javascript swap text block onclick anchor link - javascript

This should be easy but it's not working properly... I am quite rusty on javascript and can't figure out what it is I am missing.
I have a navbar that I'd like to disappear when person clicks on small arrow, leaving just a 2nd arrow. When user clicks on 2nd arrow, nav bar reappears. All of the navbar is in one tag. The nav menu itself is quite long, one reason, I want to give user ability to toggle it on and off.
Javascript function in head is as follows:
<script type="text/javascript">
function collapseMenu()
{document.getElementById("navbar").innerHTML ='<td id=navbar2><img src="arrow.gif"></td>';
}</script>
Text on page is:
<div id='navbar'>
<td>
<img src="arrow.gif">
</td>
</div>
Placing id in the div tag, it shows the arrow when you click on the link but doesn't remove the old html between the div tags. Same thing using span instead of div and no difference between single and double quotes. When I move the id="navbar" to the tag, the nav bar does disappear but it leaves the background color unchanged for the size of the old td tag. I would like it to go blank except for tiny arrow. So question 1 is why are div and span not working, or alternatively, td leaving background color in old space.
2nd question is how to specify innerHTM in text through a variable. It would be nice not to have to put this all in function in header.
Thanks for any ideas!

Don't know what a jsfiddle is but following code reproduces problem if put in .htm file. Thx.
<html>
<head>
<script type="text/javascript">
function hideBar()
{document.getElementById("navbar").innerHTML ='<td>show navbar</td>';
}</script>
<script type="text/javascript">
function hideBar2()
{document.getElementById("navbar2").innerHTML ='<td>show navbar</td>';
}</script>
</head>
<body>
<table width=500>
id in td tag
<tr>
<td rowspan=3 bgcolor="yellow" id="navbar">
<a href="javascript:void(0)" onclick="hideBar('navbar');">hide
menu</a><br>menu1<br>menu2<br>menu3<br>menu4
</td>
</tr>
<tr><td>lots of content here<br>more content<br>more content<br>more<br>blah<br>blah<br>blah</td>
</tr>
</table>
<table width=500>
id in div tag
<tr>
<div id="navbar2">
<td rowspan=3 bgcolor="yellow">
<a href="javascript:void(0)" onclick="hideBar2('navbar2');">hide
menu</a><br>menu1<br>menu2<br>menu3<br>menu4
</td></div>
</tr>
<tr><td>lots of content here<br>more content<br>more content<br>more<br>blah<br>blah<br>blah</td>
</tr>
</table>
</body>
</html>

Following leaves one line of background expand gif. Moving the gif outside the div throws off cell alignment. Realize that tables are no longer considered best practice but redoing table structure of whole site would be large undertaking.
<html>
<head>
<script type="text/javascript">
function toggleBar(obj) {
var navbar = document.getElementById("navbar");
if (navbar.style.display == "none") {
navbar.style.display = "";
obj.innerHTML = "<img src='images/collapse.gif' alt='Hide Menu'>";
} else {
navbar.style.display = "none";
obj.innerHTML = "<img src='images/expand.gif' alt='Show Menu'>";
}
}
</script>
</head>
<body>
<body><table><tr><td valign="top">
<div style="background-color:lightgrey;text-align:left;padding-left:4px;width:80px;">
<a href="javascript:void(0)" onclick="toggleBar(this);"><img src="images/collapse.gif"
alt="Hide Menu"></a>
<div id="navbar">menu1<br>menu2<br>menu3<br>menu4</div>
</div>
<td valign="top"><table><tr style="background-color:blue;"><td><font
color="white">Title</font></td></tr>
<tr><td>Body Text</td></tr></table>

jQuery hover stops working after a few seconds?

