton.addEventListener("click", function (event) {
signaturePad.clear();
});
And in the footer i have a separate file included click.js
$('.send-signature').on( 'click', function( event ) {
event.preventDefault();
console.log(event);
var $button = $(this);
$button.prop("disabled",true);
if (signaturePad.isEmpty()) {
alert("Please provide a signature first.");
return false;
}
} );
When I am clicking the button i get: Uncaught ReferenceError: signaturePad is not defined
If I click the clearbutton button, it works fine. I can't understand what the problem is and how i should pass the signaturePad to the click handler.
Click.js is included below the inline javascript.
I have tried a lot of different solutions but i think this is the furthest i have come. Can somebody point me in the right direction and say why this is not working?
You could save the signaturePad variable in the window object
window.signaturePad = new...
and then access it the same way
window.signaturePad.isEmpty()
this is not the most beautiful way of doing javascript, but I think it's OK for your purpose.
