I want to insert something after #close, but only if the following div content contains the references-container4.Nothing will be inserted here. Only in the references-container4 case.
View 1 Replies View RelatedWhat's the best simple way to filter elements by their index similar to the nth-of-type equation an+b , regardless of parent and node type? Something like...
$("input").filter(":nth-of-set(3n+1)")
... to filter every third input element (3n) starting with the first one (+1).
I have dynamically created divs. Their ids all start with 'info':
<div id="info1a"></div>
<div id="info1b"></div>
<div id="info2a"></div>
<div id="info123456"></div>
I need a function to loop through all those ids starting with 'info' to put the display property to 'none'.
Code:
document.getElementById(startWithInfo).style.display='none';
Is there any way I can do that withoput having to specify the full id for every div that starts with 'info'?

I'm using this script to make some changes to a table which is only accessible via a class serverside:
Code:
The first part of the code is a script from Robert Nyman, [url] - my function is added at the end of the script. It works fine, but my page is dynamically generated and sometimes this element with the class name doesn't exist. This gives an error when the page is loaded: "getElementsByClassName("login-headline", "table")[0] is undefined". How can my function be rewritten so that it checks to see if the class is avaliable before running the script?
I found out how you can check if an array value exists but I can't seem to get it to work with the options array for some reason.
how I can find out if a certain select value exists?
I wonder if there any better method to check if the element in array B exists in array A, then remove it from array A.
Code:
var arrA = ['a','b','c','d','e']
var arrB = ['c'];
I copied and modified this code from somewhere I got it online, but not sure if I understand it as it has two for-loops in it...
Code:
for(var i=0;i<arrA.length;i++) {
for(var j=0;j<arrB.length;j++) {
if(arrB[j] == arrA[i]) {
var index = arrA.indexOf(arrA[i]);
}}}
code to remove element from array A,
Code:
if(index >= 0){
arrA.splice(index,1);
alert(arrA.join(" "));
}
I'm trying to check to see if a dynamically created element exists BEFORE creating another element of the same exact type...but my if statement at the beginning is not working and another element is just created.
function writeElement(id) {
if(document.getElementsByTagName('transElement')[0]) {
var id = id;
killElement();
writeElement(id);
}
var id = id;
var transElement = document.createElement('transElement');

When the page loads there will already be a drop-down on the page, here's an example of the drop down.
<select id="dropdown">
<option value="2121S">Option text</option>
<option value="2122S">Option text</option>
<option value="2123S">Option text</option>
<option value="2121A">Option text</option>
<option value="2122A">Option text</option>
<option value="2121K">Option text</option>
</select>
On page load it will evaluate this drop-down and repopulate it determined on their values. If there is an S in any of the values the drop-down will generate an option for 'S' like so.. <option value="s">S Option Text</option> And for the first code example in this post - the Javascript would be able to repopulate the drop-down with the following:

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'm trying to unselect element or not allow select element to prevent this:
How can i do this? This only happens on FF, on IE8 its fine..
My html:
I want to get the text between the second td. The 83:
<tr
bgcolor
="123014"
> <td
[Code]....
The table hasn´t a id ore something lime that.
Thought of something like this ;)
var kraft_cp = ('tr:has(td):contains("Kraft")');
I want to know how can I make it where if you right click on an element on a webpage it will select that elements id or whole html code?
View 1 Replies View RelatedI'm building a nested menu where I want to add background colors only to top menu items. I can't change the generated code, so I have to live with the id's and classes as is.Relatively new to jQuery so still not used to filtering my selections carefully—is seems to grab everything. Anyway, I have tried: .is, .content, .filter, and some parent, child stuff, but can't seem to only apply the effect to the "top" class—it just selects everything.

View 1 Replies View RelatedThere is simple html like this:
<ul id="icons">
<li class="icon1 hoverNow"><img src="some/pic1.jpg"/></li>
<li class="icon2"><img src="some/pic2.jpg"/></li>
<li class="icon3"><img src="some/pic3.jpg"/></li>
<li class="icon4"><img src="some/pic4.jpg"/></li>
</ul>
where class 'hoverNow' means, that opacity of the image is 1.0, while others 0.5. This done with css.
i want to do, that when mouse hover the 'li' element, image, IF it's not in the li element, who's having class 'hoverNow', become with opacity 1.0, and on mouseover, again will have 0.5 opacity. For this, i write this simple code:

is there a way where I can have the mouse when it right clicks anything in a webpage that it would have a drop down menu appear or fade in the drop down menu. In the menu I want to have buttons that once clicked it will run a function but it will send some values to the function as an argument. Now one value it will send to the function will be either the name or id of the element selected for example lets say for example a user image 1 got selected and only has a name. How can I select the name? like if the person right clicked this element how can I select the elements name or id ? I know how to pass it to the function but don't know how I can select the element without doing this manually in the code.

View 1 Replies View RelatedThe "checkbox select select select" part is included so it is identical in the 2 places (ie it is not possible to have different id's).What I want is that checking the checkbox only the selects next to the checkbox get visible.The only difference between the 2 checkbox/selects combinations is that the first one is in form A and the 2nd one is in form B.Is it possible to select only the selects in the same td as the clicked checkbox to make them visible?I tried JQuery's parent and sibling selectors but I am not sure if they fit my need here.

How can I select all empty elements?
I'm trying to craft a selector that returns all textboxes that are immediately followed by a label.
View 2 Replies View RelatedLet's say you have two elements, and you know their IDs; is there a way to select them both at the same time; something like $('#test #test2')?I realize I could just select them both on two different lines and apply the same function, or use class or something to track them down; but sometimes I just want to grab two elements by ID and do the same thing to them. I assume I'm just missing the syntax.
