I would like to create a popup form which will ask a user if he/she agrees with the terms and condition and has a post and cancel button. How could I create one? Could you give me an example. Thank you.
<html>
<head>
<script type="text/javascript">
<!--
function confirmation() {
var answer = confirm("Leave tizag.com?")
if (answer){
alert("Bye bye!")
window.location = "http://www.google.com/";
}
else{
alert("Thanks for sticking around!")
}
}
//-->
</script>
</head>
<body>
<form>
<input type="button" onclick="confirmation()" value="Leave Tizag.com">
</form>
</body>
</html>
Taken from TizTag...or you could use jQuery Dialog :)

I am working on a spring mvc project and I have a problem. What I want is that, when the user clicks submit, we should not leave the page, we should just stay. But the values submitted would be used as a parameter to a function in the same page. Here, let's just say I want to print it, and that is the part that is wrongly entered.
What should I do to accomplish this? Please help
You can use ajax here when your submit button is clicked call this function and then using this call your ajax passed the value from your input to your server and then at your server side perform operation which you needed to do and then the result back to ajax .
Your form :
<form name="testForm" action="move.jsp">
<label><h1>Enter the data <h1/></label><br/>
<input type="text" name="DATA"><br/>
<input type="button" onclick="submit_values()">
<!--^^added this-->
</form>
<div id="result"><!--here data will come back--></div>
Then on click of your button submit_values() function will get called . i.e :
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"> </script>
<script>
function submit_values() {
//get input value
var values = $("input[name='DATA']").val();
console.log(values);
$.ajax({
type: 'POST',
data: {
values: values//passing to server
},
url: "Your_server_url",
success: function(data) {
alert(data);//this will display whatever server will return
$("#result").html(data);//add response back to show
}
});
}
</script>
Then at your server-side do like below :
String data =request.getParameter("values");//get value
String send_back = something(data);//call your function
out.println("DATA BACK"+send_back );//this will go back to ajax
I want to only hide the P0 paragraph using childNodes[x] . I wonder how it works because it hides the whole div with in this code:
<html>
<body>
<div id="myDiv">
<p>P0</p>
<p>P1</p>
</div>
<button onclick="hideFn();">hide</button>
<script>
function hideFn()
{
document.childNodes[0].childNodes[1].childNodes[1].style.display = "none";
}
</script>
</body>
</html>
</html>
You easily could have found the reason yourself by simply doing the traversal step by step:
document
the document
.childNodes[0]
the documentElement, also known as the root node (<html>)
.childNodes[1]
the <body>
.childNodes[1]
the <div>
I have two forms on a page containing Google captcha code, but only one code works. Does anyone know if you can use the same code with the same key on two forms on the same page?,
Thks,
Yes, you can. But you have to explicitly render the widget as mentioned on the developer guide
you should use something like this on your front end(taken from the developer guide):
<html>
<head>
<title>reCAPTCHA demo: Explicit render for multiple widgets</title>
<script type="text/javascript">
var verifyCallback = function(response) {
alert(response);
};
var widgetId1;
var widgetId2;
var onloadCallback = function() {
// Renders the HTML element with id 'example1' as a reCAPTCHA widget.
// The id of the reCAPTCHA widget is assigned to 'widgetId1'.
widgetId1 = grecaptcha.render('example1', {
'sitekey' : 'your_site_key',
'theme' : 'light'
});
widgetId2 = grecaptcha.render(document.getElementById('example2'), {
'sitekey' : 'your_site_key'
});
grecaptcha.render('example3', {
'sitekey' : 'your_site_key',
'callback' : verifyCallback,
'theme' : 'dark'
});
};
</script>
</head>
<body>
<!-- The g-recaptcha-response string displays in an alert message upon submit. -->
<form action="javascript:alert(grecaptcha.getResponse(widgetId1));">
<div id="example1"></div>
<br>
<input type="submit" value="getResponse">
</form>
<br>
<!-- Resets reCAPTCHA widgetId2 upon submit. -->
<form action="javascript:grecaptcha.reset(widgetId2);">
<div id="example2"></div>
<br>
<input type="submit" value="reset">
</form>
<br>
<!-- POSTs back to the page's URL upon submit with a g-recaptcha-response POST parameter. -->
<form action="?" method="POST">
<div id="example3"></div>
<br>
<input type="submit" value="Submit">
</form>
<script src="https://www.google.com/recaptcha/api.js?onload=onloadCallback&render=explicit"
async defer>
</script>
</body>
</html>
I just wanted a HTML snipped which I can insert multiple times, each time displaying another captcha. Also, I did not want to take care for specific IDs assigned to the containers, which would be very annoying when multiple formulars still appearing on one page will be designed and rendered independently. Here is my solution.
<div class="g-recaptcha"></div>
<script type="text/javascript"><![CDATA[
function renderCaptchas() {
var captchaNodes = document.getElementsByClassName('g-recaptcha');
for (var i = 0; i < captchaNodes.length; i++) {
var captchaNode = captchaNodes[i];
if (!captchaNode.captchaRendered) {
captchaNode.captchaRendered = true;
grecaptcha.render(captchaNode, {"sitekey": "YOUR_SITE_KEY"});
}
}
}
]]></script>
<script src="https://www.google.com/recaptcha/api.js?onload=renderCaptchas&render=explicit" async="async" defer="defer"></script>
I'm trying to create a Dojo dialog in Zend Framework but I've run into some problems. My view code looks something like this:
<script type="text/javascript" src="<?= $this->baseUrl('/js/dojo-release-1.7.2/dojo/dojo.js')?>"
data-dojo-config="async: true" dojoConfig = "parseOnLoad: true">
</script>
<script>
require(["dijit/registry", "dojo/ready", "dojo/dom", "dijit/Dialog", "dijit/form/Form"],
function(registry, ready, dom, Dialog){
ready(function() {
createDialog = function(titleText, contentText) {
var node = dojo.byId("foobar");
var myDialog = new Dialog({ title:"From Source Node" }, node);
myDialog.show();
};
});
});
</script>
<body class="claro">
<div data-dojo-type="dijit/Dialog" id="foobar" title="Foo!" style="display: none">
<p>I am some content</p>
</div>
</body>
The button code that loads the dialog looks as follows:
<button name="btnDialog" id="dialogbtn" type="button" onclick='createDialog();'>Open</button>
The first time the button is clicked the dialog opens as expected, but once the dialog is closed and the button is clicked again, the dialog doesn't open and I get the following error in the console.
Tried to register widget with id==foobar but that id is already registered.
What am I doing wrong?
Thanks
Figured it out. I think the form wasn't parsing correctly because the dojo-config was incorrect. Changed the javascript code as follows:
<script type="text/javascript" src="<?= $this->baseUrl('/js/dojo-release-1.7.2/dojo/dojo.js')?>"
data-dojo-config="async: true, parseOnLoad:true">
</script>
<script>
require(["dijit/registry", "dijit/Dialog"], function (registry)
{
createDialog = function createDialog()
{
registry.byId("foobar").show();
}
});
</script>
and the div as follows:
<body class="claro">
<div class="dijitHidden">
<div data-dojo-type="dijit.Dialog" data-dojo-props="title:'Foo!'" id="foobar">
<p>I am some content</p>
</div>
</div>
</body>
and now the dialog dijit is saved to the registry and it's working as expected
I am new to jquery mobile, and am having problems getting content I have inserted dymically using pageinit to display on the first time of the form response page. It displays on subsequent refreshes of the page. I also don't want the content to cache.
I need to use querystring values like ?blah=1&blah=2 as I use these in my call to an external json file.
How should I be doing this? If I use rel="external", and setting ajax to false, I have problems with issues on android. So using pageinit in the header, how do I make the dynamically loaded content (in the example, the time in seconds) in the 2nd page display first time round?
I have simplified the problem into test pages below.
Expected behaviour. When you click on the submit button of the form you go through to the 2nd page which should display the no of seconds taken from datetime
Actual behaviour. The seconds/time does not display on the 2nd page until the page is refreshed.
Elsewhere, I have come across the suggestion to put the pageinit code into the div itself, however this has caused the content to cache on android (ie the no of seconds remains the same), so I don't want to do this.
Any ideas on how I should approach this would be much appreciated
Sample code

