jquery - Need helping passing javascript variable through hidden form input -
okay, have javascript calculate dynamic price html form. code follows:
jquery("input[name='amount']").change(function() { if (isnan(parsefloat(this.value)) || !isfinite(this.value)) { jquery(this).val(''); return false; } var calc = parsefloat(this.value) * 0.95; jquery(this).parents("form").find("input[name='price']").val(calc); }); this, form input:
<input class="irrelevant typeahead" type="text" placeholder="amount" name="amount"/> the javascript takes value, calculates price, , want fill this:
<input type="hidden" name="price" value=""/> i believe javascript correct. need price make work?
