I don't think you need underscore for that just regular ole js - hope this is what you are looking for

var data =  [
        {
            "text":"one","siteid":"1","chid":"default","userid":"8","time":1374156747
        },
        {
            "text":"two","siteid":"1","chid":"default","userid":"7","time":1374156735
        }
    ];

var userid = "userid"
var filterparams = {userid:'7', chid: 'default'};
var index;
for (i=0; i < data.length; i++) {
    for (prop in data[i]) {
        if ((prop === userid) && (data[i]['userid'] === filterparams.userid)) {
            index = i
        }
    }
}

alert(index);
