Is it possible to add show password functionality in login form of sylius? This script is not working

function myFunction() {
var showpass = document.getElementsByClassName('lpass');
if (showpass.type === "password") {
showpass.type = "text";
} else {
showpass.type = "password";
}
}
This script is not working. In console.log('') it is skipping to else condition directly.

Your var showpass = document.getElementsByClassName('lpass'); returns an array so use the 0 index to get the first match.
var showpass = document.getElementsByClassName('lpass')[0];
You can see more about the function here, https://developer.mozilla.org/en-US/docs/Web/API/Document/getElementsByClassName

Getting multiple submit using for loop in javascript

I am using a for loop to check whether the user has attached the required documents or not. Based on the success I am submitting it to the server. I would like to make it simple. Even the validation passes it should submit the data only once instead of many times.
I have put the submit inside the loop for each success it will submit the data.
can anyone suggest me how I can make it simpler?
function validateFile () {
if (vm.imageURIs.length > 0) {
for (var i = 0; i < vm.imageURIs.length; i++) {
var data = vm.imageURIs[i];
if (data.img && data.img.length > Config.ENV.FILE_SIZE) {
var fileName = data.name || vm.i18n.documentNumber + (i + 1);
Toast.message($translate.instant('DOCUMENTMAXSIZE', { name: fileName }));
} else if (data.document_required === true && data.img.length === 0) {
Toast.message($translate.instant('DOCUMENTREQUIRED', {name: data.name}));
} else {
applyScheme();
}
}
} else {
applyScheme();
}
}

Try putting
break;
after
applyScheme();

How do i display only the specific console when my condition inside loop is met

THIS IS MY CONTROLLER FUNCTION:
$scope.Save = function () {
for(var i = 0; i < $scope.listOfnames.length; i++){
if($scope.listOfnames[i].surname == $scope.name.surname){
console.log("This surname is already exist!");
}else{
console.log("save this surname.");
}
}
}
THIS MY OUTPUT IN CONSOLE :
save this surname.
This surname is already exist!
save this surname.
FOR EXAMPLE, I HAVE ALREADY A "STUART" SURNAME IN MY $scope.listOfnames,
AND WHEN I INPUT "STUART" SURNAME ALSO IN MY SURNAME INPUT FIELD,
IT MUST DISPLAY "This surname is already exist!" ONLY IN MY CONSOLE.
I KNOW THAT I HAVE A PROBLEM ON MY FOR LOOP, WHAT SHOULD I DO?

You are getting that on console because "STUART" is the second value on your array. You can do something like:
$scope.Save = function () {
var found = false;
//Loop thru the array and check each. If found change the value of var found
for(var i = 0; i < $scope.listOfnames.length; i++){
if( $scope.listOfnames[i].surname == $scope.name.surname ){
found = true;
}
}
if ( found ) {
console.log("This surname is already exist!");
} else {
console.log("save this surname.");
}
}

Simpy cannot iterate over javascript object?

I have scoured the other question/answer for this and implemented everything and I still cannot access the values of the object. Here's the code I am using:
function apply_voucher(voucher) {
var dates = $.parseJSON($("[name='dates']").val());
var voucher_yes_no = new Array();
var voucher_reduction = new Array();
if(voucher.length > 0)
{
$.each(dates, function(room_id, these_dates) {
$.post('/multiroom/check_voucher/'+voucher+'/'+room_id, function(result) {
if(result.result == 'ok') {
voucher_yes_no.push('yes');
voucher_reduction.push(result.voucher_reduction);
} else {
voucher_yes_no.push('no');
}
}, 'json');
});
// check if there are any yes's in the array
if('yes' in voucher_yes_no) {
console.log("no yes's");
} else {
console.log(voucher_reduction);
console.log(typeof voucher_reduction);
for (var prop in voucher_reduction) {
console.log(prop);
console.log(voucher_reduction[prop]);
if (voucher_reduction.hasOwnProperty(prop)) {
console.log("prop: " + prop + " value: " + voucher_reduction[prop]);
}
}
}
}
}
Apologies for the constant console logging - I'm just trying to track everything to make sure it's all doing what it should. The console output I get from this is below:
...which shows the object containing one value, "1.01" and my console.log of the typeof it to make sure it is actually an object (as I thought I was going mad at one point). After this there is nothing from inside the for-in loop. I have tried jquery's $.each() also to no avail. I can't understand why nothing I'm trying is working!

It does not work because the Ajax call is asynchronous!
You are reading the values BEFORE it is populated!
Move the code in and watch it magically start working since it will run after you actually populate the Array!
function apply_voucher(voucher) {
var room_id = "169";
var dates = $.parseJSON($("[name='dates']").val());
var voucher_reduction = new Array();
$.post('/multiroom/check_voucher/'+voucher+'/'+room_id, function(result) {
if(result.result == 'ok') {
voucher_reduction.push(result.voucher_reduction);
}
console.log(voucher_reduction);
console.log(typeof voucher_reduction);
for (var prop in voucher_reduction) {
console.log(prop);
console.log(voucher_reduction[prop]);
if (voucher_reduction.hasOwnProperty(prop)) {
console.log("prop: " + prop + " value: " + voucher_reduction[prop]);
}
}
}, 'json');
}
From what it looks like, you plan on making that Ajax call in a loop. For this you need to wait for all of the requests to be done. You need to use when() and then(). It is answered in another question: https://stackoverflow.com/a/9865124/14104

