In this example if the user copy-paste a value in an input field where the class contains 'price', the input is filtered except for decimals, dot, command and minus sign.
function filterCopyPaste() {
$('input').bind("paste input", function(e) {
var element = this;
let className = $(this).attr('class');
if (className.includes('price')) {
setTimeout(function () {
let val = $(e.currentTarget).val();
val = val.replace(/[^\d.,-]/g, '');
$(element).val(val);
}, 0);
}
$(this).val(val);
});
}
setTimeout is required to prevent duplicate content in Safari.
Sometimes you need to call filterCopyPaste after adding dynamic content or add the onpaste attribute:
onpaste="filterCopyPaste()"
