Array Length Not Working In Safari?

Jun 8, 2009

The problem is that it keeps returning a value of 0 every loop. When tested in Internet Explorer, FireFox and Google Chrome, it works just fine, returning values as it should (in this case the values of 32, 36, 35, 36). However, like i said, Safri returns 0, 0, 0, 0.

Crazy thing is, before it calls the checkArray() function, i check to make sure its sending the correct number and it does, so its something to do with the .length part since i did a check on that and that's where its coming up with the 0's.

var aryItems = new Array();
function add2Array(theName){aryItems[aryItems.length] = theName;}
function checkArray(theName){
for ( var z=0, len = aryItems.length; z < len; ++z ){

Get The Length Of String Function Not Working

Aug 16, 2010

i used the String.length(string) function in javascript to get the length of string but nothing happened. It doesn't give me a value when i tried to view the result using an alert function. Actually, this kind of problem does not only exist with the length function, it's also the same with the trim(). I have not tried using other functions but perhaps it won't also work. What could be the possible reason for this?

JQuery :: Get Tagname From Event?

Jul 14, 2009

I have a function that operates on left and right arrow keypress, but I want to temporarily "return true" if they're pressed while an input has focus.One way I thought of was to check the tagname of the event? The other way is to check the length of the input:focus array, but I reckon that'd be slower?[code]Is it possible to:

a) filter the document so that input fields are avoided
b) return true based on a check on e's tag name (help required)

JQuery :: Using Prop() To Set TagName?

Sep 2, 2011

From the current documentation about prop(): The .prop() method is a convenient way to set the value of properties—especially when setting multiple properties, using values returned by a function, or setting values on multiple elements at once. It should be used when setting selectedIndex, tagName, nodeName, nodeType, ownerDocument, defaultChecked, or defaultSelected. Since jQuery 1.6, these properties can no longer be set with the .attr() method. They do not have corresponding attributes and are only properties. On reading this, I was fascinated by the idea that I could use jQuery to instantly change one tag into anotherwith .prop("tagName","newtag"). But it doesn't seem to work. Runnin

DHTML Events Not Working In IE But Working In Firefox And Chrome?

May 10, 2010

I am working on a Javascript application and i am facing a strange behavior of the application in IE. I am creating a table at runtime using DHTML and registering event for the table row click. When i deploy this application on web server and browse the application, the events fires in firefox and chrome but in IE the events are not fired. If i browse the application from the server with localhost, the application triggers the events and fails when i use machine name.

The following is the source code:

GetElementsByTagName 'n Such

Jul 23, 2005

OK, so let's say, for example, I have a bit of HTML that looks like
this:

<td class="regular1b" valign="top">
<a href="notfound.html"><span class="list5"><b>Lecture
V</b></span></a>
</td>

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.

DOM GetElementsByTagName

Jan 12, 2004

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.

ie.
<customer id="1234" name="Mr Dodd">
<purchase po="1" value="3.00"/>
<purchase po="2" value="4.00"/>
<purchase po="3" value="5.00"/>
</customer>

I used getElementsByTagName("customer") to obtain the list of customers, but I'm having trouble referencing the child nodes ie. purchase.

Does getElementsByTagName("customer") also obtain the child nodes, or only the matching element?

GetElementsByTagName Is Not A Function?

Jun 30, 2006

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?)

Alternatives To GetElementsByTagName

Feb 27, 2006

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:
