Attempting To Create An Element (to Be Added Later To The Document DOM) Using CreateElement?
Jun 18, 2011
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:
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 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 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?
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)
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?
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 have the following problem. I am displaying and printing a PDF file that is generated by my Application server. The print dialogs comes up correctly for the small PDF for the larger PDFs ,the print dialog for the Acrobat reader does not comes up. I believe this is because print method is called before the complete loading of the PDF document. Code:
So I didn't know whether to put this in HTML & CSS or here. So I'm just going to put it here and the mods can move it if needed.So I had this script working for auto width of a DIV, then I added DOCTYPE to the top of my document, now it won't change the width ha ha. I have tried with all DOCTYPE's and same thing.The JS I am using is:
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:
Code:
And have written this code to place the small images into the DIV:
I've found a few posts on adding an event to a dynamic element, but that doesn't really help me. What I'm doing is allowing the user to add a textbox, then when a button is clicked i need to find the value for that text box, but it doesn't seem to pick up that the textbox is there.
Oh and that textbox is part of an array of textboxes, all of whose values i need.
I am creating a script that runs in tandom with several others. One of the other scripts creates and modifys the DOM on the fly.
My job is to write a script that will trigger some code when one of those DOM elements is created. The tag I have to watch for can be dynamically created, removed, and then created again with different childs, data, and subtags.
I have to log each of those newly created DIVs and all the child tags and data therein. I know how to do the logging, this is just an FYI. I know how to scan an existing DOM for the tags but not how to have a script monitor the DOM and fire off an event when these things are created on the fly.
I've been googling, yahooing, and asking for a day and a half now. Figured I'd start forum posting.
I have a jQuery plugin that creates a list of news items and appends the <ul> to the element(s) calling the plugin. Each <li> gets a document key added to its data.
A brief snippet of the code:
(function ($){ $.fn.NewsList=function (options){
[Code].....
None of the <li>'s have the data attached to them. I've tested the selector shown above in line 3, and it does pick up the correct <li>'s. The data is not visible in Firebug as it is on the other page. Both functions are called after document.ready and insert the elements after page load.
The onlydiscernible differences between these two circumstances is that in the working case, the plugin is called against an ID, whereas in the nonworking instance, it is called against a CLASS. In addition, in the working case, only one DIV is affected, and in the nonworking case, there are two DIVs that receive the treatment.
<div id = "container"></div> <div id = 'containerItemTmplt' class = "ui-widget-content"> <div class='contentHdr' onclick="test(this)" /> </div>
i then use jquery to clone 'containerItemTmplt' and add it to 'container':
var copiedElem = $('#containerItemTmplt').clone(true). .attr('id', 'paneI1') .appendTo('#container');
This works great and i confirm using I.E. 9's developer's tool utility that the element was indeed added with the correct id as a child of 'container'.
However in my test method, when i inspect the element that was copied, the id attribute is an empty string:
function test(elem) { var parentItem= $(elem).closest('div')[0]; alert(parentItem.id); //<--this displays an empty string despite }
I am selecting an image as part of a html form. Once selected, jQuery assigns a user-defined attribute of the image to a hidden form variable and passes it to form handler. Problem is when I dynamically add images that can be selected. I am using live function to ensure that the dynamically added image is highlighted when clicked - but the user-defined attribute is not being grabbed by jQuery.
I think that when the page is first loaded, all the existing image attributes are loaded into the DOM, but when extra images are added with ajax, the DOM doesn't have the new attribute values, despite them appearing in the html on the page. I don't think I can use the live function in this instance, because an attribute is not an event. Out of ideas now. HTML/PHP, with jQuery:
In my application I render a couple of elements dynamically after the user selects an option in a dropdown list. When the user selects another option in the dropdown, I want to remove all the previous elements that was added dynamically. I've tried with the .Remove() function, but it seems the elements cannot be found in the DOM. I've looked a lot at the .live() events. Does anyone now how I can solve this?
