I have some input fields of type text. I have two arrays, one containing values and second containing the value of "name" attributes. Now I want to use them in my php script on the SAME PAGE.
View 6 RepliesI am working on a simple Expanding Family Tree.
There are two principal Objects: Person and Family,
and two subsidiary ones: Sibling-sets and multi-Marriage-sets.
When I click on a Family Button, I want to display all the Persons
of a Sibling-set.
Married Siblings will have a Button. Pressing this should display
one or more Marriage-Partners. If these Marriages (Families)
have children, they will have a Family-Button.
You will notice the code for the four objects is fairly repetitious,
but that for the variable-length Sibling and Marriage Arrays,
is what has kept me struggling for days.
Lines S04-S10 and M04-M10 appear to be the problems.
Even though I think addSibling() is constructing Sibling objects,
S06 reads the Argument vector as a single item
S07 tells me the argument-count is 1.
so S09 processes only once, and then..
it interprets argv[s] as a single item,
but assigns the whole array to this.sibA.
Can anyone tell me what I am doing wrong? Code:
However, there is one problem that I just can not figure out. I have 3 arrays storing information on page1.htm, this is all well and good, but I want to use the data stored in those 3 arrays when the user moves to page2.htm.

may be more qualified to help me find a solution.
In short: is it possible to call a Java method from JavaScript, passing
as an argument a JavaScript array (in my case, an array of doubles)?
Supposing I have array x containing only doubles, I have tried:
document.MyApplet.myMethod(x);
But the method only ever seems to receive "null" as an argument.
Conversely, if I try this with a String, or a single character, or
almost anything else, there isn't a problem. Any ideas?
I was having some trouble with 2D arrays (or array of arrays). Essentially, the array has 100 rows, with two columns. The first column of every row holds a name, and the second holds a sales amount. With the use of a do while loop, the user can continuously add up to 100 names and sales amounts. After all the information the user wishes to add is stored into the 2D array I'm attempting to pass that very same 2D array as a parameter to a function called printRow as can be seen in the code below: Note: the function call and the actual function are found in two separate javascripts.

I want to know how to account elements and arrays. the elements I want to count based on their value. how many there are. and then for the array I just want to count how many there are in a html array.
how could I count these? then how can I select the elements name that matches those values?
how would one post a multidimensional array to a php script. The ajax section on here in the docs... only show how you would pass just one array. I need to pass a multidimensional arrays to my php scripts.
View 2 Replies View RelatedI have a list of inputs
<div id="divID">
<input title="foo" type="text">
<input title="bar" type="text">
</div>
Then I'm trying to use jQuery to cycle through each input and ascribe ".attr("value") to each respective <input>. So far I've been using something along these lines:
var input = $('#divID input')
input.each(function(i) {
var title = input[i].attr("title");
input[i].attr("value", title);
}
If I remove the "[i]", it fills in every box with the title of the first <input>. If I leave it there, it fills in the first input, and then upon looping, says input[i].attr is not a function. So, if I type console.log(input[1]), firebug returns the correct <input> tag, but as soon as I add the .attr(); function, it blows up.
Here how i did it:
var Inputs =$.merge(reqChecks, reqFields);
var allInputs =$.merge(reqSels,Inputs);
Is there a more elegant way to do that ?
I have two arrays and text variable.I need find all substrings from first array and replace them with corresponding substrings from second array in this variable.In php it would be$text = str_replace ($array1, $array2, $text);I know it is more complicated in javascript, and i have little experience in it.

Please help. This kind of thing is driving me nuts. I hate working with primitive stuff and having to do a lot of redundancy just to get data transmitted. I just want it to work with the domain object model on the server... but there's always these weird exceptions that make that impossible. It's amazing that in 2010, we are still working in basic numbers and arrays and having to take apart and put together data at a primitive level.
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.
I am really hoping someone is willing to take the time to read this post and take a minute to take a look at my code. What is happening is there are some matches for a script I made and then an area for segments during an event. If you notice on the segment part of the form is that there is a dropdown that asks for where in the event that segment needs to go. With the Introduction or the different numbered matches. What I need to happen for a subArray I need it to take the introduction, all the matches, and all the segments and order them accordingly. With the introduction first, the matches in order based off there match number and then the segments in between the introduction or matches based off the user's input.

I'm passing the variables myTitle and myLink to form.php using javascript.
This is the way I'm doing it:
Code:
<a href='form.php?title=" + myTitle +"&link="+myLink+">Click me</a>
It's working great but sometimes myTitle and myLink contain the plus character (+). When this happens it's not passed. In the case of the title, it's just a problem of looks but in the case of the link, well, the link won't work without the character.
As an example if the title is: Laptop + Accessories What is passed is: Laptop Accessories
What can I do to pass also the plus character??
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":

<option value="4">Award 4</option>

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?
