How To Find Website Root Path

Jul 23, 2005

I have a problem with an application i'm working on (Asp.net using
vb.net for developing). I'm normally used to doing middle tier
development, so my javascript skills are not up to par. Here is my problem:

I have a javascript file called 'PMP/Scripts/Popups.js' (pmp is the root
of the website). In that file is the following function:

function OpenTutorial(sTutID)
{
var sURL = '../support/tutorials.aspx?tutid=' = sTutID;
var sProperties = 'center:yes;etc..'
window.showModalDialog(sURL, self, sProperties);
}

where ../support is acutally pmp/support.

Most of the website pages are located in sub folders from the root of
the website. When editing is to be done on a record, a popup window is
called from the main page. the popup pages are in another sub folder
(i.e. pmp/review would be where review.aspx resides and the edit page
would be located at pmp/review/popups). We give the user a tutorial
icon to click on which calls the OpenTutorial function on a button click
event.

The problem is the tutorial popup page won't load properly when called
from another popup page. I've tried variations of location.href,
location.pathname, location.hostname etc.. but can't seem to get the
pages to open correctly. The most common error i get is that the url is
not correct. here is a sample of the urls being called by the function:

JQuery :: Using Closest() Method - Root 2 Don't Get Selected

Jun 16, 2011

I have the following script using the closet method. It works fine for the inner most li tags however the outer li tags don't get seen? So both Root 1 and Root 2 don't get selected but the Sub Cat 1 and Sub Cat 2 get selected fine. I'm sure I'm missing some code to make this work.

Calculating Root Values Beyond Math.sqrt

Dec 14, 2007

Well, it's been a while since I last visited CF, but I'm finally back and, for the life of me, am drawing a total blank on something that seems like it should be fairly easy to handle.

The Math.sqrt() function works just fine if all a person needs is the Square Root of a number, but what about needing the Cube Root or even a 4th Root of a number?

My first instinct was to use the Math.pow(x,y) function with a negative value for "y." For instance;

var z=Math.pow(27,-3)

This should return a value of 3. Unfortunately, this doesnt seem to work when I tested it through the W3 reference pages, so I am looking for a clue as to how I might go about finding such values, or if it is even possible through Javascript.

Dhtml Content Not Working In Iframe (IE) But Works In Root Document?

Mar 3, 2010

I am using a dhtml "Image Slideshow", and I was really happy with I customized its layout to my needs, and it runs perfectly on FF and on IE (wich is very important for me, since in my country most of people still use IE). Check it hereHowever, when I insert the slideshow in my design, it stops working on IE (working in perfection on FF):I am using the original slideshow file in an iframe.(before I tryed to paste the code directly into the page, but it didn't worked, so I thought using an iframe would work, because the code of the original document would be intact)

Embedd An Address Navigation Bar On Top Of Pages Visited From Root Site?

Sep 2, 2010

I have what some would identify as a Kiosk machine running a browser in full screen(true full screen, no address bar visible). It serves as an internet cafe machine, with unique users and a login system.

What I'm looking to do is when the user leaves the root site (via clicking a button), to embed a frame at the top of the page with an address navigation bar, so I can track the time the user spent browsing. I'm exclusively using firefox, and I'm not concerned with support for such functionality in other browsers.

I assume I can achieve this with javascript, jquery, or ajax, I'm just not sure which to start with and how to begin planning the execution.

Textfield Name Containing Square Brackets

Jul 20, 2005

I'm hoping that someone can help me with a question I have about javascript syntax.

I got an html page that uploads an image and some text field to a database.

What I'd like to do is modify the content of one of the textfields prior to it being submitted to the database. Specifically, I need to append the contents of one of the fields to another.

The problem that I've encountered is that the textfield name contains square brackets , extra_fields[Price]'

I've identified the square brackets as being the problem by changing the textfield's name to one that doesn't contain square brackets ,extra_fieldPrice for example and the script works fine.

Unfortunately, in the real world application of this page, I can't change the textfield name.

The specific part of the html page that's giving me problems is:

Rotate A Triangle / Square?

Oct 10, 2011

I know very little about javascript, but was wondering if something like this can be done?

Would it be possible (with mootools or jquery) to have homepage that will rotate its home page content forwards and backwards based on either triangle or square? ie, you can rotate through 3, 4, etch home pages?

Sort of like a slider, but it rotates off a center axis of the triangle or square?

JQuery :: Square Brackets In Selectors?

Apr 9, 2011

While trying to get a selector to work with ids that include square brackets, I searched the forum and found that I needed to escape the brackets with '\'. However, while this works with my fiddle: can't get the exact same selector to work within my page in either FF or Safari. I've triple-checked the id and it is correct; I know that jQuery is working on the page because changing the selector to$('.nameinput') gives the expected results. can't change the id because I'm working within an existing application; I know I could add a class to the input and use that as the selector instead. I'd prefer not to and would just like to figure out why this isn't working.

Need To Remove Empty Square Symbol From Text

Apr 19, 2010

I have been looking for days for a way to do this but have made no progress.

The text looks fine in php but when displayed by javascript, some of the spaces are shown as an empty square symbol.

I have tried the following to change any unusual character to a space, but it doesn't help. code...

I believe that the character is created by a javascript-based editor when either the delete or backspace key is used to make an edit.

I have this strange symbol in many articles so I need a way to deal with this (the articles display fine when displayed by a php CMS).

I'm using javascript to show a preview of the article as a link tooltip.

Code:
var title = note_title.value;
// validate periods and brackets

Newline - Does Not Working After Retrieve A Record That Contains Square Symbol In The Database?

Dec 10, 2009

my javascript does not working after I retrieve a record that contains square symbol in the database. The square symbol should be a newline in a textarea. This is how the record "looks" in the table: [URL]

I am inserting the record using ASP and the value with square symbol is the value from a textarea with newline/enter. After that I retrieve the value using ASP and pass it to javascript and then the page is not working. If I retrieve other record which contain no square symbol then the script is working.
