i have a Wierd action here, i am using Meteor 0.7 (latest version), and i want to create a layout for my application where i have a menu on the left and content on the right, and i want it to be resizable, so i used Jquery UI and created teh following code.
<template name="layout">
{{> header }}
<div class="container">
<div class="report-tree">
{{> report_tree }}
</div>
<div class="content">
{{{ yield }}}
</div>
</div>
</template>
also i created this function on Meteor Client,
Template.report_tree.rendered = function (){
console.log("report_tree is rendered")
$("li.parent_li i").attr('class','glyphicon glyphicon-plus-sign');
$("li.parent_li ul li").hide();
$(".report-tree").resizable({
handles : 'e',
minWidth: '50',
maxWidth: '350',
resize: function (){
$(".content").width($(this).parent().width() - $(this).width() - 30)
}
});
$("#datepicker").datepicker();
}
the functionality is okay and reveything works fine, however when just click on an link inside my app, i can see that
console.log("report_tree is rendered")
is rendered & the date pickers is working fine, but the resizable function is not called and the div is not aboe to resize, if i clicked on teh refresh button then everything is working back again.
i dont know why this is happening and whether i need to hook my script on a different event or what ?

How can I use jquery to change the id of a div acting as a jquery mobile popup as well as the href of the anchor pointing to the popup?
In my webapp I have an anchor that, when clicked, brings up a jquery mobile popup div all of which I'm inserting dynamically. In any instance of the webapp, I don't know how many times this code will be inserted. Therefore, my understanding is that I need to be able to dynamically create a unique id for the jquery mobile popup div and set the href of my popup icon.
I am not currently succeeding at dynamically changing the id and href. I've created the following test (JSFiddle Test).
Here is my sample html:
<div class="phone1">
<p class="textLeft"> <strong>Number: </strong><span>(555)555-5555</span>
Learn more
</p>
<div id="myPopup" data-role="popup" class="ui-content" data-theme="a" style="max-width:350px;">
<p class="flagText">This number has been flagged as incorrect</p>
</div>
</div>
Change href property
Here is my sample javascript / jquery:
$('#changeButton').click(function () {
alert("Handler for .click() called.");
$('.phone1 > a').prop('href', 'myNewPopup');
$('#myPopup').attr('id', 'myNewPopup');
});
Thank you for your help in advance!
As your anchor is not a direct child of .phone1 but rather a grandchild, the > selector does not work. Also the href needs the # symbol:
$('.phone1 a').prop('href', '#myNewPopup');
Technically you should also use prop to update the id as well:
$('#myPopup').prop('id', 'myNewPopup');
Updated FIDDLE
Are you sure you need to do this. After dynamically inserting the popup the first time, you could just update it each successive time by testing if it exists in the DOM first:
if ($("#myPopup").length > 0){
//update
} else {
//create
}
I have seen variations on the theme, but no clear answer. Basically I want an AngularJS Directive that registers a click and inserts extra content into a page, and then scrolls down a bit to make the new content visible. Here is the HTML
<li class="btn btn-default" ng-show="resto.link !== 'none'">
<p scroll-down onclick="void(0)">
Full review
<span class="glyphicon glyphicon-chevron-right right"></span>
</p>
</li>
</ul>
<div class="row">
<div class="col-xs-12" ng-bind-html="fullReview">
</div>
</div>
The onlick part is an Apple suggestion, that seems not to work.
And then I have:
.directive 'scrollDown', () ->
restrict: 'A'
link: (scope, $elm, attrs) ->
$elm.on 'click', (e) ->
e.preventDefault()
scope.getFullReview () ->
console.log "Scrolling'
$("body").animate
scrollTop: $elm.offset().top - 100
, "slow"
getFullReview() updates the model after an AJAX call, and then runs the callback.
This works fine in Chrome but not on the iOS simulator - basically a first tap makes the page move (but without triggering the console log - I think this is the URL bar regrowing) and a second is needed to trigger the Directive's link function. I have also installed fastclick as that was mentioned in some posts, but it did not help.
