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.
My code is this:
Code:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html lang="EN" dir="ltr" xmlns="http://www.w3.org/1999/xhtml">
<head>

In a few words it creates a button which when it is clicked it launches the add_text script. Add text script creates a text element for a form and puts a random value for the textbox. Textbox also takes a name which is of array type name="txt[]". Also form has the post method.
When I press e.g. 4 times the add text field button 4 text boxes are added. But when I click the submit button I get a result of 1 instead of 4 when the print count($txt) is executed. Copy paste the code to see the problem.
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'm having some problems understanding the append() function. What I'd like to do is select an element using it's ID and add a row to the table with a HTML form element. The table is dynamically generated using a Django template ( form.as_table() ) so I'm not able to alter the original HTML markup too much.
If I had a table like this...
I have created a form with malsup's Form Plugin wherein it submits on change of the inputs. I have set up my jQuery script to index drop down menus and visible inputs, and uses that index to determine whether keydown of tab should move focus to the next element or the first element, and likewise with shift+tab keydown. However, instead of moving focus to the first element from the last element on tab keydown like I would like it to, it moves focus to the second element. How can I change it to cycle focus to the actual first and last elements? Here is a live link to my form: [URL]. Here is my script:
$(document).ready(function() {
var options = {
target: '#c_main',
success: setFocus

Is there any way?
I have a javascript in the head of the document which has a variable named "ref2" ... ref2 is already working as I can see its value working in another function. I need to send this variable as the value of a hidden field in the form which is in the body of the document.

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]...

<div id="comment_132"> some value </div>

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]....

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?

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">
<a href="/someurl"><img src="someimage.jpg" alt="" />

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 tried jQuery('#calculateform').children('input, select, textarea').each(function(key){ alert(key + ': ' + jQuery(this).val()); but it goes only 2time throw (for each button it has)and it SOULD list all elemts (including hidden fields). I need each element with name and value.
View 3 Replies View RelatedHow does one cause a form element to appear ONLY if a certain form selection is made before it?
That is for example say there is a form element of type Radio called "format" so only if they select format value = normal then the form input fields called URL and Name are to appear as the next choices otherwise form input field Group and checklist Places are to appear as the next choices.
I'm using this bit of jQ to add a class to two different elements based on the class of another (parent/grandparent, etc) element.
First, when there's no class at all in <div id="main-content">, the 'active' class is added to *all* the #nav-primary LIs, and also to *all* the #aux-left DIVs; how can I modify this so that in the absence of any class on #main-content, do nothing?
Second, how can I target only the first or second of multiple classes to store in the 'containerClass' variable, e.g., <div id="main-content" class="apples bananas">?
I'm working on a script that will produce multiple dynamic forms based on the results of an ajax request. The ajax request does a db query that will return 0 to x number of rows. For each row, a new serialized form is created. Since the forms do not exist at page load, I'm having problems getting the value of the form elements so that I can run other functions on them (update inputs and selects). I've stripped down everything so that I can show a basic example. In the example, how would I get the value of "#orderID"? The body contains a div (previousList) that has a list of items that when clicked will trigger the ajax query. It also has a div (line details) that will hold all of the forms that are generated.
<div id="lineDetails">
check it out </div>
<div id="previousFrm" class="ui-widget-header ui-state-highlight ui-corner-all">
<h3>Previous Returns/Cancels</h3>
<div id="previousList">
<ul class="previous" id="returnList">
<li id="1000997" class="names">1000997: 101853</li>
<li id="1000995" class="names">1000995: 101853</li> .....
But callingconsole.log("order line value is " + $("#orderID").val());
results in 'undefined'.
I have a form in my webpage and i am referring to the form element as formname.elementname. But when i select 5000 records from one screen and goes to other screen the form in the new screen stops recognising its element. If i do not select 500 records from screen on and directly going to screen 2 the screen works perfectly fine. Any Known bug with i think.
View 6 Replies View RelatedI am using Ben Alman's JQuery resize plugin in order to obtain the varying computed width of an element when the window is resized (the element in question is a page wrapper that exhibits the expand-to-fit behavior of a block box, and it's computed width is obviously influenced by the resizing of the window. Essentially, what I need to be able to do, is to reference a variable that is defined in a .resize() function ('width_page') in a seperate .each() function.
[Code]...
I now understand that variables can't cross boundaries like in the example above, which leaves me a little stuck. I also understand that this is specific to the context of the .resize() function, and that it can't be taken out of it without using an element selector. Is there some way I can call the .resize() function in my .each() function?
I have 2 arrays:
var A1 = new Array();
A1[ 0 ] ="Y2";
var B1 = new Array();
B1[ 0 ] ="Y1";
B1[ 1 ] ="sink";
I also have a drop down menu with the names of the arrays. Say:
document.form.option[1].text returns 'B1'
Can I transform the string 'B1' into the array B1, so that:
document.form.option[1].text[1] returns 'sink'
Currently I'm doing this with conditionals, e.g.
if(document.form.option[1].text =="B1){do stuff}
but this gets a bit messy.
