JQuery :: Event Handler For Element Repositioning Via Browser Layout Change?
Mar 31, 2010
it's possible to bind a function to an element that is fired if that element is 'moved'/repositioned via the browser.
For a more specific example what I have is a function that calculates height and width of certain elements to allow them to all fit nicely on the page without having scroll bars, and this is bound to the window onresize event. It works nicely most of the time but occasionally something will change the height of one of the elements and this effectively bumps one element right off the page.
So I'm wondering if its possible to have an event bound to an element that is fired when an elements position is moved/recalculated by the browser? Short of polling every second or so, to see if it has moved/recalculate layout.
I'm trying to change a word in an animated collapsible div script from Dynamic Drive. When clicking "Hide" I want the word to change to "Show". I have part of the script, but it's not working correctly - it just removes "Hide" when clicking on it. See the example here.
The code so far is this:animatedcollapse.ontoggle=function($, divobj, state){ //fires each time a DIV is expanded/contracted //$: Access to jQuery //divobj: DOM reference to DIV being expanded/ collapsed. Use "divobj.id" to get its ID //state: "block" or "none", depending on state if ($('#'+divobj.id+'-toggle').length==1){ //if toggle link has id 'divid-toggle' defined if (state=="block") $('#'+divobj.id+'-toggle').prepend('<span class="prefix">Hide </span>') else $('#'+divobj.id+'-toggle').find('span.prefix').remove() }} I'm totally new to jQuery.
Its a very convoluted title, but not sure how to phrase it.I'm using the latest version of jquery. i have a function that creates a new row given an onchange event for the primary select box. This new row contains another drop down box that i want to bind another onchange event. Problem is when the child drop down change event is triggered, if there are multiple children, the alert pops up for the number of children that it has.. horrible explanation heres the code:
Code: $('#perph_type').change(onSelectChange); function onSelectChange(){
I'm trying to write a cross-browser (IE and firefox) event handler for the mousewheel. Basically my web app is an image viewer, so if you scroll "down" with the wheel the next image should be displayed and if you scroll "up" the previous image should be displayed.
So far I have:
function handleMouseWheel(e) { if (!e) e = window.event;
I am trying to develop a Qwerty Shifter http:[url]....by handling keyboard events.I want to display a textbox and as user type any text it changes at once means as user types "a" it display "s" "b" changes "n"
The table, and the input id element, are dynamically created from database records and I use jQuery live to initialize the datepicker for each field, like so:
The idea is that when I click in the input field, the datepicker pops up and allows the user to input a date. While the date shows in the input field in the table, the value attribute of the input field is empty. I can't use the getDate() method on the datepicker, since I can't programmatically connect the datepicker element in any particular row with the input element in that row. I tried the onClose method shown below, but that doesn't work either. Has anyone done this successfully?
I want to change the event handler for a form field, using JS code. But there doesn't seem to be a way to reference it. MyForm.SomeField.onChange is undefined. Anyone know if there's a way to do this?
I'm having a problem in identifying the current element. I have a for loop, within which i'm creating a 'TD' and then a 'A' (anchor). I have added an eventListener (onclick event) to the <a>, which invokes a method. The problem is i'm unable to identify on which <a> the user has clicked. extracted code:
Code: for(i=0; i < count; i++) { .... .... var td2=document.createElement('TD'); // Add title var title = document.createElement("a"); [Code]...
Does jquery have an event defined for when the user changes the size of his browser window? I couldn't find one, but sometimes I don't see the forest for the trees.
I have created some code that alerts me the contents of all the child divs inside a main div
function CheckEventLayout(){ //check all divs in area and resize overlapping divs var RunOnce; if( RunOnce != true ){ var StartTimes = new Array(); var EndTimes = new Array(); var i = 0; $("div#day-view-overlay").children("div.day-view-appointment").each(function(){ var DoOnce; if( DoOnce != true ){ alert($(this).html()); ..... CheckEventLayout();
The problem is this code is on a page that is loaded via post and if you go off the page and then back onto it jquery seems to attach the function again so it runs twice. So need to unbind this function before the script runs again.
using JQuery 1.3.2.js How can i bind change event of future added drop-down. i have even used ".live" method of jQuery but it doesn't work.I have even updated JQuery1.3.2.js to JQuery 1.4.js but same thing happens drop down change event is not getting fired but click and other events are getting fired.
