Looping Different Information Simultaneously Using Arrays?
Nov 20, 2011
1. I have this list of 3 products/items that is created and displayed automatically through a for-loop. By changing the number in this loop, I can either add or subtract items of this list. More and more items are supposed to be added to list on a regular basis.
2. For each item, a number of customer-comments should be displayed and looped. I accomplish this using Arrays, where I can easily add new comments for each individual item to the loop.
3. Each item may have a different number of comments.
My goal is to have a system that effeciently allows me to add new comments at a minimum effort from my part.The comments loops fine, as long as I only choose to loop them for one item at the time. As soon as I try loop comments for two or more items at once, trouble ensue.
Below is my code:
Code:
<SCRIPT LANGUAGE="JavaScript"><!--
//SBC verdicts
verds_sbc = new Array(new Array("Great Game!","Good game!","I love this!"),new Array("AVGN","CurlysWorldof SOftware","ANGRY JOE"),new Array("www.cinemassacre.com","www.curlyswordsofsoftware.com","www.angryjoe.com"));
What I'm trying to do is display whatever is typed within an input field simultaneously inside of a <p> tag.
For Example:
If the name Mark is typed into the input field, i would want "Mark" displayed somewhere else on the page inside of a <p> tag and the letters are typed in the input field it displays each etter as its being typed.. is this possible?
I have a list of inputs <div id="divID"> <input title="foo" type="text"> <input title="bar" type="text"> </div>
Then I'm trying to use jQuery to cycle through each input and ascribe ".attr("value") to each respective <input>. So far I've been using something along these lines: var input = $('#divID input') input.each(function(i) { var title = input[i].attr("title"); input[i].attr("value", title); } If I remove the "[i]", it fills in every box with the title of the first <input>. If I leave it there, it fills in the first input, and then upon looping, says input[i].attr is not a function. So, if I type console.log(input[1]), firebug returns the correct <input> tag, but as soon as I add the .attr(); function, it blows up.
I'm a JS beginner and I find looping through arrays with for/in is very easy. Yet I find lots of code examples where array length is used instead of for/in and I'm thinking to myself, why do it this (somewhat) hard(er) way?
I have a HTML form containing two text box controls in it and a submit button. When a user enters information in those two textboxes and click on submit, the information is sent to a function in Javascript. In the javascript, the information from those textboxes is stored in a javascript variable. The problem is as follows:When I am inputting string text in the html text boxes and in the javascript when I am trying to print those values, it is giving me out an error saying NaN. However when i input integer values in the text boxes it is printing those numbers. Is there a conversion that I have to do for the string to be printed. I am new to Javascript and need your help. This is a basic code of Javascript. Below is the code that I have.
<html> <script type = "text/javascript"> function square(form)
I'm trying to get multiple scripts to run simultaneously. As of now, my hover drop-down menu is not working on the "Teams" page, but all other scripts work. I have 3 other scripts running on the Teams page, and was wondering how I could get the menu to work as well (seeing how it's pretty important). Code:
If I don't use style="display:none" inside the divs, I see them both initially and I can hide/show each one depending on which link I press. But the thing is that I need both divs to be hidden in the first place, and when I click on ONE, to show TWO, when I click on TWO to hide ONE and show TWO etc. Each time 1 div should be visible, depending on which link we press. The other must disappear.
I developed a website with php. Using cms, users can upload an image and a textual description of this image.Using jquery, images change automatically.Now, i want that textual description changes with the imageIn my generated html code i have:
So at the moment I'm working on an Ajax powered navigation that's animated with a horizontal slide and fade. So far I've imported the Effects Core and Effect "Slide" from the jQuery UI to get the horizontal slide effect in. Here's the documentation on the specific slide technique I'm using from the jQuery UI:[URL].. You can see the work I've done so far:[URL]... As you can see, the Ajax and horizontal slide features are working properly. However, one thing I can't get to work is the horizontal and fade effect to occur at the same time. I mistakenly tried to chain the show/hide functions with the fade function, but of course it happened sequentially instead of simultaneously.
I looked up for solutions online and most point to the animation function as the solution. In this case, I can't figure out a way to work with it because the animation function seems to manipulate the CSS to get the desired effects. While I could have animate change the width of the content area along with its opacity, the width resize would squeeze the text as the content area shrinks which is undesirable for my case. This is why I'm using the Effect "Slide" in the first place, to prevent the text getting squeezed as the content area slides.
So is there anyway I can get a simultaneous fade working at the same time with the Effect "Slide", or do I have to look for other methods of horizontal sliding to get it to work with fades?
