All I really need is confirmation for this, but is this:
var variable1 = variable2 = variable3 = value;
The same as and just as legal as this?
var variable1 = value;
var variable2 = value;
var variable3 = value;
I am new to Javascript but fluent in C++ and other languages, I have a query, I made a global variable to hold string information, can the value of this string be assigned to a form input field value? I mean in the 'default value sense' I am just wondering if there is any syntax to accomplish this. EG in my javascript I have the string nameVal; It is a global variable, I would like to know if it is poosible access its value for use in the line below shown with italics, or is it basically always a case of 'type the value in manually yourself' and then rely on events functions to update the field thereafter?
Name: <br><input type = "text" name = "nameField" size = "50" value = my string val here onChange ="this.value=storeVal(this.value, '0')"></input></br>
I have an HTA I built for essentially email generation with tie-ins to our CRM here. I'm trying to make a section of the HTA do a Show/Hide style interaction. Ergo, if the section is relevant, click show to show the modifiable parameters, etc., if it's not, leave it hidden. I got this to work with hyperlinks but wanted to change it to an input button so when I'm processing the values, I can check if the sections is "instantiated" and if so, process; if not, skip. The weird thing is, I'm alert()ing on the reported value AFTER I set it and it is reporting as correct, it's simply not showing correctly in my HTA. Javascript:
Code:
function HideContent(d) {
document.getElementById(d).style.display = "none";

The goal is for selectedDay to be assigned the value of the system variable Mainpackage.subclass0.subclass1.firstDay and then incremented by two days. Mainpackage.subclass0.subclass1.firstDay needs to be unchanged.
Important system variable in red. To be 'manipulated and used' variable in green. Even with an intermediary, third, dummy variable it doesn't work:
Console log is:
It doesn't work in my webapp : All variables change at the same time.
I am currently writing code to populate a select tag with all the hours of the day. I recently rewrote a function that will populate a temporary select tag based off a time passed in as an argument and then return the temporary select at the end. When I attempt to assign the product to a variable, Javascript gives the error "Invalid Assignment on left-hand side." Have I stumbled onto one of the cases where you can't directly assign variables to each other, or is this a syntax error?
This the line that is giving me an error
eval(select1) = newHours('000');
Where select1 is a variable that contains the name of the day and a number, both of which change depending on input, hence the eval statement. The function newHours returns a temporary select.
I would like to be able to take some action (implemented in a
function) when a property is assigned a new value (much a page is re-
rendered when, for example, a style is changed). So if I do ...
myObject.myProperty = 5;
I want myObject.myFunction to be called. Is this possible at all?
I see that the cluetip plugin project is on github so, perhaps at some point I'll be able to try implementing this feature myself, and submit a pull request. My team is using the cluetip plugin in a rather exceptional way. Rather than a tooltip like msg bubble that appears on mouseover, we show the cluetip on page load and require the user to dismiss it. We're using these cluetips to communicate new features on our site. After looking at available jquery plugins, cluetip seemed to be best suited for this use (all be it, a rather exceptional use).
The current design allows for this use with just a bit of css work but it limits us to one cluetip visible on a page at a time. Multiple cluetips are not possible because the cluetip div container has a non-unique id and the jquery id selector is used in the plugin code (which means that only the first cluetip in the DOM is ever referenced by the code). I'd like to extend the code to allow for dynamic assignment of the id on the cluetip container which would allow us to render multiple cluetips on the page. Perhaps, this might constitute a new plugin, since this isn't really the intended use of cluetips.

How to assign value to an input filed using jquery.
I have a webpage(with a text field and a button) which prompts for a
local file and attempts to load the file in the window if the user
clicks on the button. The javascript code onClick event uses the
location.href property to achieve the desired result. (This loaded
page has some additional functionality which lets them upload the
contents to the server.)
This approach only seem to work for some computers and on others it is
loading a blank page. I have alerts in the code to show that
location.href is correctly reflecting the file location after the
assignment. When it is loading the blank page I see the message
"Opening page about:blank" on the status bar. Iam currently using IE6
sp1 on Win2k. This issue is not just limited to this combination. We
are experiencing issues with IE5.5, WinXP as well.
The code works if I pass a web site address. It only fails if I
attempt to pass a file name(c: est.htm)
Any thoughts on why the blank page is being loaded or how can I go
about resolving this issue.
For my web assignment we have to put in interactive elements into our web pages. The one I'm having trouble is a confirm button for a form, (it doesn't send any info as we have not been taught any php or any form of server side scripting yet). What I have want the button to do is to check that all feilds have been entered info if they then thank the user and close pop up div, if not request the user to enter info into all fields.
My code does sort of I want but doesn't thank the person if it is all filled instead it says please enter info into all feilds and then closes.
- Create a function that prompts user for a number.
- Develop the program so that it continues to prompt until it receives valid information.
- Then create a multiplication table that displays the number multiplied by 1 through prompted number.
How to get the function to work.
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.

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.

I start outside of the external JS file by: reviews.init(); reviews.initialiseContent('comment'); This loads my data and loads + sets the comment tab as default. My problem is that in the external JS file (shown below) the loadTabs variable will not allow me to pass it a variable: contentDiv.onclick = this.initialiseContent; Whenever I pass a variable here it errors, am I setting this up correctly, should I be using prototype for my this. variables? Interested to hear back on if this structure of code is the right way to go about this and also how I can pass a variable in this way :)

I have a programing problem that have been around for ages. I have search on google using several expressions and words and after hours of digging i'm still unable to do it.I would like to get a value from a HTML page hosted remotely with an inconstant value. Then define this value and name as a javascript variable and apply or show in my page.P.S. Is there any way to make a domain lookup in javascript? I mean a user enters a domain and the script converts to an ip and shows to the user. If not thanks, probably it can only be done in the server side...