I am new to programming and am mostly just playing around with HTML and JavaScript right now. I recently learned about jQuery and was trying to use it in a periodic table quiz page I made. I wanted to be able to mouse over certain elements and see a relevant picture and then mouse off and restore it to the element symbol and name that was there before. Here is my code:
The element is in a table coded by HTML, like so:
<table id="ptable" style="text-align:center;">
<tr>
<td>
<div id="einsteinium"><span style="font-size:32px;">Es</span>
<p style="font-size:12px;">Einsteinium</p>
</div>
</td>
<td>hydrogen</td>
<td>helium</td>
</tr>
</table>
And here is the jQuery:
$(document).ready(function () {
var oldhtml = "";
oldhtml = $("#einsteinium").html();
$("#einsteinium").hover(function () {
$("#einsteinium").html("<img src=\"http://images.mentalfloss.com/sites/default/files/styles/insert_main_wide_image/public/einstein1_7.jpg\" height=\"70px\" width=\"70px\">");
},
function () {
$("#einsteinium").html(oldhtml);
});
});
Fiddle
The problem is that the picture of Einstein will get stuck and won't return to the element symbol/name. On the fiddle, if you keep mousing over it, it will start working again, but it doesn't do that on my code. For me, when it gets stuck it doesn't get unstuck (but the fiddle does get stuck too, and I don't want that to happen at all). I have tried changing the z-index of the div and table, but no luck there. I'd really appreciate any help!
The problem is because, you are changing the contents of the hovering div, which is messing up the mouse enter/leave events
You can do it without any javascript, but with css and the :hover selector like
#einsteinium > img {
display: none;
}
#einsteinium:hover > img {
display: inline-block;
}
#einsteinium:hover > div {
display: none;
}
<table id="ptable" style="text-align:center;">
<tr>
<td>
<div id="einsteinium">
<img src="http://images.mentalfloss.com/sites/default/files/styles/insert_main_wide_image/public/einstein1_7.jpg" height="70px" width="70px">
<div>
<span style="font-size:32px;">Es</span>
<p style="font-size:12px;">Einsteinium</p>
</div>
</div>
</td>
<td>hydrogen</td>
<td>helium</td>
</tr>
</table>

How do I have swipe left delete swipe right edit buttons off canvas?

I might redefine what the buttons do when they are clicked but that is irrelevant. I do not need help setting up ng-click events come on people. That part is easy. I am struggling big time getting the animation effects that I want. The application is in ionic so naturally I am working toward an AngularJS solution all of the examples out there are just a bit off.
I manged to piece together information and construct this:
<!doctype html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Swipe left to delete implementation using AngularJs</title>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.3.15/angular.min.js"></script>
<script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.3.15/angular-touch.js"></script>
<script type="text/javascript">
var app = angular.module('ngSwipeLeftExample', ['ngTouch']);
app.controller('SampleSwipe', ['$scope', '$window', function($scope, $window) {
// $scope.swipeLeft=false;
// $scope.swipeRight=false;
$scope.delete = function() {
alert('bbb');
// $scope.swipeLeft=true;
// $scope.swipeRight=true;
}
$scope.edit = function() {
alert('aaa');
// $scope.swipeLeft=true;
// $scope.swipeRight=true;
}
$scope.clickedTable = function() {
// alert('clicked table');
// $scope.swipeLeft=false;
// $scope.swipeRight=false;
}
}]);
</script>
</head>
<body ng-app="ngSwipeLeftExample" ng-controller="SampleSwipe">
<table ng-init="swipeLeft = false; swipeRight = false;" data-ng-swipe-right="swipeRight = true" data-ng-swipe-left="swipeLeft = true" data-ng-click="" border=1 width="100%">
<tr>
<td width="100px">
<div ng-show="swipeRight" >
<button ng-click="edit()" style="height: 44px;width: 109px;border: 0;background-color: green; color: white;font-size: 18px;font-weight: bold;cursor:pointer;">Edit</button>
</div>
</td>
<td>
<div ng-click="clickedTable()">
<table>
<tr>
<td>aaaa</td><td>bbbb</td><td>cccc</td>
</tr>
<tr>
<td>aaaa</td><td>bbbb</td><td>cccc</td>
</tr>
</table>
</div>
</td>
<td width="100px">
<div ng-show="swipeLeft" >
<button ng-click="delete()" style="height: 44px;width: 109px;border: 0;background-color: red; color: white;font-size: 18px;font-weight: bold;cursor:pointer;" align="right">Delete</button>
</div>
</td>
</tr>
</table>
</body>
</html>
But I don't really want to ng-hide the buttons I just want to size the record so that the html block in the middle column (I will put whatever in there it doesn't really matter what I put in there) should be sized to fit the page (width=100% I guess) Then the edit and delete buttons being off canvas can be swiped left or right so the user can see them and click them. I think this can be done with transitions somehow. But nothing seems to work. I am really not a CSS guy at all mostly I just piece my css together to get something almost what I want and then hand it over to my UI guy to fix it. But he doensn't know how to do this either.
It seems like most ios and android apps work this way when there is a list and you swipe left to delete but it seems nobody wants to share the wisdom of how to do this correctly.
Let me guess soeone will reply that you are confused about my question and do not know what I am asking even though it is totally clear? Correct?

