I am using a mixture of jQueryTools overlay (lightbox type thing) and a scroll-bar called Perfect Scrollbar. The problem I have is that when the overlay is loaded the scroll-bar doesn't show until you scroll within that box. I need to be able to make it clearer so that everyone knows it is a scroll-able content box. One way this could be possible is to make the content box scroll up one pixel when the overlay is opened. I have found the following code
$(".scroll-content").load(function() {
window.scrollBy(0,-1);
}
which I have been told should work but no matter what I can't get it to scroll at all.. Is there something i'm doing wrong?
Since you have the scroll bar method bind to an element that is initially in a 'hide' status, in fact .BigSuperBlock .block_overlay is hidden by display:none; in Css, the plugin can not properly calculate the height of the overlay container.
So, when you call the function that show-up the 'overlay' container, you have to call the method on the scroll-content class:
$('.scroll-content').perfectScrollbar('update');
You can find the documentation of this in the author's page.
To make it works, you have to call the plugin 'update' method, again, in the jQueryTools modal function, as a callback.
$(".block_overlay").overlay({
onLoad: function(event) {
$('.scroll-content').perfectScrollbar('update');
// here you update the perfectScrollbar plugin
},
onClose: function(event) {
// other custom code
}
});
Try with this:
jQuery("container").animate({ scrollTop: 50 }, 800);
Give that you want to make clear that there is a scrollbar, you can have it on all the time if you change the perfect-scrollbar.css
.ps-container .ps-scrollbar-x-rail {
...
opacity: 0.6;
}
.ps-container .ps-scrollbar-y-rail {
...
opacity: 0.6;
}

I'm using jQuery UI to create a tooltip for a search input field. I then want to position the tooltip according to the size of the browser window (top if less than 768px, left if more).
I initialise the tooltip with:
$('#search').tooltip({'placement':'top'});
Then I have this function to change the placement depending on the window size:
$(window).on('resize', function() {
if ($(window).width < 768) {
$("#damSearch").tooltip({'placement':'top'});
} else {
$("#damSearch").tooltip({'placement':'left'});
}
}).trigger('resize');
For some reason it's not working. The tooltip initialises fine but when I resize the browser above 768px it still appears positioned to the top.
[EDIT]
I've been away for a few days and have just come back to try and resolve this problem.
I've installed Modernizr because I intend using it elsewhere on the site and so I thought I'd use Modernizr.mq to detect the window resizing. I also read elsewhere that the code to reposition the tooltip should be in its own self contained function, so this is the function:
function positionTooltip() {
if (Modernizr.mq('(min-width: 768px)')) {
$("#damSearch").tooltip({'placement':'left'});
} else {
$("#damSearch").tooltip({'placement':'bottom'});
}
}
This is then followed in my Javascript file with:
$(document).ready(function() {
positionTooltip();
// Fire the function on page load
$(window).resize(positionTooltip);
// Fire function on window resize event
Unfortunately it's still not working correctly.
The tooltip appears correctly positioned when the page is first loaded, but if I then resize the browser the position is not updated. If I reload the page however the tooltip's position is changed accordingly.
It's as if the resize event is not triggering the function.
[/EDIT]
As ever all help and advice is greatly appreciated.

