Question

I wanted to know how can I detect the checkbox values and selectbox entered in my registration form.
This is the select:

<p><label for="favorite">שחקן המועדף עליך</label>
<select name = "favor">
<option> </option>
<option value="פרקינס">דורון פרקינס</option>
<option value="סופוקליס שחורציאניטיס">סופוקליס שחורציאניטיס</option>
<option value="עומרי כספי">עומרי כספי</option>
<option value="דייויד בלו">דייויד בלו</option>
</select></p>

and that’s the checkbox:

 <p><label for="checkbox">אופנוע</label><input type="checkbox" name="bike" id="bike" value="bike" /> </p>
    <p><label for="checkbox">מכונית</label><input type="checkbox" name="car" id="car" value="car" /> </p>

How can I get the selected option and the selected boxes in the checkbox on clientside?

If anything is needed to explain let me know please,
Thank you!

Edit: I will explain myself a bit more, I’m having a registration form, which has checkboxes and tags. I want to know what the client chose and insert it into my SQL DB, I need to know how to get what the client pressed, like on what box he ticked V, what option he chose.

If you want to get this client-side, you can use jQuery to harvest the results:

$("#bike").is(':checked');

and

$("option:selected","#favor").val();

Note that your select doesn’t have an id, only a name, so you’ll also need to change it to this:

<select name="favor" id="favor">

If you want to get this server-side, you can use something like this:

string s = Request.Form["bike"];
if ( !string.IsNullOrEmpty(s) ) {

Note that most browsers will send a post value if the checkbox is checked with a value of “checked” or “true”, and not send it if it isn’t checked.

Even better is to replace these html tags with asp.net webforms tags like so:

<asp:CheckBox id="bike" runat="server" ... />

That way you can do this server-side:

bool checked = this.bike.Checked;
