I can get the outcome of this function into a variable that I can then use later on. At the moment it obviously alerts the answer but I just want that answer in a variable.

How can I make my alert work? Right now it is undefined and I need to make my function in the variable global. Can this be done?
Code JavaScript:
I am trying to create a new global variable in a function with a custom name. I need something like this:
function newVariable(name){
createVariableWithName(name);
}
I tried creating a global function to calculate the distance between 2 points.
jQuery.distance(p1, p2){
var dx = p2.x - p1.x;
var dy = p2.y - p1.y;
return Math.sqrt(dx^2 + dy^2);
};
Somewhere else within my code, I declare a new variable in order to store the value returned by the distance function.
var distance = $.distance(particle1, particle2);
However this is not working.
I want to make different style of alert box on my code how to make user choice alert box.

View 1 Replies View RelatedI have successfully installed the datepicker jQuery plugin...works great. Here is what I am trying to do, and have not been able to figure it out. I would like our clients to be able to select any date that is past the current date, BUT, if the selected date is within 72 hours, I would like a popup javascript alert with a custom message.
i.e. Today is 7/30/2010...Bob selects 8/1/2010 from the calendar. It returns the date in a MM/DD/YYYY format to the form...and an alert pops up letting Bob now that availability may not beguaranteed.
Update: I have been playing with the code a bit....One way I am attempting to create this is by setting the 'defaultDate' to +3d and trying to create an IF statement that will alert if the selectedDate is smaller than defaultDate.

I'm working on a script that will take the selected div and add an input to it.
If the div id="3" then when I alert it it works right but if the div id="post_3" then I get an alert of "object HTMLdivElement"
The javascript is simple(so far)
function create_reply_input(post_id){
alert(post_id);
}
And here's the php i'm using to populate the page with the posts
<li><a href='javascript:create_reply_input(post_$div_id);'>Reply</a></li>
How do I get the line break to work in an alert box based on data from this php variable?

I have a problem that 'test' is not passed. The following function alert undefined, but it should alert test. Why that?
View 1 Replies View RelatedI have what I think is a strange issue but others may see something I am missing.I am using AJAX functionality to process a php script on a server and then place the output of the script into a div element.Here is the code snippet
Code:
function doWork13(typeCode,colorBlockName,objectCategory,imgID){
httpObject = getHTTPObject();
if (httpObject != null) {[code]....
This code shown here works perfectly BUT....I do not want the alert message to be there. When I remove that line of code the script fails to function. There is no error just nothing happens.The function is to replace one image with another and the variable in question is simply the ID tag of the particular image being modified.As I said it works with the alert but does not with out, could it be a timing issue in that the alert gives enough time for the if statement in the setOutput13 function become TRUE
heres my code:
Code:
<script language="JavaScript">
var checkobj
function agreesubmit(el){[code]....
i need to make it like if the button is clicked and there the agreement checkbox is not checked.. it should give an alert that the alert is not checked.. i know that would require a if and else statement but i cant figure out how to do it
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 must begin to say that I'm rather new in wtiting and using JavaScript. Now
I want to use JavaScript in a HTML-page. On the homepage is a link. Every
time the homepage is displayed the link must point to another target. I want
to realize this by having a lot of differet targetpages. The names of these
pages are p1001.htm until p<nnnn>.htm. At this moment the last is p1153.htm,
but the amount is increasing every day.
I have a file named "counter.txt" which contains one line with the string of
the last targetpage, at his moment "1153".
My idea is to have a JavaScript which:
1. reads the file counter.txt to determine the last available page
2. then takes at random one number between 1001 and 1153,
3. sets the HREF-link to page p<random>.htm.
I know it must be possible in JavaScript, but can anyone help me?
How would this be written on .js file. I need to create a variable named dateString which is equal to the following text string: weekday, month, day, year.where weekday is the name of the weekday, month is the name of the month, day is the day of the month, and year is the four-digit year value. (HINT: Use the wdayName array using thisWDay variable as the index value to display the weekday name, the monthName array along with the thisMonth variable to display the month value, and the this Year variable to display the year value.)

How can you use an integer as an object? The idea is to create dynamic object according to a particular id which is an integer
var newObject = function(integer) {
window.integer = {};
}
I cannot console.log(window.123), only console.log(window.integer) ...
how I create the object window.123 or perhaps, window.id_123 ?
I am trying to create a javascript alert box which only alerts when there is data inside in the alert function. The information I want to display comes dynamically from the database. As such, when data is populated I want the alert to display. When there is no data in the alert function I dont want any alert box appearing. The way it works is the data comes in dynamicly through a placeholder @data@ I put in the javascript. Depending on the actions of the user this will populate with data or nothing at all. Code:
View 2 Replies View RelatedI'm using jquery/ajax to create some links with window.open method. Here's the relevant code:
$("#content").empty();
$.ajax({
type: "GET",[code]..........
Basically, when you click a link a function is called with a parameter based on the particular link you run. Then the code runs through an xml file, and if the parent of the nodes I've cyling through has a value equal to the parameter past to the function, that node is used to create a new link with window.open function attached to it.It all works, or seems to, and when I alert what is being built, it looks right to me, yet the links don't work.I've attached a copy of one of the alerts of one of the links as it's built.
