i am editing a javascript game and im trying to get a heading (h1) to display the value of a variable in a javascript function however everything i have tried always causes an error.
View 1 RepliesIf I want to hide a title / heading if a field below is not filled in, what would be the js for that?
I have an "Attachments" h2 heading and three following fields for the client to add up to three attachments. But if none are filled in I want the h2 heading to not display.
This is what I have so far:
This should take care of the three fields, but how do I tie in the heading too?
I want to start javascript for fun, so I gave myself an assignment to use a for loop that will display "Hello world!" 6 times in the 6 different heading tags. The problem I'm having is that I don't know how to display it in the remaining 5 tags. I have it in the first one.
Here's my code:
<html><head></head><body>
<script type = "text/javascript">
var is = "<h1>Hello world!</h1>";
for (i= 0; i<= 5; i++){
document.write(is);}
</script></body></html>
I am having trouble getting my head around adding classes to elements "onload". I need to add a class to all "h3" tags onload. This is what I have...
function change() {
document.getElementsByTagName('h3').class = "red";
}
</script>
<body onload="change()">
I'm just learning javascript. I need one script for the following data. I'm having three headings.
heading 1
heading 2
heading 3
on clicking heading 1 it opens
subheading 1
subheading 2
on clicking subheading 1 it opens
subsubheading 1
subsubheading 2
My problem is when I open heading 1 it opens subheading 1 and 2, when I open heading 2, contents of heading 1 must disappear(switch contents) and only contents of heading 2 must appear. When I use style display: none, contents are moving on opening others.
I'm building a shopping website that within the products' page, there's an HTML select that allows the user to choose what product type he wants to view. beneath the select, there's a heading followed by a div or a table created at runtime showing the product name, image and a description.
My problem is in dynamically write the title. The designer provided me the prototype with a static heading in a span,once i try to automate it, the heading is created on a blank page not within the same page.
Here's my code so far:
I think the problem is in document.write and it's the way it works, but i need something to write the heading in the same place of the code.
I have a long table of information with a heading at the top. Is there a script to make the headings always stay at the top of my screen while the table information scrolls by.

I am fairly new to coding HTML with Javascript. I am hitting my head onto the table because i cannot figure out how to pull the variable value out in a document.write statement. Basically, I am calling a function to give me a random number between 1-4. I use that randomNumber to attach to different .jpg, descriptions, and URL's. So far, i have only got the image to display, but unable to get the link and description to display. Basically, i am trying to diplsay random ads and links like the one at the top of this page.
p.s. I know I am getting the randomNumber out of my function becasue I can call a simple document.write(randomNumber) and it works. Substitute adDesc and adURL in place of randomNumber and I also get the description and link respectively.

On my site there is information that changes several times a year and I want to make it a lot easier by having it change on all my pages at once. For instance the delivery time may change from 1 week to 2 weeks depending on the time of year. What I've come up with so far should work, but I don't know how to finish it, or if it's the best approach for my problem.
Since the sections I want to change frequently may have a bit of text I would link the template of my site to the external JavaScript file external.js. In that file I would declare the variable and assign it a value related to the shipping time (see below). code...

I'm trying to make a basic rss reader with a google reader-esque functionality of clicking on article names and being able to expand/collapse that article. I'm working on the expand part and am going crazy. I am having no trouble getting content and displaying it without the onclick function but when I try to integrate onclick I can just get the titles.

$displaytext = "display this text";
$(".image").mouseenter(function(){
$(".test").text("$displaytext");
});
I would like to display the text in the variable $displaytext in my div.test when I mouse over the .image div. But instead, it just displays "$displaytext". Anyone know how I could make this work?

