Chop Up A String To Obtain Just The Filename Of An Image

Feb 9, 2006

I need to chop up a string to obtain just the filename of an image. Lets say the image source is /images/thumbs/image.jpg. Using the DOM I have the source of the image in a variable called 'source'.

What I want to do is manipulate it so that it just returns the file name image.jpg. How can I achieve this? I tried split() to see if I could split it into an array using the / as a separator, but this didn't work.

Obtain The Tag Name Of The Dom Element That Has Focus

Jan 4, 2008

I am working on a firefox extension. The job is to sit in the status bar and as I type into any form on any webpage, listen for keyboard events, then modify the key pressed by mapping it to some foreign unicode character and then sending it to the form in focus.

As I see it, there are two ways I can achieve it.

1) Capture the event, modify it and then send it and not be concerned with the form in focus.

2) Capture the event, prevent default action., find a unicode mapping for the key pressed, find the form in focus and based on the type of form, call a method to explicitly insert the mapped character at the cursor position.

Right now I am not able to find a way to do either. Once I get the focused element, I can do something to it. But I am not yet able to get that. I even tried document.activeElement, but it doesnt seem to work in firefox.

JQuery :: Obtain Object (key) Names?

Oct 16, 2009

I;m looking for a way to obtain key names from a JSON object:

eg
"options": [
{"Option1" : ["Value1", "Value2"]},
{"Option2" : ["Value3", "Value4"]},
{"Option3" : ["Value5", "Value6"]}

[Code].....

Prototype seems to have a keys method which would achieve what i'm looking for. There are also a few pages which attempt to address the issue with JQuery, such as: [URL] However i was only able to retrieve the numerical index of the array elements using these methods (vs their name).

Read Current DIV - Obtain The DIV You Are Currently Hovering Over

May 3, 2010

Is there a way to obtain the DIV you are currently hovering over using Jscript?

Basically I have ten thumbnails that I'd like to change the borderColor for using onmouseover. Instead of having to specifically create a DIV for each thumbnail (#tmb1, #tmb2, etc.) and then having to attach a separate function to each one (document.getElementById("tmb1").style.borderColor = "#660000") I'd like to be able to detect the DIV the mouse is currently over and change the borderColor of that.

I have over thirty pages, each with 10-15 thumbnails, which is why I'm trying to come up with something more generic.

Extract Filename Of Html

Jun 17, 2007

This is a simple script I though of to get the filename of container for html.

Note: this only is tested on mozilla firefox 2 on windows vista

document.write("<a style='display:none' id='zFilenameFinder1' href=''>q</a>");
document.write("<a style='display:none' id='zFilenameFinder2' href='b'>q</a>");
var zDocURL = document.getElementById('zFilenameFinder1').href;
var zCompareURL = document.getElementById('zFilenameFinder2').href;
zCompareURL = zCompareURL.replace('b','');
var zFilename = zDocURL.replace(zCompareURL, '');
alert(zFilename)//filename handler


it works by creating two relative urls. one's href is blank, which when called by link.href returns the absolute value, giving the absolute link the page, then you compare it to a link that has a relative href of "b" which can be compared to the other link to give you the whole url

Set The Cookie Filename With JavaScript

Feb 16, 2006

Is there a way to set the cookie filename with JS?

Currently it is setting it as 'asp/' (my directory). Can i specify it?
This is my code:

function setCookie(NameOfCookie, value, expiredays)
{
// Three variables are used to set the new cookie.
// The name of the cookie, the value to be stored,
// and finally the number of days until the cookie expires.
// The first lines in the function convert
// the number of days to a valid date.

var ExpireDate = new Date ();
ExpireDate.setTime(ExpireDate.getTime() + (expiredays * 24 * 3600 * 1000));

// The next line stores the cookie, simply by assigning
// the values to the "document.cookie" object.
// Note the date is converted to Greenwich Mean time using
// the "toGMTstring()" function.

document.cookie = NameOfCookie + "=" + escape(value) +
((expiredays == null) ? "" : "; expires=" + ExpireDate.toGMTString());
}

and this is how i call it:

setCookie('OpenJaw', 'true', &#391;');

Restoring A Filename And Path On A FORM?

Nov 14, 2010

how to save form values in cookies, etc. for use when re-displaying the forms. for example, after an error has been detected. Naturally, PHP allows you to do this with $_SESSION variables.

But no one seems to have cracked the problem with FORMs having file uploads. Browsers will send the file to the server and the name, but not the path on the client computer (I suppose for security reasons).

So, if you want to re-display the page, you can fill in all the form data in your PHP script so that the user doesn't have to re-enter everything. But, since your PHP script only knows the NAME of the uploaded file, and not the path, whatever your fill in for the "xxx" in <input type="file" value="xxx" /> will be wrong.

Specify Word Doc Filename In Save Dialogue Box

Sep 28, 2010

I have a webform that creates a word document as it's ouput (yes I know it only works on IE).
function createWordDoc(){
Doctxt = "some text here"
var w=new ActiveXObject("Word.Application");
w.Visible=true;
w.Documents.Add();
w.Selection.Font.Name="Times New Roman";
w.Selection.ParagraphFormat.Alignment = 1;
w.Selection.TypeText(Doctxt);
w.Documents.Save();
}

My issue is with saving the file. At the moment, in the above code, it opens the save dialogue box, and populates the filename field with the first line of text in the document. What I want to be able to do is populate the filename field with a variable filename created by the function. I've tried the snippet below, which works with the dynamic filename, but it autosaves the file to "My Documents" folder without prompting. I need to be able to allow the location to be changed.
var FileName = "Myfile.doc"
w.ActiveDocument.SaveAs(FileName);

Pull Variable From Cookie Filename?

Oct 11, 2011

I'm working on an internal website at work and employees have a cookie created when they login to the customer support tool. The filename is cookie:username@domain.com/ and I'd like to use javascript to pull a variable for their username to plug into a URL for a unique link when they're viewing one of our intranet pages.

@domain.com/ will always be the same but I don't know how to pull the unique username from the filename of the cookie. I don't need to actually read the cookie.
