JQuery :: Get Values From A Select Menu Then Assign Them To An Array Variable?
Sep 7, 2009I have a menu like this:
[Code]...
I have a menu like this:
[Code]...
I'm having problems with selecting values from array.I have a dropdown box where you choose what fruit you want to buy.When selected the array should assign 2 values to that fruit.Here's what I have.. I added comments.
Javascript part:
<script type="text/javascript">
function Fruits() {
var selectfruit = newArray( //assigning values to fruit selected from dropdown box
newArray("Banana", 1, 1),
[code]....
If I assign an array to another variable, any changes to the array change both variables. Is it a pointer instead of a copy? Try this:
<script type="text/javascript">
Arr=['a','b','c'];
Arr2=Arr;
[code]....
Variables don't do this but it's happening for arrays in IE and FireFox, maybe all others.
I would like to create dynamic variable name and assign values to them.
Something like this:
I want to create these names dynamically.
I tried: var item{i} where i is the dynamic variable.
Nothing seems to be working.
I also tried:
It doesnt recognize : var eval('item'+i)
This one is throwing me off! Either I am making a stupid mistake or I'm doing it totally wrong I have an array, and I am trying to select unique values from it and assign it to another array. Here is the code:
Code:
var flag;
for (i=0;i<=pdfs.length-1;i++)
{
flag = 1;
for (j=0;j<=pdfs2.length-1;j++)
[Code]...
The problem is that the if (pdfs2[j] == pdfs[i]) statement ends up never being true. There are URL's to pdf files in the array. On the other side, if there is a much easier way to select unique values from an array, please feel free to point it out.
I have searched the web and this forumn with no results. I need to replace the value in a second select menu with the value from the firts select menu. So if I select ACD from the first menu it should go thru all the option values in menu 2 and replace the '~' with 'Computing'
[Code]...
I have a select array like this ..
Code:
<SELECT NAME="state[]" MULTIPLE size="10" onchange="content();">
<OPTION VALUE="abc">abc</OPTION>
<OPTION VALUE="zyxc">zyxc</OPTION>
[code]....
So I created a javascript to get all the selected values in one variable ... But whtever I try the values don't come .. I tried alerting at different places and wht I see is tht it don't even go into the for loop ...
Code:
<SCRIPT>
function content() {
var retval = new Array();
for(i = 0; i < document.form100.state.length; i++)
[Code]...
It is kind of difficult to explain what I am trying to do here, I will provide the form here to give a better idea.
<ul>
<li>Select the type of your starting point of interest:<br/>
<div id="start_menu"><form action="test_getrss.php" name="form1" method="post">
<span><input type="radio" value="Apartment" name="start"
[Code]....
I get values for start_time, end_time and semester, but not the last two values. I noticed that the first two forms here are dynamically generated from Ajax.
How can I pass the values of these two selected menus to the third form, to process.php so the values can be retrieved?
i'm trying to build a small script for predicting Worldcup football winners. participants have to predict the teams in both the semi finals and final. a select menu with all participating countries will be given for 2 semi finals. suppose if a persons selects Argentina and Brazil for Semi 1, then the values of Final select menu should be Argentina and Brazil. Similarly for Semi 2, if Denmark and Italy selected, then the select menu for final2 should be Denmark and Italy.
my html (with only a few no. of countries is below:
[CODE]
<b>Semi Final 1:</b><select id="semi11" class="select menufield_101" name="semi11" onchange="ChangeValue(this);">
<option value="empty">Select a SemiFinalist</option>
<option value="Algeria">Algeria</option>

I'm trying to assign IPAddress to using the code below:
function GetIP() {
$.getJSON("http://jsonip.appspot.com?callback=?",function(ipadd){
//var IPAddr;
[code].....
I am developing a jQuery application and I need to get a parameter from one getJSON request, then use it in another.
Here's a code example that of course is not working:
var ipAddr;
jQuery(function() {
// request IP address
$.getJSON("http://jsonip.appspot.com?callback=?", function(data) {
[Code].....
I know that getting IP address is very easy using PHP or other server side scripting language but I am bound on using HTML and jQuery only.
I want to assign value to global variable in javascript from jquery ajax function.
Here i need the value of trueFalse from success function.
I have to following piece of code:
var myarray = new Array();
$.ajax({
url: 'http://distantserver.net/path/script',
dataType: "jsonp",
data: {
[Code]...
It's a cross-domain request. The first console.log() debug message prints the desired result, the second doesn't. It seems that the variable myarray has its scope limited to the success-callback. How do I get the data out of the success-callback?
I have kind of a complicated setup, and I was hoping to bounce this off some one's head who's more experienced with JavaScript.Assuming I have the following HTML markup:
<div id="one-root">
ONE
<div id="one">
[code]....
var html = $.get('templates/Template.html', function(html) {
});
console.log(html);
The object returned, html, have the property response, wich contain the html of page Template.html In firebug I see that the property responseText have all the html of the page, but... how can I get this value? I have try with:

I want to assign values to a combobox .On click I want to set the values as 1 else set to 0. The combo box is in an array.
View 4 Replies View RelatedI'm trying to learn JavaScript on my own and am using a Dashcode example (if anybody uses Dashcode, the example is the "Browser" web application template that is shown when Dashcode opens).
Briefly, the JavaScript generates a list of "Locations" in the USA:
Code JavaScript:
// Sample data. Some applications may have static data like this, but most will want to use information fetched remotely via XMLHttpRequest.
var parks = [
[Code]....
I want to retain the layout and structure but, depending on the "Location" have different text for each of the new pages (not "the scenery is amazing etc).
I have a form where attachments can be added. Those attachment values will be wrapped into html code so it will be links. As they can click on a + sign to add more input fields, the amount of input fields is dynamic.
For each input tag there is, this value will be written to a hidden form field called "url" before it will be sent to the database.
Now it works and adds data to the database... but not for every form field apparently. Only for 1 new field..

