The first alert seems to contradict the second and third alerts:
Code:
alert(isNaN(null)); // returns false
alert(parseInt(null)); // returns NaN
alert(parseFloat(null)); // returns NaN
alert(null.toFixed(2)); // error: null has no properties
I have a numerical value (lets say £11.60 for example) that is passed to another page (ie booking.html?price=£11.60). What I want is for that value to have a certain number added to it. The code below is what I have tried to do this, but I only get the value with the numbers added to the end of it (ie £11.605 instead of £11.65). I need the .replace to stay there as it filters out the random characters that appear because of "spaces" that are passed along with the other variables. Ive tried parseint() and parsefloat() but always get NaN as a result.

I need to get the order of rearrangement for an array after sorting:
Eg.
[a, c, d, e, b, f] sorting order will be [1, 5, 2, 3, 4, 6 ]
I'm implementing it as follows:
Assuming valueClass is class name for elements with values that need to be sorted:
$('valueClass').each(
function(index){
var eachVal = $(this).text();
arraysort[index] = [eachVal, index];
[Code]....
PS: All i need is sorting order for an array that can either be all string or all integer (with a boolean to let me know if its the latter or the former). These are the only constraints.
what i would like is to achieve what has been implemented here : [URL] the problem is that, although i have the numerical values (%) that indicate the traffic that passes through a link available as data, how to display them onto the google map?

How to use JavaScript to dynamically change the colour of the numerical meter readings to show if they are above or below the target value entered by the user in a text box on the page.Those below should be shown in green,those above in red and identical values may be shown in amber.This functionality must be completed client-side without a page submission to the server.You must consider putting the values in a particular tag and then using the getElementsByTagName() JavaScript method.
View 5 Replies View RelatedI did find the javascript twice in my code, once in the header and once here, so i removed it from the header. I also changed to src to the full url. But i am still getting this and i dont know why. the file is located in the root directory. found a solution. basically Internet Explorer is crappy and doesnt like the setAttribute property so had to change the onchange handler by directly changing the attrbute for the object like so.object.onchange = function() {}i have no idea what they means, does that mean i need to change swfobject.js or does that mean i have to change my xml request. and if it is the swfobject i have no clue what they mean or what lines

I put a long script but the problem is small.
var book1 = bobj1.value;
var chapter1 = cobj1.value;
var verse1 = vobj1.value;
var book2 = bobj2.value;
var chapter2 = cobj2.value;
var verse2 = vobj2.value;
[Code].....
I don't know if this is written properly: if(bcv[a]!= ""){ The reason this is happening is because the error shows: Error: cobj1 is null Source File: [URL]
My code is in the attachment alex.txt.When i press the button for first time it gives me error: 'null' is null or not an object. But when i press it again or refresh the page and press the button it gives me the result that i expect.When i change the var pdbfile1,2,3 values(for example with 2x4n;3gis;1crn) and press the button again there is the error again and i have to refresh the page again.

View 18 Replies View RelatedI have this reg exp
var queryAdd = /?stationval=([^&]+)/.exec(url)
it should return
queryAdd[0] = '?id=AY'
queryAdd[1] = 'AY'
which works fine, as long as there is a stationval in the url, but if the user has not yet specified it stationval= nothing, which is throwing the script saying that 0 is null or not an object.
How do I catch this eventuality? I have tried if(queryAdd[0]==0) and if(queryAdd[0]==null) but get the same error
How to check for null attribute in form input field using IE
this does not work in IE:
var curr_id = tablecells[i].getAttribute('name');
if (curr_id != null){
....
}
I remember using if statements with null in it. For example, at one
point I used this:
if (value == null) {
value = "something";
}
document.write(value)
However, this script causes an error in any browser. Why can't it
correct the value like it should?

When are you allowed to use null as a namespace in functions like createElementNS? Most of the time you see people using a namespace all the time or null all the time. But I can't seem to find a real rule...
I use the xhtml-namespace for xhtml and the svg-namespace for svg, but I saw a lot of examples using 'null' as a namespace... Is that allowed?

The Typekiezen is a weird one; if there's a nicer/better way of writing that, that would be nice, but it happens this form input does several things when it's clicked... the others only bring up an associated value for the option chosen so they're simpler.Does anyone know why IE can't read this " document.getElementById(Begrafenis.kosten[input.id][val].hide[result])" ...or another way I could write it so that IE does get it. Basically, the code needs to grab the ID's "Postal" and "Box" so the show/hide scripts can DoStuff to them.
Even if I do a bit of
if (value !== null) {
Basis.add/removeClass(value, 'none');
}
this still isn't going get IE to do the right thing, just remove the error.
I have a site that is supposed to be 'real-time' which has a frameset
of 2 rows (the bottom row is 1 pixel so essentially invisible to IE
users which is the requirement for the product). The bottom frame
refreshes using an http-refresh every 15 seconds. If new data is
available on the server, it tells the top page to refresh. For checks
and balances, the top frame has a form at the bottom of the page with a
'clockBox'..which is essentially a text box that gets updated every
second so it looks like a timer. When the bottom frame refreshes, it
waits 5 seconds then resets the top counter to 0. The top counter
continues to count. If the top counter gets to 30 (which it never
should unless the bottom frame gets stuck), it refreshes the bottom
frame. Code:
Basically i'm trying to draw a box over an image which
is turning out to be a nightmare. The problem i'm getting at the moment
is that i'm creating a line with <div which works when it's not hidden
but I need to be able to make it hidden so I can use layers to show all
when it finished drawing to make it smoother. This is how some other
scripts are doing it that i've seen. So i've got it drawing a line and I
need getElementById to pick out the layer but it's only picking out NULL
with the one i've got enabled below. I've tried the others but they just
come out as errors. I need to get top2 which is the <div line to show
itself but I can't seem to reference it by getElementById. I use linux
mozilla so i need it working in mozilla as well as windows that's why
i'm using getElementById. My code is below any ideas anyone?
I am using jQuery for the first time, I think I have everything setup correctly and I have two datepickers on my page that appear to be functioning correctly and displaying the appropriate dates, but when I attempt to get the values (text) of the textboxestheyare always null even thought the correct dates show in the controls onthe page. What am I doing wrong? Do I need to include my code?
