javascript - Find index in array of objects -


i find index in array. positions in array objects, , want filter on properties. know keys want filter , values. problem index of array meets criteria.

for made code filter data , gives me object data, not index of array.

var data =  [         {             "text":"one","siteid":"1","chid":"default","userid":"8","time":1374156747         },         {             "text":"two","siteid":"1","chid":"default","userid":"7","time":1374156735         }     ];  var filterparams = {userid:'7', chid: 'default'};  function getindexofarray(thelist, props){     var pnames = _.keys(props)     return _.find(thelist, function(obj){         return _.all(pnames, function(pname){return obj[pname] == props[pname]})     })};  var check = getindexofarray(data, filterparams ); // want '2', not key => val

here thefiddle hope helps you

 for(var intindex=0;intindex < data.length; intindex++){   eachobj = data[intindex]; var flag = true;  (var k in filterparams) {      if (eachobj.hasownproperty(k)) {         if(eachobj[k].tostring() != filterparams[k].tostring()){            flag = false;         }     } } if(flag){        alert(intindex); }

}
