array.filter(function(item, indx, arr){ return(item.hello === 'stevie'); })[0];

小心[0]。

在安东尼奥·拉古纳的回答中使用reduce是恰当的。

抱歉这么简短……

var idx = myArray.reduce( function( cur, val, index ){

    if( val.hello === "stevie" && cur === -1 ) {
        return index;
    }
    return cur;

}, -1 );

短暂的

myArray.indexOf('stevie','hello')

用例:

  /*****NORMAL****/  
[2,4,5].indexOf(4) ;//OUTPUT 1
 /****COMPLEX*****/
 [{slm:2},{slm:4},{slm:5}].indexOf(4,'slm');//OUTPUT 1
 //OR
 [{slm:2},{slm:4},{slm:5}].indexOf(4,function(e,i){
   return e.slm;
});//OUTPUT 1
/***MORE Complex**/
[{slm:{salat:2}},{slm:{salat:4}},{slm:{salat:5}}].indexOf(4,function(e,i){
   return e.slm.salat;
});//OUTPUT 1

火:

    Array.prototype.indexOfOld=Array.prototype.indexOf

    Array.prototype.indexOf=function(e,fn){
      if(!fn){return this.indexOfOld(e)}
      else{ 
       if(typeof fn ==='string'){var att=fn;fn=function(e){return e[att];}}
        return this.map(fn).indexOfOld(e);
      }
    };

var hello = {hello: "world",  foo: "bar"};
var qaz = {hello: "stevie", foo: "baz"};
var myArray = [];
myArray.push(hello,qaz);

function indexOfObject( arr, key, value   ) {
    var j = -1;
    var result = arr.some(function(obj, i) { 
        j++;
        return obj[key] == value;
    })

    if (!result) {
        return -1;
    } else {
        return j;
    };
}

alert(indexOfObject(myArray,"hello","world"));

这是在数组中查找对象索引的方法

    var myArray = [{  hello: 'world',
        foo: 'bar'
    },{
        hello: 'stevie',
        foo: 'baz'
    }];



    for (i = 0; i < myArray.length; i++) {
        if (myArray[i].hello === 'stevie') {
            alert('position: ' + i);
            return;
        }
    }

或者创建原型:

Array.prototype.indexOfObject = function arrayObjectIndexOf(property, value) {
    for (var i = 0, len = this.length; i < len; i++) {
        if (this[i][property] === value) return i;
    }
    return -1;
}

myArr.indexOfObject("name", "stevie");
