The document object has a method called createElement. Can I use this
method to create a new Drop/down list, like:
var sel = document.createElement('SELECT');
I have seen it used like this:
opt = document.createElement('OPTION');
which means that opt now holds an option that can be appended to an already
existing select object.
Are there any restrictions for which arguments createElement can be called
with? I have seen: var what is "LI"? Where do I need to look to find valid arguments for createElement??
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 have a table like above and want to use document.createElement to insert a new row at the end of the table before the close table tag, is this possible?
My efforts so far have resulted in the following html:
this works perfectly in firefox - but in internet explorer it just creates the first lable and the input field, although it creates the input field as a regular text field instead of for files. the caption label and text field aren't created at all. any ideas? Code:
This is driving me insane. I'm trying to use createElement inside a loop to make some <divs>, each of which has an onclick event. I threw together this test page to demonstrate it:
Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head>
[Code]....
When I click on any of the boxes it alerts "5", the final value of x after the loop ends, instead of what the value of x was when the loop executed and created the element ("0", "1", "2", etc.). This is happening if FF and ie.
I also noticed in Firebug if I put a breakpoint on the "yay.onclick=function(){alert(x)}" line that it will break everytime I click on one of the boxes. Very strange...
How can I put in a variable on the yay.onclick=function(){alert(x)} line and have it "stick"?
I'm having trouble parsing through a table in I.E. Of course it works fine in firefox and chrome. I'm pulling html off of a txt doc and storing it in a temporary div made with createElement so I can go through and parse out the data. Code is below:
[ Code: var tempdiv = document.createElement("div"); //create temporary element to store html content in tempdiv.innerHTML = html; //dump html content into new element
[Code]....
It returns 0 for rows and and cols. If I use a getElementsById and grab a table already on the page it works fine.
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've come up with this code and cant figure out why nothing appears when I press the buttonThe table is soposed to show. Probably something really simple cuz I often stuck on stupid things.
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:
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 integrate PayPal's MiniCart on my site, and I don't have much javascript experience. I did however find that this little blip of code is what's used to position where the cart is placed on the HTML page that contains the script. Here's my problem - I want to be able to create this element inside a div that already exists on the HTML page. Is this possible?
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)
What advantage does adding elements via document.createElement have over writing markup naturally with innerHTML?
[Code]...
The latter method has much more overhead and is considerably more difficult to write with. However, there must be an advantage of some sort to doing it this way, but it's not exactly clear to me why.
I have a slight problem with IE, when everything works with firefox.
The goal is to _create_ boxes using the createElement method. And then making it draggable with the mouse. The code example below is still very temporary, but I could not get IE to drag the created box, when firefox does it without problem.
The drag n' drop is straight from brainjar.com. Since their code works for hidden/shown divs, I guess it all has to come from IE's lack of DOM support and problems with it and the used method? Is there any solution around this problem?
I'd really like to avoid turning boxes on/off (ie, block/hidden or visible/invisible) because the potential number of them being present in the future page can be enormous. The advantage of the createElement method is that it allows for light pages and a lot of client-side treatment....
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]...
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 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.
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 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.