I have an XHTML STRICT page which has some event listeners attached for onload and resize. I'm doing a bit of Javascript DHTML on these events. When a user changes the browser font size, the javascipt function needs to run. Although the TOPMENU DIV gets resized when the font changes size, its not a page resize so the function doesn't get run. I fixed this in IE6 by using a second function which is run onload and sets an event on the div object in the page after its been defined.
Problem is this doesn't work in Firefox.
Mozilla DOM reference says there is no resize event on a DIV so is there a work around to make it work in FIREFOX? i.e. can I force a resize event to happen on a div in firefox or is there some other event I can trap when a user changes the browser font size?
here's my js code: topmenu is what I'm trying to trap the resize event from.
I've many div with sequence of ids like d1 d2 d3 ... and I need to listen to their click event so I'm using a loop to add an event handler to them, Here it's my code:
for(var i = 0; i < $ds.length; i++){ var $d = $ds[i]; var xFunc = function(e){ document.title = "d: "+$d;
[Code]....
But when I click on each of them always the title goes to "d: 4" where 4 is the last value in $ds.
I'm creating a drop down menu so that when a user clicks on the drop down arrow and then hovers over one of the options, a bubble comes up and does a validation. The thing is that everything works fine in Firefox, but not in IE or Chrome. The problem is that the .mouseover() function doesn't work on the <option> tags in IE and Chrome, but it works fine in Firefox because apparently FF is the only browser that supports it.
I'm trying to make a page where you can change a page's layout through 2 separate CSS's via a button. i want to button to change text when it toggles the layouts as well. i have no clue how to do this with an entire CSS file, but here is something i made to change the background. could i use this logic to change the CSS of a page?
My plan is to create a JavaScript class, with some functions and variables, and one of the functions is called when a user clicks on a certain element. However, I need to find out the ID of the element that was clicked (in the example, that of the <p>) for further processing. It looks basically like the following:
[Code]...
The result was very crazy, because console.log(this) gave me the node as result, and console.log($(this)) did the same only as jQuery node, but trying to find out the attribute via jQuery gave undefined as result. I haven't checked if this.id would work (should probably), but I'd prefer to keep the whole script in jQuery, if possible. I suspect it may be an overusage of the 'this' keyword, but if so, what's the proper way to do it?
i'm looking for the best way to use global properties that defined at class level insid event handler functions.
for example : function MyClass() { this.v1 = "hello"; this.v2 = {name: 'joe', age:'30'}; this.link1 = $("<a/>", {id: "link1"});
[Code].....
actually, in link1Handler 'this' returns to link1 not to main class. so how to get class properties or functions inside the private functions of the same class?
I haven't come across an exampe that would enable me to pass data to my event handler.For example, if I click a button I want it to pass the value of an adjacent text input to my handler.
I've a very simple code where i am setting the font-size to currect font-size + 2 for a paragraph. Its set first time but when next time event handler is called it gets the same old value.code is ...

Can I change firefox/IE's min/max/X button lay out to lower right corner? I have a web app (let us say i have 2 pages input.php and output.php) when user enters data into input.php and click search output.php renders from server. But the user from anywhere on web should be able to close output.php by using lower right X button. (by default FF/IE has top right X button, may top left in case of MAC), in otherwords I need to change the output.php page NOT on a user machine but on server, so that each user get same lay out when access the page.
Since the client user has no totally installed flash player in their computer, so that No need to detect if they have installed flash player. I try to create an alert and I found out that it�s impossible to put a link in the alert. Now I remove the flash installer in my computer, so that the flash in my webpage become a box. I want to happen when they open my webpage that contains a flash; an alert or message on the top was appearing saying that �You do not have flash installed in your computer. Follow this link to get the installer. I try it using alert but the link is impossible to appear.
I have a <div> containing 3 buttons. The buttons have id's like this: Button 1: btnFoo Button 2: btnBar Button 3: btnBaz
I'd like to add an click event to each button to call a function named [button ID]_click(): i.e. btnFoo_click() btnBar_click() btnBaz_click()
So far I have this: $("#divButtons button").each(function() {. $( this ).bind("click",function(){ eval(($(this)[0].id) + '_click()'); }); }); This works but is there a way without having to use eval and still utilizing the lovely .each function?
I need to know how to add an event to a button. The specific issue is that I want to add an event which is a prototype function of a class. Consider the following as an example:
