|
|
|
+ * Template code
|
|
|
+ *
|
|
|
+ * A template is just a JavaScript structure. An element is represented as:
|
|
|
+ *
|
|
|
+ * [tag_name, {attr_name:attr_value}, child1, child2]
|
|
|
+ *
|
|
|
+ * the children can either be strings (which act like text nodes), other templates or
|
|
|
+ * functions (see below)
|
|
|
+ *
|
|
|
+ * A text node is represented as
|
|
|
+ *
|
|
|
+ * ["{text}", value]
|
|
|
+ *
|
|
|
+ * String values have a simple substitution syntax; ${foo} represents a variable foo.
|
|
|
+ *
|
|
|
+ * It is possible to embed logic in templates by using a function in a place where a
|
|
|
+ * node would usually go. The function must either return part of a template or null.
|
|
|
+ *
|
|
|
+ * In cases where a set of nodes are required as output rather than a single node
|
|
|
+ * with children it is possible to just use a list
|
|
|
+ * [node1, node2, node3]
|
|
|
+ *
|
|
|
+ * Usage:
|
|
|
+ *
|
|
|
+ * render(template, substitutions) - take a template and an object mapping
|
|
|
+ * variable names to parameters and return either a DOM node or a list of DOM nodes
|
|
|
+ *
|
|
|
+ * substitute(template, substitutions) - take a template and variable mapping object,
|
|
|
+ * make the variable substitutions and return the substituted template
|
|

+ *
