Jquery Form Validation Before Ajax Submit, Easy Form Validation With Jquery

$(document).ready(function() $("#form").submit(function(e) e.preventDefault(); var $size = $(this); // kiểm tra if the input đầu vào is valid if(! $khung.valid()) return false; $.ajax( type:"POST", url:"add.php", data:$("#form").serialize(), success:function(response) $("#answers").html(response); ); ) );HTML bit:

So this is the code I am trying khổng lồ use. The idea is khổng lồ get all my inputs validated before I send my khung with Ajax. I"ve sầu tried numerous versions of this now but every time I over up with submitting even though the size is not entirely filled out. All my inputs are of the "required" class. Can anyone see what I am doing wrong?

Also, I depkết thúc on class-based requirements as my input đầu vào names are generated with php so I can never be sure what name or đầu vào types I get.

You could use the submitHandler option. Basically put the $.ajax gọi inside this handler, i.e. invert it with the validation thiết đặt xúc tích và ngắn gọn.

$("#form").validate( ... your validation rules come here, submitHandler: function(form) $.ajax( url: form.action, type: khung.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 lớn add the classRules explicitly since required is automatically detected by the jquery.validate plugin.so you can use this code :

on khung submit , you prevent the default behavior if the khung is Invalid stop the execution.else if valid skết thúc the ajax request.

You can try doing:

if($("#form").validate()) return true; else return false;

This specific example will just kiểm tra for inputs but you could tweak it however, Add something lượt thích this lớn 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 lớn 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 kết thúc of the script.

You need khổng lồ 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 sự kiện but at the document level. So your event handler is being triggered before jquery validates the whole khung. But fret not, there"s a simple solution khổng lồ all of this.

You should validate the form:

if ($(this).validate().form()) // do ajax stuffhttps://jqueryvalidation.org/Validator.form/#validator-form()
