So I was using static pages until I decided to migrate over to Rails for use in my web app.
I was able to effectively create a sticky footer with the following codePen:
http://codepen.io/aetles/pen/jAdzw
$(function(){ $(document).foundation(); });
window.onload = function() {
stickyFooter();
};
function checkForDOMChange() {
stickyFooter();
}
//check for resize event if not IE 9 or greater
window.onresize = function() {
stickyFooter();
}
//lets get the marginTop for the <footer>
function getCSS(element, property) {
var elem = document.getElementsByTagName(element)[0];
var css = null;
if (elem.currentStyle) {
css = elem.currentStyle[property];
} else if (window.getComputedStyle) {
css = document.defaultView.getComputedStyle(elem, null).
getPropertyValue(property);
}
return css;
}
function stickyFooter() {
console.log("sticky footer is firing");
if (document.getElementsByTagName("footer")[0].getAttribute("style") != null) {
document.getElementsByTagName("footer")[0].removeAttribute("style");
}
if (window.innerHeight != document.body.offsetHeight) {
var offset = window.innerHeight - document.body.offsetHeight;
var current = getCSS("footer", "margin-top");
if (isNaN(current) == true) {
document.getElementsByTagName("footer")[0].setAttribute("style","margin-top:0px;");
current = 0;
} else {
current = parseInt(current);
}
if (current+offset > parseInt(getCSS("footer", "margin-top"))) {
document.getElementsByTagName("footer")[0].setAttribute("style","margin-top:"+(current+offset)+"px;");
}
}
}
However, when I deploy it into a real-time application utilizing Rails, the event itself is getting fired (I tested with console.log messages) but it doesn't actually edit the position of the footer.
(view console in the following page)
https://still-plains-7660.herokuapp.com/
Because I'm using a partial for the footer itself, could it be that Rails doesn't know what to actually move? The source code on the rendered page looks as it should.
Is there a more elegant gem or solution I can utilize to have a sticky footer that does not have a fixed height? (I need it responsive).
Considering it works fine on a static page, I'm sure there is something I can just tweak but I can't seem to figure out why it won't stick in a Rails deployment.
I cannot remember what exactly I did when I created sticky footer using Foundation. But I think I found some solution for you.

I am trying to have a div show if an option is selected using the Select2 plug in.
I tried using the following code but it does not work:
$(document).ready(function() {
var h = $(".shipment-details--other-description");
$("#shipment-details-select-pacakage-types").change(function() {
if (this.checked && this.value == "Other") {
h.show();
} else {
h.hide();
}
}).change()
});
The div is being hid but not being shown if the Other option is selected.
Is there a different way to do this with Select2?
Edit: Forgot to mention that this a multiple select field. Also, adjusted the code and took out the this.checked as that was for a check field.
try to create a new css class, is-hidden{ display:none;}
$(document).ready(function() {
var h = $(".shipment-details--other-description");
$("#shipment-details-select-pacakage-types").change(function() {
if (this.checked && this.value == "Other") {
h.addClass('is-hidden');
} else {
h.removeClass('is-hidden');
}
}).change()
});
I know this has been asked before but I can't get any of he examples to work.
Getting the slide transition to work where you have all the pages as separate html files seems very difficult to do? How does the next/prev part of the script know which of the other files is next?
For example, index.html should slide to 01_welcome.html - but how does it know that it's not 02_funds.html?
Thanks for any enlightenment you can give. Below is the script ( courtesy of a previous answer) I've been trying to implement.
$('div.ui-page').live("swipeleft", function () {
var nextpage = $(this).next('div[data-role="page"]');
if (nextpage.length > 0) {
$.mobile.changePage(nextpage, "slide", false, true);
}
});
$('div.ui-page').live("swiperight", function () {
var prevpage = $(this).prev('div[data-role="page"]');
if (prevpage.length > 0) {
$.mobile.changePage(prevpage, {
transition: "slide",
reverse: true
}, true, true);
}
});
The code in your OP works well in Multi-Page Model environment, since all pages (div's) are present in DOM. For Single Page Model, you will need to tweak the code a bit as each page is an individual file. Another note, .live() is deprecated, use .on() instead.
The simplest solution is to add custom attributes to each page div, e.g.
<div data-role="page" data-next-page="services" data-prev-page="about">
Retrieve the values of the custom attributes on swipe and then load the target page.
$(document).on("swipeleft swiperight", function (event) {
var activePage = $.mobile.pageContainer.pagecontainer("getActivePage"),
nextPage = activePage.data("next-page"),
prevPage = activePage.data("prev-page");
/* move to next page */
if (event.type == "swipeleft" && nextPage) {
$.mobile.pageContainer.pagecontainer("change", nextPage + ".html");
}
/* move to previous page */
if (event.type == "swiperight" && prevPage) {
$.mobile.pageContainer.pagecontainer("change", prevPage + ".html", {
reverse: true
});
}
});
I use endless scrolling in my rails 4 application.
