How can I write this in Jquery ?

Question

// Restricts input for the given textbox to the given inputFilter.
function setInputFilter(textbox, inputFilter) {
["input"].forEach(function(event) {
textbox.addEventListener(event, function() {
if (inputFilter(this.value)) {
this.oldValue = this.value;
} else {
this.value = "";
}
});
});
}

// Install input filters.
setInputFilter(document.getElementById("value_to_check"), function(value) {

return /^\d*[.]?\d*$/.test(value);

});
