JQuery :: $("selector" - Code) And .html() - Load Div In A Variable - Modify It In Another Variable And Then Change The Document Injecting The Contents

Dec 13, 2011

I want to load an html div in a variable, modify it in another variable; and then change the document injecting the contents.

1. I load the html to be changed in a variable (code)
2. I modify an attribute of <param> using attr() and I put the result in a var (newcode)
3. I change the html in the doc

I've used the debugger, and all steps give the expected results, except of newcode.html(), which is a null string. Why?

Change Variable Value On The Fly

Jul 1, 2011

I have a js script that produces a calendar and will like to move previous and next. When page loads it checks if month, year is already defined or else use the current month, year. and when the previous button is clicked calculate the previous month and change the month variable. I can get the month and year value to change, but it does not affect the code again. i.e because i have already declared month value at the beginning of the code, if i change the value via an onclick the new value won't affect the code, which i want to. This is the code that is relevant to what i am saying

cal_current_date = new Date();
var month = returnMonth();
var year = returnYear();
function returnMonth(nMonth){
var month;
if(nMonth == undefined){
month = cal_current_date.getMonth();

Change Focus Using Variable

Jul 23, 2005

I'm trying unsuccessfully to use a variable in a script that changes focus.

Depending on which link a user follows (navigates via keyboard or
clicks), I'd like to change the focus to an input name="q" in different
forms on the page.

<A onClick="changeFocus('basicsearch')"
HREF="#basic">basic site search</A>

<A onClick="changeFocus('advancedsearch')"
HREF="#advanced">advanced site search</A>

The script I have is:

function changeFocus(category) {
document.'(category)'.q.focus();
return false;
}

It doesn't work. I'm not sure how to insert the parameter into the focus
statement. What am I doing wrong?

Change Value Of A Variable Using An Event?

Jul 22, 2011

Well the topic pretty much sums up the problem. I'm pretty familiar with using events to alter the value of an html tag or attribute via the DOM. I was wondering if it is possible to use an event to alter the value of a variable within. Well I wrote the script below to test that and sure enough it didn't work. So if by some chance it is possible to use events to do alter the value of a variable, how does one go about that?[code]...

How To Detect Variable Change

Feb 3, 2011

I've been looking at Eli's object.watch [URL] script and I understand the idea of it and what it does but I'm so confused about how I actually use it in my script! Even if this seems quite obvious to most, I'm just not seeing it I might even be trying the wrong approach to it entirely and object.watch isn't what I actually need to be using!I've got my script here:

Code JavaScript:
<script type="text/javascript">
jQuery.fn.elementlocation = function() {

[code].....

Now as you can tell, the server load will be pretty high with the mouse move constantly calling data from the fetch.php page through AJAX. SO, what I'm trying to do is only call upon the AJAX when the variable "block" changes it's value. So I assume, I have to somewhere store a value, and then when the value changes check it with the stored value, but of course, the stored value will always change to the new value too since it's all determined by constantly changing variables? So how would I get it to only call the AJAX section when the block number changes?

Access/change Variable Inside Lambda Function?

Aug 17, 2010

In one of my functions I got the following lambda function. It works as intended, but I got a tiny problem. I'm trying to access the function-scooped variable "matched" and set it's value to "true". The problem is that it seems like the variable is existing as a local variable inside the lambda function, even if it's not declared inside the lambda function itself. So, the change "matched = true;" does not effect the variable that I declared.

Code:

//... code
var matched = new Boolean(false);
xmlhttp.onreadystatechange=function() {
if(xmlhttp.readyState == 4 && xmlhttp.status == 200) {

[Code].....

JQuery :: Cross-Browser On Variable Change Call Back

Jul 1, 2011

I want to bind a hook to objects member variable change event i.e. lets say I have object:
var obj { var1 : 1,
var2 : 2,
var3 : 3
};

I want to call "Magical" function like this:
onVariableChange(obj, "var1", function(obj, varname, old, new) {
alert("Variable " + varname + " changed from " + old + " to " + new);});
And after this function call every time obj.var1 is set to some value have my callback function called

I found something in internet: [URL]. Its cool but:
-It is changing Object-s prototype
-It is not working under IE 5, 6, 7, 8, 9, 10, 11, 12....
I've changed it a little bit and instead of adding to Object class prototype I'm adding it as member to any object which needs this hook. But IE still doesn't work. Is there any known cross-browser solution for this? I remember there was a jQuery upcoming project which would allow users to bind object to form and by changing one other will change automatically I wonder whats that project name and how they change input value when object member value changed.

Declare A Variable Inside A Function - Returns White Space - Not Variable Value

Aug 17, 2010

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.

JQuery :: Specifying Variable In Parent To Match Variable In Ajax File

Oct 21, 2011

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.

Onclick Defined Variable - Print Variable Some Place In Document

May 28, 2007

i'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?

ChangeYear - GetFullYear - SetFullYear Functions - Extract The 4-digit Value From The Today Variable And Store The Value In A Variable Named Year

Oct 13, 2009

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.