The code automatically updates the url when I scroll a list:
var loading = false;
$(function() {
function nearBottomOfPage() {
return $(window).scrollTop() > $(document).height() - $(window).height() - 200;
}
$(window).scroll(function(){
if (loading || $(".infinite-scroll").length == 0) {
return;
}
if(nearBottomOfPage()) {
loading=true;
var qstring = parseInt(getParameterByName('page'));
if(isNaN(qstring)) {qstring = 1;}
qstring++
updateQueryString('page',qstring);
var url = $(".infinite-scroll").data("update-url")
var q_string = window.location.search
if(url.indexOf("?") != -1) {
q_string = q_string.replace("?","&")
}
url = url + q_string
$.ajax({
url: url,
type: 'get',
dataType: 'script',
success: function() {
$(window).sausage('draw');
loading=false;
}
});
}
});
$(window).sausage();
});
The updateQuerystring function replaces the state like so:
window.history.replaceState({turbolinks: true, position: Date.now()}, document.title, new_url);
This is a hack to try to get something that worked in rails 3 to work in rails 4...
It seems to work but it is not clean and has some issues.
The main issue is the fact that the scroll position is not reminded. When clicking the back button, I come back to the top of the page.
Is there a way to do this cleaner. Ideally, instead to do window.history.replaceState I'd like to do Turbolinks.replaceState(newUrl) or something like that.
But if I could find a way to remember the scroll position, It would be great already.
Thank you!
Triggering a Turbolinks visit manually
You can use Turbolinks.visit(path) to go to a URL through Turbolinks.

In one file, I have
go
In t2.html I have
<script>
document.write(window.opener);
</script>
On Safari on iOS, and on Chrome on the Mac and on pretty much every other browser, it prints out [object Window] like you'd expect.
On Chrome on iOS, I get null.
How do I get to the window that opened this window?
This code solves the problem you are talking about (specifically for issues with Chrome ios not liking "pop ups"), but in reference to Paypal Adaptive Payments where it opens a "pop up" and redirects to Paypal page for payment.
The key is that you have to:
Initiate the window.open directly from a button/link click
You must use the _blank as the window "name" (and not choose your own)
The main thing you want/need is:
var win;
//VERY IMPORTANT - You must use '_blank' and NOT name the window if you want it to work with chrome ios on iphone
//See this bug report from google explaining the issue: https://code.google.com/p/chromium/issues/detail?id=136610
win = window.open(paypalURL,'_blank');
//Initiate returnFromPayPal function if the pop up window is closed
if (win && win.closed) {
returnFromPayPal();
}
Here is the full code that you can follow (ignore anything that doesn't apply to what you are doing).
<div>
<?php $payUrl = 'https://www.paypal.com/webapps/adaptivepayment/flow/pay?expType=mini&paykey=' . $payKey ?>
<button onclick="loadPayPalPage('<?php echo $payUrl; ?>')" title="Pay online with PayPal">PayPal</button>
</div>
<script>
function loadPayPalPage(paypalURL)
{
var ua = navigator.userAgent;
var pollingInterval = 0;
var win;
// mobile device
if (ua.match(/iPhone|iPod|Android|Blackberry.*WebKit/i)) {
//VERY IMPORTANT - You must use '_blank' and NOT name the window if you want it to work with chrome ios on iphone
//See this bug report from google explaining the issue: https://code.google.com/p/chromium/issues/detail?id=136610
win = window.open(paypalURL,'_blank');
pollingInterval = setInterval(function() {
if (win && win.closed) {
clearInterval(pollingInterval);
returnFromPayPal();
}
} , 1000);
}
else
{
//Desktop device
var width = 400,
height = 550,
left,
top;
if (window.outerWidth) {
left = Math.round((window.outerWidth - width) / 2) + window.screenX;
top = Math.round((window.outerHeight - height) / 2) + window.screenY;
} else if (window.screen.width) {
left = Math.round((window.screen.width - width) / 2);
top = Math.round((window.screen.height - height) / 2);
}
//VERY IMPORTANT - You must use '_blank' and NOT name the window if you want it to work with chrome ios on iphone
//See this bug report from google explaining the issue: https://code.google.com/p/chromium/issues/detail?id=136610
win = window.open(paypalURL,'_blank','top=' + top + ', left=' + left + ', width=' + width + ', height=' + height + ', location=0, status=0, toolbar=0, menubar=0, resizable=0, scrollbars=1');
pollingInterval = setInterval(function() {
if (win && win.closed) {
clearInterval(pollingInterval);
returnFromPayPal();
}
} , 1000);
}
}
var returnFromPayPal = function()
{
location.replace("www.yourdomain.com/paypalStatusCheck.php");
// Here you would need to pass on the payKey to your server side handle (use session variable) to call the PaymentDetails API to make sure Payment has been successful
// based on the payment status- redirect to your success or cancel/failed page
}
</script>
This seems to be a bigger story. See Bugtracker here:
http://code.google.com/p/chromium/issues/detail?id=136610&q=window.opener&colspec=ID%20Pri%20Mstone%20ReleaseBlock%20OS%20Area%20Feature%20Status%20Owner%20Summary
But it seems, as if iframes could handle the parent-property, so maybe you could switch your app from using popups to using an overlay.
