Does anyone know of some way of referring to the current line number in a javascript? This would be a handy debugging tool: whenever a function threw an exception, it could say "ERG! Something wrong on THIS line".
View 3 RepliesI want to write a function that will let me position my cursor in a textarea on a line number. I would need to use on a textarea component to do this.
I'd like to popup a dialog in JS so I can ask the user what line number and then have the cursor go to that line - is this even possible?
I need help finding where an error is occuring in my code. I use a
try-catch block like this in my global.asa:
} catch (e) {
Application('errormsg') = ("An exception occurred in the script. Error
name: " + e.name
+ ". Error description: " + e.description
+ ". Error number: " + e.number
+ ". Error message: " + e.message); }
And this is what is SOMETIMES returned when I display
Application('errormsg'), the rest of the time, it works:
An exception occurred in the script. Error name: Error. Error description:
Path not found. Error number: -2146828212. Error message: Path not found
But I don't know which path is not found! (I'm using the filesystem object
and importing data from a file into SQL.) Is there a way to display the
line number of the error or more details? Or do I just have to try to catch
the error by going through each bit of code?
I'm playing around with edit in place and have a list of information that is generated by a php loop. Each list has a unique ID number at the top that i need to send back to my php script. I've put the ID number in a hidden form field at the top of every list and i'm trying to read it using .val() I've used .prev to get the line ID but can't seem to get ID number.... I thought it would be something like this but i can't seem to figure it out... i $(this).find('.Id:first').val(); usally work my way though stuff but this is making my head hurt.....
View 6 Replies View RelatedI've made a function for getting a ID for each sibling in a tree. Lets look at this DOM:
<ul>
<li>Five</li> //sibling ID 1
<li>Six</li> //sibling ID 2
<li>Seven</li>//sibling ID 3
</ul>
Here is the function:
function getSiblingId(elm) {
return $(elm).siblings().size() -$(elm).nextAll().size() + 1;
}
And here is how I use it:
var id = getSiblingId($('ul li:first-child')); // id = 1
Is there a more elegant way to get the same result? The work done in the getSiblingId-function has a lot of overehead.
I have a page has multiple slide shows in it, and have written a little script to loop over and implement the function. I'd also like to diplay the current slide number under each sideshow ("2 of 5 images"). I tried a few ways to go about this (using the variables that should be floating around pager or prevNextClick). Neither worked. In the past I've had success with idx etc

i want each column in an array like { 001203,024353,092434 } so total 3 arrays.

I create eLearning materials which are given away as a communty service to help people improve their health. A typical eLearning project has a few educational screens (using a Learner Management System-LMS-template) and an interactive exercise (on an external web page-htm or html-usually accessed by button which navigates to the exercise's URL).
The interactive exercise should only be accessed from inside the eLearning lesson using the button, because it requires understanding of the way it works plus important cautions to assure proper use. I need to prevent the use of the URL outside of taking the lesson (for example, someone taking the lesson acquires the exercise's URL from their browser history and then may give this to others who access the exercise directly-without necessary knowledge and cautions).
I tried document.referrer, using JavaScript. Using the referrer URL from inside the lesson and adding the JavaScript to the exercise's htm code worked OK in FF, but not in IE 8. In FF, if the referrer was not the correct single URL from inside the lesson, then it redirected; if the correct URL, the exercise appears.
The JS code follows:
<script language="JavaScript" type="text/javascript">
<!--
var oksite = "http://www.mysite.com/xyz/courseidxxxxx/yyyy/zzz.html";

In IE 8, I was not able to get it to work. Using an alert, I noticed that the referrer in IE 8 was blank.My web hosting (GoDaddy) is a shared Windows hosting. I would have to upgrade from IIS6 to IIS7 to use PHP. Bigger challenge: I've never used PHP. If possible, I would prefer to use JS. But, I am open to any suggestion that will help.I am also wondering if part of the IE 8 issue is that I am using IE 8 X 64?
I am using a third party shopping cart service written in php. I don't have access to the php code so I decided to use javascript to write a cookie. What I'm trying to do is have the cookie capture the referring URL and then keep it for a day and have it follow where ever the visitor goes in the shopping cart. Then when they check out, the referring URL will populate a form field and be returned as part of the form results. This way I can track where my visitors come from. My code is below and I'm adding it to the file designated as the head section. (The files I have access to must use some form of include but I can't use php in them - just html and javascript. I've tried.)
I have an alert in the code that suggests something to do as well as set the cookie. The alert comes up and the cookie is set but when you go to another page, the alert comes up again and another cookie is set. I just need to have it set once so when they fill out the order form, I'll know where they came from.
<SCRIPT LANGUAGE="JavaScript">
cookie_name = "dataCookie";

I want to append a string "&sid=xyz" to the current page URL if the referring URL comes from site [URL]. I have the following code -

query = query + "&sid=xyz";
}
However, the string is not being appended.
I have an object, "A", which contains another object "B", as an attribute.
How do I get a hold of Object "A" from within "B"? i.e. I need to refer to the object that B is stored inside from within B's code. Is there some superclass equivalent of 'this' that I don't know about? ('parent'?!)
I have very limited experience with Javascript. Can someone refer me to
info on how to determine the referring URL and the search term used by a

Is there any way to have the referring field blank when using the GetURL command?

I have a user that insists they have web applications that do this, and wants the one I'm building to do it too...
You have a table on an html form. As the user changes one or more fields in a table row and moves to the next line, the changed row should AUTOMATICALLY be sent back to the server and updated in the database.
If the user moves BACK to a line that's already been changed, and changed a field, a popup should display and ask "if the user really wants to change the field". If so, again, it should AUTOMATICALLY be sent to the server and updated in the database...
Ignoring the horridness of making that many round trips to the server and banging the database for every line, is there a way to AUTOMATICALLY do the equivalent of a submit and post the changed table row back to the php script?
I'm trying to create two bookmarklets:
1. Take the current URL of the page and open a new window with a URL based on the current page. Some examples (I use "->" to mean "this URL turns into that URL"):I plan to use these bookmarklets in sequence, first pressing 1 to log into the CMS, then pressing 2 to edit the current page.
I've put together what I think is an illustration of my problem at [URL] Quite simply, I need to be able to access the elements of the form without referring to them by ID as the whole form is intended to be cloned. I intended to do this using parentNode and childNodes[] together with the 'this' keyword. My understanding of 'this' in this context is that it should refer to the HTML element calling the function, i.e. one of the radio button inputs. However this gives the error "Error: this.parentNode is undefined"