you need to call the width function
if ($(window).width() < 768) {
notice the parentheses ()
I am trying to edit this code for my website. Right now, on hover it activates an overlay on the image. I want to add to it so that in addition to activating the overlay it also changes the background color of the body. Can this be done within this code or is this more work than I think? Thanks!
jQuery('.images').hoverIntent(function() {
jQuery(this).find('.title-wrap').stop().each(function() {
jQuery(this).animate({
width: jQuery(this).data('wrapping')
}, 150);
});
One way to configure hoverIntent is with 2 functions as arguments .... one for each of mouseenter and mouseleave.
For the body just toggle a class and set the background in a css rule
function hoverIn(){
$('body').addClass('different-background-class');
jQuery(this).find('.title-wrap').stop().each(function() {
jQuery(this).animate({
width: jQuery(this).data('wrapping')
}, 150);
}
function hoverOut(){
$('body').removeClass('different-background-class');
jQuery(this).find('.title-wrap').stop().width('auto');
}
// pass the 2 function references as arguments
jQuery('.images').hoverIntent(hoverIn,hoverOut);
I'm not sure if you have width defined prior to this animation. If so we can store the initial value within hoverIn() function in order to reset it in hoverOut(). I used auto assuming it wasn't set in normal state
I have a menu that is hidden from view (for mobile) using CSS:
#filter-column {
position:absolute;
left:-400px;
}
When the user clicks a link I want to hide everything else except that menu which will slide in from the left. I want the reverse to happen when the layer is closed.
I have the following jQuery:
// Show/hide filters on mobile //
$("#openMobileFilters").click(function(){
$("#filter-column").animate({left:'0'},600).css('position', 'relative');
$('#results-container, #footer').addClass('hidden-xs');
});
$(".closeFilters").click(function(){
$("#filter-column").animate({left:'-400px'},600).css('position', 'absolute');
$('#results-container, #footer').removeClass('hidden-xs');
});
The problem is when I click to hide the menu the content shows before it is actually hidden. Is there a better way of doing this?
Without seeing this in action in a fiddle, I can only suggest you move the removal of the hidden class to the complete function of animate
$(".closeFilters").click(function(){
$("#filter-column").animate({left:'-400px'}, 600, function() {
$('#results-container, #footer').removeClass('hidden-xs');
}).css('position', 'absolute');
});
Currently, you are showing the content while the animation is going on which is why you see the content right away.
you have to put the code you want to be executed after the animation in the complete callback .. for example:
$("#filter-column").animate({
left:'-400px',
complete: function() {$('#results-container, #footer').removeClass('hidden-xs');}
}, 600)
I was having an issue where a flot graph would not render in a tabbed interface because the placeholder divs were children of divs with 'display: none'. The axes would be displayed, but no graph content.
I wrote the javascript function below as a wrapper for the plot function in order to solve this issue. It might be useful for others doing something similar.
function safePlot(placeholderDiv, data, options){
// Move the graph place holder to the hidden loader
// div to render
var parentContainer = placeholderDiv.parent();
$('#graphLoaderDiv').append(placeholderDiv);
// Render the graph
$.plot(placeholderDiv, data, options);
// Move the graph back to it's original parent
// container
parentContainer.append(placeholderDiv);
}
Here is the CSS for the graph loader div which can be placed
anywhere on the page.
#graphLoaderDiv{
visibility: hidden;
position: absolute;
top: 0px;
left: 0px;
width: 500px;
height: 150px;
}
Perhaps this is better solution. It can be used as a drop in replacement for $.plot():
var fplot = function(e,data,options){
var jqParent, jqHidden;
if (e.offsetWidth <=0 || e.offetHeight <=0){
// lets attempt to compensate for an ancestor with display:none
jqParent = $(e).parent();
jqHidden = $("<div style='visibility:hidden'></div>");
$('body').append(jqHidden);
jqHidden.append(e);
}
var plot=$.plot(e,data,options);
// if we moved it above, lets put it back
if (jqParent){
jqParent.append(e);
jqHidden.remove();
}
return plot;
};
Then just take your call to $.plot() and change it to fplot()
The only thing that works without any CSS trick is to load the plot 1 second after like this:
$('#myTab a[href="#tabname"]').on("click", function() {
setTimeout(function() {
$.plot($(divChartArea), data, options);
}, 1000);
});
or for older jquery
$('#myTab a[href="#tabname"]').click (function() {
setTimeout(function() {
$.plot($(divChartArea), data, options);
}, 1000);
});
The above example is applied to Bootstrap tags for Click funtion. But should work for any hidden div or object.
Working example: http://topg.org/server-desteria-factions-levels-classes-tokens-id388539
Just click the "Players" tab and you'll see the above example in action.
This one is a FAQ:
Your #graphLoaderDiv must have a width and height, and unfortunately, invisible divs do not have them. Instead, make it visible, but set its left to -10000px. Then once you are ready to show it, just set it's left to 0px (or whatever).
OK, I understand better now what you're actually saying... I still think your answer is too complicated though. I just tried this out using a tabbed interface where the graph is in a hidden tab when it's loaded. It seems to work fine for me.
http://jsfiddle.net/ryleyb/dB8UZ/
I didn't have the visibility:hidden bit in there, but it didn't seem necessary...
You could also have visibility:hidden set and then change the tabs code to something like this:
$('#tabs').tabs({
show: function(e,ui){
if (ui.index != 2) { return; }
$('#graphLoaderDiv').css('visibility','visible');
}
});
But given the information provided, none of that seems particularly necessary.
I know this is a bit old but you can also try using the Resize plugin for Flot.

It is not perfect because you'll sometimes get a flash of the non-sized graph which may be shrunk. Also some formatting and positioning may be off depending on the type of graph that you are using.
I'm using the SimpleModal Jquery plugin and it works great!
However, there are times that the width and height of the modal div need to be changed, so I need the modal to automatically re-position itself in the center of the page. I found out that SimpleModal uses its setPosition() function to do this. It is automatically called when the modal is launched.
So I tried to call the said function when the modal div's dimensions change, but it doesn't work:
$('#mybutton').click(function() {
//code here to resize the modal
$.modal.impl.setPosition(); //doesn't work. note that at this point, the modal is still active (displayed)
});
Do you have any ideas?
In the current version (1.3.5), you can re-position the dialog in the callback. For example:
$('#foo').modal({
onShow: function (dialog) {
var modal = this; // you now have access to the SimpleModal object
// do stuff here
// re-position
modal.setPosition();
}
});
I'm working on version 1.3.6 which will provide some convenience methods for these "utility" functions.
When you make an element (let's call it theElement) into a modal, it will be wrapped by a div#simplemodal-container. div#simplemodal-container will get the same dimentions as theElement (in fact, it will be 2px higher/wider than theElement)
You don't say what element you are actually resizing, but I guess it's theElement. If that's the case, #simplemodal-container's dimentions aren't updated, and positioning it again will have no effect. You have to resize the container explicitly.
Therefore, after resizing and before positioning again, do this:
$("#simplemodal-container").css({height: newHeight, width: newWidth});
Here i assume newHeight and newWidth is theElement's new dimentions (+2 if you want to follow simplemodal's policy)
This works for me:
var modal = $.modal("<div>...</div>");
$('#mybutton').click(function() {
//code here to resize the modal
modal.setPosition();
});
