JQuery :: Passing Variables As Selectors
Dec 30, 2010What I'm trying to do is quite simple but as a beginner I'm getting incredibly frustrated with it. Here's my first attempt. I plan to do something a bit more fancy with the images, but I could see straight away that this wasn't the solution. Mouseover was changing the image before it had faded out and looked horrible. So, I thought I might put all the images in the same place and hide them, making them visible and bringing them to the front on mouseover of the corresponding hotspot.

JQuery :: Caching Selectors Inside JS Object?
Sep 26, 2010I have a complex JS object. It manipulates the page DOM. Inside it I have many repetitive selections spread across functions. I would like to cache the selectors to enhance performance. How do other people do this? I can cache on the function level but not the object. When I try to cache on the object level I seemingly end up with stale selectors that while defined don't actually work.
My gut is that I can only cache on the function level?
what I have read does not deal with caching inside a JS object.
JQuery :: Using Selectors With Click And Find Another Element Inside?
Jul 1, 2011I'm trying to create a list of recipes which will on document ready all be hidden except the first one. And then when I click one of the dynamically added links (in a ul) in the sidebar I want the corresponding recipe to go from hidden to shown. I've managed to do everything really simply except I have no idea how to find the corresponding recipe when I click a link in the sidebar (the links link to the recipes with #recipe<number>)
$(".post").hide();
$(".post:first").show();
$("a[href*='#recipe']").click(function() {
$(".post").hide(600);
});
Somehow I need to access the id of the specific recipe, which I suppose should be possible since the clickfunction should store that somehow?
EDIT: I just realized that I could just use the href value as my id for the recipe (since its the same e.g. #recipe). However I'm having trouble using the variable that stores the href/id in the .show function.
$("a[href*='#recipe']").click(function() {
$(".post").hide(600);
var theHref = $(this).attr("href");[code]....

Declaring/Initializing Variables Inside Or Outside A Loop?
Apr 30, 2007I've always wonder if there is diference when declaring and
initializing a varible inside/outside a loop.
What's a better practice?
Declaring and initializing variables inside a loop routine, like this:
for(var i=0; i<list; i++)
{
var name = list[i];
}
or outside a loop routine, like this:
var i;
var name;
for (i=0; i<list; i++)
{
name = list[i];
}
or are both the same....
As a programmer, i always try to practice good programming. I always
thought that by declaring and initializing the variable inside the
loop, i was creating a new memory space every time instead of just 1
time...
What do you think?

JQuery :: Adding Selectors To $(this)?
Oct 12, 2009Writing a sortable list function. My <li> elements contain several items (headings, paragraphs etc) and I want to add a class to the headings when they've been sorted. I have this code in my sortable init:
receive: function(event, ui) {
$(ui.item).addClass('editable');
},
This adds class="editable" to my newly-sorted <li> element - cool. What I want, though, is to add this class to the <h3> within my <li>. I tried:
receive: function(event, ui) {
$(ui.item + ' h3').addClass('editable');
},
but this just gave a syntax error.
JQuery :: 1.3 - Not All Selectors Work In IE 8?
Apr 23, 2009I found that certain selectors work in all browsers except IE 8 and they need to modified. This selector pattern seem to work well in all browsers, including IE 8: jQuery("input[class='class_name'][type='text']") But this identical selector works in Firefox, Safari but not in IE 8: jQuery("input.class_name:text") In IE 8 it returns a "property not found" javascript runtime error. I don't know whether that the actual issue or if it is a side effect of some memory leak.

JQuery :: Square Brackets In Selectors?
Apr 9, 2011While trying to get a selector to work with ids that include square brackets, I searched the forum and found that I needed to escape the brackets with '\'. However, while this works with my fiddle: can't get the exact same selector to work within my page in either FF or Safari. I've triple-checked the id and it is correct; I know that jQuery is working on the page because changing the selector to$('.nameinput') gives the expected results. can't change the id because I'm working within an existing application; I know I could add a class to the input and use that as the selector instead. I'd prefer not to and would just like to figure out why this isn't working.

JQuery :: Selectors Only Matching First Element?
Jun 4, 2009I'm trying to do is simple "select all" checkbox script. The problem is, no matter what I seem to do, only first element is matched. $("input:checkbox").attr("checked", true); checks the first box only. Same with: $("input:checkbox").each(... I even tried copying this script directly from the jQuery documentation page: $("div").css("border","9px solid red"); It applies a red border to the first div on my page.. the example in the documentation applies it to all divs.

JQuery :: Multiple Selectors All Changing Each Other?
Jul 19, 2010I am working on a customised scoresheet for a Bible Quiz group. Basically, I want to click on a box and have a box come up with options for correct and incorrect. I just want it to affect the score for that one box. However, if you click another box, it changes all of the boxes.[URL]..Click the 10, 20, or 30 in the top left corner. It should update the points under the 4. Click on any of the boxes assigned to a person on the grey line. A box should come up with a Cor (Correct) or Incor link. Click on either option. Then click on another grey box and do the same thing. I don't want all of the points to change when one person's score changes. Does that make sense?

JQuery :: Use CSS Selectors That Are Not Defined In A Stylesheet?
Jun 8, 2010Is it common to use CSS selectors that are not defined in a stylesheet (or anywhere else) to identify HTML elements? When using jQuery in ASP.Net with controls that implement INamingContainer, all it's children's ID's are automatically generated based on the id of the child control and the id of the container control (such as the Panel control) so we couldn't simply use $("#myChildControl") for a child control with the id of 'myChildControl'. The resulting client id would be something like 'mypanel_mychildcontrol' and for autogenerated controls within grids/tables, the id's get even more complicated and should be 'guessed'. So, how does/would people identify these types of controls when there are no preset CSS selector's for them?
On the server side, we can use the ClientID to get the generated ID, but for some things, I just want to do this totally on the client side without messing with code-behind.