Need ideas :-) (Even some code that would tell me what event is being triggered by safari)
OK, Wow, I do not understand why, but the html above was the last markup on the page, so all of this was happening at the bottom of the screen. When I added some extra margin to the <ul> element, everything started working perfectly!! Bug in Safari?
I've a big problem with a jQuery Mobile Application:
I'm using custom functions (they are triggered by onClick) to switch the page with currentPage.
It only happens on Android-Devices on sites in which has changed (due to ajax requests) with the integrated browser. iOS and Chrome works nice.
After clicking on an element, the animation started but just before it ends, it switches back to the old page. After a half second, it switches back to the new.
I made a movie of the bug here: http://www.youtube.com/watch?v=sXxvVUxniNg
Thank you very much
Code (CoffeeScript):
class Guide
#categoriesLoaded = false
#loadSearch: ->
$.mobile.changePage $("#guide"),
transition: 'slide'
changeHash: false
if !#categoriesLoaded
#categoriesLoaded = true
GuideApi.getCategories (data) ->
output = Mustache.render $("#tmpl-guide-categories-select").html(),
categories: data
$("#guide-search-category").append output
$("#guide-search-category").val($("#guide-search-category option:first").val());
window.WgSwitchGuide = ->
Guide.loadSearch
I was having the same issue. And I tried everything, I finally end with the solution. What I found was the error was principally within the browser. So I set the configuration of the pushStateEnabled as false. I did it by doing the following, adding this script.
<script type="text/javascript">
$(document).bind("mobileinit", function(){
$.mobile.pushStateEnabled = false;
});
</script>
It should be add before the jquery-mobile script is call, for more information you could see it on JQuery description
And it solved the problem no more jumping back.
I was having the exact same issue on both android and ios. For me, it was happening for heavy pages, i.e., pages with complex elements etc. Looks like you are using "slide" transition, which was what I was using as well. Taking out the page transitions (i.e., $.mobile.changePage("page.html", { transition: "none" })) for those pages resolved this issue for me. Hope this helps.
If you want to retain the transition, you can try preloading the page first when the previous page is being shown, by using the $.mobile.loadPage, and then show the transition. I am myself exploring this route, but it is probably worth trying.
Edit: OK - I explored the last suggestion and this doesn't seem to be working. Will stick with the first option.
Would you try to add the event stopPropagation and preventDefault methods on the first page's click event? This way the default action of the click event will not be triggered. Moreover the stopPropagation prevents the event from bubbling up the DOM tree, preventing any parent handlers from being notified of the event.
event.stopPropagation();
event.preventDefault();
Example:
$("p").click(function(event){
event.stopPropagation();
event.preventDefault();
// change page
});
After trying for weeks to find a solution to this, I ended up doctoring the JQM library to disable page transitions one right after another. It's not a good solution, but it's the only thing I could get to work.
I was getting pages jumping back on both $.mobile.changePage and on anchor links. I used the slide transition, but removing it did not fix the problem. Setting pushStateEnabled to false did not work either. The jumps were happening on all devices and browsers (that I tested, anyway).
So here's what I did to the JQM library (v1.3.2).
Before the $.mobile.changePage function is defined, I added:
var justChangedPage = false;
Then within the function there's a line that goes:
if ( pbcEvent.isDefaultPrevented()) {
return;
}
which I changed to:
if ( pbcEvent.isDefaultPrevented() || justChangedPage) {
return;
}
Then right after this part of the $.mobile.changePage function:
if ( toPage[ 0 ] === $.mobile.firstPage[ 0 ] && !settings.dataUrl ) {
settings.dataUrl = documentUrl.hrefNoHash;
}
I added:
justChangedPage = true;
setTimeout(function() {
justChangedPage = false;
}, 500);
(Putting that earlier in the function didn't work -- all that stuff executes more than once within a single page transition. And half a second seemed to be the minimum timeout that prevented the page jumps.)
I hope this helps someone even if it is a hack...
What is your JQM and Android version?
I'm not sure If I understand correctly. I think transition flicker maybe come from the following assumption.
Heavy page DOM transition.
Using "translate3d" somewhere in css file.
