So this is the code I am trying to use. The idea is to get all my inputs validated before I send my form with Ajax. I”ve tried numerous versions of this now but every time I end up with submitting even though the form is not entirely filled out. All my inputs are of the “required” class. Can anyone see what I am doing wrong?
Also, I depend on class-based requirements as my input names are generated with php so I can never be sure what name

You could use the submitHandler option. Basically put the $.ajax call inside this handler, i.e. invert it with the validation setup logic.
$(“#form”).validate({ … your validation rules come here, submitHandler: function(form) { $.ajax({ url: form.action, type: form.method, data: $(form).serialize(), success: function(response) { $(“#answers”).html(response); } }); }});The jQuery.validate plugin will invoke the submit handler if the validation has passed.

first you don”t need to add the classRules explicitly since required is automatically detected by the jquery.validate plugin.so you can use this code :
on form submit , you prevent the default behavior if the form is Invalid stop the execution.else if valid send the ajax request.

You can try doing:
if($(“#form”).validate()) { return true;} else { return false;}

This specific example will just check for inputs but you could tweak it however, Add something like this to your .ajax function:
beforeSend: function() { $empty = $(“form#yourForm”).find(“input”).filter(function() { return this.value === “”; }); if($empty.length) { alert(“You must fill out all fields in order to submit a change”); return false; }else{ return true; };},

I think submitHandler with jquery validation is good solution. Please get idea from this code. Inspired from
Darin Dimitrov
$(“.calculate”).validate({ submitHandler: function(form) { $.ajax({ url: “response.php”, type: “POST”, data: $(form).serialize(), success: function(response) { $(“#”+form.id+” .ht-response-data”).html(response); } }); } });

I think that i first validate form and if validation will pass, than i would make ajax post. Dont forget to add “return false” at the end of the script.

You need to trigger form validation before checking if it is valid. Field validation runs after you enter data in each field. Form validation is triggered by the submit event but at the document level. So your event handler is being triggered before jquery validates the whole form. But fret not, there”s a simple solution to all of this.
You should validate the form:
if ($(this).validate().form()) { // do ajax stuff}https://jqueryvalidation.org/Validator.form/#validator-form()

Form native JavaScript checkValidity function is more then enough to trigger the HTML5 validation
$(document).ready(function() { $(“#urlSubmit”).click(function() { if($(“#urlForm”)<0>.checkValidity()) { alert(“form submitting”); } });});
