Creating A Total From Query Strings?
Nov 28, 2011I'm working with a simple shopping page. I basically need to add up all of the values that are found in my query string, and display them as a total on my page. I know how to retrieve each value individually, however I'm a little confused on how to add up the values that are only found in the query string.
Please keep in mind, I'm very new to javascripting, and probably won't understand in-depth coding.
I have a lot more code to go with this, but I don't think it's required for my question.

Stop Tabs With Query Strings From Reloading Page?
Aug 18, 2009I have a set of tabs that are set with an href that adds a query string to the url such as "?t=1", meaning the first tab is selected.
Technically it works just fine but every time I click a tab it reloads the page and I'm not entirely sure how to stop this.
I'm using a jquery plugin to handle the query strings. Here's the plugin [URL].
Here's the piece of the code that matters:
var url = location.search;
var tab = $.query.get('t');
init(tab);
function init(tab){

Strings Not Replacing Strings
Sep 25, 2007I've been learning javascript for about a week and I'm really struggling right now. This is a homework assignment to help in learning loops and arrays.
What I want to happen is when a form button is hit it will replace the array from the one previous instead of just adding to it. Hopefully that makes sense. What do I need to do? here's my code....
Strings And Numbers...?
Feb 3, 2006I'm having difficulties arithmetically manipulating form element values.
I've entered data into the form, and I fetch them using a js, as:
p7Left = Number(document.form1.elements["p7_left"].value);
p7Right = Number(document.form1.elements["p7_right"].value);
...
...
scoreLeft = Number(document.form1.elements["left_score"].value);
scoreRight = Number(document.form1.elements["right_score"].value);
Then I add these as follows:
scoreLeft = Number(scoreLeft + p&Left + ...... +);
This does what I want; without the operator 'Number' I get a concatination
of the various variables (as expected). Is there some way of globally
defining all variables as numbers instead of strings?
Strings As Arrays
Mar 6, 2007Safari and FF seem to allow this:
var wiggy = "ABCD";
ch = wiggy[2]; // ch will contain the character 'C'
however my JS book seems to insist that I do this:
ch = wiggy.charAt(2);
and indeed doesn't appear to mention the first method at all.
Since for my particular purpose I want to treat the string as an array
of single characters, I prefer the first method rather than the second.
Is there any reason not to pursue this approach?
Comparing Strings
Apr 16, 2007I have two strings that I need to compare and modify when there is a
matching value in the two. If strA = ??,' then I need to remove
the value ??,' from strB and the new value would be strB =
??,12935'
strA = ??,'
strB = ??,12937,12935' (these could be any values in any order)
I'm not sure where to begin on this.
URL Variables & Strings
Nov 2, 2005I was wondering if someone would be so kind as to help me out in understanding a few things about sending a variable through a URL..
firstly:
i have two pages on page1.html i have a link which is:
window.location = "page2.html?name=yournamehere";
on page2.html how how would i be able to access the variable "name" ?
i know the following code works for strings, but i want to be able to directly access the variable that has already been assigned a value.
function parse(){
var Loc=this.location.toString();
var URLarray1=Loc.split('?')[1];
}

Creating Arrays From Strings
Feb 15, 2006How would I put 2 strings like this into 2 separate arrays like my
examples below?
Div10,Div11|Div2,Div3,Div8,Div4,Div12,Div1,Div5|Di v3,Div5,Div9
France|Germany|Norway
var DivOrder = new
Array("Div10,Div11","Div2,Div3,Div8,Div4,Div12,Div1","Div3,Div5,Div9");
var DivNames = new Array("France", "Germany", "Norway");
Is There A DeHTMLize Function For Strings?
Apr 19, 2006Code:
a = document.createTextNode("< somestring >");
....will transform < into < and > into >
When I want to read that node later, I can only get it back in
this form: "< somestring >"
Is there a function that transforms such strings containing
HTML codes back to normal strings? Something like:
string deHTMLize (string);
What I need is to quote and send a part of the document when
user clicks a button, so I need the string without codes.
Passing Data In Strings
Jul 27, 20071) To populate a dropdown control that's on a page with data coming
from the database, the developers concatenate all the values separated
by a pipe character and pass the string to the JS function, which
splits the string and adds the values to the dropdown control.
I think this is not a best practice b/c:
A) If the data returned from the database results in a string that's
too long, it could exceed the limit of the JS string type and some
items would be missing from the dropdown.
B) If by any chance, the data from the database contain pipe
character, it would result in extra elements inserted in the dropdown
control.
Is there a better way to pass data to JS w/o relying in strings? How
can these practices be improved?
Transferring Strings From Php To Javascript
Jul 20, 2005i got this javascript-function that changes the entries of a selectbo
depending from the selection of another selectbox:
function changeBezug(selectedEntry, '$exhibits', .....) {}
the string '$exhibits' holds all the entries for the option Entry i
the first selectbox;
Unfortunately i get javascript error unterminated string literal an
the error pointer points at the first apostroph:
function changeBezug(selectedEntry, '
I tried replacing all special chars in $exhibits, even putting th
string directly into the function code with php and tried using quote
instead..
Now im out of ideas!
Maybe im using the wrong replacement for the apostroph...
i use ' is that wrong? i also tried ' to no good either..
what's the right one?

Pass Strings With Spaces Through Url?
Jun 16, 2009the title says it: is it ok to pass strings with spaces trough url? i tried it and it seems to work, but it also seems to me that more correct way to do it is to use '+' instead of space since that's what php get method does. i'm using window.location to redirect to another page.

Sep 20, 2009I'm trying to convert a string based on the contents of another string. For example, I have two strings - "Purple" and "Orange" and a variable "P" - I want the script to look at the word "Purple" and everytime is sees the letter "P", assign this to a third variable (result variable) - if the letter it's looking at is not a "p", I want it to take that character from "Orange" and add it to the result string. So the result would be "Prapge". This is the code I have so far, and it doesn't work, absolutely stumped as to why ...

Oct 2, 2011I have this code for HMTL5 Canvas, however this is a JavaScript directed question not a Canvas question.

var cxt=c.getContext("2d");
cxt.moveTo(0,400);
cxt.lineTo(50,a);
cxt.lineTo(100,b);

That will draw a line graph, however I want to get the coordinates from a variable in the URL. So it may be example.com/a=500&b=600 . How would I retrieve these two variables and then insert in to they're respective places?

Sort Outer And Inner Strings Alphabetically
Sep 2, 2007Is it possible to sort outer and inner strings at once? The sorted output should look like the following:
<category>Bars</category>
<name>Alpha Bar</name>
<name>Beta Bar</name>
<category>Cafes</category>
<name>Ara Cafe</name>
<name>Zeta Cafe</name>
Categories and names are both properties of one and the same array element.
I have the following compare function to sort the outer categories.
function compareCats(a, b) {
a = a.category;
b = b.category;
if(a == b) return 0;
else if(a b) return 1;
else return -1;
}
This is working fine. But I really would like to include the inner names in the compare
function without changing the structure of the array - if it could be possible. If not - what would be an efficient way to solve the problem?

JQuery :: Highlight Certain Text Strings?

I want it to highlight either the first word only, or just the line that the @ symbol is found on.
