jQuery验证阻止表单提交

Question

I am not sure why this form is submitting. I have copied the code from other examples and replaced it with my content, but it keeps submitting the form even though i have put in return false

Also when ports ICMP is selected it, it does not validate the other rules and submits the form.

 $("form[name='frmAddCMRow']").validate({ /* showErrors: function(errorMap, errorList) { $.each(this.successList, function(index, value) { $(value).popover('hide'); }); $.each(errorList, function(index, value) { var _popover = $(value.element).popover({ trigger: 'manual', placement: 'top', content: value.message, template: '<div class="popover"><div class="arrow"></div><div class="popover-inner"><div class="popover-content"></div></div></div>' }); _popover.data('bs.popover').options.content = value.message; $(value.element).popover('show'); }); }, */ submitHandler: function() { var formdata = $('form').serialize(); console.log(formdata); return false; }, rules: { src: { required: true, messages: { required: "Please enter Source IP", } }, dst: { required: true, messages: { required: "Please enter Destination IP", } }, ports: { required: function() { return $("form[name='frmAddCMRow'] select[name='protocol']").val() != "ICMP"; }, messages: { required: "Please enter Ports", } }, }, });

Answer 1

The name of the form in your selector, $("form[name='frmAddCMRow']") , does not match the name of your actual form, frm_rename_commsmatrix . Therefore, the jQuery Validate plugin is not being initialized on your form.

Try $("form[name='frm_rename_commsmatrix']") instead.
