I'm using a datepicker and I'm using $(this).html() to get the number of the day inside of a TD. What I want to do is take that number and add one to it. Every time I use var thenum = $(this).html()+1
I get something like 21 instead of 3. Is this possible? I've even tried using $(this).html().toString()

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.
Here is what I've done so far:

I'm looking for a way to grab a number from a string, although this number
is not at either end of the string.
Here is the string in question: var el = "v4Function_Name('argument3')"
Here is a substring that returns the number ( the 3 ) successfully...
var number = el.substring(el.lastIndexOf("ent")+3,el.length-2);
Seems very ineffecient to do it this way, and better to find a lean elegant
way using replace(); How does one go about getting a value inside of a
string with regular expressions? .. or is there a better way?
Here are a couple of the many expressions I have failed with...
var pat = /^[^ent][0-9]*$"/;
var pat = /v4Function_Name('argument([^0-9]+)'/;
var number = el.replace(pat,"");

I've been searching for about 3 days on this topic. I'm trying to get a template field inside of an ASP.Net detailsview control inside of an ajax updatepanel to work with the jquery datepicker. Very frustrating! I'm using VB with VS 2010. I can get the datepicker to work fine with a simple text box inside of an update panel but when I put it inside of a detailsview control it stops working.

I can't simply replace any "180" with "800" because the value might be present in the lid or isbn.So far I've pretty much cut the url up in pieces (I reckon it could be done a lot easier), but I'm stuck with replacing it.[code]

When updating our agency's webpage daily, [URL] I am looking for a shortcut to save time.. When I update air quality numbers. I have to put the conditions. Ex.. 50 = good 100= moderate etc etc. As you see here(bold and underlined)
[Code]...
Well instead of having to type good or moderate every-time to correlate with the numbers, I want to find a way the category can automatically default correctly when I put in just the number. Ex, if I put in the number 100, it automatically knows to issue/ put Moderate with out me having to type it. I semi wrote a code .. Yet can't seem to know how to execute. Seeing if Maybe I can get some assistance.

I have a function below where every time a question is submitted, it will add a new row in the table with a textbox which allows numbers entry only. My question is that I don't know how to code these features in this function:
I want the text box to be between 0 and 100, so if text box contains a number which is above 100, it will automatically change the number to the maximum number which is 100.
Does any one know how to code this in my function below in javascript:

When I used toFixed() method on a number, I thought that this method round a number to a specified approximation, but I got a surprising result, the number became string! 15.23689.toFixed(2) ==> "15.24". So does it convert the number into string?
View 6 Replies View RelatedI am trying to figure out how to make a random number I can plug into a script count down from that number at certain times of the day until it reaches 0. I would like it to reset itself at midnight every day. I'm trying to make it work with a script I found on here that resets itself at midnight every day. So instead of it counting down too fast, it would count down to the next number after a randomly generated number of minutes until it reaches 0. But it wouldn't necessarily have to end at 0 at midnight. It could go from 845 to 323 at the end of the day at a slower pace. Is that possible?
View 5 Replies View RelatedI am working on a Phone Number Form. The link of script: [url]
Questions:
(1)I wanted to know if code this script so that instead of the phone number appearing as: (123)456-7890

consider the next code:
var obj = {};
with(obj) {
var x = 10;
}
print(x);
print(obj.x);
It prints 10 and undefined. Here, one could expect that obj.x get the
value 10. But it's not the case, because variable declarations are
placed at the start of function code (or global code), so the
previous code is equivalent with:
var obj;
var x;
obj = {};
with(obj) {
x = 10;
}
print(x);
print(obj.x);
You can clearly see now that x is placed in the outer context. But
consider the next:
var obj = {};
with(obj) {
eval("var x = 10;");
}
print(x);
print(obj.x);
I was expecting that obj.x would get the value 10 here. But no, it
gives the same output as the previous code. I tested it with
spidermonkey, kjs and ie jscript. Looking at the ECMA spec, I could
not find anything that describes that behaviour. Code:
Formerly I've been replacing characters with javascript using the following code.
paramString = paramString.split("").join("<sup>");
paramString = paramString.split("").join("</sup>");
So if the user on my website types 52 it would return the following value: 5<sup>2</sup>, or just, 5 how do I detect something like this. if they enter: 5 how can I detect the number "2" and put it superscripted past the number 5. so the javascript reads this: 5 and returns this: 5<sup>2</sup>
I'd like to make a Degree object that inherits from the Number object and uses the Number constructor but adds a .rad() method that returns the value in radians.

View 3 Replies View RelatedI want to know how to count to a number via jQuery. jQuery should get a value in a variable and then start counting to it in a fix time. for example the number is 500.67 then i should start with 1 and the add up until it reaches 500.67 in 5 seconds, so the final value is not visible at the begining but at the end. the numbers can b between 1 and about 1 million but it should always need 5 seconds to count to it (must not be always +1 but i should count smooth).

I'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 this:

in here I need to change the image by the number:for example: The number is 1 then:
1. ALL images are: <img src="/website/path_off.gif" class="test">
2. the FIRST image change to : <img src="/website/path_on.gif" class="test"> and so on..
I want to compare the total number of checkboxes with the number of checked checkboxes of a certain nameI use these 2 functions:
alert($('input[name=checkItem]').length); // To get the total count
alert($('input[name=checkItem]:selected').length); //To get the total selected count
The first one works, the second one doesn't.
