This piece of code is throwing an error on I.E. 7, its because the drop down box is empty, can anybody advise me how to deal with it?
Code:
var category = sel.options[sel.selectedIndex].value;
if(category.length>0){

I am trying to test a form whether the fields are empty or not. If so, displays warning, doesn't proceed. Here is my javascript , and the forms.
/* Validate Forms */
function validate(){
var notify = document.getElementById('notification1');
if ( null == document.getElementById('usrname').value ||
[Code]....
The problem is it works only for the passwd, but not for the usrname, meaning when the username is empty it shows the message as i wanted but right after showing the notification, it is going to the action page. Since it is returning false, it is not supposed to proceed. For passwd, it is fine, it shows the warning and stops without proceeding action.jsp.
I am asking jQuery to tell me which drop down option is selected in a drop down list - like this:
I would like to check if this was successful before I proceed. What are the possible return values for this statement?
If no id exists.
If no option is selected.
If some other problem occurred.
In these cases am I expecting a null return; an undefined return, a false return value?
And, based upon the complete set of return possibilities, what would be the best and most comprehensive tests I could apply to cover every base.
The .find() method does not seem to match on input fields by using a class. The ti This problem seems to be only visible on input fields. The following is a demonstration of the issue:

I'm using the standard module pattern and the problem is once you set a private variable, trying to test that object independently becomes a nightmare as the next test is polluted by the actions of the previous.So, the options are to have some reset method (which is horrible), setters on everything (defeats the point) or delete object and re-load script (hideous).

this code is supposed to display and load a secondary drop down menu if a particular ID(13 OR 14) is selected from the first dropdown. it works fine for 14, but not for 13. the "test" alert displays for both 13 and 14, but the second drop down only appears when selecting ID 14. I changed my array to ('13','14','13') and then it worked for both 13 and 14. is there something i am not aware of?

I have the following code that test the target element of a mouse
movement to check if its and Image and the Parent is a Div element. It
works perfect in Fire Fox, however IE does not allow access to test the
target against instance of HTMLImageElement or the Div Element.
Is there a property that I can use to get the object type that will
return "image" or "div" or anthing else that I can use. The typeof
function only returns "object" which is totally useless in my
application.
DragObject.prototype.mouseMove = function(ev){
ev = ev || window.event;
var target = ev.target || ev.srcElement;
var dragObj = target.getAttribute('DragObj');
if ( target instanceof HTMLImageElement && target.parentNode
instanceof HTMLDivElement){
target = target.parentNode;
dragObj = target.getAttribute('DragObj');
}
}
I have Javascript on my site and will not work at all if JS is disabled.How do I notify my users that the pull down menus use javascript and will not work unless they turn it on?
View 2 Replies View RelatedI have a form on a page that the user fills out. When he's done and it's validated, I need the contents along with some other stuff to be printed before it's sent to the server. To accomplish this I'm using window.open on the Print button, then I intend to reference the fields from the page which opened it using the window.opener.formname.fieldname.value .
Problem is I have couple sets of radio buttons on the form that was filled out and I would like to print all the radio buttons showing the selected one so that the user acknowledges on the hard copy what his choices were.
If I was doing it server-side(ASP), I'd test the value of the incoming form value by executing a function, and I'd like to do it that way too, but I can't seem to figure out how to do that without putting <SCR IPT>function...</SCR IPT> tags with every radio button <INP UT> tag.
This also applies to where I'd like to write the values as HTML.
i'm having with a superfish menu i have tried to add to my wordpress site.The menu seems to work fine for the base-level (top parent pages) menu items.But the drop down menus seem to flash on screen for just a second and then disappear when the mouse hovers over the menu items.To see an example, please check out the top menu on this temporary development page: http:[url].....I have tried adjusting the z-index in superfish.css file but it doesn't seem to be having any effect.

How do you test a variable is an Array or not in Javascript?
Indeed, I need to get the html checkbox info in an html form like this:

When looping thru a group of elements and using getNamedItem('itemname').value there are some elements that are going to have a null value for that particular getNamedItem... the problem is that you cannot test this value to see if it's null because it generates an error instead, and the code does not continue: _allnames[_j].attributes.getNamedItem("onchange") is null
You cannot even test it for null like this: if (_allnames[_j].attributes.getNamedItem("onchange").value != null) { do something } This will also generate an Error instead of testing to see if it is null.
How do you test getNamedItem for null to avoid this error?
EDIT: It appears that the problem is limited to Firefox. It works fine in IE7, but the error occurs in both FF v3.5.4 and in v3.5.5!
In my example below, there are no elements that match, so you should see an alert box that says 'No match', but (using Firebug) you will see that an error is generated when it tries to find the value of onchange in the last input tag.

I am doing an image/data rotating script. I get the data from a XML. I parse that data and build the divs and such.Data Set 1 --- background image in a div, with a button and some text overlayed on the div.
...
...
Data Set 4 -- etc..The thing is, I load the script and the div appears, BUT the text overlay appears first THEN the image pops up for the first Data Set. I can't have that. I need them both to appear at once.Is there a way to determine that a div background image is loaded?-- I have access to the prototype js library.
Say I have two sets of radio buttons. One is group name "location" and the other is group name "time".
Lets say location has 4 possible values and time has 2 possible values.
All location values should be both time values as a possibility except the last location value which should only be able to select 1 of the 2 time values.
How can I popup an error message if location has a certain value and time has a certain value.
I really don't know the operators to use. Please give sample code with operators if you can.
I don't know if there is such a thing as a if then radio selection or not but I figured javascript could do it instead.
how I can run / test code on windows? I also want to download the library.
