View 3 RepliesI want to call a function inside a loop of an array but when I run it, it is only reaching the function the first time.
for (i in qMedia) {
writeMedia(qMedia[i].name, qMedia[i].format);
}
Even when I tried to call it outside the loop multiple times, it only executed once.
writeMedia(qMedia[0].name, qMedia[0].format);
writeMedia(qMedia[1].name, qMedia[1].format);
writeMedia(qMedia[2].name, qMedia[2].format);
I know that each of the objects in the array have data because I tried to run each one of the lines above separately without calling the other two and it worked fine.
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.
<button onClick="return popup('<span onClick='selectShape(1, 1, 1)'>test<span>');" tabindex=Ɖ' onFocus="setFocusColor(0,3)">....</button>
This will work perfectly, but as soon as I need to pass Strings inside the selectShape function, I get stuck.
So the question is, how can I create the following and have it working
......selectShape(2, 'Tricky', ཤx5°').....
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 have a simple HTML page with one DIV element with the id "rotator". Inside that, JavaScript is supposed to create boxes that react to mouseovers.
The weird thing is: The whole script works, but ONLY on the LAST box I create, no matter what I do. I can manually add the mouseover code to any one of these boxes, but it will only take on the last one. I can have JavaScript tell me the mouseover status of each box, and they all tell me they have code assigned correctly - but again only the last one works...
Here's the relevant code (yes, highly abbreviated, but it's the part that fails on me):
var maxBoxes = 10;
function initSite() {
var rotator = document.getElementById("rotator");
rotator.innerHTML = "";
[Code]....
initSite is called in the body onload. All kinds of other animation parts are implemented that work fine, just this mouseover won't work. I have tried re-writing it in multiple different ways, including "xyz.onmouseover = myMouseCode" and then defining the function separately later - still no dice.
So, the code creates 10 boxes (0-9) and 10 boxes that are on top of them to create a form of shadow effect depending on the position of the original boxes. Since the "myDark" boxes are on top of the "myBox" boxes, I apply the onmouseover onto the "myDark" boxes, but it only works on "myDark9" and no other box. They are all created the same way, the mouseover assigned the same way...

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);
});
I am trying to piece together a bit of form validation. I can not get the two scripts to work together via onsubmit. CardVal works onclick and DataVal works onsubmit.
1. first i tried to call the CheckCardNumber(this.form) from inside the DataValidation.js after it returned true. Is that even possible? I could not figure it out...
2. i tried inserting this into the <form> tag:
(subform_validator(this) && CheckCardNumber(this.form));"
is that even possible? my javascript skills are not exactly expert so forgive me if i have overlooked something extremely simple... Code:
I have an html input and when a button is clicked, that input's value is passed to a function. However, the value becomes undefined when execution gets inside the function despite NOT being undefined inside the event handler! See below code...

1.In ZZZ.html i have a long list of text items formated like this:
<div="part1">
<span > <h3 >AAA</h3><h4>BBB</h4></span>
<span > <h3 >CCC</h3><h4>DDD</h4></span>

In another document i made some buttons to change slideshow content by loading sections id to
<div id="cyc" class="slide"></div>
using function:
$('#cyc').load("ZZZ.html #part1");
etc...
Text loaded, but the slideshow didn`t work
2.How can i loop specific range of slides ( and make it modifiable with some "range selector" in browser) ?
3.Is it possible to trigger some event on the desired slide number ?for example:
on slide 3 - play sound
on slide 6 - display message
on slide 15 - go through slides 10-15 four times

View 2 Replies View RelatedI am using jquery for getting ajax responses from server side functions.
I am in a situation where I need to make two ajax calls one after another and the second one is dependent on the response of the first one.
I have tried to use a code which is similar to this one?

type: 'GET',
url: 'myURL',
success: function(data)

