I have a string - comma separated - of array names. e.g.
var stringname = "array_one, array_two, array_three, array_four";
And I want to merge all the arrays named in the string into one big array.
(The string is produced via PHP as the exact arrays to merge may vary).
I've tried
var comboarray = comboarray.concat(eval(stringname));
But the eval()sn't working as I want!
I'm trying to concatenate two arrays but it doesn't work.
The code looks like

And the console output looks like:

But I was expecting:

Does anybody know why those two arrays won't concatenate?
I want to form a string that contains string and variavles.
Such as
var response = prompt("Enter Pcr Number?","");
var str = "'H:' response 'hi3.dot'";
So i want to fill in the string with the response.
I have two arrays and text variable.I need find all substrings from first array and replace them with corresponding substrings from second array in this variable.In php it would be$text = str_replace ($array1, $array2, $text);I know it is more complicated in javascript, and i have little experience in it.
View 2 Replies View RelatedI'm having some trouble generating unordered lists from arrays like this
testArray[0] = ["UL1","","SubUL1", "URL"];
testArray[1] = ["UL1","","SubUL1", "URL"];
testArray[2] = ["UL1","","SubUL1", "URL"];
testArray[3] = ["UL2","SubUL1","SubSubUL1", "URL"];
testArray[4] = ["UL2","SubUL1","SubSubUL2", "URL"];
testArray[5] = ["UL2","SubUL2","SubSubUL1", "URL"];
Basically the code should be able generate an unordered list such as,
UL1 SubUL1 (URL) SubUL2 (URL) SubUL3 (URL)
UL2 SubUL1 SubSubUL1 (URL) SubSubUL2 (URL)
SubUL2 SubSubUL1 (URL)
I had to work with the generating codes not the arrays, so the arrays could not be changed to make my job easier.
I need to be able to match a particular element in a "row" of a multidimensional array, and then find and reference the other elements in that "row".
Below is a sample of the whole array...
Code:

new Array("Sydney Automobiles - Online","Sydney_Automobiles_Online","users",60.39,3.02,1.21),
new Array("Sydney Automobiles - Hard

I'm fairly new to javascript. I have a code where I'm trying to generate scrollx1 through scrollx100. I can get the array to work with doc.write and I can get one concat variable to work in the element but when I combine them it doesn't work. Any suggestions as to what I need to add to this code:
var sp=1;
for (sp=1;sp<=100;sp++)
{
var sx = "scrollx";
var sy = "scrolly";

I would like to go to a url based on what the user selects from three seperate pull down menus.
Example user selects a product. Then selects a month and Selects a year.
month and year would join together Then create a path
<a href="product/month_year/DEFAULT.HTM">
I this possible with javascript.
I have interesting question about javascript. I'm no expert but I do understand coding for few languages and html. Let me give an example:
Illinois="";
Alabama="";
besttest[1]="Illinois";
strOut+='
<select>
<option value=illinois' +Illinois+ '>Illinois</option>
<option value=illinois' +Alabama+ '>Alabama</option>
</select>';
Would it be possible to make besttest[1] arrays value an actual variable name and assign it string value "selected"? I have "for" loop that returns the selected state and I need to somehow pass that variable name (which has value "selected") to option tag. And that variable name is the actual value of array.
I want to know if there is a way to return ajax call as html value and not plain text, ie all html formatting will be displayed.
My code:

String returned from webform4.aspx is html formatted but jquery displayed it as plain text. Is that anyway to display it as html string ?
I have a for loop: Code: for( var i = 0; i < aInput.length; i++ ) I want to use this i variable to concatonate it as a string to find an input box
Code:
var j = i;

qualname.toString();
if ( inputName == ( qualname ) )
{
Assuming I have a input box named discountqualifier0, discountqualifier1, discountqualifier2 etc...
I have some jquery code like this:
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=windows-1258" />

I need a simple, quick and efficient way to logically branch if I find a string is contained in another string in jquery Most other languages this can be resolved in one or two lines and it would be readable.
View 5 Replies View RelatedI have a simple example below showing how when I pass in the value of the value attribute of option node, and then use if operator to check whether parameter is a string or not, even though it's a string, it converts it to false boolean and triggers the else statement rather than calling a function.callback should be a string so why is it saying otherwise?