Page 2 form response page

<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="stylesheet" href="http://code.jquery.com/mobile/1.0.1/jquery.mobile-1.0.1.min.css" />

<body>
<div data-role="page" id="page2" data-add-back-btn="true">
<div id="job" data-role="content">
</div>
</div>
</body>
</html>
===
custom javascript file called /scripts/myinit.js (included in both pages above)
$('#page1').live('pageinit', function(event) {
var seconds = new Date().getTime();
$('input[name=seconds]').val(seconds);
});
$('#page2').live('pageinit', function(event) {
var querystring = location.search.replace( '?', '' ).split( '&' );
var queryObj = {};
for ( var i=0; i<querystring.length; i++ ) {
var name = querystring[i].split('=')[0];
var value = querystring[i].split('=')[1];
queryObj[name] = value;
}
var seconds = queryObj["seconds"];
$('#job').append("seconds=" + seconds);
});
try changing pageinit by pageshow. i had the same problem and it worked for me
Link to the external file like this:
HTML --
I'm a Link
JS --
$(document).delegate('#external-link', 'click', function () {
$.mobile.changePage('/path/to/file.html', { reloadPage : true });
return false;
});
Setting the reloadPage option for the changePage() function will allow the external page to be refreshed rather than loading the cached version. Since the external page will be refreshed, the pageinit code for it will run when it's initialized and your code should function properly.