Not using "H/W Acceleration" feature. Enable by add this line to your AndroidManifest.xml in <application>
android:hardwareAccelerated="true"
I encountered exactly the same behaviour and it seems that few people are having the same issue. At first I thought it is caused by jQuery mobile library. Later on, I manage to find where the problem came from and it is a bug in my own code.
I made a demo to explain the issue.

Hopefully, this can be hint for people having the same problem.

I am developing the application using jQuery Mobile 4.1.
In my app, I have two html pages like login.html and home.html. In the home.html have 3 pages. () like menupage, searchpage, resultpage.
The project flow is login.html ---> home.html. In home.html, menupage is displayed as a first page. If I choose the some option in the menupage it will move to searchpage and then resultpage. consider, currently I am in the resultpage. If I press the back button on the mobile browsers (iPhone-safari, Android-chrome) then it moves to the login.html.
But I want to display the searchPage. How to solve this one? is it possible to do this?
[Note : The pages should be in the single html page(home.html).
use the attribute data-rel="back" on the anchor tag instead of the hash navigation, this will take you to the previous page
Look at back linking: Here
Newer versions of JQuery mobile API (I guess its newer than 1.5) require adding 'back' button explicitly in header or bottom of each page.
So, try adding this in your page div tags:
data-add-back-btn="true"
data-back-btn-text="Back"
Example:
<div data-role="page" id="page2" data-add-back-btn="true" data-back-btn-text="Back">
try
$(document).ready(function(){
$('mybutton').click(function(){
parent.history.back();
return false;
});
});
or
$(document).ready(function(){
$('mybutton').click(function(){
parent.history.back();
});
});
You can try this script in the header of HTML code:
<script>
$.extend( $.mobile , {
ajaxEnabled: false,
hashListeningEnabled: false
});
</script>
You can use nonHistorySelectors option from jquery mobile where you do not want to track history. You can find the detailed documentation here http://jquerymobile.com/demos/1.0a4.1/#docs/api/globalconfig.html
This is for version 1.4.4
<div data-role="header" >
<h1>CHANGE HOUSE ANIMATION</h1>
Back
</div>
try to use li can be more even
<ul>
<li>back</li>
</ul>
I am using the new v3 of the Google Maps API. Basically the issue I have is that I have a Google Map within jQuery UI Tabs. The map is not in the first tab, so you have to click the tab to view the map, but it does not always render correctly. I.e. sometimes the map images are not correctly placed.
I had this problem when I was using v2 of the API, but I managed to resolve the problem by initializing my Map like this:
map = new GMap2(document.getElementById("map"),{size:new GSize(500,340)});
Unfortunately that doesn't work in v3. I had a look at the suggestions in this thread: Problems with Google Maps API v3 + jQuery UI Tabs
Nothing really worked for me, but I used one of the workarounds in that I initialize the map function on tab load:
$(function()
{
$("#tabs-container").tabs({show: function(event, ui)
{
if(ui.panel.id == "viewmap")
{
mapiInitialize();
}
}});
});
This is all good but I much rather prefer for the map to be "there" when the user clicks on the tab. It sometimes takes a few seconds for the map to load up and all the user see's in that time is a plain gray background - some sort of loading indicator might have helped.
So does anybody have any suggestions? My markup and CSS is as follows:
<div id="tabs-container">
<ul>
<li><span>Details</span></li>
<li><span>Location Map</span></li>
<li><span>Reviews (<?php echo $numrows; ?>)</span></li>
</ul>
<div id="details"><?php echo $details; ?></div>
<div id="viewmap" style="padding: 10px; border: 1px solid #A9A9A9;">
<div id="map" style="height: 340px;"></div>
</div>
<div id="reviews"><?php echo $reviews; ?></div>
</div><!-- end tab-container -->
Try this when you are initializing your jQuery UI tabs:
$("#tabs-container").tabs({
show: function(event, ui) {
google.maps.event.trigger(map, 'resize');
}
});
Note: You will have to initialize the map before you initialize the tabs.
Once you switch to the tab that has the map call google.maps.events.trigger(map, 'resize'); that should then make it display correctly.
just use
map.setZoom( map.getZoom() );
