Strings Not Replacing Strings

Sep 25, 2007

I'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, 2006

I'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, 2007

Safari 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, 2007

I 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, 2005

I 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];
}

Is There A DeHTMLize Function For Strings?

Apr 19, 2006

Code:

a = document.createTextNode("< somestring >");

....will transform < into &lt; and > into &gt;

When I want to read that node later, I can only get it back in
this form: "&lt; somestring &gt;"

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, 2007

1) 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, 2005

i 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 &apos; is that wrong? i also tried ' to no good either..
what's the right one?

Pass Strings With Spaces Through Url?

Jun 16, 2009

the 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.

Compare And Replace Strings

Sep 20, 2009

I'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 ...

Strings - Get The Coordinates From A Variable In The URL

Oct 2, 2011

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

<script type="text/javascript">
var c=document.getElementById("myCanvas");
var cxt=c.getContext("2d");
cxt.moveTo(0,400);
cxt.lineTo(50,a);
cxt.lineTo(100,b);
cxt.lineTo(150,390);
[Code]...

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, 2007

Is 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?

What I want to do specifically is add a CSS class to strings that start with an @ symbol. I can't seem to find any examples online and I haven't had enough experience with jquery to figure this out on my own.

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

InnerHTML / DIV Size Changing To Various Strings

Dec 21, 2010

I was playing around with some onmouseover/onmouseout and setting innerHTML to various strings depending on what has been mousedover/out. The DIV for the innerHTML was above the items being onmouseovered/out and because the strings sent were of different lengths, sometimes a one or two line wrap would happen and everything below it would be resized accordingly creating a horrible effect. For reference, what is a good way to approach building pages which are immune to this effect?
