I wrote a simple script to remove an element of an array but I don't think this is the best way to go about it. I have a list of about five elements seperated by ";"
I split the array using array.split(";") command and proceeded to update the elemment by assigning the null value to the arrayindex
array[index]=""
This of course assigns null to the element
But there are two problems
1. The array size is still five instead of 4 and my list is now seperated by "," with an exta "," to go.
I am trying to code a quicklist for my site I am have a little trouble I can add a element in a array but when removing it is not working I have posted the code below
Code: <script type="text/javascript"> var propList; var curPos; var curSize;
I'm working on a Wordpress site and am using a photo gallery plugin. However, this plugin, for some reason, generates an empty table row and it's messing with my layout because I'm inserting a background image for each of the "TDs". I don't want to mess w/ the core files since the changes will be gone after the next upgrade. check out these two image links to see exactly what I mean.

I know there are ways to dynamically remove elements using DOM. Would I be able to use that method here?
-edit- This gallery is paginated and I just noticed that on the last page, the last row actually contains two pictures and a " ". So, a better question would be: Is there a way to target just the td elements that have in them so I can add a display:none via css?
I have a number of DIVs that I want to make 'selectable' on click, which means that I give the DIV you click on a class (just to show it's selected) and save its ID into an array. When I click on that DIV again, the class should be removed and its ID should be removed from the array as well. My code goes like
var selected_items = new Array(); $(".selectableDivs").click(function() { if($(this).hasClass("selected")) {
[code]....
But the alert at the end of the code always shows my a list of all divs I ever selected, even those that I unselected again. The IDs are just not removed from the array. Is that maybe because items saved in the array are not exactly $(this).attr("id") anymore?
Using javascript how do I remove all the data within a particular table row and store it in an array. Then if the user wants it back I append the information to the same table again from the array.
I'm trying to remove an html element in the example below. I don't see the "bye" message at the end and there are no errors reported in Firefox or exceptions caught if I wrap the remove child line in a try-catch. Any ideas what is wrong?
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"> <html lang="en"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <title>garbage</title> </head> <body>
<div id="my_div">hi<div>
<script type='text/javascript'> var my_div = document.getElementById("my_div"); my_div.parentNode.removeChild(my_div); document.write("bye"); </script>
I have a question about removing an item from an array.I am looking to remove an item from the array based on the property.Ie.arr = [{a1: 1, a2: 2},{a1: 3, a2: 4}, {a1: 5, a2: 6}]remove first item from array because a1 = 1.I am not entirely sure how to do this. I tried messing around withgrep a bit, but that didn't turn out well.
I'm using the following code that adds to <a> tags to each <td> inside a table. $(document).ready(function() { $('.calendar td:not(.notinmonth.)').each(function() { $(this).append('<a href="#" class="available am">AM: Available</a>').append('<a href="#" class="available pm">PM: Available</a>'); }); $('.calendar td:not(.notinmonth.)').each(function() { $(this).has('.event').remove('.am'); }); });
The second half of the code looks to see if any of the cells contain an element with class 'event'. If one exists, then the '.am' anchor should be removed. However this does not appear to be happening. After carrying out a few tests with the 'alert' function, it looks as though the script thinks that every cell contains a '.event' element, but I have no idea why! Not only that, it doesn't remove the '.am' link from any of them.
Here is the markup for the table (the cell with 'Day 9' in it is the only one that should match having an '.event' element: <table class="calendar"><thead> <tr><th>Mon</th><th>Tue</th><th>Wed</th><th>Thu</th><th>Fri</th> <th class="weekend">Sat</th><th class="weekend">Sun</th></tr> </thead><tbody> <tr><td class="notinmonth"></td><td class="notinmonth"> .....
I have table that has four columns and many many rows. It is quite long. I need to add a special divider (border) between each td cell. I thought I could create a css style .border_right and apply it to all td cells using jquery addClass() and then remove the class from the fourth td cell in each row so it does not add to or affect the outside border of the table.
My question is, how do I remove the class from the fourth td of each row using jQuery? I figure there has to be a shortcut way (one or two lines) to do this using jQuery so I don't have to manually add a 'class="border-right"' to each td I need it on.
I have a contact / upload form, but my validation file size is too big as much of the elements are not in use, i am not to smart in jquery / scripts so please tell how to remove unnecessaryelement in this javascript, like date validation, check element, drop down, elements....
I have a JavaScript file which Adds and Removes elements when you click a button.
Adding stuff is okay, but removing elements is more complicated.
When you add an element you also add id=x. Each time you add an element x goes up one. For example if I click "add element" 5 times it would be like this:
HTML Code:
If I wanted to remove the thrid element then I would want the following divs to replace it, for example it should look like this:
HTML Code:
I can't figure out how to do this, here is what I tried but it won't work
if i use jquery to attach a click or keyup handler to an element, and then later remove that element form the DOM, do i need to clean up/remove the handler first?
how would I go about removing one of the inner objects - s1 or s2? I've tried all sorts of ways but can't seem to get anything to remove an item from a jQuery object.
I'm trying to grab values from a set of arrays based on the value returned by my select box.
**Caveat - this is not an area I have any real experience with**
My arrays look like:
Code JavaScript:
I then need to test for each, then associate with one of my fees arrays, then grab each of the values in the array and write those values to elements within my page.
I'm then doing this to evaluate for each degree
Code JavaScript:
I need to first figure out how best to import all of these 60+ arrays and then in each of my conditions pull out each value and write to my page.
There is a unique 1 to 1 relationship between each degree and array so I can't consolidate as the values for each degree differ slightly.
I've a graphic designer who wants to be able to see what he's styled and what he so far hasn't. So I'd like to write a script that will work in, say, FireFox, so that he can point FireFox at has websites and the script will loop through the page after its loaded and perhaps for each element do something like throw an alert() with the style rules. I can call the style() method on each element to get its rules, but how do I get every element?
Im trying to add to each element within an array. In this program I have an existing array which is called aScores. I have copied its contents into another array called aScores using slice. Now Im trying to add the value of variable called classCurve to each element of aCurve using a for loop (see under the Curve Scores functrion section). However, it does not seem to add the two together(e.g 78 + 5).
I'm fairly new to javascript. I have a code where I'm trying to generate scrollx1 through scrollx100. I can get the array to work with doc.write and I can get one concat variable to work in the element but when I combine them it doesn't work. Any suggestions as to what I need to add to this code:
var sp=1; for (sp=1;sp<=100;sp++) { var sx = "scrollx"; var sy = "scrolly";
function overlay(e,num) { var targ; if (!e) var e = window.event; if (e.target) targ = e.target; else if (e.srcElement) targ = e.srcElement; if (targ.nodeType == 3) // defeat Safari bug targ = targ.parentNode; targ.src = fdot[num].src;}
Overlay is called as an onmouseover event from an image's map AREA tag, sending event and a number. FF's JS Console spits out that fdot has no properties. Ideas? Better ways to do this effect (replace the image depending on which area of the imagemap is mousover'd)?
when I capture the dispatch of the form and try to get the value of any of these file fields:
PHP Code:
There's a Javascript error saying that form.file is undefined. It's strange because I see in Firebug that "file" actually exists as a property of "form". The same happens if I get rid of the temporary variable "form" and I do it this way:
So, I eventually had to use the getElementById('image' + i) method in order to do what I wanted. But there must be a "natural" way to get a value from an array defined in a form.
