Populate <strong>Finally!</strong> 介绍
Populate a form or an element’s child elements using a JSON object.
This plugin supports full PHP naming and deep data structures, as well as
checkbox arrays and other non-standard UI controls. The plugin can be used as
part of your AJAX toolkit, or for separating server-side code from HTML by
populating a form after the page has loaded eg:
$('form').populate({'text':'text', 'radio':1})
and not inline as the page is processed, such as:
<input type="text" name="text" id="text" value="<?php echo $text; ?>" /> <input type="radio" name="radio" id="radio-1" checked="<?php echo $val == 1; ?>" /> <input type="radio" name="radio" id="radio-2" checked="<?php echo $val == 2; ?>" />
Non-form elements
You can also populate non-form controls such as
and an identifying attribute (defaults to id):
$('div').populate({'text-1':'text', 'text-2':'More text'})
This can be useful when you want to show the results of a database call, but
don’t want the text to be editable.
Usage
Just include the PHP JSON class, PHP helper function and of course Populate at
the top of your page, and a PHP snippet such as this the bottom:
<?php populate('form', $data); ?/>
Which will output something meaningful like this:
$('form').populate({'text':'text', 'radio':1})
Live Demo
Finally!
I’ve now FINALLY put up a full set of instructions and a working demo, with
examples of:
- Populating a simple form, using string variable types for textfields, radiobuttons, dropdowns and checkboxes
- Populating a complex form, using array variable types for checkbox arrays and multi-list boxes
- Populating a hierarchical form, using hierarchical JSON data
