Updating a select onclick
}) My problem is that the change event does not trigger on $('#'+select_id).trigger("onchange"); but on $('#'+select_id).trigger("change"); Do you know why?
On this page we show how to use Java Script to handle individual checkboxes and groups of checkboxes onclick.
Mainly because it takes the traditional graph that we know, love and have been familiar with since childhood and adds in an aspect that that has been missing for most of your life. Seeing information represented in a graphical way allows leaps of understanding that are difficult or impossible to achieve from raw data.
We use the following form to demonstrate an alternative approach: To obtain references to the checkboxes in the form, we enclose the checkboxes in a container with an ID.
We get a reference to that container using its ID, then use function to the onclick property of each checkbox.
As explained in Assigning Functions to Event Handler Properties, a function assigned to an event handler property of an object has access to that object inside the function via the function is used on the resulting value before placing it in the total text box.
Another example combines the above with radio buttons for a more complete pizza order form.
