Say I have the following code:
And I want this code to print 21.
How should I implement the function Curry?
I tried intuitively:
But it didn't work.
There is a frame, the top part of the frame contains a button. On clicking the button, the bottom part of the frame changes colors, which are contained in an array present in the head of the code.
For some reason, this is not working, perhaps something wrong with the way I have assigned the parameters. Code:
Ok so the following code works.
function myFunction(myName)
{
alert("You are "+myName);
}
callFunction = "myFunction";
parameter = "Joe";
[Code]...
I totally understand that in order to learn javascript I need to know how functions work, I understand the basics of passing in parameters and then calling the function with the values to maybe add something together etc I ve read countless articles about functions as well as books etc but I just dont get how they are used and when they should be used etc, the more advanced functions that have maybe 4 parameters and are doing different calculations and returning various values that get fired back into the script just totally confuses me.
What I would like to know is first of all how can I overcome this confusion and also any words of wisdom you may have. I will also add that I have no prior programming experience and have spent the last 2 months frequently hitting my head off a brick wall as I just cant understand javascript.
I am having a problem removing an element after adding it.
This removeElement funcrtion works in IE but not in FF code...
As you might know, removeNode() is an IE DOM extension (works only for IE5, IE6 and Opera 8 but not in IE 5.2 for Mac, Moz, Safari.
Following one of my clients request I think I found a cross-browser solution to remove a node but keeping it's childs. The request was to find a function which will remove, onevent, the <a href=""> tags, but keeping the inner text.
This is what I have done. If you know a better or a shorter solution, please let me know:
function removeN(tag){
var tags = document.getElementsByTagName(tag);
for (var i=tags.length-1;i>=0;i--){
var root = tags[i].parentNode;
var kids = tags[i].childNodes;
var eSpan = document.createElement('span')
for(var j=0;j<kids.length;j++){
clon = kids[j].cloneNode(true);
eSpan.appendChild(clon)
}
root.replaceChild(eSpan,tags[i])
}
}
the variable tag might be 'a', 'strong', 'em'....
I guess that the code might be used as a crossbrowser solution for replaceNode() as well. In fact the code as it is replaces the node tag with a <span> tag, but it might replace it whith another desired tag....
We have to develop a small engine which the client uses. It supposed
to work like this. Our engine resides in a frame (frameA) which will
be loaded only once and it provides set of functions. The client can
call these functions. We inturn should get the values from the server
or set the values in the server and return with the values. The way we
are planning to implement is that we will have have another frame
(frameB hidden) and submit it whenever the client (frameClient) calls
our function and wait till the page reloads and return with the value
( set in the reloaded page by the server). The problem we face now is
that we don't have any sleep functionality in javascript ( being event
driven) and if we have a loop waiting for the reply, it will consume
the cpu cycles and the the frameB wont load.
Posting this in javascript because the problem might be caused by my scripting.
I made a 3 page long form using javascript, and the contents of the second page aren't submitted to the php script. link (http://rolstoel.dlnet.org/toevoegen.php?page=1)

I'm making a php/html page and using javascript to keep a count for me. code... The last button is just a test button, which will tell me what the value of "i" is, but I'm not getting anything when I cllick that button.
However if I change the onClick from alert(i), to alert('i') it will alert me a string, so I know the javascript is working.
I am trying to fix some datetime strings so I can convert form values into date objects so I can compare the dates in my validation process. the date time strings look like - 7/21/2011 8:00am
for some reason the am is not being replaced by " am" . here's the function code...
Here's a little code snippet solution for Popup Killer software:
<script language="Javascript">
<!-- begin
function winopen(url){
var Win = window.open(url,"popup","menu=no")
if (Win == null)
window.parent.location.href='disablepopupkiller.htm'
}
// end-->
</script>
<a href="javascript:winopen('popuppage.htm');">click</a>
If the new window is "killed" because of the software, it loads a new page in the parent window ... or the last line of code can be replaced with a document.write('content here'); or show a hidden <div>. Any of these three can be used to tell the user to disable the software).
It works on my computer with ie6 ... let me know how it works on yours (if you have popup killer software installed).
I have been looking around for quite some time for a simple piece of code that allows rows to be collapsed in tables, so when you click on a link in the tbale the row beneath collapses. All i have found are very complex codes that i cant get to work or that dont work in both IE and FF.

So the idea of the code is to load an image from a record, and echo both scenarios of 1) the image being a valid size and fitting in the table, or 2) the image width is too large, so add on width='100%' to the image. After both rows have been loaded, call the javascript function in PHP to hide the appropriate table row.

I have some java script in my vb.net application and I've been trying to figure out why my web app keeps crashing when i try to instantiate an array (i placed a comment where the app is crashing in the code below). Here's my code..
Hopefully the code above is enough for to figure out the issue. However, here's a mini recap of what's going on. A user selected a value from firstListBox and the function above copies it over to secondListBox. The code in the first condition works fine, but the code in the else block doesn't. Now, here's the catch/difference between the if and else statement...the Else block is basically doing the same thing as the if statement, except the values that needs to be copied are coming from a session variable (hdnSessionVariable = '<%=Session("playerId")%>'. I've commented out every line in the else statement and the app works until it hits the secondListBox.options[secondListBox.options.length] = newOption line. Anybody have any idea what's wrong here?
Let's say you're getting some xml via ajax, instead of the ajax.responseText property you create a dom document using the responseXML property.
Is there a safe cross-browser way to query that document using xpath?
I know in IE you can use selectNodes/selectSingleNode, but what about other browsers?
I have a page where users can filter a list of links using javascript clicks. The user then clicks a link in that list, views the page and then clicks back on the browser to view the rest of the list but the javascript options they filtered in the list are gone resulting in them having to do it all over again. Is there a solution to this?
Would it work if I store their selections in a cookie each time they click a javascript button and then when they visit a link and click back (to what is presumably now a cached page) will I be able to have javascript that will read the cookie and reset their options again or is the cookie not loaded on a cached page?
Are there any common solutions to this kind of thing?
I am trying to use the slideshow javascript found at this site
but i can't get the following line of code to stick in my webpage code...
i follow the directions exactly, but that line above keeps getting 'spit' out of my page altogether...in fact, my webpage does not have any body tags per se, it keeps spitting them out when i try to put them in. the webpage functions just fine--no problems--but i can't get this slideshow script to work b/c i can't get the 'onload' instruction to stay--that body tag keeps getting stripped from my html page...
any ideas as to how to make this script work for me?

View 4 Replies View RelatedI am wondering what is the way around when the javascript is disabled?
For example, I am creating menu with bunch of drop down lists. The lists are dependant on the others. So, when I change the selection on the previous list, the elements on the next list should change. Of course this won't happen when the javascript is turned off.
I want to focus on my error field but this won't work in firefox code...
