Even in your example, “_txtMy” would still work, but you’re right. You’re less likely to run into “txtFirsttxtName” this way.

nice article by the way.

I had a site master page referencing jquery, then a sub-master, then a default.aspx. didn’t work; “Object expected” errors.

Added referenc jquery in the sub-master; everything works.
two things learned:
1) got a major clue on jQuery API (thk U mark!)
2) the a web form’s master page needs to have a reference to jQuery, not the master’s master (if such is the case in your website).

Too keep it straight in my head, I usually prefix my variable names with $ so I know it is a jQuery object and _not_ a DOM object.

var $myDiv = $(“#divTest”);
var $myTextbox = $(“input[id$='txtTest']“);

It is more obvious to me that I need to call methods on the jQuery API.

$myDiv.text($myTextbox.val());

All the calls off the jQuery objects are all from the API. http://docs.jquery.com/ is your best friend.

FYI ~ Since I give all my controls a unique ID (and I don’t use js yet on gridview controls, I’m gonna avoid using the underscore (for the time being).

$(“input[ID$='txtTest']“);
$(“input[ID$='txtTest']“).text;

One would assume I need to do something other than merely referencing it. So, tried all these and they fail with “object expected”:

$(“divTest”).text = $(“input[ID$='txtTest']“).text;
$(“#divTest”).text = $(“input[ID$='txtTest']“).text;
$(“.divTest”).text = $(“input[ID$='txtTest']“).text;
$(“input[ID$='divTest']“).text = $(“input[ID$='txtTest']“).text;

As already noted: I’m clueless in the northwest. One would think it would (and should) ‘just work’ .. ?!

For example, you won’t be able to do myTextBox.value, you’ll need to do myTextbox.Val(). See http://docs.jquery.com/Attributes/val

function SetLabel() {
//var sourceID = $(”#lblTest”);
//var targetID = $(”#txtTest”);
var a = “breakpoint”;
var myDiv = $get(”divTest”);
var myTextbox = $get(””);
myDiv.innerHTML = myTextbox.value;
}

$(“input[ID$='_txtTest']“);

This would find every HTML Input element that has an ID that ends with “_txtTest”. Hopefully there is only one, but if there are more, it will find all of them. You’ll either need to be more specific or give it a reference point.

My control:
[div id="divTest"]
This is a test.
[/div]
[asp:TextBox ID="txtTest" runat="server" Text="Changed to this new value #2." /]
[asp:Button ID="btnTest" runat="server" Text="Update Label" CausesValidation="false" OnClientClick="return SetLabel();" /]

My control:

This is a test.

=====
All the js function SetLabel() does is change the div to the value in the text box.
This is the *ONLY* method that works:

function SetLabel() {
//var sourceID = $(“#lblTest”);
//var targetID = $(“#txtTest”);

var a = “breakpoint”;
var myDiv = $get(“divTest”).text;
var myTextbox = $get(“”);
myDiv.innerHTML = myTextbox.value;
}

===========
C’mon, people; with the above stuff, I get NO access to the jQuery features for these objects.

Your method of using the underscore and then using the EndsWith (having changed the ID of my textbox control to “_txtTest”) would be:

$(“input[ID$='_txtTest']);

==> Where is the ending double-quote?
All I get is “unterminated string constant” in VS2008 javascript.
——
At this juncture, I have not been able to successfully employ jQuery after nearly 2 weeks of research, reading, trying this, trying that. All I freakin’ wanna do is take a stupid textbox and use it’s value to change the value of a div area.
Y’know, start small, then onto larger concepts.
BTW: WinXPPro_SP3, VS2008_SP1, ASP.Net 3.5, jQuery 1.3.2 w/ the vsdoc file, no master page, no fancy extra plugins, just a basic website with Default.aspx.

I gotta admit that I guess I’m *totally clueless” in any of this.
