Ok, I have been playing around with AJAX. But I have hit a snag.
I'm not too swift using javascript. I found a web site that has an
example of Google Suggest which is basically want I want to do. But
there is something wrong with my javascript. Hereis the javascript
in question:
<body MS_POSITIONING="GridLayout">
<form id="Form1" method="post" runat="server">
<input id="MyTextBox" type="text"
onkeypress="GetWords(event,this.value)">
script language="javascript">
function GetWords(pressevent,myVal)
{
var charCode = (pressevent.which)? pressevent.which :
(event.keyCode);
// Check for the enter key
if(charCode!= 13)
{
GoogleSelect.FillList(myVal,GetWords_CallBack)
if(charCode == 32)
{
// Put the value from the from the DIV into the TextBox
var word = document.getElementById("MyDiv").innerHTML;
document.getElementById("MyTextBox").value = word.substring
(0,word.length - 4);
}
}
}
function GetWords_CallBack(response)
{
if(response!=null)
{
document.getElementById("MyDiv").innerHTML = response.value;
}
}
</script>
</form>
</body>
On the line:
GoogleSelect.FillList(myVal,GetWords_CallBack). myVal seems to be
blank. If I hard code a value in here I can see it in my codebehind
function FillList.
In the following line, if I hardcode a value instead of using
this.value then it works. Here is the line:
<input id="MyTextBox" type="text" onkeypress="GetWords
(event,this.value)">
So it seems like there is something wrong here. this.value must be
incorrect. Can anyone see what I am doing wrong?
Thanks,
Bob