I am working on a project that shows archived data as well as current data on the same page. When the page builds, current data is shown, archived data is hidden (by using a div with id="archive"). I found comments here that getElementsByName was not a good cross browser way to handle this (and I'm not sure how to use that anyway). Can someone suggest the correct way to handle this?
There should be a link that, when clicked, will grab each element on the page with id="archive" and toggle the display property (none or block).
Here is the current code:
function archives(toggle) { if (typeof(toggle) != "undefined") { if (document.getElementById(toggle).style.display == 'none') { document.getElementById(toggle).style.display = 'block';
[Code].....
This works just fine, but only for the first element that it finds. I need many elements with the same name to be effected.
I'm one of the main developers from [URL](which is a gaming website), One of our main games is Free rider 2, Which we have converted to run via a database so people don't have to manually send around track codes so other people can evaluate their tracks. I am trying to build a track previewer in html5/javascript which will eventually replace our current one written in flash (which lags terribly on large tracks)
I am stuck on 1 thing though, With the larger tracks there are up to thousands of lines that are drawn using lineTo() moveTo() etc. And when i move using the arrow keys, It requires the javascript to reload the track, and parse every single line again, Causing the screen to turn white whilst it does so.
Is there a way i can use a similar method to the way it has been done in the flash version, where it is in a movieclip, which then instead of moving each line, it moves the movieclip instead.

I'm using Lightbox picture displayer [URL].. and a content slide show UI [URL].. on the same pagesimultaneously. Although when I connect to the javascript files in my html page one of the effects won't work. Whichever javascript file I include last doesn't seem to work.
In the scenario below my content slide show effects won't work because they are listed first. It seems that whatever is listed last overrides everything else. I've also listed the error I get when running the page.
Hopefully I 'm missing something silly, but I can't find an easy way to loop all list items in a simple <ol>. I was hoping a for loop as shown below would be enough, however clicking "alert all" in the following example gives me all but the first <li> element. The alertfirst() function finds the first <li> with no problem. There are multiple lists on the page, so getElementsByTagName('li') is probably not the most elegant solution. Btw. my Mozilla crashed when I tried this code, but this is for IE only.
<script type="text/javascript"> function alertfirst() { var ol=document.getElementsByTagName('ol')[0]; alert( ol.firstChild.firstChild.nodeValue ); } function alertall() { var ol=document.getElementsByTagName('ol')[0]; for( var i=ol.firstChild; i=i.nextSibling; i!==null) { alert( i.firstChild.nodeValue ); } } </script> <ol> <li>first</li> <li>second</li> <li>third</li> </ol> <a href="" onclick="alertfirst();return false">alert first</a> <a href="" onclick="alertall();return false">alert all</a>
i am fairly new to javascript and XML. i'm trying to loop through some nodes and drop the output into a series of DIVs using getElementById. here's the code for that: Code:
So, the aim of what I'm doing is to take any amount of text that's in a <textarea>, split it wherever there's a '=====\n' and then call each element of the newly created array back into the <textarea> in a sequential manner.[code]For some reason, my for loop doesn't work. It's only returning the last value in the array and disregarding the previous ones.
I need to loop through all form elements such as text, radios, check boxes and the like and to save their state in a file. does anyone have JS code to do this ?
I am looking for advice on what is "best practice" regarding looping through a form to check its checkboxes and associated data fields.
Here is what I am trying to do (Here is the page I am working on: http://www3.telus.net/thothworks/LinLeastSqPoly4.html). I provide a form for a user to enter up to twenty (M = 20) data pairs. The user need not enter data for all twenty pairs, but the user must indicate that data is present by checking the checkbox beside each valid pair.
If a checkbox is checked, two things happen:
i) a counter, numRows, is incremented to keep track of the total number of valid pairs entered.
ii) the associated two data values (being x and y) are checked to ensure that they are valid numbers and, if so, are entered in an array for use later.
Previously, my forms were small, and I was able to examine each checkbox of a form individually: "if (checkbox1.checked) do action A; if (checkbox2.checked) do action B; if (checkbox3.checked) do action C; etc."
However, now that my form has twenty checkboxes, and may get bigger, I would like to learn how to accomplish this task with a concise loop. Following is my first attempt and it seems to work. If anyone can suggest improvements for this code ....
If got problem with .each looping in jquery. im am trying to make a animation with jQuery. And i want to switch between three quotes of the array. and now it only works for the first quote of the array.
