getElementById doesn't seem to work

[Lit]

use this

var toResumeText = document.getElementById('<%=objResumeText.ClientID%>');



DO NOT USE THIS

_ctl0_ResumeDisplay_objResumeText.ClientID

_ctl0_ResumeDisplay_objResumeText is the ClientID



Lit

The asp.net line is:

<asp:Label ID="objResumeText" runat="server"/>

in the View Source it is:

<span id="_ctl0_ResumeDisplay_objResumeText"></span>

Could the error be because the objResumeText is in a User control
(ResumeDisplay)?

I assume that the problem is the User Controls, because I created a Label
on my main page with id of "theLabel" and this worked fine:

var toResumeText = document.getElementById('<%=theLabel.ClientID%>');

Maybe the problem is related to the fact that you cannot even comment
problem line without getting an error which makes no sense to me.

I tried:

// var toResumeText =
document.forms[0].getElementById('<%=_ctl0_ResumeDisplay_objResumeText.ClientID%>');

and

/* var toResumeText =
document.forms[0].getElementById('<%=_ctl0_ResumeDisplay_objResumeText.ClientID%>');
*/

Both still give me the error that _ctl0_ResumeDisplay_objResumeText
doesn't exist - which it does. But even if it didn't, the commenting out
should prevent the error. This is the first time I have not been able
comment a line out.

Thanks,

Tom

Thanks,

if the ServerSide ID of your Label is MyLabel123 then use
<%=MyLabel123.ClientID%> -- verify syntax

Make sure Label is runat="server"

as i said, you need to use the childNodes, and a span does not have a
type or name property.

var nodes = document.forms[0].childNodes;
for (var i=0; i < nodes.length; ++i)
{
alert("tag: " + node.tagName + " id: " + nodes.id);
}

or lookup the span by id.

var theBox = document.getElementById('<%=theBox.ClientId%>');

I tried that but it gives me an error:

Maybe the problem is related to the fact that you cannot even comment
problem line without getting an error which makes no sense to me.

I tried:

// var toResumeText =
document.forms[0].getElementById('<%=_ctl0_ResumeDisplay_objResumeText.ClientID%>');

and

/* var toResumeText =
document.forms[0].getElementById('<%=_ctl0_ResumeDisplay_objResumeText.ClientID%>');
*/

Both still give me the error that _ctl0_ResumeDisplay_objResumeText
doesn't exist - which it does.

Not sure about why that is exactly but, to answer your question about
commenting, you need to comment both the client-side *AND* server side
script e.g.

// var toResumeText =
document.forms[0].getElementById('<%//=_ctl0_ResumeDisplay_objResumeText.ClientID%>');

 

[tshad]

use this

var toResumeText = document.getElementById('<%=objResumeText.ClientID%>');

Didn't work in the .aspx page.

Just copied and pasted it in but I get the same error (except it now says
that objResumeText doesn't exist).

Here is the object in the .ascx page:

<tr bgcolor="#F3F3F3">
<td><p style="margin-left:10px"><asp:Label ID="objResumeText"
runat="server"/>
<br> <br>
</td>
</tr>

Here is the object in the View Source (after I take the line out so the page
loads correctly).

<tr bgcolor="#F3F3F3">
<td><p style="margin-left:10px"><span
id="_ctl0_ResumeDisplay_objResumeText"></span>
<br> <br>
</td>
</tr>

I am getting this error before the function is called as I have at least 3
alert statements before the getElementById statement.

It probably has something to do with the Javascript being in the .aspx page
and objResumeText being in the .ascx page that is being called by the .aspx
page.

But since this is being called onload in the <body> tag, I can't put the
Javascript in the .ascx file (I don't think).

The body tag is:

<body id="myBody" leftmargin="0" topmargin="0" marginwidth="0"
marginheight="0" runat="server">

and the onload is being set in the Page_Load function:

Sub Page_Load(sender as Object, e as EventArgs)
Dim thePage as String
myBody.Attributes.Add("onLoad","entry()")
Dim pageControl as Control

I finally got it to work by moving the script section over to the .ascx
(User Control) page. I wasn't sure it would work as I thought it may cough
up on the myBody.Attributes.Add("onLoad","entry()") statement in the .aspx
file since now the entry() function is in the .ascx file. I thought it may
say that entry() doesn't exist.

