<script> // Example starter JavaScript for disabling form submissions if there are invalid fields (function() { 'use strict'; window.addEventListener('load', function() { // Fetch all the forms we want to apply custom Bootstrap validation styles to var forms = document.getElementsByClassName('needs-validation'); // Loop over them and prevent submission var validation = Array.prototype.filter.call(forms, function(form) { form.addEventListener('submit', function(event) { if (form.checkValidity() === false) { event.preventDefault(); event.stopPropagation(); } form.classList.add('was-validated'); }, false); }); }, false); })(); </script>
分析,将关键的拿出来,下面是修改后:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15
<script> var valiRes = "";
//$(.ifForm)是要验证的目标表单 Array.prototype.filter.call($('.ifForm'), function (target) { valiRes = target.checkValidity(); $('.ifForm').addClass('was-validated'); });
