Basic form of the code is given below that i want rectified. while running the code once it reaches .show() function the page is getting refreshed. I don't want that. Can you help me with this dilemma!!!!
Please see the code below :
Code:
$(document).ready(function() {
$("#mandate").hide();
$("#submit").click(function() {
var password = $("#password").val();
if(password=='') {
$("#mandate").show();
}
else {
alert("Form Submitted Successfully..!!");
}
}
}
HTML:
<p id="mandate"><font color="red">Password is mandatory*</font></p>
Add return false; to your code.
$(document).ready(function() {
$("#mandate").hide();
$("#submit").click(function() {
var password = $("#password").val();
if(password=='') {
$("#mandate").show();
return false;
}
else
{
alert("Form Submitted Successfully..!!");
}
});
The return false will return false to the event. That tells the browser to stop following events, like follow a link. It is similar to event.preventDefault()

My intention is to check some conditions before submit is done or stop it and show an alert if the results of that condition are false. I need to ask a function localized in another PHP document using POST.
The next case I'm going to show, the alert is showed correctly when "result != 1", but when I test the opposite case "result == 1", the submit doesnt work:
$('body').on("submit","#idForm",function(event) {
event.preventDefault();
$.post( 'php_file_rute.php', {action:'functionName'})
.done(function(result) {
if (result == 1) {
if(functionNameInSameJSPage()){
return true;
}else{
return false;
}
} else {
alert('error');
return false;
}
});
});
I tried in another way, putting event.preventDefault behind every "Return false" but when "result != 1" it shows the alert but do the submit anyways. It happens in every condition (submit doesnt stop).
$('body').on("submit","#formProyecto",function(event) {
$.post( 'php_file_rute.php', {action:'functionName'})
.done(function(result) {
if (result == 1) {
if(functionNameInSameJSPage()){
return true;
}else{
return false;
event.preventDefault();
}
} else {
alert("error");
event.preventDefault();
return false;
}
});
});
As you can see, my goal is to stop the submit if "result != 1" and show an alert or do the submit if all conditions are ok.
Any idea?
Thanks.
The issue you have is that you cannot return anything from an asynchronous function - which your AJAX request is.
To solve this you need to use preventDefault() to stop the form submit event through jQuery, then raise another native submit event if the AJAX request returns a valid result. This second submit event will not be handled by jQuery and will submit the form as you require. Try this:
$(document).on("submit", "#idForm", function(e) {
e.preventDefault();
var form = this;
$.post('php_file_rute.php', {
action: 'functionName'
}).done(function(result) {
if (result === 1) {
if (functionNameInSameJSPage()) {
form.submit();
}
} else {
alert('error');
}
});
});
This is assuming that functionNameInSameJSPage() is not an async function. If it is then you'll need to use the callback pattern there too.
This is a bit of a tricky one but you can kind of get it to work by doing:
$('body').on("submit","#idForm",function(event) {
event.preventDefault();
$.post( 'php_file_rute.php', {action:'functionName'})
.done(function(result) {
if (result == 1) {
if(functionNameInSameJSPage()){
$('#idForm').trigger("submit.force"); //Trigger submit again but under a different name
}
} else {
alert('error');
}
});
});
$('body').on("submit.force","#idForm", function () { return true; }); //Passthrough
The idea is to retrigger the event but ensure you don't call the same handler.
There's a proof of concept at https://jsfiddle.net/2kbmcpa4/ (there's no actual ajax happening but the promise simulates that, note this example won't work in IE)
Steps to solve the issue :
On actual form submit just block the event and make the rest call.
Based on response again dynamically resubmit by setting the allowSubmit flag.
Because flag is set on second submit, it doesn't prevent the form from submission. Reset the allowSubmit flag.
(function() {
var allowSubmit = false;
$('body').on("submit", "#idForm", function(event) {
var that = this;
if (!allowSubmit) {
event.preventDefault();
$.post('php_file_rute.php', {
action: 'functionName'
}).done(function(result) {
if (result == 1) {
if (functionNameInSameJSPage()) {
allowSubmit = true; // set the flag so next submit will not go though this flow
that.submit(); // dynamically trigger submit
}
} else {
alert('error');
}
});
} else {
allowSubmit = false; // reset the flag
}
});
})();
I've got a form with more than 1 inputfields. The format that should be allowed is hh:mm / h:mm. So I already have a function, that checks my input if the format is true inbstandly on input.