Just to say for future viewers that changing the way I did this to use proper deferred objects and promises, which blew my head up for a while, but I got there! Thanks for all the help, particularly #epascarello for pointing me in the right direction :) As soon as I started doing it this way the arrays began behaving like arrays again as well, hooray!
Here's the final code:
function apply_voucher(voucher) {
var booking_id = $("[name='booking_id']").val();
var dates = $.parseJSON($("[name='dates']").val());
if(voucher.length > 0) {
var data = []; // the ids coming back from serviceA
var deferredA = blah(data, voucher, dates); // has to add the ids to data
deferredA.done(function() { // if blah successful...
var voucher_yes_no = data[0];
var voucher_reduction = data[1];
if(voucher_yes_no.indexOf("yes") !== -1)
{
console.log("at least one yes!");
// change value of voucher_reduction field
var reduction_total = 0;
for(var i = 0; i < voucher_reduction.length; i++) {
reduction_total += voucher_reduction[i];
}
console.log(reduction_total);
}
else
{
console.log("there are no yes's");
}
});
}
}
function blah(data, voucher, dates) {
var dfd = $.Deferred();
var voucher_yes_no = new Array();
var voucher_reduction = new Array();
var cycles = 0;
var dates_length = 0;
for(var prop in dates) {
++dates_length;
}
$.each(dates, function(room_id, these_dates) {
$.post('/multiroom/check_voucher/'+voucher+'/'+room_id, function(result) {
if(result.result == 'ok') {
voucher_reduction.push(result.voucher_reduction);
voucher_yes_no.push('yes');
} else {
voucher_yes_no.push('no');
}
++cycles;
if(cycles == dates_length) {
data.push(voucher_yes_no);
data.push(voucher_reduction);
dfd.resolve();
}
}, 'json');
});
return dfd.promise();
}

Can you show how voucher_reduction is defined?
I am wondering where the second line of the debug output comes from, the one starting with '0'.

in this line:
console.log(vouncher_reduction[prop]);
^
The name of the variable is wrong (then) and probably that is breaking your code.

I think there are no problem with your loop.
But perhaps with your object.
Are you sure what properties has enumerable ?
Try to execute this to check :
Object.getOwnPropertyDescriptor(voucher_reduction,'0');
If it return undefined, the property was not exist.

Display All ().html in Javascript

Sorry for the lack of description in title, it's difficult to explain.
So I have a simple signup page and I made a bunch of functions in my code that check things such as the username length, make sure the passwords match, etc..
The problem is, if there is more than one error in the users input, it only displays one error at the bottom.
HEre is the JSfiddle: http://jsfiddle.net/LCBradley3k/xqcJS/19/
Javascript:
$('#join').on('click', function () {
var correct = true;
$('input[type="text"], input[type="password"]').each(function (indx) {
var $currentField = $(this);
if ($currentField.val() === '') {
$currentField.addClass('empty');
correct = false;
$currentField.one('keydown', function () {
$currentField.removeClass('empty');
});
} else {
$currentField.removeClass('empty');
}
});
function userLength() {
var x = $('input[name="user"]').val();
if (x.length < 6) {
$('#answer').html('Less than six characters.');
$('input[name="user"]').addClass('empty');
return false;
} else {
return true;
}
}
function passwordCheck() {
var x = $('input[name="password"]').val();
var y = $('input[name="passwordcheck"]').val();
if (x === y) {
return true;
} else {
$('#answer').html('Two different passwords');
$('input[name="password"], input[name="passwordcheck"]').addClass('empty');
return false;
}
}
function validateForm() {
var x = $('input[name="email"]').val();
if (x.indexOf('#') !== -1 && x.lastIndexOf(".") !== -1) {
return true;
} else {
$('#answer').html('Not a valid email');
$('input[name="email"]').addClass('empty');
return false;
}
}
if (correct) {
if (userLength()) {
if (passwordCheck()) {
if (validateForm()) {
$('#answer').html('Thank You!');
setTimeout(function () {
$('.inputs').hide("slide", {
direction: "up"
}, 1000);
}, 2000);
}
}
}
} else {
$('#answer').html('Please fill highlighted fields.');
}
});
You can see that all of them edit the #('#answer') div with .html(). But only one is displayed when there is more than one error. Once that error is fixed and the button is pressed, it will then display the next error. I want them all to be displayed in a list.

I created a fiddle that may be of some help. The idea is to create an array with the errors in it like so:
var errors = [];
errors.push("Error 1");
errors.push("Error 2");
As you step through the validation, every time an error is encountered you simply push the error string onto the array. When you get to the end of the validation you need to compile these errors into html like that can be appended to your $('#answer') element. In this case the items are compiled into an unordered list. You can change this to fit your needs.
var content = "<ul>";
for(var a = 0, len = errors.length; a < len; a++) {
content += "<li>" + errors[a] + "</li>";
}
content += "</ul>";
$('#answer').html(content);
The html is built dynamically and stored in the variable content. content is then appended to your html element that displays the errors (in your case answer).

You have 2 issues with doing what you want.
First, you are only continuing your checks if the first one passes, due to your nested if statements.
Second, you are replacing the #answer html with the message, which means even if you do each check, you will only see the results of the last one.
A simple fix would be to un-nest your if statements, and keep a variable that tracks the overall pass state. Secondly, instead of using .html(), use .append(), but make sure to clear out #answer before starting your checks.
correct &= checkFilled();
correct &= userLength();
correct &= passwordCheck();
correct &= validateForm();
if (correct) {
// ...
}
Fiddle: http://jsfiddle.net/jtbowden/9cFKW/
Note: I made your form filled check it's own function to work better with this method.
You can do some more fancy things, like pushing error messages on an array, and then checking the array for errors at the end and appending all of the messages, but this should get you started.
