Strings Not Replacing Strings
Sep 25, 2007I've been learning javascript for about a week and I'm really struggling right now. This is a homework assignment to help in learning loops and arrays.
What I want to happen is when a form button is hit it will replace the array from the one previous instead of just adding to it. Hopefully that makes sense. What do I need to do? here's my code....

JQuery :: Converting Onmouseover / Onmouseout
Apr 21, 2010I'm working on a couple of pages that look like this: [URL] As the visitor mouses over the month name, the image to the right is supposed to change to show the cover of that month's magazine issue. The onmouseover/onmouseout code has been working fine for months, but I recently added a couple new JS elements to the page, and now when the visit stops hovering over Sep/Oct, the image doesn't change.
I'm thinking that the way to fix this is by converting this action to jQuery, which is loaded on the page anyway, but I'm struggling to get a concise expression of what I want to happen. That is, I can do it by brute force with dozens of lines of code, but there must be a better way.

JQuery :: Converting Span Into Textfield On Mouse Hover
Sep 13, 2010I created an html page and wrote javascript which uses jquery's hover() method. It converts a textfield into a span when mouse leaves the textfield and converts the span back to textfield when mouse enters the span. Also,I created a button, which when clicked executes a function that takes the val() of element with id='title' and shows it in an alert. I encountered two problems:
1. This works fine as long as the text field contains default text. But if I leave the textfield blank by default, the hover method can't detect the span and will not convert it to textfield. Is there some way I can create the textfield blank and yet make hover() work?
2. After I place mouse over the span and enters some value in the textfield, I move the mouse cursor onto the button and clicks it. At this moment, the span has a an id='title' and so $("#title").val() should get the entered text.
However ,the alert shows empty string of length=0. I tried this ,without moving the mouse cursor out of textfield and clicked the button using TAB-Enter.This time the alert shows the correct entered text. Why is this happening? Shouldn't the $("#title") be able to get the span element with id=title and .val() retrieve its text?
The html is
<html xmlns="[URL]"
xml:lang="en" lang="en">
<head>
...
<script type="text/javascript" src="../includes/jquery-1.4.2.js" </script>
<script type="text/javascript" src= "../includes/sample.js" </script> .....

JQuery :: Hiding Single Strings On A Page?
Apr 20, 2010Is there a simple way to just hide some text in a page? Browsing the documentation I found the .hide() function. But how can I tell jQuery to hide all occurrences of a specific string? If I use the :contains() Selector I can find the text but can only hide the element that contains the text not just the text.
View 2 Replies View RelatedJQuery :: Add A Function To Appended Html Strings?
Oct 7, 2011I want to create a questions creation page. It has a Question Text Box and a Add Button.When users press the add button, there will be a newQuestion Text Box and a new Add Button appear in the next line. But the old Add Button will become a Delete Button and change its functionality.[code]I put all the Add Buttons and Minus Buttons into two different classes, ".buttonPlus" and ".buttonMinus".The .buttonPlus works well when the line is added by the main html. But it fails to work when it is added by the .append() function. It simply adds the .buttonPlus's CSS code to its button, but the$(".buttonPlus").click(function (event) {...} is NOT attached to the new buttonPlus.

Is there a way to parse that string only once, maybe create some sort of "compiled" version of the check, cache it, then give it to is ? Or does jQuery cache the string after parsing it once so I don't have to do anything?

JQuery :: Converting Standard Show/hide Code To Plain JS?

$('.tab_content_wrapper').hide();[code]....
'this' evidently does not refer to the element that was clicked on...also, can you refer to elements by their class name? also, is it possible to do event-binding in plain JavaScript w/o using individual id's for the clicked-on elements?

JQuery :: 1.4 Slower Than 1.3x When Using Append Or Html With Large Strings?
Jan 18, 2010I've been using jquery for some time, and was very excited about the improvements in jquery 1.4 I have found however, that in one particular instance, jquery 1.4 seems to be performing slower than 1.3x, to the point that it has forced me to downgrade the script. I use jquery heavily throughout my web application; in this particular case, when a very large block of html consisting of a bunch of <tr>s is .appended (or .htmled, tried both) to a table, jquery 1.4 in firefox will give the "unresponsive script" error, prompting the user to stop, debug, or continue. The same block of html works perfectly fine in jquery 1.32 (and quite fast too). I haven't had time to do too much experimentation, as this is in a production environment, and thus downgrading was necessary as it was breaking the page, but I would love to figure out why this is happening so that I may optimize the code sometime in the near future. Have the improvements to .html resulted in code that causes higher cpu usage, or that would have a much higher overhead on longer strings? I've commented much of the code around the call, so that it pretty much consists of an ajax call that returns a chunk of html, which is inserted to a table (that I first empty). I thought it might be something with event bindings that occur after the insertion, but removal of these event bindings does not resolve the unresponsive script error. It seems the .html or .append is doing it. Note that this code, as is, works perfectly in jquery 1.3, even with event bindings, etc.
Does anyone have any ideas? My next step was going to be to try returning the entire table including the <table> tags, and doing a replace instead of an append, but if anyone has other suggestions to try, please let me know. Also, just as an aside, what do you guys consider the 'best practice' to be when returning dynamic data for a table (server side sorting, filtering etc from a db) ? Do you return just the data in json, and repeatedly clone a row element, replacing the values in each row (thus decreasing the size of the ajax call, but increasing the client side processing), or return the full html, and replace the innerHTML of the table?
JQuery :: Stop Tabs With Query Strings From Reloading Page?
Aug 18, 2009I have a set of tabs that are set with an href that adds a query string to the url such as "?t=1", meaning the first tab is selected.

I'm using a jquery plugin to handle the query strings. [URL]
Here's the piece of the code that matters:
var url = location.search;
var tab = $.query.get('t');
init(tab);

JQuery :: Dynamically Declaring Functions - 'array' Variable Contains Strings Representing The Id's Of Different Elements
Oct 12, 2010Demonstration code:
The 'array' variable contains strings representing the id's of different elements. If the for loop above were to finish iterating, would all the links in all three elements call the click function (that displays an alert message), or would only the last element ("element3") have the click function? For me, the latter seems to be the case unless if I'm doing something wrong, but I would like clarifications and, if possible, alternative solutions as to how I can achieve the former result.
Converting ASP To JS?
Sep 9, 2009Not sure if this should be in the ASP forum or this one (probably could go either), so here goes. I don't know hardly any - probably best to say dont know any at all - javascript. However I have a need to convert some code from asp to js.
the code is checking to see if certain variables are null and if so counting how many of those variables are as such.
the ASP looks like this:
<%
Dim counter
counter = 0
[Code]....
I need to know how to convert this to js so I can show this number to the user without sending data to the server first. I have searched the net for something similar but I am not having much luck finding any examples that do what I would like it to do (maybe this is not something that can/should be done in js?).
