django jquery toggle in form from model

问题

I was wondering if I could get some guidance using jquery in django.

I have a form from model in which I would like to display certain form fields based on a check box being checked or unchecked. Could also be done using a button. I am already using Jquery datepicker and timepicker in the form which works fine. Jquery toggle is here http://api.jquery.com/toggle/. I can get it work elsewhere, just not inside the form.

Here is a some template code where 'e' is the form from model being passed in, the datepicker code included as a quide for how toggle should work, and toggle code using a button to toggle. Thanks in advance.

回答1:

Try putting the jQuery event code inside an onload function, otherwise the form elements won't exist yet in the dom and there is nothing for jQuery to query yet.

$(document).ready(function() {
    $("#id_allday").click(function () {
        $('#toggle').toggle("slow");
    })
}

Also, you may want to bind to change instead of click incase someone toggles the input with the spacebar instead of the mouse button.
