I just learned how to create and append items. I wanted to practice using a button to submit the text to be appended. It works, however, the page seems to refresh right afterwards and removes the text from the list. What am I doing wrong?
HTML:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>To Do List</title>
<link rel="stylesheet" href="ToDo.css">
</head>
<body>
<h1>To Do:</h1>
<ul>
<li class="todo">Create another todo.</li>
</ul>
<form>
<input type="text" placeholder="Add another item!">
<button onclick="output()">Add</button>
</form>
<script src="ToDo.js"></script>
</body>
</html>
JS:
let ul = document.querySelector('ul');
newItem = document.querySelector('input');
function output() {
let item = newItem.value;
let newTodo = document.createElement('li');
newTodo.innerText = item;
newTodo.classList.add('todo');
ul.append(newTodo);
}
Your button is submitting the form which is causing the page to refresh. Buttons are made to be type submit by default.
It looks like you don't actually need the form so you could either remove it or set the type on the button:
<button type="button" onclick="output()">Add</button>

I am new to SAPUI5. I'm able to create controls in my SAPUI5 mobile application.But I'm not able to set them in a layout. I'm writing my view as HTML page and adding my controls to that. I have tried placing them in a division but I don't know what is the attribute to specify layout.Please guide about the layouts.
Thanks
<template data-controller-name="sample.controllers.index">
<div data-sap-ui-type="sap.m.Page" data-title="Title">

This is my sample code and when i run this on browser it shows me a error message that

There is no such a control like sap.m.Layout. For layout, you can choose any from the sap.ui.layout controls, for example, sap.ui.layout.Grid
I'm trying to figure out how to apply a custom javascript function to a dropdown menu element that is located in the iframe. Javascript changes the look and feel of the dropdown and works great for the parent page. It doesn't work for an element in the iframe. I searched this website for an answer but unfortunately some of the examples given here didn't work for my page. A couple of things to keep in mind:
Both pages are in the domain
I can't directly place the js on the page that is loaded in the iframe(code below is just an example, the real thing is not accessible to me)
I'm using the js libraries found here(i modified it a bit to fit my needs) http://www.marghoobsuleman.com/jquery-image-dropdown
Here's the page that will be loaded in iframe. I'm trying to style the select element:
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<title>Iframe</title>
</head>
<body>
<label for="specialty">Specialty: </label>
<select name="specialty" id="specialty" class="dropdown">
<option value="calendar">Calendar</option>
<option value="shopping_cart">Shopping Cart</option>
</select>
</body>
</html>
Here's the parent from which I try to invoke the js:
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<title>Parent Page</title>
<link rel="stylesheet" type="text/css" href="css/style.css" />
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script>
<script src="js/jquery.dd.js" type="text/javascript"></script>
<script type="text/javascript">
$(document).ready(function(e) {
try {
$("body select").msDropDown();
}
catch(e) {
alert(e.message);
}
});
$('#frame').load( function(){
try {
$(this.contentDocument).find('select').msDropDown();
}
catch(e) {
alert(e.message);
}
});
</script>
</head>
<body>
<label for="specialty">Specialty: </label>
<select name="specialty" id="specialty" class="dropdown">
<option value="calendar">Calendar</option>
<option value="shopping_cart">Shopping Cart</option>
</select>
<iframe src="add.html" id="frame" name="frame"></iframe>
</body>
</html>
Thanks in advance
As far as I can tell, this doesn't seem possible. It may be an issue with the plugin itself, in that even executing the function on the DOM of the iframe, the function instead executes on the DOM of the parent.

this is my photography tutorial page. I'm did manage to toggle on/off when someone clicks a question.
What I can't do : the top right button can expand all but it cannot contract all questions.
I should contract/expand all even if some of them were previously opened. At first my code was doing the opposite of previous state.
How can I do that?
Here is my code :
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
<link rel="stylesheet" type="text/css" href="styles.css"/>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script>
<script type="text/javascript">
$(document).ready(function(){
$("li").click(function(){
$(this).next().toggle("fast");
$(li).css("background-color","#999");
$(article).css("background-color","#FDFEE9");
});
$(document).ready(function(){
$("#expand").click(function(){
$("article").toggle(true);
$(this).text($(this).text() == 'Genişlet' ? 'Küçült' : 'Genişlet');
});
$("article").toggle();
});
});
</script>
</head>
<body>
<div id="page"><h1>Temel Fotoğrafçılık Bilgileri<button id="expand">Genişlet</button></h1>
<div class="faq">
<!-- The FAQs are inserted here -->
<ul>
<li>question 1?</li>
<article> <p>answer 1.</p></article>
<li>question 2?</li>
<article> <p>answer 2.</p></article>
<li>question 3?</li>
<article> <p>answer 3.</p></article>
</ul>
</div>
</body>
</html>
Here is the working JSfiddle version:
http://jsfiddle.net/reJu9/
Change the expand click callback to
$("#expand").click(function(){
var $this = $(this);
if($this.text() == 'Genişlet')
$('article').show();
else
$('article').hide();
$this.text($this.text() == 'Genişlet' ? 'Küçült' : 'Genişlet');
});

Maintain a variable, which tells you if the button should expand or collapse questions.

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

<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.

I would like to append some code to a page using jQuery/jQuery mobile,
but I am tripping up on some of the page() and pageshow and refresh methods.
Here is my code. you can cut, paste and run as is.
<!DOCTYPE html>
<html>
<head>
<title>Page Title</title>
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="stylesheet" href="http://code.jquery.com/mobile/1.0b2/jquery.mobile-1.0b2.min.css" />
<script type="text/javascript" src="http://code.jquery.com/jquery-1.6.2.min.js"></script>
<script type="text/javascript" src="http://code.jquery.com/mobile/1.0b2/jquery.mobile-1.0b2.min.js"></script>
<script>
//$(document).ready(function() // get error when I use this
$('div').live('pageshow', function () {
function fnCreateGroups(){
var section = "<p>and add a whole bunch of html code...</p>";
myClone = $(section);
alert((myClone).html()); // this works
myClone.appendTo("#placeholder").page(); // but not appending
}
fnCreateGroups();
});
</script>
</head>
<body>
<div data-role="page">
<div id="placeholder">
<div data-role="content">
<div id="placeholder">this is a small amount of html code.</div>
</div>
</div>
</div>
</body>
</html>
Beta2 release notes:
http://jquerymobile.com/blog/2011/08/03/jquery-mobile-beta-2-released/
instead of:
myClone.appendTo("#placeholder").page();
try
myClone.appendTo("#placeholder").trigger('create');
From your comment:
You are running the live() on all div's
$('div').live('pageshow', function ()
try using the page id instead
$('#change_this_page_only').live('pageshow', function ()
and this:
<div data-role="page">
to something like this:
<div data-role="page" id="change_this_page_only">
