Question

I have drop down menu which i choose one item from it and then by using onblur event i can post the match detail into input text box. whenever i choose from the drop menu, the matched detail should posted into the input text box. In my example i will choose a specific industry field and the related questions should be appear in question1 and question2 input text box. Example is below:
var db = Database.Open("me");
var ind = Request["areagroup"];
var sqlq = "SELECT id,indName,question1,question2 from Industry where id = #0";
var data = db.Query(sqlq,ind);
<select name="areagroup" onblur="???? ">
<option value="0">General</option>
<option value="1">Services</option>
<option value="2">Basic Materials</option>
</select>
<label>Question 1</label><input type="text" name="q1" />
<br/>
<label>Question 2</label><input type="text" name="q2" />

I'm not sure of your target.
The code that follows populates the input fields when the dropdown loses its focus:
#{
var question1 = "";
var question2 = "";
if (IsPost)
{
if(Request["butt"] != "test"){
var db = Database.Open("me");
var ind = Request["areagroup"];
var sqlq = "SELECT id,indName,question1,question2 from Industry where id = #0";
var data = db.Query(sqlq,ind);
question1 = data.question1;
question2 = data.question2;
} else {
// If submit button is pressed
}
}
}
<form method="post">
<select name="areagroup" onblur="this.form.submit()">
<option value="0">General</option>
<option value="1">Services</option>
<option value="2">Basic Materials</option>
</select>
<br/ >
<label>Question 1</label><input type="text" name="q1" value="#question1" />
<br/>
<label>Question 2</label><input type="text" name="q2" value="#question2" />
<br/>
<input type="submit" name="butt" value="test" />
</form>
I have provided a submit button and an if statement inside the IsPost block to test if the form is submitted by the user.
In my opinion, a better solution is to use the onchange instead of the onblur event adding a dummy option to the dropdown (something like <option value="-1">--- Please select ---</option>).
