JQuery :: Update Variable In Html From Within A For Loop
May 22, 2011
So i have this code
[Code]...
and what i want to happen is the variable number to update so that the user can see how many times the loop has run in real time. If you have to change the code around for it to work that is fine as i can adapt my code to it And obviously this script has no real function to it, it is just an example to show the jist of my actual code(don't think you want to look at a few hundred lines now do you)

I want to update the contents of several divs periodically with the response i get from a php-script. the number of divs is changing depending on what the user has chosen before. i store the variable part of the ids in a hidden input field. this input field may look like this:
<input type="hidden" name="devices" value="1,2,3,4,5,6,7">
to do this task periodically i use setIntervall():
<script type="text/javascript">
// dies stellt sicher, dass updateDivs() erst ausgeführt wird, wenn

I'm looking to send a loop variable (i) to a function inside the loop, but I can't seem to get it to use the value I want, it keeps making it a reference of i and therefore the function is always called using the last value of i rather than the one it was set with.
So if i have 5 Tabs then Tab 1, when clicked, should call DefaultTabClick(0) and so on rather than always using 4 for any of the tabs.

I have an ASP.NET MVC web application, consisting of subcontrollers, each generating their specific html contained by divs.
As an example, on the same page this is generated (among other stuff):
<div id="trace"/>
and
<div id="survey">
textfields and ajax submit button
</div>
Now, the survey has a submit button in a Ajax.BeginForm, that does a partial update of the durvey div itself.
What I also want to do, is that if the submit button is clicked, not only the partial update occurs of the survey div, but I also want to get other partial data and display that in the trace div which is also on the page somewhere.
I tried to execute some jquery after the partial update, but apparently that code is not executed.

I was wondering if someone could help me out with the following.I'm developing a webshop CMS in which you can create categories. By using jquery's ajax method I'm making a POST request to a PHP script which then handles all the data supplied to it. This works good and all except for the fact that after the query is being executed my HTML doesn't get updated, at least not as well as I want it to.I understand that the common way of working here is to update HTML in the success callback of the ajax method. But the thing is that every category is being displayed as a list item with an id attribute, this id corresponds to the id the category has in the database.If$.ajax tells me that everything went down smoothly and my query has been executed then there's still no way for me to know which id this new category has been given so that I can update the HTML accordingly.
What would be a "smart" way to tackle this? The first thing that comes to my mind is simply calling another script which figures out the last inserted id on the db but that would mean doing an ajax request in the callback of another ajax request? That doesn't sound right to me..

I have a html file that I want to load, loop through the json data and for each json entry I want to add a new block of the html and insert the json data into the matching div/class of the html. json looks like this:
{"Super" : [{"Name" : "John Doe", "Age" : "30"}, {"Name" : "Jane Doe", "Age" : "40"}]};
html looks like this:
<div class="Name"></div><div class="Age"></div>
So for each json entry of name/age, I want to insert that into the html, and then add another row, until all json data has been fetched. After this I want to insert all of this into #box, which is just a divthat should contain that html. Looping like this obviously does not work, since I just keep replacing the same html through the loop.
var jsonData = {"Super" : [{"Name" : "John Doe", "Age" : "30"}, {"Name" : "Jane Doe", "Age" : "40"}]};
$.each(json.Super, function() {
$('#box .Name').html(this.Name);
$('#box .Age).html(this.Age);
});

I'm having some problem with return value for a function. I'm trying to access google blogger's API to display blog entries on my site. I'm doing this through JQuery and requesting a JSON response. Everything seems to work ok, but I want to access the link for the blog entry. This is a subset of the "entry" object.
It's structured like this:
Entry:
title,
content,
link:
rel,
type,
href,
rel,
type,
href,
I want to get the link where the "link.rel == "self". To do this I have to loop through the link object (5 times). The loop and conditional statement works correctly, but I can't get the variable inside this loop back to my original function.
I have this code:
$.each(data.feed.entry, function(i, entry){
$.each(entry.link, function(j, link){
if(link.rel == "self"){
var postlink = link.href;
alert("link : " + postlink);
return postlink;
}});
alert(postlink);
});

so, the pseudo code: - on change of input contents, check to see if two input fields are set - if set, update a third field with "loading..." text and a loading gif - use ajax to send data to a url, and get a calculated json response - update the third field with the calculated response
I know I'm getting the correct response, according to firebug: {"pace":"10:00"}
the code:
$('#run_distance').change(function() {
if ($(this).val() != '' && $('#run_time').val() != '')
{
$('#run_pace').val('Calculating Pace…');
[Code].....
how to update the #run_pace input field with the json response.

I want to load an html div in a variable, modify it in another variable; and then change the document injecting the contents.
1. I load the html to be changed in a variable (code)
2. I modify an attribute of <param> using attr() and I put the result in a var (newcode)
3. I change the html in the doc
I've used the debugger, and all steps give the expected results, except of newcode.html(), which is a null string. Why?

