I try to send a form use ajax. I can send the information successfully. And I can receive the information. However, I can't get parameters form the request. I don't know the reason.
I try IE, FIREFOX, Chrome, none of them can send the form.
This is my code:
<%# page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<meta http-equiv="Expires" content="0">
<meta http-equiv="kiben" content="no-cache">

<%String account =(String) session.getAttribute("fail"); %>
</script>
<script language="javascript" type="text/JavaScript" src="jquery-1.3.2.min.js">
</script>
<script language="javascript" type="text/JavaScript">
window.onload = function fillChecklist(){
var error ="${sessionScope.fail}";;
if(null != error&& error!=""){
alert(error);
}
}
function doFind() {
if(document.getElementById("username").value.length>0&&document.getElementById("password").value.length>0){
$.ajax({
cache : false,
type : "POST",
url : "login",
data : $("#ajaxFrm").serialize(),
async : false,
error : function(request) {
alert(“error");
},
success : function(data) {
//$("#ajaxDiv").html(data);
alert(data);
}
});
}
}
</script>
</head>
<body>
<form id="ajaxFrm" >
UserName<input type="text" id="username" ><br />
Password  <input type="password" id="password">
</form>
<input type="checkbox" name="remember" id="remember">Remeber Username</input><br />
<input value="Submit" type="button" onClick="doFind()"/>
<input value="Delete" type="button" onClick="DelCookie()"/>
<div id="ajaxDiv"></div>
</body>
</html>
Please change your input type="button" to input type="submit" first, and then submit with ajax.e.g
<html>
<head>
<script type="text/javascript" src="jquery-1.8.3.js"></script>
<script type="text/javascript">
$("form#ajaxFrm").submit(function() {
var mydata = $("form#ajaxFrm").serialize();
console.log(mydata); //check data before send to server
$.ajax({
type: "POST",
url: "myUrlToPostData.php",
data: mydata,
success: function(response, textStatus, xhr) {
alert("success");
},
error: function(xhr, textStatus, errorThrown) {
alert("error");
}
});
return false;
});
</script>
</head>
<body>
<form id="ajaxFrm" method="post">
UserName<input type="text" id="username" name="username"/><br />
Password <input type="password" id="password" name="password"/>
<input value="submit" type="submit" name="submit"/>
</form>
</body>

Any simple way to implement semantic-ui form validation with google recaptcha if the recaptcha field is checked or empty?
To expand on Arpit's answer:
Here's a non-Angular solution that worked for me
Custom validation rule above your fields validation:
$.fn.form.settings.rules.recaptchaValidate = function() {
return (recaptchaVerified);
};
Add this to your validation:
recaptcha: {
identifier: 'recaptcha',
rules: [
{
type: 'recaptchaValidate',
prompt: 'Please complete reCaptcha validation.'
}
]
}
and your HTML:
<div class="required field">
<div class="g-recaptcha" data-sitekey="{your key here}" data-callback="correctCaptcha"></div>
<input type="hidden" name="recaptcha" id="recaptch-validation">
</div>
[ ... then this just before closing body tag ... ]
<script type="text/javascript">
var recaptchaVerified = false;
var correctCaptcha = function(response) {
recaptchaVerified = true;
};
var expiredCaptcha = function() {
recaptchaVerified = false;
};
</script>
use below validation for Google reCaptcha validation.
Script:
$(document).ready(function () {
$('.ui.form').form({
recaptcha: {
identifier: 'g-recaptcha-response',
rules: [
{
type: 'empty',
prompt: 'Please complete reCaptcha validation.'
}
]
}
},
{
onSuccess: function (event, fields) {
console.log('Success:', fields);
return false;
//event.preventDefault();
},
onFailure: function (error) {
console.log('Failure',error);
return false;
}
});
});

Since I'm new to this so Any Help will be appreciated. Thanks
saveValues is a function that returns a function. Within the returned function body you seem to attempt to use object literal syntax.
function() {
a: "something",
b: "something else"
}
is not valid syntax. You probably mean to return some object.
So, here's some background: I am working on a MEAN stack app for my school where we can read and post our Galaga and Dig Dig highscores to a mongo database.
I am getting an error:
POST http://url.com/api/scores 500 (Internal Server Error)
TypeError: Cannot read property 'userName' of undefined at /app/server.js:37:22
server.js:37 is:
app.post("/api/scores", function(req, res){
Score.create({
name:res.body.userName,
game:res.body.game,
points:res.body.userPoints
});
});
The index.html that the res.body.* is coming from is:
<!DOCTYPE html>
<html ng-app="nameOfApp">

<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.3.10/angular.min.js"></script>
<script src="core.js"></script>
</head>
<body ng-controller="mainController">
<div class="container">
<div class="jumbotron text-center">
<div class="container">
<h1>HelpDesk Gaming Leaderboard</h1>
</div>
</div>
<div class="container">

<td><b>Score</b></td>
</tr>
<tr ng-repeat="score in scores">

</table>
</div>
<br/>
<h2>Score?</h2>
<form>
<input name="userName" type="String" class="form-control" id="userName" ng-model="formData.userName" placeholder="Your Name">
<input name="game" type="String" class="form-control" id="game" ng-model="formData.game" placeholder="The game?">
<input name="userPoint" type="Number" class="form-control" id="userPoint" ng-model="formData.userPoint" placeholder="Points?">

</form>
</div>

</script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.2/js/bootstrap.min.js">
</script>
</body>
</html>
and the core.js, which is the angular piece is:
var nameOfApp= angular.module('nameOfApp', []);
nameOfApp.controller("mainController", ["$scope", "$http", function($scope, $http) {
$scope.formData = {};
// when landing on the page, get all scores and show them
$http.get('/api/scores')
.success(function(data) {
$scope.scores = data;
console.log(data);
})
.error(function(data) {
console.log('Error: ' + data);
});
$scope.createScore = function() {
$http.post('/api/scores', $scope.formData)
.success(function(data) {
$scope.formData = {};
$scope.scores = data;
console.log(data);
})
.error(function(data) {
console.log('Error: ' + data);
});
};
}]);
Thanks for your input, and if there are any stylistic things that I have wrong, I would love to hear them. I am trying to get better at MEAN stack development.
It's not res.body.* you want to use in your Score.create method, you want to be using req.body.*. 'req' is what has all the data from your http request.
Should be:
app.post("/api/scores", function(req, res){
Score.create({
name:req.body.userName,
game:req.body.game,
points:req.body.userPoints
});
});
I have searched this forum for answers and have tried different suggestions that worked for others but did not work for me - including adding the site address to the whitelist in config.xml.
I am working on developing a web app using HTML5, CSS and JavaScript with Cordova 3.5.0-0.2.6 and jQuery Mobile 1.4.3 for the UI. I am using a multi-page JQM page model with the need to make ajax request to submit forms to a server.
Testing the code on localhost works fine but when I build on Android platform in Cordova, the request is not even sent at all as I get the alert message I wrote for when the request is not sent ("Could not connect!").
The code is supposed to use the JSON object returned from the server to display the next page. My codes are as shown below:

When I enter special character as content as pass it to Ajax call I am getting an error :( Ajax call works fine with out any special characters...
Is there any way to encode the data before passing it to ajax call???Please help me on this...
Thanks in advance.
(1.)Either you should put your data into a form and serialize it and then send to the server
(2.)Second way is you can use the js inbuilt function encodeURIComponent().
