Please debug javascript in VS.

this error means $get('tx_name') is a null object

i used the above code & getting this error

Microsoft JScript runtime error: 'undefined' is null or not an object

at line

var x=$get('tx_name').value = dd.substring(0, dd.indexOf('|'));

in the below line

var dd = $find("autoCompleteBehavior1").get_completionList().childNodes[index]._value;

i get the value of dd as undefined

this is my full code

function pageLoad()
{
$find("autoCompleteBehavior1").add_itemSelected(setValue);
}

function setValue()
{

var index = $find("autoCompleteBehavior1")._selectIndex;
    var dd = $find("autoCompleteBehavior1").get_completionList().childNodes[index]._value;
    alert(dd)
    var x=$get('tx_name').value = dd.substring(0, dd.indexOf('|'));
alert(x)

}

I am not getting whats not actually working for you . the code snippet which I have provided , I have been using it in many places and it has even worked for many people here in this forum. Following is how I generally use it :-

var index = $find("<behaviour id of the autocomplete extender>")._selectIndex;
var dd = $find("<behaviour id of the autocomplete extender>").get_completionList().childNodes[index]._value;
$get('<id of the textbox>').value = dd.substring(0, dd.indexOf('|'));

Please cross check whether you are getting values form the server side code properly or not . May be there you will find something which might be causing the problem.

with the above i am getting "undefined "

i used

var

dd =$find("autoCompleteBehavior1").get_element().value = eventArgs.get_text().split(":")[0] ;

i get the value selected

i even get the value on the server side

now my prblm is with the value which i get after selection i need to get other related data of that selected value

so i use the value frm server side in the query

but i am not able to use it in text changed event of textbox

& secondaly after the selection is done i need the tab to be automiticaly moved to next control

svibuk:
function pageLoad()

{

$find("autoCompleteBehavior1").add_itemSelected(onItemSelected);

}

Rather than setting it ion pageLoad function set this attribute directly in decleration of the control ie in markup.Where are you getting the error ie in which line ? If things are proper then alret(dd) --> will throw an alert message showing the content of the selected value.

Hi,

Firstly, you can use $find('behaviorID').get_element() to get the instance of Textbox.

In your code, please use

var dd = $find("autoCompleteBehavior1").get_completionList().childNodes[index]._value;

instead of

var dd = $find("autoCompleteExtender1").get_completionList().childNodes[index]._value;

You used incorrect behaviorID.

i tried using aboce code

but getting

Microsoft JScript runtime error: 'null' is null or not an object

the follwoing is teh javascript on client side

$find(

function pageLoad()

{

$find("autoCompleteBehavior1").add_itemSelected(onItemSelected);

}

function onItemSelected(evt) {

var index = $find("autoCompleteBehavior1")._selectIndex;

alert(index)

var dd = $find("autoCompleteExtender1").get_completionList().childNodes[index]._value;

alert(dd)

i get the index butnot the value

Assign a client side event handler for the item selected eevent and then in that handler you can retrive the selecetd value with the following code :-

function itemSelected(evt) {
var index = $find("<behaviour id of the autocomplete extender>")._selectIndex;
var dd = $find("behVendorList").get_completionList().childNodes[index]._value;

//here you can use the above variable dd and then assign value to respective textbox
}

getting selected value from autoCompleteExtender

svibuk — Sat, 04 Jul 2009 06:16:02 GMT

function pageLoad(){
            $find("autoCompleteBehavior1").add_itemSelected(onItemSelected);
        }

        function onItemSelected(){
            //you can add some code here to send a postback.
          alert("hello")
        }

using above oon the client side i get the messgae from alert
but i need the select value from the autocompleteextender in the textbox
so that i culd assign that value to a hidden field & use that in the server side query to get the corresponsing details

i am not able to use the normal javascript code ie document.getElementById('autoCompleteExtender1').value or even with the textbox