The following PHP code populates a dropdown list of Projects. I would like to be able to click on a Project Name in the list and have its corresponding list of Characters appear beside it. How can I tie jquery into this as it's running? All the jquery examples I see are for hard coded HTML data instead of a PHP loop grabbing from a database.
Code:
//creates the Project dropdown list
while ($proj = mysql_fetch_array($project)){
$id_proj = $proj['projid'];
$name_proj = htmlspecialchars($proj['projectName']);
[Code]....
I don't care if it's a clickable list of anchors instead of a dropdown. Also, I don't care whether people have javascript enabled as this is for my personal use.

I have this problem that is really bugging me. I am trying to implement this script found in Javascriptkit: [URL]
It has a very unique feature of grabbing arbitrary HTML tags and attaching tooltips to them. Priceless to my site. But the problem is, the script only works with jQuery up to 1.2.6... after that version, it stops working entirely. Quite an issue, as you can imagine. It also has some issues with browsers other than Firefox that I hope updating the code might fix.

I'm working on a project which requires a small portion from a large table of information to be displayed on a webpage (sort of like a magnifying glass). The display will be a table of fixed size (m by n cells). Some of the cells will be merged. When the table updates, different sets of cells may be merged.
It needs to be coded in HTML5, which I assume includes the use of JavaScript and CSS (The specs of this is rather unclear at the moment, so I'm going to cover all bases).
Anyhow, looking through the HTML5 and JavaScript tutorials, I found two ways to solve this problem. One way would be to have a script to parse out the relevant information, and have it output into a table (dynamically generating the HTML required).
The second way would be to have the script draw the table on its own in a canvas.
User events (such as arrow keys on the keyboard) will change the position of the focus (move the magnifying glass in a cardinal direction).
I hit a small snag with the first solution - Is it possible to update the table on the page (including changing the structure of it) without having to refresh?

I'm trying to make it so when you click a cell in a table it runs a function based on the value within that cell. With the current code, no matter what cell is clicked, the alert box displays the same number, which is the last number in my array. The variable, princ, is just being overwritten rather than writing code to each the cell with the proper value.
for(i=0;i<=3;i++){
document.writeln('<tr>');
document.writeln('<th>'+(periodArray[i])+'</th>');

The following loop works:
Code:
<html>
<body>
<script type="text/javascript">
var i=0;
for (i=0;i<=5;i++) {
document.write("The number is " + i);
document.write("<br />");
}
</script>
</body>
</html>
But the following doesn't:
Code:
<html>
<body>
<script type="text/javascript">
var i=0;
var x="i=0;i<=5;i++"
for (x){
document.write("The number is " + i);
document.write("<br />");
}
</script>
</body>
</html>
I'd just like to create a simple variable.

i'm having trouble with some of my codes.i've been trying to put variables in function calls parameters, but it just does not work.
for example, if I try to do sth like this:
Code:
//a function that creates page numbers based on number of pictures that can be shown on the page
function MenuBar() {
pageSpan = [document.createElement('span')];[code]....
when i try to run it, it won't work.what i'm trying to do is that every time the loop runs, the "onclick" event of the created span will be the value of the loops "x" variable -1, and the value of x variable.meaning, for every new span, the parameters in the showImage() function are different.
Code:
pageSpan[1].onclick = function () { showImages(0, 1) };
pageSpan[2].onclick = function () { showImages(1, 2) };
pageSpan[3].onclick = function () { showImages(2, 3) };
pageSpan[4].onclick = function () { showImages(3, 4) };
pageSpan[5].onclick = function () { showImages(4, 5) };

I am working on a project where I need to redo the same thing with new variable names
Code JavaScript:
var paper1 = new Raphael('img1', 500, 500);
c1 = paper1.rect(0, 0, 50, 20, 5);
var paper2 = new Raphael('img2', 500, 500);
c2 = paper2.rect(0, 0, 50, 20, 5);
I would like to be able to do this with a for loop. So in the above example I would want paper+i, img+i, and c+i was trying eval("paper"+i) but didn't work.

All I need to do is; on the click of a button, import the numerical
data in an html form (only one field) to a cell in a spreadsheet. Both
spreadsheet and the html file reside on the same server but there are
no dynamic capabilities. All I can use is html pages + javascript (or
anything else which do not require any special programs to be installed
on the server). Is this at all possible?

I am trying to create a simple HTML table with the squares of numbers and for some reason the loop is not triggering.
Code:
<table border="1">
<tr><td><h2>Table of Squares</h2></td></tr>
<tr><td>
Number
[Code]....
When I run the page all that comes up is the start of the table that is written before the script executes. Also is there any way I could use a debugger to catch this on my own? I tried the firefox debugger but it didn't catch anything when I ran it through, maybe I was just doing it wrong.

I'm trying to create a function which shows a hidden response when a button is clicked on.I also want to add the response to a variable which lists all the users responses.Here is my code now...
$(".yes").click(function () {var feedback = feedback + $(this).html();
$(this).parent().next("p").show("fast"); });
$(".no").click(function () { $(this).parent().next("p").next("p").show("fast"); });
$("#email").click(function () { alert(feedback) });
The bolded line is the part which isn't working.