Apparently, that wasn't the case as it works now.

I think it is interesting that

var toResumeText =
document.getElementById('ctl0_ResumeDisplay_objResumeText');

works in the .aspx file and

var toResumeText = document.getElementById('<%=objResumeText.ClientID%>');

does not.

I am still confused why comments don't work in this case.

Thanks,

Tom

tshad,

This is wrong.
document.getElementById('<%=ctl0_ResumeDisplay_objResumeText.ClientID%>');

it looks like you are getting the ClientId on the clientId

<%=The_ID_Of_Your_Server_Control.ClientId%>

What is the ID of your Label

The asp.net line is:

<asp:Label ID="objResumeText" runat="server"/>

in the View Source it is:

<span id="_ctl0_ResumeDisplay_objResumeText"></span>

Could the error be because the objResumeText is in a User control

Maybe the problem is related to the fact that you cannot even comment

I tried:

// var toResumeText =
document.forms[0].getElementById('<%=_ctl0_ResumeDisplay_objResumeText.ClientID%>');

and

/* var toResumeText =

*/

Both still give me the error that _ctl0_ResumeDisplay_objResumeText
doesn't exist - which it does.

Not sure about why that is exactly but, to answer your question about
commenting, you need to comment both the client-side *AND* server side
script e.g.

// var toResumeText =
document.forms[0].getElementById('<%//=_ctl0_ResumeDisplay_objResumeText.ClientID%>');

Really?

Why is that? Comments are supposed to be ignored. Lines that are commented
by /* */ could span 20 lines. But if this line is in the commented lines
it will get the error.

What other things cause this problem with comments?

Thanks,

Tom

I am looking for 2 objects on my opener page and 2 from my current
page. I can find all the objects except the
'ctl0_ResumeDisplay_objResumeText' which is the only object that is
an asp:Label.

This code worked fine except that it didn't find Label objects - it
found the other 3.

This error happened when I added the <%=...%> format.

The interesting thing is that I get the error even when I comment out
the new line and the error is on the commented out line????

I would delete the label and recreate it.
Something is strange. I don't know why it does not work.

You're right.

I deleted and recreated the Label and it worked. I think I may have been
missing the "__" at the beginning of the ID.

I did find that the following getElementByID format is the one you have to
use if the control is on a different page. This means you would need to
look at the View Source to find out the actual ID. This is what
<%=objResumeText.ClientID%> does for you.

document.getElementById('_ctl0_ResumeDisplay_objResumeText');

The following getElementByID is better since you don't need to know what the
ID will render to. But the control MUST be on the same page or User
Control. If you are using multiple controls, this wouldn't work. You will
get an "objResumeText" does not exist - even though it will on the full page
after rendering.

document.getElementById('<%=objResumeText.ClientID%>');

Thanks for all the help,

Tom

use this

var toResumeText =
document.getElementById('<%=objResumeText.ClientID%>');

Didn't work in the .aspx page.

Just copied and pasted it in but I get the same error (except it now says
that objResumeText doesn't exist).

Here is the object in the .ascx page:

<tr bgcolor="#F3F3F3">
<td><p style="margin-left:10px"><asp:Label ID="objResumeText"
runat="server"/>
<br> <br>
</td>
</tr>

Here is the object in the View Source (after I take the line out so the
page loads correctly).

<tr bgcolor="#F3F3F3">
<td><p style="margin-left:10px"><span
id="_ctl0_ResumeDisplay_objResumeText"></span>
<br> <br>
</td>
</tr>

I am getting this error before the function is called as I have at least
3 alert statements before the getElementById statement.

It probably has something to do with the Javascript being in the .aspx
page and objResumeText being in the .ascx page that is being called by
the .aspx page.

But since this is being called onload in the <body> tag, I can't put the
Javascript in the .ascx file (I don't think).