So what I want is, if i click on my submit button i'd like to check all the boxes again if the format is right. If true then submit(); else then alert() or something. But that isnt the problmem.
I have no idea how i can realize this. Thank you in advance :))
function validateAbs(inputField) {
var isValid = /^([0-1]?[0-9]|2[0-3]):([0-5][0-9])(:[0-5][0-9])?$/.test(inputField.value);
if (isValid) {
inputField.style.backgroundColor = '#bfa';
} else {
inputField.style.backgroundColor = '#fba';
}
return isValid;
}
$(function(){
$('#ist').on('input', function() {
//This is one of ne hh:mm Textboxes
validateAbs(this);
});
});
$(function(){
$('#abssubmit').on('input', function() {
//This is my Submit-Button
});
});
It's surprisingly easy:
$('#abssubmit').on('input', function() {
$("selector-for-the-inputs-you-want-to-check").each(function() {
validateAbs(this);
});
});
If you want to know whether any of them is invalid, you can use filter:
$('#abssubmit').on('input', function() {
var invalidFields = $("selector-for-the-inputs-you-want-to-check").filter(function() {
return !validateAbs(this);
});
if (invalidFields.length) {
// At least one field was invalid
}
});
You will need to change to a submit handler not an 'input' handler:
$('#abssubmit').on('submit', function(ev) {
var isValid;
ev.preventDefault(); // to stop the form from submitting
$('#ist').each(function() {
if (!validateAbs(this)) isValid = false;
});
if (isValid) {
this.submit(); // all the validations succeeded
}
});
I am pretty new to javascript.
Working on a wordpress I typed the following function in the custom js for my theme:
document.getElementsByName("empty_cart")[0].onclick = function(e) {
var choice = confirm("Are You Sure ?");
if (!choice) {
//Cancel submit
e.preventDefault();
}
};
This script allows for an "Are you sure you want to empty the cart?" confirmation, and works fine.
but when I added the following script that I copy and pasted from my email campaign provider ( robly ) the "are you sure" confirmation stopped working.
$(document).ready(function () {
$("#robly_embedded_subscribe").click(function (e) {
e.preventDefault();
var email = $("#DATA0").val();
if (!is_valid_email_address(email)) {
alert("Please enter a valid email address.");
return false;
}
var f = $("#robly_embedded_subscribe_form");
f.submit();
return false;
});
});
function is_valid_email_address(emailAddress) {
var pattern = new RegExp(/^((([a-z]|d|[!#$%&'*+-/=?^_`{|}~]|[u00A0-uD7FFuF900-uFDCFuFDF0-uFFEF])+(.([a-z]|d|[!#$%&'*+-/=?^_`{|}~]|[u00A0-uD7FFuF900-uFDCFuFDF0-uFFEF])+)*)|((x22)((((x20|x09)*(x0dx0a))?(x20|x09)+)?(([x01-x08x0bx0cx0e-x1fx7f]|x21|[x23-x5b]|[x5d-x7e]|[u00A0-uD7FFuF900-uFDCFuFDF0-uFFEF])|(([x01-x09x0bx0cx0d-x7f]|[u00A0-uD7FFuF900-uFDCFuFDF0-uFFEF]))))*(((x20|x09)*(x0dx0a))?(x20|x09)+)?(x22)))#((([a-z]|d|[u00A0-uD7FFuF900-uFDCFuFDF0-uFFEF])|(([a-z]|d|[u00A0-uD7FFuF900-uFDCFuFDF0-uFFEF])([a-z]|d|-|.|_|~|[u00A0-uD7FFuF900-uFDCFuFDF0-uFFEF])*([a-z]|d|[u00A0-uD7FFuF900-uFDCFuFDF0-uFFEF]))).)+(([a-z]|[u00A0-uD7FFuF900-uFDCFuFDF0-uFFEF])|(([a-z]|[u00A0-uD7FFuF900-uFDCFuFDF0-uFFEF])([a-z]|d|-|.|_|~|[u00A0-uD7FFuF900-uFDCFuFDF0-uFFEF])*([a-z]|[u00A0-uD7FFuF900-uFDCFuFDF0-uFFEF]))).?$/i);
return pattern.test(emailAddress);
}
I have attempted to remove the function is_valid snippet and move that to my functions.php file in my child theme... but that didn't work.
