getpublic
Dynamically look up a property on an object. The second argument to {{get}} should have a string value, although it can be bound.
For example, these two usages are equivilent:
1 2 | {{person.height}}{{get person "height"}} |
If there were several facts about a person, the {{get}} helper can dynamically pick one:
1 | {{get person factName}} |
For a more complex example, this template would allow the user to switch between showing the user's height and weight with a click:
1 2 3 | {{get person factName}}<button {{action (mut factName) "height"}}>Show height</button><button {{action (mut factName) "weight"}}>Show weight</button> |
The {{get}} helper can also respect mutable values itself. For example:
1 2 3 | {{input value=(mut (get person factName)) type="text"}}<button {{action (mut factName) "height"}}>Show height</button><button {{action (mut factName) "weight"}}>Show weight</button> |
Would allow the user to swap what fact is being displayed, and also edit that fact via a two-way mutable binding.
