How do i set a page element as a variable and change it?
Ive googled the internet like crazy for an answer for this, but couldnt find it. Im trying to create an animation. My question is, how do i change the width of a div onclick?
Essentially, I want it to add one percent of the value of the width of the div every one second.[code]...
I just donīt know the right syntax for this:
I want to change the css class of the li element from the name hidden to the variable filterVal, but i donīt know the right syntax.
I need to be able to change the variable in this line d.addBusDays(3); from the code below, based on the page title.
For example. Page Title 1 = 3 .... Page Title 2 = 6 .... Page Title 3 = 12
<p align="center"><br><b>Est. Shipping Date:</b><br> <br>
I have questions related to three operations using jQuery:refresh a div element on page lo append an element on top of the other elements in div change an image (pending/accepted) from the div's elements I know that there are tutorials for that, but i am so short in time.I just finished my PHP courses, and i am too tired to get into the jQuery magic right now.ere is the situation that i am confronting. I have to files: propune.php (which is basically the page that has the form and the div that should be refreshed/appended) and propuneri.php (the file that is handling ajax calls).

I'm doing a very simple expand/collapse function using 'slideToggle'. The button that triggers this event simply says 'Expand/collapse'. I want this text to change depending on whether an element is visible or hidden.

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?

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...
View 6 Replies View RelatedTo get value of element by id from document is very easy:
var example = document.getElementById('myId');
But what if I would like to get value by id from variable:
var example1 = '<a href="example.html" id="myId">lorem ipsum</a>'
Is there any way?
Is it possible to use variables as the name for a form element e.g.
<script type="text/Javascript">
<html>
<head>
<script type="text/Javascript">
var myvar = 1;
</script>
</head>
<body>
<input name="myvar" type="radio" value="radiobutton" />test
</body>
</html>
I tested the above and looked at the course. The name is shown as "myvar" and not "1", so I guess it didn't work.
I have several lines of code in different functions where I need to refer to elements in document.form.max, so I figured I would define it as a global variable called tb1 to shorten the writing. The result however is the page senses an error as soon as it gets to tb1.value, of which I can't figure out why since things work when I change tb1 into a local variable. I was under the impression that global = full scope, so I'm not sure what's wrong here.[code]...
View 12 Replies View RelatedI want to select the element by ID with a variable. Is it possible?
<div id="comment_132"> some value </div>
<script>
var n=132;
alert( $("#comment_"+n).html() ); // Why it's not working??
</script>
I tried and tried for so long to get this to work, but I just can't.
Here's what I did:
var testvar = document.getElementById('example').style.color;
alert(testvar);
Not only would the alert come up empty each time, but IE reports that "testvar" is undefined. Why isn't it working? And if I'm going about it the wrong way, how can I store an element's style info, such as font colour like in this example, as a variable?
I'm a new Javascript coder; it's still pretty easy for me to get snagged on stuff. Anyways, I had a question for a specific project I've been trying to figure out.
I have an element set with CSS to a width of 160px. What I want is a way for users to the site to drag a slider back and forth to set the width of the button. Some sort of smooth animation while this is happening would also be nice. I'd also like a way to set a max width on the element.
So, can this be done? I'm guessing it would use jQuery, but I don't really know.
I'm just trying to output a value, but whenever it gets to "var max = tb1.value;" it stops working. I can't find out what's wrong with my [code]....
View 6 Replies View RelatedI 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();

I'm trying to create a function which shows a hidden response when a button is clicked on.I also want to add the response to a variable which lists all the users responses.Here is my code now...
$(".yes").click(function () {var feedback = feedback + $(this).html();
$(this).parent().next("p").show("fast"); });
$(".no").click(function () { $(this).parent().next("p").next("p").show("fast"); });
$("#email").click(function () { alert(feedback) });
The bolded line is the part which isn't working.
I have a variable that contains Form Elements. So these elements can be eitther a :text either a :check box See code below:
var currentValue = $(targetedInput).val() ? currentValue = $(targetedInput).val() : currentValue =$(targetedInput).is(':checked')
I was hopping that this line of code would assign a different value to currentValue depending on what kind of object i have. My idea was that If the current Object is a check bot it doesn t have a val attribute..
but having fun with it. Would like tolearn how to do the following...2) Find the parent <li>.3) Grab the value of the attribute "jcarouselindex" and put it in avariable to be used elsewhere.Sample code below...
<ul id="carousel">
<li class="carousel-item" jcarouselindex="1">

What type of variable is an empty array element? I thought it was undefined, but i noticed that they have different behavior than undefined does:
var r=Array(1);
var s=r.concat([0,"",null,undefined]);
alert (s.toSource()) //==="[, 0, "", null, (void 0)]"
typeof s[0] //==="undefined"
typeof s[4] //==="undefined"
As you can see, 0 and 4 both === undefined. Yet, they don't have the same toSource()...
Is this special type named anything specific? Or more importantly, can it be detected outside of an array as being distinct from undefined? I am thinking this would be the same type as ({}).nonProp ...
I guess the question is actually, "can you tell the difference between uninitialized and undefined"?
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?

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]...
