将javascript函数添加到foodcrud添加或编辑表单

Question

Is it possible to add a javascript function to the add/edit forms of grocery_CRUD?

Eg As a user is typing in a particular field when adding or editing a record I want to execute a javascript on the keydown event.

If so, how?

Answer 1

It is possible. For example, you call the view like this:

$this->load->view('grocery_crud_view', $output);

In the beginning of the view (grocery_crud_view.php), you can add any javascript

<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
<script type="text/javascrpt">
    $("#field-code").keyup(function(){
       alert("there is a keyup");
    });
</script>
<?php
// The rest of default php code
?>

Most of the id of the grocery-CRUD view (if you use flexigrid theme) would be something like this : "field-your_field_name" You can inspect with firebug or google-chrome developer tools to ensure it.