If you want to pass values from child to parent use the following code.
Add following code to parent page:
var hidden, state, visibilityChange;
if (typeof document.hidden !== "undefined") {
hidden = "hidden";
visibilityChange = "visibilitychange";
state = "visibilityState";
} else if (typeof document.mozHidden !== "undefined") {
hidden = "mozHidden";
visibilityChange = "mozvisibilitychange";
state = "mozVisibilityState";
} else if (typeof document.msHidden !== "undefined") {
hidden = "msHidden";
visibilityChange = "msvisibilitychange";
state = "msVisibilityState";
} else if (typeof document.webkitHidden !== "undefined") {
hidden = "webkitHidden";
visibilityChange = "webkitvisibilitychange";
state = "webkitVisibilityState";
}
// Add a listener that constantly changes the title
document.addEventListener(visibilityChange, function () {
if (localStorage.getItem("AccountName")) {
$("#txtGrower").val(localStorage.getItem("AccountName"));
}
if (localStorage.getItem("AccountID")) {
$("#hdnGrower").val(localStorage.getItem("AccountID"));
}
}, false);
Add following in child page (Any preferred event)
function CloseChildAndLoadValuesToParent() {
localStorage.setItem("AccountName", 'MyAccountName');
localStorage.setItem("AccountID", 'MyAccountID');
window.close();
}
I'm trying to use class names to change the color of a link after it has been selected, so that It will remain the new color, but only until another link is selected, and then it will change back.
I'm using this code that was posted by Martin Kool in this question:
<html>
<head>
<script>
document.onclick = function(evt) {
var el = window.event? event.srcElement : evt.target;
if (el && el.className == "unselected") {
el.className = "selected";
var siblings = el.parentNode.childNodes;
for (var i = 0, l = siblings.length; i < l; i++) {
var sib = siblings[i];
if (sib != el && sib.className == "selected")
sib.className = "unselected";
}
}
}
</script>
<style>
.selected { background: #f00; }
</style>
</head>
<body>
One
Two
Three
</body>
It works fine until I try to out the links in a table. Why is this? Be easy, I'm a beginner.
There is no error, the links are changing to the "selected" class, but when another link is selected, the old links are keeping the "selected" class instead of changing to "unselected". Basically, as far as I can tell, it's functioning like a vlink attribute, which is not what I'm going for.
And yes, the links are all in different cells, how would you suggest I change the code so that it works correctly?
OK, actually, I spoke too soon.
document.onclick = function(evt)
{
var el = window.event? event.srcElement : evt.target;
if (el && el.className == 'unselected')
{
var links = document.getElementsByTagName('a');
for (var i = links.length - 1; i >= 0; i--)
{
if (links[i].className == 'selected')
links[i].className = 'unselected';
}
el.className = 'selected';
}
return false;
}
This code you gave me works great, visually, it does exactly what I want it to do. However, It makes my links stop working... They change color, but dont link to anything, and then when I remove the script, they work fine. What am I doing wrong/what do I have to change to make this work?
Also, I want to do the same thing somewhere else in my website, where the links are all in one <div> tag, separated by <p> tags. How can I make this work?
You're looping through the siblings. If the links are in separate <td>'s then they're no longer siblings.
You can loop through all the links like this:
document.onclick = function(evt)
{
var el = window.event? event.srcElement : evt.target;
if (el && el.className == 'unselected')
{
var links = document.getElementsByTagName('a');
for (var i = links.length - 1; i >= 0; i--)
{
if (links[i].className == 'selected')
links[i].className = 'unselected';
}
el.className = 'selected';
}
return false;
}
I've also added a return false; at the end of the function to stop you going to '#'
Is there an error or is there just nothing happening? A good first step if you are a javascript beginner is to use a tool like Firebug so you see detailed error messages, and you can add in console.log statements to see what's going on while you run your code.
By ‘in tables’ do you mean putting each link in its own cell? Because that would make this line:
var siblings = el.parentNode.childNodes;
fail to select other links outside of the cell. You'd have to find another way to signal which element is the link container.
