In JavaScript (preferably jQuery) how could I create a new element and set its values, but I want it in a specific place In the document. My divs are structured like this :
[Code]...
I know how to do this and insert it before the end body tag, but not like this. I also say in jQuery, as most of my site is written in jQuery (only the js parts)
I would like to change all img tags with a certain class on the page as follows [code]...
I do not know how to "copy" the value of the img tag src attribute to the background url attribute of the div.
I am new to query. So far I have found this a huge improvement on coding all this stuff myself. I want to create a button which will add a new div element to the html page. I can do this in php however I want to know if there is a simple way of doing it in query and where I would look to find the documentation and examples of this function.
View 2 Replies View Relatedi'm sorry if this question has already been asked, but I searched for the term 'create element' on the jQuery Google Groups and didn't find the answer. I basically want to create html dynamically and be able to add it to my webpage. Suppose I have the following html:
[Code]...
I'm trying to allow a user to add several data items. I'm using append to add a new row where they can enter data. However, the element count only seems to get to one (the newest added) and does not create an array of elements like i was hoping.
[Code]...
In the above, i can successfully add new rows. But the item "the-data" will always alert that it has a length of 1, no matter how many rows are added. how I can add several of an element with the same name and have it recognized in the DOM?
I use following code to create an element and load data into it onclick:
("<div id="element" ></div>").appendTo('#content').load("grid.php");
The first time it loads very fast, 12ms.
I have a close buttons wich removes the element from dom: $("#element").fadeOut('fast').empty().remove();
The second time I execute the onclick event, the first code takes approx 1 second, so much slower. The php code execution time is the same as previously.
I could really do with a little help with dealing with an element that does not always exist please.
This is my first dip into jQuery and Javascript but I'm not a developer newbie I have 5 forms that share the same HTML (A Rails partial if it helps!)The shared HTML is a website preview and in one form I am allowing users to choose the height and width of the border around their website. On the forms that do not have the input fields available Internet Explorer throws a javascript error (Firefox handles the issue with no problems)
The idea is that as the values in the uinput fields change the website preview to reflect those changes as you type. The good news is that the code I have works! WooHoo! But it causes problems for other forms that do not have the input fields for the width and height available that also use the website preview HTML
The id's of the input fields are #website_layout_website_width and #website_layout_website_height

I'm using three elements and jQuery to create a scrollable information element with a sliding animation (similar to this. I'm running into issues when resetting those three elements to prepare for the next prev/next animation, however. The issue is in my logic - jQuery's selectors will reverse themselves using the code I have.
Javascript Code:
Original - javascript Code
$('#name.current').removeClass('current').addClass('prev');
$('#name.next').removeClass('next').addClass('current');
$('#name.prev').removeClass('prev').addClass('next');
$('#name.current').removeClass('current').addClass('prev');$('#name.next').removeClass('next').addClass('current');$('#name.prev').removeClass('prev').addClass('next');
As you can see, the last step will always reverse the first step These elements do need to be reset in one way or another so that the information can be loaded appropriately (from an XML file). and then animated again.
I have checkboxes which are created dynamically depending on the number of records being returned. With each row of the product being displayed along side the check box there is also a value called 'product rate' which is being returned for every product. I have to ensure via javascript that the products which are checked are all of the same 'product rate'. how do i do this? Please help me this is very urgent! I have tried a lot of things but it is not working. I took a hidden value for the product rate which again gets populated everytime the check box is created but i didn';t understand how do i create and check the values of the product rate for the ones which are sele cted?

I am very new to javascript, but I am trying to create a function that will get all the form values on the page and then create a link to a .php page with the form values passed using GET method. Basically its an update form to update a company's server information, which will then send the new and/or existing values to a .php page to update the DB. It seems as though after executing the IF statement, it breaks the for loop.
HTML Code:
<script type="text/javascript">
function GetFormValues() {
var elem = document.getElementById('server_form').elements;
theLink = '<a href="update_server_health.php?';
for(var i = 0; i < elem.length; i++) { .....
<script type="text/javascript" src="../gears_init.js"></script>
<script type="text/javascript" src="sample.js"></script>
<script>
var db;