If anyone could help me out I would really appreciate it.
If you need any further information from me, please ask.
Often times with WordPress you need to change all instances of $ to jQuery
For example:
$(document).ready(function () { ... });
would become:
jQuery(document).ready(function () { ... });
This question has been done to death on SO and I'm really, really sorry! I've already taken the bones of the below idea from a couple of SO questions on the same theme.
All said though, I still can't get it to work as expected.
It works OK if NONE are filled in.
It works OK if the END input is filled in and not the others.
It works OK if the MIDDLE input is filled in.
If you fill in ONLY the FIRST input though, it alerts, but submits anyway?
JSFIDDLE
$(document).ready(function (e) {
// completed count submit handler
$("#submit_counts_button").on('click', function () {
window.incomplete = false;
$('input[type=number]').each(function () {
if ($(this).val().length == 0) {
window.incomplete = true;
alert('Some fields are empty');
return false;
} else {
if (window.incomplete === false) {
$("#submit_counts_button").prop('disabled', true);
$("#submit_counts_button").html('Please Wait ...');
//$("#update_form").submit();
}
}
});
});
});
I'm sure it's something totally embarrassingly obvious but after a 16 hour day, I just can't see it. Any help appreciated ...
You need to pull the 'incompletion' check outside of the .each
$(document).ready(function (e) {
// completed count submit handler
$("#submit_counts_button").on('click', function () {
window.incomplete = false;
$('input[type=number]').each(function () {
if ($(this).val().length == 0) {
window.incomplete = true;
alert('Some fields are empty');
return false;
}
});
if (window.incomplete === false) {
$("#submit_counts_button").prop('disabled', true);
$("#submit_counts_button").html('Please Wait ...');
//$("#update_form").submit();
}
});
});

I am using jQuery to validate some fields in a form, and seem to be having an issue with one field in particular (#inputTel).
If an incorrect format is entered, an error message pops up underneath, which is fine, but the problem is once the correct format is entered the message does not disappear.
Here's a jsFiddle with the complete demo.
This is the section in question:
//Tel Validate
function is_valid_tel() {
$this = $("#inputTel");
var pattern = new RegExp("^\d{11}$");
if (pattern.test($this.val())) { // valid
if ($this.closest(".control-group").hasClass("error")) $this.closest(".control-group").removeClass("error");
$this.siblings(".help-inline").css("display", "none");
return true;
} else { // error
if (!$this.closest(".control-group").hasClass("error")) $this.closest(".control-group").addClass("error");
$this.siblings(".help-inline").css("display", "block");
return false;
}
}
Every other field works as expected except this one. My jQuery skills are limited so I'm unsure of how to solve this.
Problem in your code:
Replace var pattern = new RegExp("^\d{11}$"); with var pattern = new RegExp(/^\d{11}$/);
Updated code
//Tel Validate
function is_valid_tel() {
$this = $("#inputTel");
var pattern = new RegExp(/^\d{11}$/);// Update this line
if (pattern.test($this.val())) { // valid
if ($this.closest(".control-group").hasClass("error")) $this.closest(".control-group").removeClass("error");
$this.siblings(".help-inline").css("display", "none");
return true;
} else { // error
if (!$this.closest(".control-group").hasClass("error")) $this.closest(".control-group").addClass("error");
$this.siblings(".help-inline").css("display", "block");
return false;
}
}

You could also use something like below, less cubersome:
$(function() {
function validateTheForm() {
var ok = true;
$(".input-medium").each(function() {
if($(this).val() == "") //use regex actually here
{
$(this).next().css("display","inline");
ok = false;
}
else {
$(this).next().css("display","none");
}
});
return ok;
}
$(".btn").click(function() {
$("form").submit(validateTheForm());
$("form").submit();
});
});
