function test() {
var DIV = document.createElement('DIV');
}
If I never insert DIV to any node its parentNode is null and being a local variuable it's reference is lost.Is it destroyed?or do I have to add it to a node then use removeChild?
I'm looking for a way to define a function that's only effective inside
specified function.
Featurewise, here's what I want to do:
bar_plugin_func = function() { ...; setTimeout(...); ... };
wrap_func(bar_plugin_func);
bar_plugin_func(); // calls custom "setTimeout"
So while plugin developer thinks s/he's calling top-level function,
I want to hook it by somehow injecting local variable with the same
name.
Simply doing something like
;(function() { setTimeout = function() { ...my custom implementation
})();
is not ideal, as that'll taint global scope. Actually, I can live with
that for now,
but it's my technical interest to find a way to define it locally.
i'm having the following problem, normaly i work with html css and php but for this to work i need to make a litle javascript function and i'm still kinda new to it. so here is my problem.i'm making a search field where someone has to select some radiobuttons.first it has a selection out of 4 items and then a selection out of like 20 but how do i get the value from the first function in the second?in this case i would like to have the following in function showStreek:

how to get a js variable later in the html......My page is here: [URL]I want to access the 'selected' variable from the function in <head> later in the page, to complete a form:
<script language="JavaScript">
document.write('<INPUT TYPE="hidden" name="selected" value="'+selected+'">');
</script>
I want to modify a local variable of the ready function set like so:
$(function () {
var modifyme = 0;
...
});
I cant change the code setting the ready function, as I am writing only a greasemonkey userscript. I already tried using the .data("events") method, but it never listed the "ready" event. Any function so I can modify the variable!
How to: pass local variable from <head> JS function to <body> textarea
I have a JS function in the head that calculates a variable. the function is triggered by the vevent of a button click. when calculation is done, how is it sent back to the page and placed in a textarea or textbox?
just a very basic question. Have a div (id - photos) with multiple images. 1) Does this select them all? $('#photos img') 2)If so, how can i capture this information? Like so -> var bunchOfStuff = ($('#photos img')); and 3) if so, why can't i do something like alert(bunchOfStuff.length)into code tags...
View 3 Replies View RelatedI have been staring at this problem for too long and most likely missing a simple solution so I hope somebody can take my blindfold off and show me the way The markup (which comes from a CMS and I cannot change it) I am working with is akin to:
<div id="faq">
<p><strong class="open">FAQ 1</strong></p>
<p>FAQ 1 content lorem ipsem lorem ipsem ad infinitum</p>
[code]....
Notice how the second fo 3 FAQ sections has 2 paragraphs under the 'trigger' rather than 1? Therein lies my problem, because what I am doing with prototype.js is:
1.) Loop through page and collect all <p>'s
2.) do a .each iteration and attach an onclick event on $$('p strong.open') - assume this node for each iteration is now var 'trigger'
3.) run Element.hide() on trigger.next()
4.) in the onclick event, run Element.show() for trigger.next()
- If you are still following so far - my problem is that next() only shows/hides one single element and that is the <p> holding the content - which is fine except when there are 2 or even more <p>'s with content I need to act on. I;ve experimented with nextSiblings and adjacent() and I end up with too many nodes - basically every <p> in the entire document. I just want 'hide all P's after the trigger P up until the next p > strong.open
I am probably going about this all wrong, but I'm not sure how to do this.Basically I need to create a unique variable name for each element that has the same class name and set each one to zero.I thought I could just concatenate the index value to a variable name to create unique names. Something like:
$('.toggle-trigger').each(function(){
var toggleTriggerIndex = $('.toggle-trigger').index(this);
var t + toggleTriggerIndex = 0;
[code]....
So let's say I have a list of 11 elements and I want to wrap groups of them by 2.
[Code]...
Demonstration code:
The 'array' variable contains strings representing the id's of different elements. If the for loop above were to finish iterating, would all the links in all three elements call the click function (that displays an alert message), or would only the last element ("element3") have the click function? For me, the latter seems to be the case unless if I'm doing something wrong, but I would like clarifications and, if possible, alternative solutions as to how I can achieve the former result.
Is there a way to get the visitors *local* IP-address in javascript? I mean his LAN address like 192.168.1.x, not his regular IP-address.
I found several approaches that attempt to do this, but they either give me the external (regular) IP address, or they give 127.0.0.1 which doesn't really tell me anything. I need the local network address.