The body tag is:

<body id="myBody" leftmargin="0" topmargin="0" marginwidth="0"
marginheight="0" runat="server">

and the onload is being set in the Page_Load function:

Sub Page_Load(sender as Object, e as EventArgs)
Dim thePage as String
myBody.Attributes.Add("onLoad","entry()")
Dim pageControl as Control

I finally got it to work by moving the script section over to the .ascx
(User Control) page. I wasn't sure it would work as I thought it may
cough up on the myBody.Attributes.Add("onLoad","entry()") statement in
the .aspx file since now the entry() function is in the .ascx file. I
thought it may say that entry() doesn't exist.

Apparently, that wasn't the case as it works now.

I think it is interesting that

var toResumeText =
document.getElementById('ctl0_ResumeDisplay_objResumeText');

works in the .aspx file and

var toResumeText =
document.getElementById('<%=objResumeText.ClientID%>');

does not.

I am still confused why comments don't work in this case.

Thanks,

Tom

DO NOT USE THIS

_ctl0_ResumeDisplay_objResumeText.ClientID

_ctl0_ResumeDisplay_objResumeText is the ClientID



Lit



tshad,

This is wrong.
document.getElementById('<%=ctl0_ResumeDisplay_objResumeText.ClientID%>');

it looks like you are getting the ClientId on the clientId

<%=The_ID_Of_Your_Server_Control.ClientId%>

What is the ID of your Label

The asp.net line is:

<asp:Label ID="objResumeText" runat="server"/>

in the View Source it is:

<span id="_ctl0_ResumeDisplay_objResumeText"></span>

Could the error be because the objResumeText is in a User control
(ResumeDisplay)?

I assume that the problem is the User Controls, because I created a
Label on my main page with id of "theLabel" and this worked fine:

var toResumeText = document.getElementById('<%=theLabel.ClientID%>');

Maybe the problem is related to the fact that you cannot even comment
problem line without getting an error which makes no sense to me.

I tried:

// var toResumeText =
document.forms[0].getElementById('<%=_ctl0_ResumeDisplay_objResumeText.ClientID%>');

and

/* var toResumeText =
document.forms[0].getElementById('<%=_ctl0_ResumeDisplay_objResumeText.ClientID%>');
*/

Both still give me the error that _ctl0_ResumeDisplay_objResumeText
doesn't exist - which it does. But even if it didn't, the commenting
out should prevent the error. This is the first time I have not been
able comment a line out.

Thanks,

Tom




Thanks,

Tom

if the ServerSide ID of your Label is MyLabel123 then use
<%=MyLabel123.ClientID%> -- verify syntax

Make sure Label is runat="server"

Lit




as i said, you need to use the childNodes, and a span does not have
a type or name property.

var nodes = document.forms[0].childNodes;
for (var i=0; i < nodes.length; ++i)
{
alert("tag: " + node.tagName + " id: " + nodes.id);
}

or lookup the span by id.

var theBox = document.getElementById('<%=theBox.ClientId%>');

I tried that but it gives me an error:

Not sure about why that is exactly but, to answer your question about
commenting, you need to comment both the client-side *AND* server side
script e.g.

// var toResumeText =
document.forms[0].getElementById('<%//=_ctl0_ResumeDisplay_objResumeText.ClientID%>');

Really?

Why is that? Comments are supposed to be ignored. Lines that are
commented by /* */ could span 20 lines.

<%=...%> basically say "inject a string literal into the HTML markup" - it
has no concept of whether the string that it's injecting resides within a
commented block of JavaScript or not...

But if this line is in the commented lines it will get the error.

That's right - so comment it out and you won't...

I'm not sure what "problem" you're talking about - this is totally expected
behaviour...

 

[tshad]

I'm not sure what "problem" you're talking about - this is totally
expected behaviour...

It may be expected behavior to you, but I had never heard of it. I have
been programming for years and a comment is a comment. Anything inside a
comment tag, regardless of language, is ignored.

Apparently that is not the case with the <%=...%> construct.

What you are saying is that comments are only partially comments. If they
have certain characters in them, then they aren't???

You can normally, in other languages (of course HTML is not really a
language), comment whole sections of code for explanations, debugging or
just to be able to use later.