When a person signs up for my website it first adds them to my external email list and then to my MySQL database.In order to do this you have to pass the information of the form to the next page where you can "display" it. Nothing except this display function seems to work.So what I am trying to do is take what is outputted by this display button and store it in a javascript variable. Then transfer this variable to a form which will auto submit and start the PHP registration pulling the output of the script, right now I can either get an undefined or the entire HTML code. Is there another option?Here is my code:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"

I have a question in javascript, that is, is it possible to display a value of an variable in another html page when a button is clicked?For example, i set a value in page_1. html as abc=5 and when a button is clicked the value of abc should be displayed in page_2.html.
View 1 Replies View RelatedI am looking for a push in the right direction for a few problems i am running into; my first problem is I have to create a script element that contains the function amountTotal which should return the sum of all the values in the amount array. There are no parameters for this function, and I have to add the following commands to it.
1. declare a variable named total with an initial value of 0
2. create a for loop thatloops through all of the values in the amount array, at each iteration of the loop, add the current value of the array item to the value of the total variable.
3. and after the for loop is completed, return the value of the total variable.
The amount array has already been created and populated in a list.js file, I had to first create a script element pointing to it.
This is what i had for my link to the list.js file and funtion :
I have my entire code written but i am trying to break it up and fix my problems 1 at a time: when i open the code, it does'nt display correctly ( which is another problem) but I ran the debugger and it says my total is undefined. ( this is in another section of my code), but I guess my function is wrong somewhere.
ive just got this script ive got set up and it works fine, but not what i expected.i want it so i have headings and when i click those headings sub headings show up and when i click on that heading again they dissapear however i also want it so that you can have multiple headings open at once .how would i be able to modify this code so that if i have say sub1 open and i click to open sub2 sub1 remains open
var persistmenu="yes" "yes" or "no". Make sure each SPAN content contains an incrementing ID starting at 1 (id="sub1", id="sub2", etc)
var persisttype="sitewide" enter "sitewide" for menu to persist across site, "local" for this page only if (document.getElementById){ DynamicDrive.com change[code].....
What happens is that when I click on a button, a random string from the RandomString variable appears below the button. e.g I click on the button and it displays 'AAB' and then if I click on the button again it may display 'AAE' and etc.
The problem is that sometimes it displays 'undefined'. I don't wanit 'undefined' to appear but why does it sometimes display 'undefined' rather than a Random string.
Below is the code:
if radio button checked display div #something else display nothing if un checkedcurrently I have this and it works but when I click another radio option the div that was activated before stays there. Want a div to show only if certain radio button is checked and if not checked to hide.
$(function(){
$('#offer_2').click(function(){
$('#total2').show();

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.
Ok, so I've built a member search using ajax to change the results each time a filter is changed. It works great, except one minor issue that I'm struggling with...I just can't specify dynamically in the parent file that linkclass$id opens linkclasscontent$id as I don't know of any way to pass that $id variable back over to the parent.
View 3 Replies View Relatedi'm not really sure how to explain this, since I know nothing about javascript, so i'll try and illustrate by the use of php (hope it makes sence)
I have a set of different links, like:
<a href="link.com?page=text1">text 1</a>
<a href="link.com?page=text2">text 2</a>
<a href="link.com?page=text3">text 3</a>
etc, where page is dynamic and can be anything I chose..
Another place in the same document, I echo out what the page variable is, like:
echo "$page";
so when clicking "text 1" the echo will output what i've defined the page to be, in this case "text1" ..
So I want to be able to click the links and change the output of the echo all depending on what i've defined in the link - without refreshing the page!
Is there any easy way to do this?
a.) specify two parameters for the changeYear function: today and holiday.
function changeYear(today)(holiday){
b.) in the first line of the above function, use the getFullYear() date method to extract the 4-digit value from the today variable and store the value in a variable named year.
first line
c.) in the second line; use the setFullYear() date method to set the full year of the holiday date object to the value of the year variable.
second line
d.) in the third line, use a conditional operator on the year variable. The test condition is whether the value of the holiday date object is less than the today date object. If it is, this means that the event has already passed in the current year and the value of the year variable should be increased by 1.
third line
e.) in the fourth line of the function, again set the full year value of the holiday date object to the value of the year variable.