View 2 Replies View RelatedIn jslint's doc it says, "JSLint does not expect that a var will be defined in a block. This is because JavaScript blocks do not have block scope. This can have unexpected consequences. Define all variables at the top of the function." What are some of those unexpected consequences?

as a Local Area Network (LAN). A wireless network does not require
hubs, switchers, or routers to include additional users on the

A wireless LAN (or Wi-Fi network) may be configured in two different
ways:
Ad Hoc mode: Allows only for communication between different personal
computers and wireless devices, often referred to as peer-to-peer
communication.
Infrastructure mode: Required for communication with the World Wide

wireless connection requires a wireless network adaptor, often called

View 1 Replies View RelatedI am developing a web application where each page shows a series of small jpg images each with an onClick event which plays a small mp3 file using javascript.
It all works perfectly but is a bit slow to load, so the customer wondered if we might develop a local version which, although the page was accessed via the web, the images and mp3s were installed on a users local pc (will be machine specific application anyway).
I have managed to do this for the images by using:
<img src="file:///C|/folder/home.jpg" onClick="EvalSound('shortname')">
and adding the site as a trusted site in IE7 (after much head scratching!).
However, my embed statement to embed the local mp3 files doesn't seem to work. I am using:
<embed src="file:///C|/folder/filename.mp3" autostart=false width=0 height=0 name="shortname" enablejavascript="true">
I have tried all sorts of versions of this path and nothing seems to work. I just get an 'unspecified error' when I click the image.
My current set up is a form that gets someone to enter "City, State" then when they hit the submit button i used PHP to set up a variable called $location which was set to google.com/maps?q=from%3A+city,+state+to%3A+city,+state the $to variable is sent from a hidden input and is equal to the club they want to go to. After that i do a few string changes to get rid of the spaces. after its' all done it becomes $location.
What i currently have is a simple window.open() using javascript to open up the window. This works fine with one major problem.. popup blockers stop it from opening and the people browsing this site aren't exactly tech savy. They usually have no idea how to allow popups and this becomes a problem. The only reason i have it set up the way i do now is because my javascript is very limited.. but my php is pretty good. Is there a better way to open up the new window without popup blockers stopping it? If not do you know a way I could set up javascript to change a hidden input on the fly as the person enters their info so i can just use method="GET" and have the action to google.com/maps.
I have built something that allows me to choose a filename, filetype and the content of the file then save with the filename and type to the same directory.

View 8 Replies View RelatedI've spent 30 minutes or so googling to find the answer to this question, and I haven't found it. I'd like to use JavaScript to get the contents of a URL on the same domain (locally). For that matter it will be within the same directory on the domain.I was hoping there'd be a simple "getURL" function that would assign the contents of a URL request to a variable. One that isn't terribly platform specific, either. Is there such a thing?I'm creating a script that will perform 3 different searches at my website, and place the results in 3 columns for easy comparison. It's somewhat of a metasearch, extracting similar items from 3 different websites. The local CGI script on my website (the one I'm hoping to call using Javascript) makes the query to the external websites. The problem is that it can take sometimes 5 to 10 seconds to finish all of this, where one site in particular can be fairly slow.
So rather than make the visitor wait 5 to 10 seconds to see anything at all, I thought a good solution would be to have the CGI script display a page quickly, showing that site #1 is being searched (and displaying results once it's finished), then site #2, then site #3. Ideally the results from site #1 would have JS that would trigger the search for site #2, and so on.I've done this before using frames, but I was hoping to avoid having to use frames.I'm not a JS expert, but I know how to use createTextNode to insert the contents of variable within the document.The only thing I need to know how to do is assign the contents of a URL request to a variable.

I am trying to make my site so that when my boss needs to view the website when there is no internet he is still able to go from page to page. I set it up in dreamweaver and just put not ftp information in it, does that mean he can view it without internet now. Also I can see my navigation which is a javascript navigation, when i view it in the browers.

I am a back en developer and really don't understand event driven/front end development so if I use newbie terms or make no sense please bare with me. Could someone point me to some tutorials on how I might render something if and only the local machine has good processing power/ram. I am going to be rendering some stuff which will require quite a lot of processing power on the local side. Just a threshold thing really nothing predictive or anything just if ram is more than 1GB and processor faster than a P4 or something like that.
