Hi all.

I have a question about javascript.

I have to use the post function in the javascript codes located in the html file header to send data in the queryString variable to the autocom.jsp file located in the local server and then get data back from my local database using the callback function, function(data) { }.

My problem is that when I input c in the input field of the html page, testing ok is displayed on the webpage, even when in my database I do not have a data in the last name column (called last in the database) which start by letter c. This should never have occurred since data.length >0 is not true in this particular case.

Could somebody please help me with this issue?

Thanks

The html file is search.html below:

<html>

<head>

</head>

<body>

<form method="post" action="search.jsp" onsubmit="return checkSubmit (this);">
Enter Last Name: <input type="text" name="last" value="" id="suggestions" id="autoSuggestionsList" onkeyup="lookup(this.value);" /><br>
<input type="submit" value="Submit">
</form>

</body>

</html>

Below is the autocom.jsp file:

Could you show us the version of your code with the debugging statements demonstrating that data.length is equal to zero inside that if-statement? Or alternatively, could you explain how you determined that data.length was equal to zero?
