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.

As ever all help and advice is greatly appreciated.
Tony.
you need to call the width function
if ($(window).width() < 768) {
notice the parentheses ()

If you jumps from one page to another, every page has a different height, but they are all in one div, just they are not visible all the time.
I'm resizing the parent div everytime to the current page's height (not the full code, just a sample):
var magassag = jQuery("#post-5");
var egymagas = jQuery(".elsofo").height();
if (i == 1) {
magassag.animate({
height: egymagas
}, 100 );
}
it's working fine, but when i test it on tablet/mobile the height is ruins when i change the orientation, and i don't know why.
Use $(window).on('resize', fn) to detect window resizing.
$(window).on('resize', function() {
// re-animate the height for the current page
});
Although this works fine for tablet resizing, it will be very inefficient for desktop users who are resizing the window with their mouse. It is good to throttle the resize callback for that reason.
// Use `throttle` from any of the various throttle libraries available.
$(window).on('resize', throttle(function() {
// re-animate the height for the current page
}));
Note: I rarely use JS and jQuery so please excuse if the question is odd.
I am trying to add a div to my page (to a menu specifically) but only if the page is smaller than a certain width. Basically I need an event handler that allows me to wait for that condition to be met and run a function once it is (similar to how you would do with on.("click")) but I have no idea how to accomplish that.
Any help would be greatly appreciated!
have a look at the following code:
var $myDiv = $("<div class='myDiv'></div>");
$(window).resize(function () {
var windowWidth = $(this).width();
if (windowWidth < 200) {
$("body").append($myDiv);
} else {
$myDiv.remove();
}
});
we monitor the window resize event, and append/remove the div as per your condition.
Live Example
play around with the bottom right side of the fiddle (the result pane) and resize it to see what happens.
This is without the event handler, but you can add it in a resize event handler:
if (window.matchMedia("(min-width:700px)").matches) {
// viewport width is at least 700px
} else {
// viewport is smaller than 700px
}
hope you can help
My current project requires me to recall a set of functions on window resize so that I can keep the responsive nature correct. However the code I am using is rather twitchy as it calls the functions even if the window is resized by 1px.
I am relatively new to jQuery but learning more and more every day, but this is something I'm struggling to find a way to do.
In an ideal world I would like to call the functions when the window has been resized over a breaking point at anytime, for example:
say the breaking point is 500px, the initial load size is 400px the user resizes to 600px, so over the threshold so call the functions again.
It would also need to work in reverse... so window (or load) size 600px, breaking point 500px, resize to 400px call functions.
Here's the code I'm currently:
var windowWidth = $(window).width();
var resizing = !1;
$(window).resize(function(a) {
!1 !== resizing && clearTimeout(resizing);
resizing = setTimeout(doResize, 200);
});
function doResize() {
call_these_functions();
}
Cheers for the help guys
Thanks for the reply Zze
I am using something similar to what you've put, but I have it based within the start of my functions to filter what each thing does based on the window size. My problem is that these are getting called far too often and causing issues / twitchy behaviour.
For example I'm having issues on a tablet I'm testing on, when you scroll down, the scrollbar that appears on the right seems to trigger the window resize... causing functions to be called again that automatically accordion up or .hide() elements to their initial loaded state.
So my thinking is if I can test it's actually broken a set threshold rather than just what size the window is then it will be far more reliable.
There are some really handy jQuery functions available and it looks like you are very close to cracking this yourself. Hope this helps though.
$(window).resize(ResizeCode); // called on window resize
$(document).ready(function(e) { ResizeCode(); }); // called once document is ready to resize content immediatly
function ResizeCode()
{
if ($(window).width() < 500){
//insertCode
}
else if($(window).width() >= 500){
//insertCode
}
}
Update
If we are looking to 'restrict' the call time of this function, then you could add an interval which updates a bool every time it ticks, and then check this bool in the previous code:
var ready = true;
setInterval(function(){ready = true;}, 3000);
function ResizeCode()
{
if (ready)
{
// run code
ready = false;
}
}
But i would suggest storing the width and height of the window in a var and then comparing the current window with the var when the window is resized, that way you can tell if the window has actually been resized over 'x' amount or if it is that weird bug you've found.
Looks like i've found a solution that's going to do what i need with a little work (fingers crossed as i'm currently working on it), from http://xoxco.com/projects/code/breakpoints/

i've made a responsive website with a horizontal menu. I wanted to make the menu a toggle drop down when a lower screen resolution is reached. The JQuery-Toggle works fine and i tried this to "make it responsive":
if (document.documentElement.clientWidth < 768) {
$(document).ready(function(e){
$('#menubutton').on('click',function(){
$('#main-nav').slideToggle();
});
})
}
This works also fine but not by changing the windowsize directly in the browser – i have to resfresh the page manually to load the Script!
Is there a way to "refresh" the page when the needed screen width is reached (768 px)? …and vise versa!
thanx,
Jochen
maybe instead of refreshing the page on every resize, you can do:
var mainNavActivated = false;
$(document).ready(function(e){
$('#menubutton').on('click',function(){
if(mainNavActivated || document.documentElement.clientWidth < 768){
window.mainNavActivated=true;
$('#main-nav').slideToggle();
}
});
})
which is binding click anyway and making it work when the window is "narrow"
You can use $(window).resize(). It will call your function every time the window is resized by the user.
You can use the resize event.
$(window).resize(function() {
// here your code
});
I want a function to load only when the browser window width is greater than 940px.
I can do this on initial page load with:
if ( $(window).width() > 940) {
// my function
}
However, doing it the above way won't work on browser resize. I've been able to somewhat get it working on browser resize with the following:
$(window).resize(function() {
if ($(window).width() < 940) {
return;
}
else {
// my function
}
});
The problem with this, however, is once the function is loaded, it stays loaded whether the browser window is resized smaller or not. I need to clear the function out or un-load it whenever the window is smaller.
Is there a way to only load a function if the window is larger than 940px and completely remove it if the window is smaller than 940?
Any help would be much appreciated.
Do what you need in the first branch where you have return.
