I'm having trouble calling a function using a variable, from within a parent function. For instance:
function parent(){
function child(){
console.log("It worked")[code]....
That results in "TypeError: 'undefined' is not a function (evaluating 'window[test]()')"
The code is below but basically I have two global variables, then I have a function and then a function within that, I am simply trying to update these global variables from within the nested function so i can then go on and use them in another function! this sounds like quite a straight forward request to me, but maybe it can not be done? When I do an alert on the variables (after I have apparently updated their values) I get 'undefined'!
Code JavaScript:
var resultLatB;
var resultLngB;
function getLatLngFromTown(town, callbackFunction) {
var localSearchB = new GlocalSearch();
localSearchB.setSearchCompleteCallback(null,
function() {
if (localSearchB.results[0]){
resultLatB = localSearchB.results[0].lat;
resultLngB = localSearchB.results[0].lng;
pointA = resultLatB;
pointB = resultLngB;
//THIS WORKS
alert("Test 1 = " + resultLatB);
alert("Test 1 = " + resultLngB);
}});
localSearchB.execute(town + ", UK");
//DOESN'T WORK... SHOULD IT?
alert("Test 2 = " + resultLatB);
alert("Test 2 = " + resultLngB);
}
getLatLngFromTown("oxfordshire",null);
//I WANT THIS TO WORK!
alert("Test 3 = " + resultLatB);
alert("Test 3 = " + resultLngB);
I have a function which has a nested function in it. I need some variables in the first function to be available in the nested function. How am I supposed to declare a global variable in jquery?
View 4 Replies View RelatedI am attempting to use the return value from a nested ajax function as the value for a variable in its parent. However, despite being able to successfully assign the variable within the nested function, it reverts back to its original value after the child function has terminated. Below is the code:

how can I call a function by using the value of a variable name?i.e.

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 simply trying to use a global variable in javascript, but can only access the variable on the second call. I can't find anything that relates to this through my searches. My application is supposed to query the server for XML that tells me which years and months are available to put into combo boxes. I want to store this xml in a global variable to access it later.
[Code]....
<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°').....
function foo () {
var xyz = 123;
function bar () {
var abc = 456;
}
}
I can alert (foo) to see the function source
Is there an alert (<something>) that will show me only the source of
function bar inside function foo ?
Cycle will handle variable timeouts, and it will handle nested slideshows, but I can't find any code for variable timeouts within nested slideshows. I've tried cobbling together a fix, but it didn't work (don't ask me to explain...it's embarrassing).
how to mate the script for variable timeouts with the code for nested slideshows?
I am trying to declare a variable inside a function and use it later on in my code... but it just already returns white space... i.e. not variable value. I am setting it within this function:
function show_video1(){
document.getElementById('video1').style.display="block";
var video1Name = "Education World News (Part 1)";
document.getElementById('video2').style.display="none";
document.getElementById('video3').style.display="none";
document.getElementById('video4').style.display="none";
[Code]...
and trying to call it later on with this: <script type="text/javascript">document.write(video1Name)</script> It might be worth noting that each one of my 11 videos will hace a different name.
I am trying to reference a session variable inside some JQuery code. Theseexamples below arewhat I am using currently just to try and see if I can get something to display and nothing shows up.[code]Just to make sure an alert works, I threw in a alert("hi"); which works fine. It is when I try to write out the session variable it fails.
View 8 Replies View RelatedI'm building a form in PHP. One of the fields needs to generate information based on another selected input. The first input is for "phase" and based on that I need to count how many entries there are in the database for that phase, then display posible positions(ie 1 per entry including the entry being edited/added). I know that this can't be done with only PHP.
I don't work with Javascript normally so I am struggling. I have read many similar topics, but can't find the answer I am looking for.
I thought that the solution could be to call an include file when a selection for phase is made, but I don't know how to pass the information to the PHP script.
I'd prefer not to have to reload the page or form.
Here's the code that I have so far:
Code:
<html>
<head>
<body>
<form action="edit-category.php?id=<?php echo $id; ?>" method="post"

I have an iframe....
<iframe src="somepage.html?var="tom";vartwo="jane";varthree="peter"">
Now....that is all great...BUT, I need to pass another variable INTO the iframe like the others (var, vartwo, varthree) and I won't have that variable UNTIL I do some javascript function to extract a background color from a div tag. Basically, I have to pass a bgcolor into the iframe so the resulting page will then display itself with a color that matches the parent page. Its a backend process....basically, the backend app needs "backcolor=" appended to the iframe.....BUT the iframe is loading first...so how do I do this?
How can I call functions from the value of a variable?
I do this in PHP, like $variable(); or {$variable . 'CallBack'} or using something like call_user_func().
I've been search all day though, and can't find how to do this in javascript. Is it possible?
I'm sure it's just a syntax problem. You can ignore most of this function because most of it works. The part I'm asking about is the "coordinates" variable 4th line from the bottom. The "office3" variable is a dynamically populated office number. I have the office numbers all defined as variables somewhere else but since I can't just name the variables as numbers I had to put a $ in front of them. Basically I'm trying to call the office number variable, $1656 for example. So "coordinates" is meant to be equal to "$+the chosen office number".[code]...
