Just wondering if anyone knows why I can't get both key/values within a 'where' to be dynamic? I can do the value through a variable, that works perfectly, but I can't seem to get the key to run off a variable at all.
My fiddle is here: http://jsfiddle.net/leapin_leprechaun/eyw6295q/ the code I'm trying to get working is below.
I'm new to backbone so there's a chance this is something you can't do and I just don't know about it yet!
var newCollection = function(myCollection,prop,val){
alert('myprop: ' + prop);
alert('val: ' + val);
var results = myCollection.where({
//prop: val this doesn't work even if I put a string above it to make sure the value coming through is fine
//prop: "Glasnevin" //this doesn't work
"location" : val //this works
});
var filteredCollection = new Backbone.Collection(results);
var newMatchesModelView = new MatchesModelView({collection: filteredCollection });
$("#allMatches").html(newMatchesModelView.render().el);
}
Thanks for your time
Your code does not work because the key "prop" is always interpreted literally, as a string. So, you search by {"prop": val} not by {"location": val}. There are couple ways how to solve this problem
var where = {};
where[prop] = val;
var results = myCollection.where(where);
var results = myCollection.where(_.object([prop], [val]));