Is it possible to get two have two ajax calls , one dependent on the other?
I'm using jquery to make it easy for AJAX calls.
So I create a class: function cMap(mapID){//vars and stuff}
I go and prototype a function: cMap.prototype.loadMap = function(){ //jquery AJAX call }
Now in the jquery $.ajax({...}); call, I use an anonymous function on the "success:" call: success: function(data){ this.member = data; }
My problem is that inside this anonymous function call I'm trying to call a class member of my cMap class to store the data in from the AJAX call, but it's out of scope. So the JS console in FF/Chrome throws errors about bad value/doesn't exist.
How can I access this class member from inside an anonymous function? Or at least what's a good way to go about doing all this?
I have been looking at this code for two evenings now, and rewrote it 4 times already. It started out as jQuery code and now it's just concatenating strings together.
What I'm trying to do: Build a menu/outline using unordered lists from a multidimensional array.
What is happening: Inside the buildMenuHTML function, if I call buildMenuHTML, the for loop only happens once (i.e. only for 'i' having a value of '0'.) If I comment out the call to itself, it goes through the for loop all 3 times, but obviously the submenus are not created.
Here is the test object:
test = [
{
"name" : "Menu 1",
"url" : "menu1.html",
"submenu" : [
[Code].....
'Menu 2' and 'Menu 3' don't show up! I'm sure it's something small that I'm overlooking.
I am trying to use a for loop to call images of custom text. For example, I have images named uppera.png and lowera.png for a custom font. I need the image of the letter to show up as they type into a text area, but also have backspace work correctly to delete the last image added. Here is the code I have thus far:
<script type="text/javascript">
function callimage() {
var chars = document.getElementById('userinput').value.split("");[code]....
When I test this out it takes the previously entered text and adds it to the new text and combines them. For instance if you entered "a" it would show up as "a"; if you entered "a" again it would show up as "aaa" and then "aaaaaa" and so on. Also, it will add the existing characters again if any key is pressed, like just shift. I think I would need to write an else statement to fix that part, but I don't know what to put there, either.
I'm currently trying to produce an HTML table from an XML feed, using jQuery. And this works great! With an "each" loop, there now is a nice table on my screen, displaying the right information from the feed.
I would like for each new row of this table to have a separate color. For example:
row 1 - blue
row 2 - green
row 3 - blue again
row 4 - green again
...
and so on...
What I've tried, is putting something like this inside the loop:
var
x=0
(this line should probably be outside of the loop, but that doesn't seem to work)
if
(x=0)
code 1...
x=x+1
else
code 2...
x=x-1
But this doesn't work.
I have this loop:
for (var j = 0; j < gmarkers.length; j++) {
gmarkers[j].hide();
elabels[j].hide();
map.closeInfoWindow();

which was useful for passing the p variable when it was just one number.
but now I need to get that number every time j gets set (I understand that the j gets overwritten each time the loop goes through).
What would be ideal is if p could become an array, the contents of which match the values that j has passed though during the loop cycle.
I thought var p = new Array (j); minght do the trick, but obviously not...
I have a theoretical question, I can't really post my code. But I have four results from reads to a database using php. I then read from an xml file using javascript using a loop. I am basically creating a chart of four variables with several different values for each variable. Some of the values for each variables come from the database using php, and some come straight off the XML file parsing done by the javascript. I initially had the php fetch/extract inside of the javascript loop, but it only assigned the first variables values to all the other variables. I discovered (after hours of googling) the difference between client side and server side code. So, after all this typing, my question is where should I look for tutorials on using Ajax to be able to use php code inside of a javascript loop? (If at all possible)
View 2 Replies View RelatedI've always wonder if there is diference when declaring and
initializing a varible inside/outside a loop.
What's a better practice?
Declaring and initializing variables inside a loop routine, like this:
for(var i=0; i<list; i++)
{
var name = list[i];
}
or outside a loop routine, like this:
var i;
var name;
for (i=0; i<list; i++)
{
name = list[i];
}
or are both the same....

View 1 Replies View RelatedI am trying to understand the order of operations of a for loop.
for (count=1;count<3;++count)
{
document.write(count + ". nice rack.")
}
when this runs it prints:
1. nice rack.
2. nice rack.
I dont understand how it prints 1. The way I see it it sees the for looks inside the parenthesis, assigns count a value of 1, goes to the comparison sees that it is less than 3, then gets incremented by 1 at the next station, and then finally goes in the curly brackets and the string is written. So if it starts with 1, is less than 3, and is increased by 1. before it starts the loop, then the first sentence would read:
I am calling a program using $.getJSON() inside of a for loop. The problem is that the second callback doesn't wait for the first program to finish before it executes. Is it possible to ensure that the second iteration of the loop doesn't happen until the first one is finished?
