I am using jQUERY Validation in a form. It happens that it validates me the length of the fields, when focusing the mouse in another field, or when writing. However, it does not validate the fields when I press the button. I am using AJAX to send my data to the controller. The documentation mentions that the following lines should be used, but these do not work, curiously if I remove the id = "btn_insert"
of the button, validate it
$("#myform").validate({
submitHandler: function(form) {
$(form).ajaxSubmit();
}
});
FORM
<div class="modal fade" id="insert_modal" name="insert_modal" role="dialog" aria-labelledby="myModalLabel">
<div class="modal-dialog modal-md" role="document">
<div class="modal-content">
<div class="modal-header bg-blue">
<h5 class="modal-title text-info" id="myModalLabel">New Type
<button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">×</span></button>
</div>
<div class="modal-body m-3">
<p>Add a new payment type</p>
<form id="insert_payment" name="insert_payment">
<div class="form-group">
<label class="control-label">Code</label>
<input type="text" class="form-control" id="code" name="code" required>
</div>
<div class="form-group">
<label class=" control-label">Description</label>
<input type="text" class="form-control" id="type" name="type" required>
</div>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-danger" id="btn_cancel" data-dismiss="modal">Cancelar</button>
<input class="btn btn-info ml-3" type="submit" value="Insert" id="btn_insert">
</div>
</form>
</div>
</div>
</div>
Javascript
jQuery(document).ready(function(){
$("#insert_payment").validate({
rules: {
code: { required: true, minlength: 3},
type: { required: true, minlength: 5}
},
submitHandler: function(form) {
$(form).ajaxSubmit();
}
});
$("#btn_insert").click(function(e){
e.preventDefault();
var _form = $("#insert_payment").serialize();
console.log("form:\n", _form);
$.ajax({
url: "<?=base_url();?>payment/insert/", type: 'post', data: _form,
success: function(response) {
console.log("response modal new :\n", response);
$("#insert_modal").modal('hide');
$("#modal_alert").modal('show');
$('#tblPayment').DataTable().ajax.reload();
$("#code").val("");
$("#type").val("");
}
});
});
});
You can try something like this.
jQuery(document).ready(function(){
$("#insert_payment").validate({
rules: {
code: { required: true, minlength: 3},
type: { required: true, minlength: 5}
},
submitHandler: function(form) {
sendData(form);
}
});
var sendData = function(form) {
var _form = form.serialize();
console.log("form:\n", _form);
$.ajax({
url: "<?=base_url();?>payment/insert/", type: 'post', data: _form,
success: function(response) {
console.log("response modal new :\n", response);
$("#insert_modal").modal('hide');
$("#modal_alert").modal('show');
$('#tblPayment').DataTable().ajax.reload();
$("#code").val("");
$("#type").val("");
}
});
}
});
I added the requirements in the HTML, like this:
<input type="text" class="form-control" name="code" minlength="3" required>
Here's working example code (including some HTML fixes, like adding a missing </h5>
:
function success(response) { // ... } function submitHandler() { var formData = $(this.currentForm).serialize(); console.log("formData:\\n", formData); $.post("payment/insert/", formData, success); return false; // don't submit form the non-AJAX way } $(document).ready(function() { $("#insert_payment").validate({ submitHandler: submitHandler }); });