I was wondering if it were possible to assign a PHP variable's value to that of a JS variable. What I mean is having a var in JS, and then making a PHP variable equal to the JS one.
Like this code...
Now of course, this file will be .php, and will be called as such when including it to a page (<script type="text/javascript" src="username.php").
The above code doesn't work... But I want to know if it can be done in such a manner. I just want a PHP variable to be equal to a variable in JS.
How can I assign a link with its related elements (as following) to an array element?
Assume having a table with several rows and 3 columns. The first column holding some text information (which will be read from a database) but the 2nd column holding a link (as its previous rows - now I'm adding a new row).
Since I'm adding records or rows to this table I need to provide the link in the 2nd column and the worst thing thing, this is my first PHP project!
Any advice?
<span id="button_<?=$item?>_edit"><a href="javascript:edit('<?=
$item?>', 1, '<?=$max?>');
javascript:MyFunc(document.getElementById('iptext_ <?=$item?>'));"
I'm Stephen Martin, an undergraduate Psychology student and researcher. Although I am a self-proclaimed tech geek, the extent of my knowledge ends abruptly at any sort of coding. The paradigm: I am currently investigating the decision making strategies in a particular population (I cannot reveal too much, lest our study be scooped by competing researchers in the field). The paradigm that we use is built through a package called MouseLabWeb [URL]. MLWeb basically provides an interface for researchers to create a html/php/js/css website that presents a grid (table). A small example is shown on the aforementioned website. The javascript functions allow each participant's events to be recorded, timestamped, and written to a MySQL database. This allows the researcher to know which cells the participant viewed, in what order, for how long, and ultimately to which decision the participant came.
Additionally, the PHP/HTML creates the table, but the data within it is populated by the javascript. This is a blessing and a curse. Here is why. The problem: The javascript offered by MLWeb allows the cells to be randomized. This is necessary, because in such paradigms, counter-balancing is required, otherwise there would be order effects (e.g., people tend to automatically read from the upper left) that are not controlled for. So the order of the columns and rows are randomized, the data which is then placed into the html/php table.
For the current study, we want the cells corresponding to particular types of information to be shaded differently. For example, we'd want cells that contain bad information to be dark, cells that contain neutral info to be grey, and cells that contain good information to be white. The problem is that setting these values (style="background-color: #XXXXX) only applies to the table as created by the PHP. It only affects the position, and does not consider the information that it is filled with.

I have a number of input boxes used to display totals based on
selected items for each row in a table. There are more than a few
rows that are identical, except for the form field name. I have added
a sample of that below (there would be many more rows).
I'm wondering if there is a way to dynamically generate the variable
names (ie: T1val, T2val, etc.) in my function 'calc', based on the
argument 'regnum' that I pass it. The problem right now, is that I
have to repeat lines 9 to 15 for every row that I add, using the
specific variable names for each. If there was some way to
dynamically create and assign them using the value of 'regnum'
(similar to using 'elements'), that would be great.
I guess one way might be to create hidden fields for each of those
variables, and I could then use the 'elements' syntax to assign
values, but wondered if there is a simpler way. Code:
Basically what I am doing is reading some values from a javascript that reads from an XML file. What I am trying to accomplish is a way to assign a variable that was declared within the "<% .. String strValue="" .... %>" section of my JSP page with a value returned from the script. Here is my code:
<HTML>
<BODY>
<%
String strValue = "NONE";
%>
......
<SCRIPT type="text/javascript">
xmlDoc=loadXMLDoc("customers.xml");
var x=xmlDoc.getElementsByTagName('name');
document.write(x[2].childNodes[0].nodeValue);
</SCRIPT>
</BODY>
</HTML>
As you can see in the above code the output of the script will be the 3rd node(starting from 0 to 2). I would like to assign the output of "x[2].childNodes[0].nodeValue" to the variable that was declared in the beginning "strValue".
I have tried different combinations but since the variable needs to be encapsulated with the "<% %>" notation because of JSP, I am stumped.
I have a variable in a js slideshow as follows :
source:[URL]
I have a form set up in which the end-user enters in the 'alexr2012' (form variable = sname) How do I change out the alexr2012 to sname so that the Data value is not hard coded ? that is - the data value is determine by the end-user entry ?
I have several lines of code in different functions where I need to refer to elements in document.form.max, so I figured I would define it as a global variable called tb1 to shorten the writing. The result however is the page senses an error as soon as it gets to tb1.value, of which I can't figure out why since things work when I change tb1 into a local variable. I was under the impression that global = full scope, so I'm not sure what's wrong here.[code]...
View 12 Replies View RelatedLooking for a little bit of help. I created a simple script a while back in PHP which reads all the images from a directory and assigns them to an array (reading for loading into a document). Would I be able to do this in JavaScript or does it not have these kind of privileges?