iframe doesn't getting hidden using JQuery

In my page I have a div with another div and an iframe as shown below.
<div class="v_dissc_tab" id="tabs-1">
<div id="publicevent">
<div class="crtraone" style="margin-left:800px;">
<button onclick="addpublic()">Add New</button>
</div>
<div>
<table width="100%">
<tr>
<td><b>Programme</b></td>
<td><b>Scheduled Start Time</b></td>
<td><b>Scheduled End Time</b></td>
<td><b>Amount</b></td>
<td><b>Status</b></td>
<td></td>
</tr>
<tr>
<?php if($publicnum>0)
{
}
else
{ ?>
<td colspan=6>
<?php echo "No any public channel programmes";?>
</td>
<?php }?>
</tr>
</table>
</div>
</div>
<iframe id="calendarframe" style="width: 100%;height:600px;display:none;" src="<?php echo base_url()?>index.php/channel/viewbookings">
</iframe>
</div>
On page loading, the div with id publicevent will be shown and the iframe is hidden. When I click on Add New button, the iframe will be loaded. Inside iframe I am loading another page which contains a button
<button onclick="managepublic()">Manage Public Events</button>
On clicking this button, I want to show the div with id publicevent and want to hide the iframe (as when the page is firstly loaded). Shown below is managepublic().
function managepublic()
{
location.reload(); // not making any changes
//$('#publicevent').show(); Tried with this also
//$('#calendarframe').hide();
}
Can anyone help me to solve this. Thanks in advance.
dont' use location.reload ,use only following code
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js">
</script>
function managepublic()
{
$('#publicevent').show();
$('#calendarframe').hide();
}
On clicking this button, I want to show the div with id publicevent
and want to hide the iframe (as when the page is firstly loaded).
Check if this helps.
$('iframe').attr( "src", "http://www.apple.com/");
$('iframe').load(function() {
$('iframe').show()
$('#loaded').hide();
});
$('#button').click(function() {
$('#loaded').show();
$('iframe').hide();
});
JSFiddle
Try the following code snippet.
You are referring elements of <iframe>'s parent.
function managepublic(){
$('#calendarframe', window.parent.document).hide(250, function() {
$('#publicevent', window.parent.document).show();
});
}
Or
function managepublic(){
window.parent.$('#calendarframe').hide(250, function() {
window.parent.$('#publicevent').show();
});
}
Or Change the order of the hide events.
function managepublic(){
window.parent.$('#publicevent').show();
window.parent.$('#calendarframe').hide();
}
Note :
For this to work, parent must have jQuery included.
It won't work if parent is in different domain.

