building on my last question jQuery getting values from multiple selects together
I have the select list like:
<select name="access" class="change" id="staff_off" runat="server">
<option value="8192">Off</option>
<option value="8192">On</option>
</select>
And I basically want to add or subtract the value of the options if it's off, subtract if it's on add it. It's going to be stored in a cookie (it uses bitwise)
The jquery I have is:
<script>
$(document).ready(function(){
var currentAccess = $.cookie("access");
})
$("select").change(function () {
var currentText = $(this).text()
var value = $(this).val()
$.cookie("access", value, { expires: 24 });
alert(currentText);
alert( $.cookie("access") );
})
</script>
I'll do the addition in the change function. The thing I can't work out is how to get the text of the select to do an if statement (so if it's yes, add the value, if it's no, subtract the value)

If you're looking for the inner text of the selected <option> element, you can use the :selected selector to match it, then call the text() method:
ReplyDeletevar currentText = $(this).find(":selected").text();
Or, alternatively:
var currentText = $(":selected", this).text();
To get the text of the selected item:
ReplyDeletevar value = $("#staff_off :selected").text();
I'd also suggest (if you're using HTML5) that using the data-x attribute to store the flag whether to add or subtract the value would be more semantic. Like this:
<select name="access" class="change" id="staff_off" runat="server">
<option value="8192" data-factor="-1">Off</option>
<option value="8192" data-factor="1">On</option>
</select>
Then to get your final value to apply to the total you simply multiply the value by the data-factor attribute.
You can use this $("#staff_off").find("option:selected").html();
