Document.createElement Keeps Adding Everything On Its Own Line?
Oct 4, 2010
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 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:
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'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");
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,.
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 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?
I am trying to write a bunch of text onto a new document using document.write() and somehow need to format it to include line breaks.
For example: Code JavaScript: document.write(Line 1); document.write(Line 2);
I have tried including and it does not work. I have also tried document.writeln() and that also does not work. From what I have found on the Internet, one (if not both) of those methods should have worked.
var currentTxtBx = 0; function addTxtBx(){ if (currentTxtBx<10){

This just creates up to 10 text boxes when the user presses the button. However, the text boxes are placed side by side until they have to go on to a new line.How would I go about creating and inserting a line break so that after each text box a line break would occur so that they're all place one below another?
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'm using the script below to list files stored locally on a webpage (I'm developing a small application that is to be loaded from a CD-ROM). It's been done in HTML as per my company's request.
Essentially, this script works and successfully populates a list of files stored in the folder given by its parameter. However, I wanted a line break between the entries (hence) but it doesn't seem to work. I have tried the <pre> tag before and after the div this is printed to, as well as around the script - but it doesn't seem to have any effect. All I get is spaces. code...
I'm playing around with edit in place and have a list of information that is generated by a php loop. Each list has a unique ID number at the top that i need to send back to my php script. I've put the ID number in a hidden form field at the top of every list and i'm trying to read it using .val() I've used .prev to get the line ID but can't seem to get ID number.... I thought it would be something like this but i can't seem to figure it out... i $(this).find('.Id:first').val(); usally work my way though stuff but this is making my head hurt.....
I am trying to insert new lines inside an alert that is created by the document.write method. This causes the error "unterminated string constant". Is there any way around this? code...
I wonder if jquery or javascript has the function adding line breaks which can be similar to nl2br() in PHP? This is the info i want to grab from a database, PHP will add line breaks (<br/>) when it is passed into nl2br(),
I know for a fact that it is an object and I'm pretty sure that it isn't null. I will give you a link to the page that I'm troubleshooting even though it's embarrassingly ugly. Does anyone have an idea of why it's not seeing the <select name=finish> on Line 183 in <Form Name="myform">?
to load a CSS file should the browser not be JS capable. Only in IE 7 will this not render and I'm going bonkers trying to figure it out. After searching a bit I ensured no ID and NAMEs were similar and I don't think it's a hasLayout bug.
I am facing a certain problem when I try to add a content to a page dynamically and then save the page. I add a content dynamically to the page on a mouse click and then after the content appears in the screen, I try to save the HTML file from the browser. When I open the saved HTML file, I am not able to see the dynamically added text. This happens only in IE.
This is the code that I use.
"document.body.insertAdjacentHTML("beforeEnd", "<div id='idCanvas'> Sample Text </div>");"
This code successfully adds the new text to the page. But, when I try to save the page from "File -> Save As" and then open the saved file, I am not able to view that text. I need to get that text in the saved document as well.
