I'm want to run a self created function and then when true run a jQuery Mobile PopUp, but don't know how?
Here is what I think I should do:
$(document).ready(function() {
var finished = false;
$("#mytest").click(function() {
// RUN MY FUNCTION AND THE IF TRUE RUN POPUP
if(finished == true){
// ACTIVATE JQUERY MOBILE POPUP FUNCTION
}
});
});
I then should activate mytest function like this:
<a style="height: 75px;" href="" data-rel="popup" data-role="button" id="mytest">Test</a>
Nothing seems to happen though? I don't seem to get inside the mytest function? And when I do get in, how do I activate the popup function?
Hoping for help :-)
see working example: finished == true and finished == false: click the button and see what happens...
1) finished == true: the popup opens automatically
2) finished == false: I used return false to prevent opening the popup
script:
$(document).bind('pageinit', function() {
$("#mytest").click(function() {
var finished = false;
// RUN MY FUNCTION AND THEN IF TRUE RUN POPUP (WILL OPEN AUTOMATICALLY)
if(finished == false){
// PREVENT OPENING POPUP
return false;
}
});
});

Using the Bootstrap framework, how can I trigger an alert with a button click?
I thought this would be straightforward, but I couldn't find any clear examples from the Bootstrap documentation: https://getbootstrap.com/docs/5.0/components/alerts/.
If you know basic javascript, this probably isn't hard, but for newbies like me it's helpful to have a simple example.
Below is how I did it. I'm posting the full html with javascript, so it's easy to copy and paste, for example into https://www.w3schools.com/html/tryit.asp.

Here I have link when the link is clicked tweet.html file will be called. But when I clicked the back button I will be directed to the previous page without any error. But second time onwards when I click the back button I will be directed to the previous page and comes to the current page again.
$("#mybtn").unbind();`
unbind event will prevent this
I have a page called index.html, when I click the link in index html it will navigate to the another page which has Listview populated with data taken from Server. This Works without any error.
However, when I click the back button of current page, I will be directed to the previous page.
My question is, it refreshes current page and then go back to the previous page.
I need to prevent this.

I'm currently building a mobile site for iPad using jquery mobile and ASP.NET MVC 4. I have a dynamically created listview that is displaying search results. I want the user to be able to click on an item in the listview and have the text from that particular list item appear in a textbox that is also in the view.
I can get this to work in Safari on my desktop machine, but it will not work on an iPad.
For the sake of simplicity and to attempt to narrow down the problem, I hard-coded a simple little listview in my View. The results were the same. Works on desktop in Safari, but not on iPad.
Here is the very simplified VIEW code that works in Safari on desktop (Please note that _Header is a separate, partial View):
#section Header
{
<script type="text/javascript">
$('#testJs li').on('click', (function () {
var results = $.trim($(this).text());
$('#testText').val(results);
}));
</script>
#{ Html.RenderPartial("_Header"); }
}
#section Content
{
<input type="text" id="testText">
<ul id="testJs" data-role="listview" data-inset="true" data-theme="c">
<li id="task400" class="tasks">Test task 400</li>
<li id="task295" class="tasks">Test task 295</li>
</ul>
}
Please note that I have tried changing 'click' to 'tap' (see below) with no success. It still doesn't work on iPad.
<script type="text/javascript">
$('#testJs li').on('tap', (function () {
var results = $.trim($(this).text());
$('#testText').val(results);
}));
</script>
I've also tried using the following with the same results. Still doesn't work on the iPad.
<script type="text/javascript">
$('#testJs').delegate('li', 'tap', function () {
var results = $.trim($(this).text());
$('#testText').val(results);
});
</script>
I do wonder if this has something to do with our use of layout pages. We have slightly different layout pages, depending on if the site is being rendered on a mobile device or not.
Mobile Layout View:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title>#ViewBag.Title</title>
<meta name="viewport" content="width=device-width, initial-scale=1" />
#Scripts.Render("~/bundles/jquery", "~/bundles/jquerymobile")
#Scripts.Render("~/bundles/modernizr")
#Styles.Render("~/Content/mobileCss", "~/Content/css")
<script type="text/javascript">
$(document).ready(function () {
$.mobile.ajaxEnabled = false;
});
</script>
</head>
<body>
<div data-role="page" data-theme="b">
<div data-role="header" data-position="fixed" data-tap-toggle="false">
#if (IsSectionDefined("Header")) {
#RenderSection("Header", false) }
else { <h1>#ViewBag.Title</h1> }
</div>
<div data-role="content">
#RenderSection("Content")
</div>
</div>
</body>
</html>
Desktop Layout View:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8" />
<title>#ViewBag.Title</title>
<link href="~/favicon.ico" rel="shortcut icon" type="image/x-icon" />
#Scripts.Render("~/bundles/jquery", "~/bundles/jquerymobile")
#Scripts.Render("~/bundles/modernizr")
#Styles.Render("~/Content/mobilecss", "~/Content/css")
</head>
<body>
<div data-role="page" data-theme="b">
<div data-role="header" data-position="fixed" data-tap-toggle="false">
#if (IsSectionDefined("Header")) {
#RenderSection("Header") }
else { <h1>#ViewBag.Title</h1> }
</div>
<div data-role="content">
#RenderSection("Content")
</div>
</div>
</body>
</html>
I've been stuck on this for a few days, so any help would be appreciated. Everything I try works on my desktop, but not on an iPad - which is where I actually need it to function.
Thanks!
Did you try using bind on your testJs li? I'd bind a tapHandler like below:
<script>
$(function(){
$( "#testJs li" ).bind( "tap", tHandler );
function tHandler( event ){
var results = $.trim($(this).text());
$("#testText").val(results);
}
});
</script>
or with on like this should work:
$('#testJs').on('tap', 'li', function (event) {
var results = $.trim($(this).text());
$("#testText").val(results);
console.log('this should work')
}
Also used double quotes on top example but that shouldn't make a difference I don't think. If it doesn't then make sure you .js references are correct, and use firebug in firefox to debug for any straggling errors.
I am tryign to implement a random answer on a page loaded via an ajax call. I am using jquery mobile inclusive layout. Therefore I added a simple java script in the div data-roll container and initialized it via $(document).live or $(document).on or $(document).bind, like it should be according to many answers or suggestions here. Everything works fine, when I use a normal alert function. Like this
<script>
$(document).live('pageinit', "#answerPage", function (event) {
alert("Page Initialized");
});
</script>
Also my script works fine, when I add it to a normal html page.
So when I instead using an alert I use function getanswer() it doesn`t work. What do I do wrong here? Thanks for your help.