I've noticed that IE apparently has a horrible implementation of the
array object, since traversing one with as few as 1000 items it tends
to pop up a dialog informing the user that the script is taking too
long. I tried splitting the array into a 10x100 two-dimensional array
as well as changing the array to a linked list, but neither improved
the code's efficiency sufficiently. Can anyone suggest methods for
optimizing array efficiency, or some other workaround for yet another
one of Bill Gates' blunders?
I have a web document created by a script and instead of going back to
the db I choose to either create an array to iterate through or xml to
parse through.
So, my question is: What are the trade offs between using an array to
load data from or an xml structure?
My array would look like:
myarray = [[],[],[],[]]
My xml like:
<xml>
<data>
<a></a><b></b>
</data>
</xml>
I would use js to iterate or getElementByTagName to find data. I am thinking the page would load faster using xml, and then the user may not even use that functionality. In all cases I have to load the array to memory.
I am with XHTML and CSS as much do I have to learn in JavaScript programming. I’m just beginning to understand and modify the DOM and I ran into something that I couldn’t find a solution for after some extensive search. I have this function:
if(document.getElementById && document.createElement) {
function addflags() {
var children = document.getElementById('pagelist').childNodes;
for(var i = 0; i < children.length; i++) {
children[0].className = 'bulgaria'
children[1].className = 'england'
children[2].className = 'italy'
children[3].className = 'sweden'
}
}
window.
}
The XHTML is an unordered list with 4 list items and sub lists in those list items (plus links in each li) and I want to add a country flag (set as background image in the CSS) to the direct children of the ul (the first level list items).
Now I discovered that Firefox is only reacting to odd array numbers, i.e. children[1], 3, 5, and 7 (the even numbers have "no properties") while IE is applying the classes correctly(?) as intended above (0,1,2,3).
At which point did I go wrong? Sorry if this is a real stupid question but I’m pretty new in this field and my researches didn’t bring any acceptable results.
Is what I'm doing the right approach to creating an array of arrays? I have an external datafile with several employees' records. They are stored in an array with each element of the array being the complete employee record, ie: name, date of hire, etc., etc. These attributes are delimited by a :. I'm trying to separate these attributes while keeping the original array intact. That way I can access these attributes and validate whether or not an instance of the employee object will occur. There are too many records to create this from the start, so I'm trying to implement a for loop to do it for me. This is what I tried: datafile is the name of the original array of employees. emp is the array I'm trying to create .
for(var i=0;i<datafile.length;i++){
var emp = datafile[i].split(":");
//document.writeln(emp.length+"<br>");
/document.writeln(datafile[i]+"<br>");
}
//document.writeln(datafile[0]+"<br>");
How do I set this to "disabled":
<select name="awards[]" multiple size="6">
<option value="1">Award 1</option>
<option value="2">Award 2</option>
<option value="3">Award 3</option>
<option value="4">Award 4</option>
</select>
I don't know how many options there will be as they are fed from a DB.
Anybody got any suggestions about using two arrays. First i need to
ask the user their name and if their require a seat between 1and 5 or
between 6 and 10. I need to assign this information in two arrays.
Any suggestions. I have been working on this so far.
<script type="text/javascript">
var theArray = new Array(10);
//var sizeOfArray = parseInt(prompt("How many items will the array
have?", ""));
for(i=0; i<10; i++)
{
theArray[i] = prompt( "Please enter your name");
}
for(i=0; i<theArray.length; i++)
{
document.writeln( "theArray[" + i + " ] = " + theArray[i] + "<br />");
}
</script>
I want to make algorithms that take selections from arrays and put them together in new ways. here is a simple array I set up for notes of a piano keyboard: Code:
View 4 Replies View RelatedSafari 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?
Any neat way to copy a snapshot of one array to another?
A normal assignment results in the second array pointing to the first,
with changes to either array affecting both.
As a trivial example:
var a=new Array();
a[0]="zero";
var b=a;
b[1]="one";
alert("a="+a.join("*")+String.fromCharCode(10)+"b="+b.join("*"));
.... this results in a and b being identical two-element arrays.
Is there any easy way to set array (b) to be a copy of (a) BY VALUE -
ie using the contents of (a) as they were at the moment of assignment,
but leaving the two arrays separate so that subsequent changes to one
array does not affect the other?