how to create a table in javascript to display entered textbox values
I have a table with a date field in each row:
The table, and the input id element, are dynamically created from database records and I use jQuery live to initialize the datepicker for each field, like so:
The idea is that when I click in the input field, the datepicker pops up and allows the user to input a date. While the date shows in the input field in the table, the value attribute of the input field is empty. I can't use the getDate() method on the datepicker, since I can't programmatically connect the datepicker element in any particular row with the input element in that row. I tried the onClose method shown below, but that doesn't work either. Has anyone done this successfully?
I have a problem and I don't understand why this is happening.
Code:
calendar = document.createElement("div");
calendar.setAttribute("id", "calendar");
table = calendar.createElement("table");
After I create table element nothing apears on the screen.
Is it possible to create a link element in javascript like this one
Code:
<a href="modnodeform.php?nid=5" target="_blank" class="lbOn">a</a><br />
then pass it directly to window.open? In particular, I can pass the modnodeform.php?=5 to window.open but, I need to set the "class" attribute to then pass the window.open function.
It appears that using the insertCell method to append a cell to a table row in the tbody creates a data cell by default. I need to create a header cell (in the tbody, not in the thead). Is this possible? The desired result would be something like this:
<table>
<tbody>
<tr>
<th>#text</th> <-- I am unable to create this element.
<td>#text</td>
<td>#text</td>
</tr>
</tbody>
</table>
Where could I find examples of what I'm trying to achieve?
I want the JS insert a <span> within an <h2>
I've had no luck with createElement and appendChild
Is there a way to create a function that can be run on any element? e.g.:
Code:
element.function();
where this would pass the element into the function without having to pass the element as an argument?
I am trying to create select element using dom and also populate with data comes from database. The element create successfully but not populating with data. The Java code is:
Code:
function addItem()
{
var actnum=document.getElementById("theValue");

I'm trying to understand how to work the dom, and all I'm trying to do
is insert a link right before another link in the html based on it's
href value. This isn't a real world example - I'm just trying to do
this in phases to understand what's going on. I'm getting an error
(Object doesn't support this property or method) in IE and I can't
figure out what I'm doing wrong. Code:
Can someone see what is wrong with this code:
frm=document.createElement('form')
frm.action="/cgi-sys/formmail.pl"
frm.method="POST"

I made the game on the left side of the page two months ago in C++, and a month ago translated it to TI-BASIC on the TI-83, and then yesterday moved it to javascript. I've goota say, Javascript is the way to go! My headaches of TI-BASIC were instantly relieved when I went back to Javascript.
Now for my problem. There isn't really a problem in the sense that the game is fully functional, it's more of just something that bugs me. I created the game in hopes of making it as unobtrusive as possible to the page. The entire game uses 3 css classes and one JS Object named bloc. I want the game to generate its own div to live within, which it currenyl does, but I want the div to be name-less and ID-less, so other scripts in any page will not interfere. Code:
At the moment i am using javascript to show and hide elements to show notifications, but this doesnt work well because i can not show more than one notification, so i would like to be able to dynamically create and destroy elements like:
create element
set class
set innerHTML
display
wait for user input and destroy
i tried google already and cant find anything,
If I create an image element using the DOM methods and assign it an onload event handler, at what point is the image actually loaded and the event handler run?
So, given the following and assuming that "parent" references a node already in the document:
var elm = document.createElement("img");
elm.src = "myuglyface.jpg" // #1
addEvent(elm, "load", myHandler, false); // the standard cross-browser event adding mechanism
parent.appendChild(elm); // #2
Does the loading of the image begin at #1 or #2, ie when I first reference it or when it is added to the document? Can I even add an event handler at the point I do so?
I'm developing a chess game recorder (records chess games just like electronic score sheet) and i am trying to write a function that handles the "en passent" rule in chess. However, when i try to test to see if a Black pawn is at a particular x,y location, it is always giving me back "50px". Even when it's not at that location. i uploaded semi-live version to my website here: [URL] you just click on the 'Play' button to start the game here's the function in question:
[Code]..
var oxml = document.getElementById("xmlfile");
var oDom = oxml.XMLDocument;
var xy=oDom.getElementsByTagName("Name");
I was able to produce the below XML:
<root>
<Name Id="174" userid="A2 " level="1" selected="1"/>
<Name Id="175" userid="A5 " level="1" selected="1"/>
<Name Id="183" userid="A9 " level="1" selected="0"/>
<Name Id="110" userid="B1 " level="1" selected="0"/>
<Name Id="116" userid="B16" level="2" selected="0"/>
<Name Id="109" userid="B25" level="2" selected="0"/>
<Name Id="120" userid="C29" level="1" selected="0"/>
<Name Id="133" userid="D03" level="1" selected="0"/>
<Name Id="132" userid="D3 " level="1" selected="0"/>
</root>
What code do I need to write to traverse above XML code to retrieve those userid value only when the selected=1???? And display the userid "A2" and "A5" with window.confirm in Javascript
