Miscellaneous Resources


In mygame_mygame.tpl (the border is not required):

<div id="my_expandable" style="border: 1px solid black">
    <a href="#" id="my_click_to_toggle" class="expandabletoggle expandablearrow">
        <div class="icon20"></div>
    <div id="my_hidden_content" class="expandablecontent">
        Here's the hidden content

In mygame.js:

this.expanded = new ebg.expandablesection();
this.expanded.create(this, "my_expandable");
this.expanded.expand();   // show
this.expanded.collapse(); // hide
this.expanded.toggle();   // switch show/hide


Helper Code

This doesn't appear to be part of the BGA framework, but might make creating the above code easer and more readable.

In mygame_mygame.tpl:

var jstpl_expandablesection = '\
    <div id="${id}">\
        <a href="#" id="toggle_${id}" class="expandabletoggle expandablearrow">\
            <div class="icon20"></div>\
        <div id="content_${id}" class="expandablecontent">\

In mygame.js:

placeExpandableSection: function(parent_id, id, content) {
   html = this.format_block('jstpl_expandablesection', { id: id, content: content });, parent_id);
