I am trying to read all the navigator object elements
1. Using the navigator.length returns undefined, cant use for loop;
2.Using and array of known elements like
var a = Array("appCodeName","appName","appVersion");
I seem to miss something to get it combined like navigator.a[i]
every time I try and alert:
[ { number:0, secondnumber:0 }, { number:2, secondnumber:1 }, { number:1, secondnumber:2 } ]
it just shows [object object], [object object], [object object]. Why is this and what can I do to make the record be shown as it is above in an alert?
Is there any way to get the variable name of an object from inside the object?

navigator.userAgent returns information about the user operting system,
Browser etc.
Usually you get somthing like:
Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)
or
Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; .NET CLR 1.0.3705; .NET
CLR 1.1.4322)
or
Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.4) Gecko/20030624
Netscape/7.1 (ax)
imho there is too many information, most of it confusing for the user. What
I would like to do is, evaluate the information and
reduce it to the opereting system and browser version.
e.g.
MSIE 6.0, Windows XP
or
Netscape 7.1, Windows 98
obstacles:
- As far as I know, the structure of the data returned by
navigator.userAgent depends on the browser.
So a specification for each browser would be a good starting point, any
ideas where to find?
- Why do I get "Windows NT 5.1" instead of "Windows XP"? Any other
synonyms?
I neither tested it on macs nor linux systems...
Why is /MSIE (5.5)|[6789]/.test(navigator.userAgent) true
when navigator.userAgent == "Opera/7.0 (Windows 2000; U) [en]" ?
I need to know that navigator (IE or FF) was restarted or just know that cache was deleted.When I change sth in JS script, my old script is still in user navigator cache. I need user to use my new script, so he/she must clear cache or restart navigator (or maybe sth else). I show allert() that he/she mast do it, but how can I ckeck he/she did it?
View 1 Replies View RelatedI'm using the $ function to get an element using ID:
function $(e){return document.getElementById(e)}
I'm trying to extend this function to use it like this:
$("myID").s("div");
In order to get all the elements that are DIV inside element ID "myID". So I wrote this:
$.s=function(es) {return document.getElementsByTagName(es);}
But that's not working.
What did I do wrong?
Also, Is it possible to to somehow extend it to use with endless number of inside tag/id? like: $("a").$("b").s("div").$("c") ?
I was wondering how to split the elements inside each other, so that each of them has its own background color. What I'm trying to do is to highlight background of each element onmouseover. Up till now I haven't managed to do it properly - for example, I have a table cell with a hyperlink inside it. When I point to the cell - background changes, however, pointing to the hyperlink leaves the cell coloured - which is what I don't want. I'm trying to use this code:
HTML Code:
onMouseOver="this.style.backgroundColor='yellow';" onMouseOut="this.style.backgroundColor='white';"
Where can I find a list of valid names for Navigator.AppName?

ps I know the 2 div's are the same, but this is only for testing.
I am trying to use the remove() jquery function.
I appended elements inside this div. But I want it where if a check box is checked then that element which is an a tag html element that will be removed.
The problem... when lets say append 3 <a> tag elements. when I remove all 3. Then append like 4.. I see like gaps. like I want it where if I delete the element it will float upwards. what that means that if I got 3 elements and I delete all 3 and then append 1 new one... then that new one should be shown at the top of the div. Not displayed a little bit lower then where the 3rd element we removed was located at.
It seems like that html code that is appended still stays there for some reason.
I have a fieldset with a bunch of input's inside.
I am wanting to put all of these elements inside the fieldset into an array.
Then once I have that array use a for loop to iterate through each of the elements values and display them with alert.
This is what I have tried, but am expecting to be a fair bit off the mark.

I'm working on an exercise I need to have finished pretty soon. The concept is simple: online bookstore with cart etc. It's written on php, using JS and mysql.
Each time I view a book's details, I can add it to my cart, where I can also alter it's quantity.
The code for my cart is this:
PHP Code:
As you can see, each time I choose a book to add it to my cart, a new span will be created, to hold the info of this book. What I need to do with the ManageItem js function, is to update the total cost at the bottom of the page, but I can't seem to be getting anywhere.

I am trying to test changes to my site (made only on my local machine so
far) in IE v6, Mozilla 1.6, and Opera 7.5.
When I test "navigator.javaEnabled in IE it corretly reports true/false
depending on whether javascript is enabled.
However, both Mozilla and Opera *always* return false. How can I properly
test to see if javascript is enabled/disabled in these two browsers? (If you
have a reference on the web, please point me to it as I've spent several
hours trying to find what I need.) Code:

View 3 Replies View RelatedI am having troubles manipulating DOM elements inside a variable. I have the following code:
var
$content =
pages[pageId].page;
$('.widget_inline'
[Code]....
Inside this html string there are multiple id's that I have to change. The .each finds the rightelements and the manipulation seems to work when I do a console.log onwidgetElement.However the actual $content remains unchanged. I probably made a very obvious mistake but I can't find it.
Hereyou can find the whole example. By clicking onClick to Addyou will clone 100 times the elementtrackOn; then it will be append to the tabletracklistOn. Unfortunatly, if these elements are inside aformyou can see that the time is very high before the process is finish.If I remove the form, is quite immediate. Why this behaviour? How can I fix this problem? P.S. I don't know why, but I can't paste the whole code here. So follow the jsFiddle link please :)

I have a complex JS object. It manipulates the page DOM. Inside it I have many repetitive selections spread across functions. I would like to cache the selectors to enhance performance. How do other people do this? I can cache on the function level but not the object. When I try to cache on the object level I seemingly end up with stale selectors that while defined don't actually work.
My gut is that I can only cache on the function level?
what I have read does not deal with caching inside a JS object.
