在对象数组中查找索引

Question

我想在数组中找到索引.数组中的位置是对象,我想过滤它们的属性.我知道我想要过滤哪些键及其值.问题是获得符合标准的数组索引.

现在我制作了代码来过滤数据并给我回溯对象数据,但没有给出数组索引.

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 to get '2', not key => val

Answer 1

使用Lo-Dash代替下划线,您可以非常轻松地使用它_.findIndex().

var index = _.findIndex(array, { userid: '7', chid: 'default' })

Answer 2

这是小提琴希望它能帮助你

 for(var intIndex=0;intIndex < data.length; intIndex++){
  eachobj = data[intIndex];
var flag = true;
 for (var k in filterparams) {

    if (eachobj.hasOwnProperty(k)) {
        if(eachobj[k].toString() != filterparams[k].toString()){
           flag = false;
        }
    }
}
if(flag){
       alert(intIndex);
}

}
