Document.createElement Element - Remove 'div' Before Returning The Function
Apr 18, 2011
I've written the following small feature test.
[Code].....
I want to remove 'div' before returning the function. Testing in IE something like div.parentNode.removeChild(div); will fail. If I look in the dom 'div's parentNode is null, so that explains that. It needs to be appended to something first I guess.
I am attempting to create an element (to be added later to the document DOM) using createElement.My test case is just:document.createElement("<p>Hello World</p>");My error console shows the following error:
I'm trying to create something just like Gmail's attachment feature where you could add a new element (created on the fly), but could also be removed dynamicly. So a 'remove' link would also be 'created' for each field created. Code:
I have a page which uses JavaScript to create form elements using document.createElement('input'), etc.. Both Firefox and IE have no problem accomplishing this and when the form is submitted all the information is passed correctly.
I am now trying to validate the form using JavaScript when the page is submitted. Firefox has no problems with this but IE returns 'document.form1.*THE FORM FIELD*.value is null or not an object' for the elements that were created using document.createElement when I try get their value using 'document.form1.*THE FORM FIELD*.value'. How do I get the value of the form elements that were created using JavaSCript?
I try the following in Firefox and other modern browsers:
window.addEventListener('load', function() { document.title = CSS.getClass('fontSize'); var div = document.createElement('div'); document.getElementsByTagName('body')[0].appendChild(div); alert(div); alert(div.style) }, true);
It works fine in normal HTML mode (Content-type: text/html), but in XHTML mode it alerts "[object Element]" instead of "[object HTMLDivElement]" and the second alert shows "undefined" instead of "[object CSSStyleDeclaration]". So I can't reach the style declaration which is important for me. Strict mode makes trouble again and again, the biggest bug: document.write does not work:
I've been creating a script that dynamic loads js files.
but after creating that script, (and i use document.createElement('script');) in that function.. i've realise that the code that shows up in the browser is:
I'm experimenting with creating SVG dynamically and am finding that document.createElement is changing the case of the tags I input. This is breaking because, apparently SVG tags are case sensitive. For example, when I try to create a linear gradient element like so:var grad = document.createElement('linearGradient');what appears in the view source is:<lineargradient ...> (Note the lowercase "g")The tag doesn't work if the "G" is lowercase. Is there any way to specify in the <html> tag (or somewhere else) that the document should preserve tag case?
My entire working code without the onchange i'm trying to pull of is:
Code:
// Create the Input Field var inputEl = document.createElement("<INPUT TYPE='text' NAME='state'>") inputEl.setAttribute("id", "stateSelect"); inputEl.setAttribute("type", "text");
I'm using the document.createElement method to add dynamic table and from elements to a page, but I'm running into a problem where I'm adding 2 objects to 1 cell. The two of them combined are not wider than the cell, but they won't display next to each other, they're always on their own lines and I can't figure out why...
HTML Code: var hiddenElement = document.createElement('input'); hiddenElement.setAttribute('type', 'text'); hiddenElement.style.cssText = 'width: 100%; display: none;';
[Code]....
The text input (hiddenElement) should fill 1 line of the cell, but then the two buttons (createButton and cancelButton) should both sit on the line below it, but the cancelButton insists on siting on it's own line below the creatButton, and I can't figure out why.
(I know they have their display set to none, that's being set to block by a function, which is how I know they're all on their own line)
MSIE 6.0 apparently does not support protyping with objects created with document.createElement, while Firefox does.
I tested it by typing it into the adress bar, but it also appears to be the case for code embedded in a HTML document. Here's a simple segment of code to demonstrate the difference:
javascript: function myObj(){};myObj.prototype = document.createElement('a'); var x = document.createElement('a'); var y=new myObj(); var z= new Object(); alert(x.href) /*blank in both FF & MSIE6 */; alert(y.href) /* blank in FF but 'undefined' in MSIE6 */; alert(z.href) /* 'undefined' in both FF & MSIE6 */;
I wonder why that is (apart from the fact that MSIE implements JScript and not javascript), and can anyone tell me which of both browsers is complient with W3C standards?
In IE6 and below, when using createElement and appendChild to add a new select element to the page, it automatically selects the first option.
the page relies on using the onchange event of the select element, and if there is only one option and it is selected, there is no possible way to fire the onchange event.
To get around this, i've had to use innerHTML to build the select element, which I feel is dirty so I want to clean it up.
Any idea's? I have already tried setting each option's selected value to false, etc but nothing other than using innerHTML seems to of worked,.
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'); [Code]...

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'm writing this javascript to place dynamically created images into a page, it works as expected in FireFox and Chrome, but not IE8, nothing appears and I get no error message.
I'm placing the images into this DIV:

And have written this code to place the small images into the DIV:
The following code nicely gets the element ID for the element under the mouse on the mouse down event. It ignores a disabled element though I am assuming there is some way to get this done!
// IE is retarded and doesn't pass the event object if (e == null) e = window.event;
I'm having trouble placing some data returned by an ajax function in the page where I want it.
I've included the relevant html and the javascript function below. There is some php code included which works but is not relevant to this question. The first ajax part of the function works. I have tested it with positive results in another context.
The part starting with "var x . . ." is the part that is not working. This part is supposed to generate the following html: Code:

if the dt-element in one of the definition lists has a specific css-property (e.g. length > 100px) then the dd-element with the css-class "subtitle" in the same definition list should be removed.
I am trying to write a function that is being invoked when some one clicks the submit button on the form.<form name="sectionA" action="optionpage.cfm" onSubmit="return abc()">I have three tables with initials textboxes. I want to check if they are empty and return false(stay on the same page), else go to action page.Here is what I am doing, I Created three functions tableA(), tableB(),tableC() call them from function abc(). These functions tableA(), tableB(), tableC() return false if one of the field is empty and stop furthur processing and remain in the same page. If none(errors), then go the other page.i.e if table B has empty fields, page should stop furthur processing and remain in the same page.Here is how I am doing it Can somebody please point out what I am doing wrong here.Even when there is empty field, the code moves me to the actionPage.
Using advice from this newsgroup, I tried this JS to create new DOM elements on-the-fly
var divSidebarItem = document.createElement("div"); divSideBarItem.setAttribute("class", "sidebarToDo");
but I get a JS error on the second line "divSideBarItem" is not defined when I try and invoke the "setAttribute" method. Is there a better way to create an element with attributes or is there something wrong with the above?
The following code is supposed to return a variable containing text, currently the code posts the data but returns an "undefined" variable. Can someone tell me what's wrong? code...
I am trying to remove a child node from an XML document and running into issues. I keep getting errors about not being able to find the child node, even though it very clearly exists.I think the issue is that most examples I've tried to follow only have the root element, then the nodes, but I have a root element, then another level (mapSettings & mapObjects). I don't know how to tell the remove child command that it needs to look in the mapObjects section.
