I use Google Chrome because of the Javascript debugger that comes included and I keep getting the following errors with my AJAX script
Code:
Uncaught TypeError: Cannot call method 'getElementsByTagName' of null option.html:23
Uncaught TypeError: Cannot call method 'getElementsByTagName' of null
option.html:40
[Code]....
What is supposed to happen is I press either button then it calls either getoptions1() or getoptions2() which then lists the options using listoption() Then the user selects a color and setoption() gets called. I'm having a problem with either getoption function or the listoption function.
I've boiled down my code to the essence of the problem; a variable which serves as a parameter to a function keeps coming up as 'undefined'. The code is quite simple:
I did find the javascript twice in my code, once in the header and once here, so i removed it from the header. I also changed to src to the full url. But i am still getting this and i dont know why. the file is located in the root directory. found a solution. basically Internet Explorer is crappy and doesnt like the setAttribute property so had to change the onchange handler by directly changing the attrbute for the object like so.object.onchange = function() {}i have no idea what they means, does that mean i need to change swfobject.js or does that mean i have to change my xml request. and if it is the swfobject i have no clue what they mean or what lines
And I want to save all the text ("all" meaning the tags and everything) between the <td> and </td>. Using JavaScript, I was able to isolate the <td></td> by doing:
var w = myTable.getElementsByTagName("TD");
So then I have an IF statement within a FOR loop that looks like:
if (w.item(i).className == "regular1b") alert(w[i].childNodes[0].nodeValue);
The ALERT() is just a place holder to make sure things are working. The thing is, nodeValue returns NULL because there's no actual text within the <td></td> tags; the only thing there is more HTML code, and the text between the <span></span> apparently isn't considered part of the <td></td> tags.
I'm using the getElementsByTagName method to obtain a customer listing of records. So far so good. However, I also want to reference the child nodes of the customer records.
I'm trying to run a script that runs in every browser except IE (IE 7) this is part of the script [code]...
On every other browser the alert(listLines.length) give me the number "16" that is the number of 'li' tags but in IE7 gives me [object] so as soon i get in the 'for' the scrip stop in IE.
I have tried to get an event listener to listen for when the user presses Control-D on their keyboard. This would trigger a confirm delete function - if you've ever used QuickBooks Ctrl-D is the command that does this and this is a financial application.
Problem is that in FireFox, Ctrl-D means bookmark the page and this window pops up. I want to "return false" before this happens.
On this subject I would also like to take over Ctrl-C and Ctrl-V eventually but with Ctrl-D it will work for anything. here is what I have. Again, IT WORKS, but doesn't stop the natural event (bookmark page) fromhappening:
Code:
function AddOnkeypressCommand(strCommand){ //---- version 1.0, by , last edit 2004-12-14 //add to array of commands: m_onkeypressCmds[m_onkeypressCmds.length] = strCommand;
In my website i am planning to do portfolio things in that i gave fade in fade for all images this is working with same size of image.But i have images like this sizes 500/300, 300/150 like if i give this images into portfolio that time if one image fading to another one means that time small size imGE is going top or bottom like that ,I alighed as center.

I have a single page with a single form, but I have split the form into 3 divs for styling purposes. I have some java script that is supposed to pull values from the text fields, and put them in a selct box using 'document.forms[0].name.value', but nothing is happening. I am wondering if having the form split into to divs is causing the JS to not be able to find the fields, using the forms array? Here is the form portion of the html code:
I have some img tags in my HTML code, and I am trying to implement some manipulation on each image. Thing is, when using document.getElementsByTagName('img'), the JS engine skips every 2nd img tag, so I get an array with only half of the deal.
Here's the deal, If I access the page directly on my pc via the file system (i.e. I open up the file via: file::/path../main.html, the page and script runs just fine.
If however I point the browser to tomcat i.e. localhost:8080/blah firefox spits out the error: getElementsByTagName is not a function.
Any thoughts or pointers? I'm totally confused over this..this is a built in function call?
note: I did an instanceof on the object making the call, and it does indeed confirm it is an object.
ps. I have confirmed I can access the all scripts/css files from the webserver (tomcat)
System: FireFox (1.5.04), Tomcat, IE6 (also fails, even though I haven't found out how to see the js error details?)
Are there any ways to edit the html within an element without knowing the TagName?
I'm trying to add html code within a <td> element that has no name or ID. What I do know is that it's the third <td> element within the only <tr> in the table. Assume that none of the elements in the file have IDs or names. The html is produced by a compiled program, so I have no way of editing the HTML in order to add names or IDs. Code:
I've been given an assignment to create an alert message everytime a link is clicked on a page. It can be 10 thousand links on the page. Doesn't matter. figure out what the javascript would be?I've tried this but it doesn't work.document.getElementsByTagName("a") = alert("hello");
I accidentally damaged my slide show today and cant work out how to fix it. If you go to [URL] its on the home page. I had only links showing so I added the <ul id="slideshow"> tag and now I have the box coming up but its just blank.
I am having some issues running some ads coming from a database not showing up on my page it doesnt show anything at all im not sure what i have done wrong?i cud have it statically written in but it would be easier if i did it that way of getting the urls stored in a database.this is my php code along with javascript code inside my php code.
PHP Code: include("dbconnect.php"); $rQ="SELECT * FROM banner";
I'm working on developing an RSS/RDF/Atom Parser in JavaScript. I've already successfully implemented complete support for RSS 0.9x and 2.0. So far, so good. However, I've run into two minor problems. One is mentioned here, and one is in another post.
The issue that I'm coming across is the case-sensitivity of getElementsByTagName() when parsing standard RSS (XML) tags.
Danny Goodman's JavaScript Bible says that the tag name string that gets passed as the parameter in getElementsByTagName() is case-insensitive. However, this is speaking in terms of HTML and the HTML DOM. I'm working with XML, and getElementsByTagName is handling the XML tags as being case-sensitive.
Can someone suggest a way around this? Can a regular expression be used as the parameter? If so, what would the syntax be (as I'm not very familiar with regex)? For example, I want a <textinput> tag to be handled the same as <textInput> (which is the correct syntax).
