The goal is to change the source on the fly (as with a firefox extension webdev or another or even Greasemonkey) to add a link. Until then, easy does it work well. This link launches an application ajax jquery like:
$.get(...) or even $.ajax(...)
If I'm on [URL], added my link, I click and it works, I see the ajax request and pass my "alert ()" gives me the return of application. Great! But if I'm on a site other than mine (the url of the ajax request is [URL] while I'm at [URL] for example), the return of the ajax request is empty.
How can I force .serialize() function not to read the empty fields? I only want it to serialize those fields with data inside of them.

Every time I get a user to fully validate all information I keep getting an empty alert box. Why is it showing up empty and not with a total amount? Im 95% sure my code is correct.
Code:
<html>
<head>
<script language="javascript" type="text/javascript">

I am building a registration page . If the user completes all the required field i load the info into the database but if there are missing fields I combined some javascript into php to display next to the empty field a note that it should be filled. This is my code...
View 3 Replies View RelatedI'm trying, to fill a table with data I receive from a Servlet. In Chrome everything works fine. But when I try the app on IE the responseText is allways empty. The following is my JS code (using prototype):
function updateToDeleteTable(){
var url = 'getDefHidConFechaInsercionMayor?plantacion_id='+$('plantacion_id').
options[$('plantacion_id').selectedIndex].value +
"&fechaDesde="+$("dateSelect").options[$("dateSelect").selectedIndex].value;
[Code].....
I know the servlet returns a correct text, because when I enter the request uri in a new IE tab it returns the appropiate html code.
Allso when I check the variable response in the IE JS debugger the resaponse of the servlet is 200 (OK). I realy can't think of anything I'm doing wrong, exept, that maybe there is a size limit for the responseText.

View 1 Replies View RelatedI can add rows to a table dynamically. Usually triggered by a mouse click but something I am trouble with is how to get the table to a state with no rows or columns just like it has no contents. do believe I can use this codedocument.getElementById('results').tBodies[0];but I am kind of clueless where to find a complete DOM reference or a manual and don't know the attributes or properties I must use to empty (if it is even possible) a previously created table.
View 5 Replies View RelatedI need a simple script that will check onclick if the user has entered something into the input text form. If they haven't then just alert that you must enter something to search for a term. I had something like this before, but the problem I was having was that it was alerting but right after you click okay it would continue on to the next page... Which kinda make the whole alert thing pointless... Also, I'm about sick in tired of not knowing JavaScript, where is some great sites to get my learn on?

I need to iterate through a group of arrays and search for a user-chosen word every time.
The problem is i can't declare how many array elements will be needed, such as: new array = (12), because some words inside my arrays, occur more than others.
So i need to decalare an empty array with x number of possible values.

I'm using a Javascript gallery (runs on Prototype library) that populates a caption field if the user has entered a caption for an image.
I need a little bit of code to hide the caption's div entirely if the user hasn't entered a caption for a particular image (var 'caption' is empty).
It's the bottom-right white box below the image, you'll have to click over to the second page of the gallery (NEXT) to see an example of an empty one that I want to hide:
[url]
Here's the CSS:
Here's the HTML:
I'm sure this isn't that hard, but I've spent more time trying to get that caption box to hide than setting up the gallery.
I need to check if a span is empty but every attempt at doing this has failed. This is in a for loop so it has to be able to change the span its checking.
var ids=new Array('PSN','XBL','xfire','steam','tweet','fbook');
for(i=0;i<=ids.length-1;i++)
{
if (document.getElementById(ids[i]).innerHTML == '')
[Code]....
Never runs... I have tried a few other things I've found on the internet but they don't see to work either.
I've debugged this and found out the code stops running on this line.
if (document.getElementById(ids[i]).innerHTML == '')

I'm making a page which gets the contents of an xml file and creates a table and populates it. The problem is when it loops around it seems to strip everything from the page HTML, HEAD, BODY tags and everything inside of those and just puts the value of the elements from the xml file onto the page. My question is, am I able to perform this loop and keep the rest of the contents of the page intact? I've been trying for most of the day and I can't get this working.

I simplified the code so each description is in an array. however, sometimes the arrays will not have any description, and i need those ones not to show up. How would I stop the blank arrays from showing up? for instance if tickercontents[3] is null,i don't want it to display? Code:

I'm developing a wordpress based site using custom fields. It is basically a database of company sites we serve hosted locally on our systems for our reference only.
The fields are manually inserted into the single.php file which outputs the variables typed into the text box in the "add new post" page.
For example <?php the_field('domain'); ?> outputs the domain such as ds02.jamies.local in plain text.
Here is a small excerpt of the page:
Code:
The div "post3" is basically a big box with a border and background. Inside that is the title for the box, then the php variable enclosed in a div "inside" underneath.
Now in most cases, we do not have all the information. There is around 40 boxes and if only 10 are filled in, its quite a headache scrolling past 30 empty boxes trying to find filled in one.
Is there a way, using simple javascript to simply hide those empty boxes?