Javascript change div content upon a click

I'm pulling a content from PHP array and I have a situation like this:
<div class="weight-display">
<span>04/25/2011</span> <span>100lbs</span> <span>Edit</span> <a href="http://foo.com">Delete</span>
</div>
<div class="weight-display">
<span>04/27/2011</span> <span>150lbs</span> <span>Edit</span> <a href="http://foo.com">Delete</span>
</div>
etc...
Now when somebody clicks on Edit within, let's say, first div where weight is 100lbs, I just need that "div" to change and to have input field instead of simple text where weight is (while others will remain the same) and to be like this:
<div class="weight-display">
<span>04/25/2011</span> <input type="text" value="100" /> <span>Save</span> <span>Cancel</span>
</div>
<div class="weight-display">
<span>04/27/2011</span> <span>150lbs</span> <span>Edit</span> <a href="http://foo.com">Delete</span>
</div>
etc..
So basically div has to "reload itself" and change content. Now I really need some very simple Javascript solution. Preferably I would like a solution with a hidden div beneath original one, so they just swap places when user clicks on EDIT and in a case if CANCEL is pressed to swap places again so original div with text is displayed...
Thanks,
Peter
<style type="text/css">
/* Normal mode */
.weight-display div.edit {display:none}
/* Editor mode */
.weight-edit div.show {display:none}
</style>
<div class="weight-display">
<button onclick="toggle(this)">Edit this!</button>
<div class="edit"><input type="text" value="Test" /></div>
<div class="show">Test</div>
</div>
<script type="text/javascript">
function toggle(button)
{
// Change the button caption
button.innerHTML = button.innerHTML=='Edit this!' ? 'Cancel' : 'Edit this!';
// Change the parent div's CSS class
var div = button.parentNode;
div.className = div.className=='weight-display' ? 'weight-edit' : 'weight-display';
}
</script>
What you suggest is basically correct. I would generate two div's one for display and one edit. The edit div will initially have display: none. When the Edit is clicked, hide the display div and show the edit div.
How about something like:
onClick event calls a function (EDITED to be a little smarter than my original brute force method):
function swapdivs ( id_of_topdiv, id_of_bottomdiv ) {
var topdiv = getRefToDiv( id_of_topdiv );
var bottomdiv = getRefToDiv( id_of_bottomdiv );
var temp = topdiv.style.zIndex;
topdiv = bottomdiv.style.zIndex;
bottomdiv = temp.style.zIndex;
}
Could that or similar work for you? Or am I missing some subtle yet crucial requirement?

jquery .attr("alt")=='name'

Can anybody help me letting me know what is wrong with the following code?
$(document).ready(function(){
$("img").attr("alt")=='minimize'.click(function(){
alert("he");
});
});
thanks.
Addition:
Sorry guys, I am trying to add an event to a image inside of a table, so when its clicked it collapse the div under need.
I am facing several problems here.
1.- all tables and div use the same class.
2.- it may be a minimum of two tables and divs.
3.- first table should no be click able, only its images (for show and hide div under)
4.- rest of tables should be click able the whole table to show and hide div under with slidetoggle.
5.- rest of tables also have two images for show with slideDown and slideUp.
What I have it works but not fully.
Once again.
Thanks.
so far this is what I have.
<script type="text/javascript">
$(document).ready(function(){
$(".heading:not(#Container1)").click(function(){
var c = $(this).next(".container");
c.slideToggle("slow");
});
});
$(document).ready(function(){
$("img[alt='min']").click(function(){
var c = $(this).next(".container");
c.slideToggle("slow");
});
$("img[alt='max']").click(function(){
var c = $(this).next(".container");
c.slideToggle("slow");
});
});
</script>
<html>
<head></head>
<body>
<table class="heading" id="container1">
<tr>
<td>heading1</td>
<td><img alt='min'/><img alt='max'/></td>
</tr>
</table>
<div class='container'>Container1</div>
<table class="heading">
<tr>
<td>heading2</td>
<td><img alt='min'/><img alt='max'/></td>
</tr>
</table>
<div class='container'>Container2</div>
<table class="heading">
<tr>
<td>heading3</td>
<td><img alt='min'/><img alt='max'/></td>
</tr>
</table>
<div class='container'>Container3</div>
</body>
</html>
You need to use the attribute selector not get the attribute and compare it.
$(document).ready(function(){
$("img[alt='minimize']").click(function(){
alert("he");
});
});
$(document).ready(function(){
$("img[alt='minimize']").click(function(){
alert("he");
});
});
EDIT
$(function() {
$('img[alt='min'], img[alt='max']').click(function() {
var container = $(this).parent('table').next('div.container');
if ( $(this).attr('alt') == 'min' )
container.slideUp('slow');
if ( $(this).attr('alt') == 'max' )
container.slideDown('slow');
return false;
});
$('table.heading:not(:first)').click(function() {
$(this).next('div.container').slideToggle('slow');
return false;
});
});
The alt attribute is not a way to filter your images. It is designed to put alternative content for when the image cannot be displayed (not found, unwanted by user, no screen, etc.)
You should instead use the class attribute to discriminate your images the way you want.
Your code then becomes:
HTML
<img src="..." class="minimize" alt="A beautiful image">
Javascript
$(document).ready(function(){
$("img.minimize").click(function(){
alert("he");
});
});
It is not syntactically correct. What are you trying to do? Maybe this?
$(document).ready(function(){
$("img[alt=minimize]").click(function(){
alert("he");
});
});
