This seems like a total beginner thing, but I don't know why it isn't working. I'm working from examples from a sitepoint pdf. Here's my html:
Code:
<body>
<h1 id="stupid">sdfasd</h1>
<p>sdjfa</p>
[code]....
When I run an if statement, I'll get an alert letting me know that the value of target is null, but why is it null? It should contain a reference to the h1 node.
I have a webpage with addition questions for numeracy training. I am storing the sums in a table(id="sums"), with an empty textbox(id=ans1) for the user to type the answer. After the user types an answer and moves onto the next Q, I want to activate a popup dispaying if the answer is correct or not. I am tackling this with onmouseout. The script checks the answer, then displays a confirm message if correct or and alert message if wrong. The onmouseout is not working
I must have a syntax error, because this function crashes the entire script (even the other functions).
function newNote() { allNotes = document.getElementById('notes-stickies-app').innerHTML; secondadder = 1;
[code]...
EDIT: to get to the stickies part, click the apple menu, and click stickies. you'll see how the stickies wont drag because this script that adds new stickies has a problem.
I have a pretty simple function set up to pull XML data into my page, but there's a couple things wrong with it. I'm REALLY new to J Script and really trying my best to learn, but for some reason I'm not yet adept at googling the right results :rolleyes:At the very bottom you can see the data from the first XML entry, so it seems the function itself is working fine, but it's not looping coorectly to access all the data.Also, I want to pull it into the "shows" div of the page, but can't figure out how to put it there (seriously, I am very new with JS). The code below is not working, but the live site has it added to the body, which does show the one entry.Here's the XML function, the XML data and the HTML markup:
Shows function -
function loaddates() { var xmlData = document.getElementById("tourdates"); var newDates = xmlData.getElementsByTagName("dates");
What kind of logical error am I making? I want the alert(); to execute if both of the variables (cjob and czip) are blank, but the only way I can get it to work is if I replace && with ||.
I cannot get the 2 getElementById functions to work and I am a beginner so I am sure it is something simple but I have not been able to fix it. I need to click on the text to change the font.
<?xml version = "1.0" encoding = "utf-8"?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns = "http://www.w3.org/1999/xhtml">
I'm a perplexed nube, and I can't understand how document.getElementById evaluates to true when no parameter is passed to getElementById. This code alerts 'foo' if (document.getElementById) {alert('foo')} else {alert('bar')}
Just to double check, this code alerts 'bar'
if (!document.getElementById) {alert('foo')} else {alert('bar')}
I found an example code browsing on the internet that I have used to put partly transparent pictures on top of a background image (a map with several areas), The partly transparent pictures is used to change the color of an area when that area of the map is clicked (I have put a transparent image map on top.) In my css style section the display for the pictures is set to display:none I now want to extend the script to make it possible to click on an other part of the background map and change the color of that area without changing the color of the first area. My idea was to use nested arrays for this, and thus reuse the function changeImage. To test this I tried to add a new array but for some reason it doesn't work.
I've got here a sample of my function which is supposed to fade a certain piece of text to another colour. This line is then located in a for loop and it works pretty well in IE 6. However, in Firefox, and thus I assume it will be the same in Netscape and Mozilla, it gives a problem with the: getElementById('main_txt'). Due to that in setTimeout("",) it requires the "" signes and thus I can not use the same ones in the getElement part. IE has no problem with using '' in there, Firefox, however, does. Can anyone think of how to get around this and make firefox do this?
Code: document.getElementById('all_days_div').style.display = 'none'; The HTML section containing the div the Javascript should be hiding Code: <div id="all_days_div" style="display:block;"> <p align="right" > Show All Days </p> </div>
When the JavaScript code is called, instead of hiding the div, I get the following error:"Cannot read property style of null" Do you see anything wrong with what I've written, or is my problem elsewhere?
I am trying to use document.getElementById in FF but its not working. There is a main page. in that mainpage there is a iframe and in that iframe (id = DocFrame) there is a textbox (id="fileuploadedcnt") which i am trying to access. there is no error. ofcourse i have given name and id to the textbox. Below is the code
In the abpve case i tried both the name and id properties. with Name property i get the HTMLObj alert but again it fails if i attach value method. And for id, it doesnt work at all
Code: I've got the content div to auto stretch to fill the content size, but the blocks at the side don't follow thru. I'm using some Javascript code I found here to fix that, and it does in IE6 and Opear6, but not in Firebird. For some reason it won't read the actual height I've already specified (in any browser), but specifically in Firebird it won't adjust the size.
I am using a text link to submit a form with the following funciton:
<a href="#" onmousedown="javascript: getElementById(form1).submit();>CLICK HERE</a> It works beautifully in IE but not at all in Firefox. I use the same piece of code to submit a form using an image and it works with the image.
Any one have any idea how to fix this in Firefox/Mozilla?
Why first or second case doesn't return the element? I debugged and I know it's id property is set in both cases, but no element return???
Code: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "[URL]" > <html lang="en"> <head> </head> <body> <script type="text/javascript"> //// first case //var tdiv = document.createElement("div") //tdiv.id = "div_0" //var element = document.getElementById("div_0") //alert("element: " + element) // second case var tdiv = document.createElement("div") tdiv.setAttribute("id", "div_0") var element = document.getElementById("div_0") alert("element: " + element) </script></body></html>
I am validating a three form field which takes temperature value between 0-50, humidity 1-100 & rainfall 0-200. I am able to see expected result for temperature value but not getting correct value for humidity & rainfall(still one can insert text in it..)
Here is my code-: <script type="text/javascript"> function validate_form(thisform) { with (thisform)
