javascript - 使用JS获取数组内对象的索引

Question

我正在制作一个从数组中获取对象的 js 代码。我只想有一个脚本获取对象索引并将其打印在 html 页面上。我尝试了很多不同的东西，但没有任何效果。例如，假设第一个 {} 为 0，然后第二个速率为 3.3 的为 1...这是一个 jsfiddle:https://jsfiddle.net/76e40vqg/1/

var data = [{"image":"link1","name":"Name1","address":"Address1","rate":"4.4"},{"image":"link2","name":"Name2","address":"Address2","rate":"3.3"},{"image":"link3","name":"Name3","address":"Address3","rate":"3.2"}
];
var restoName = [];
for(i = 0; i < data.length; i++){    
    if(restoName.indexOf(data[i].name) === -1){
        restoName.push(data[i].name);        
    }        
}

var restoAddress = [];
for(i = 0; i < data.length; i++){    
    if(restoAddress.indexOf(data[i].address) === -1){
        restoAddress.push(data[i].address);        
    }        
}

var restoRate = [];
for(i = 0; i < data.length; i++){    
    if(restoRate.indexOf(data[i].rate) === -1){
        restoRate.push(data[i].rate);        
    }        
}

var restoImage = [];
for(i = 0; i < data.length; i++){    
    if(restoImage.indexOf(data[i].image) === -1){
        restoImage.push(data[i].image);
    }        
}

for(i = 0; i < restoName.length; i++){
document.getElementById('output').innerHTML += "Image : <a href='" + restoImage[i] + "'><div class='thumb' style='background-image:" + 'url("' + restoImage[i] + '");' + "'></div></a><br>" + "Name : " + restoName[i] + "<br>" + "Address : " + restoAddress[i] + "<br>" + "Rate : " + restoRate[i] + "<br>" + "Index" + "<br><hr>";
  }

谢谢

我想你不见了..."Index" + i +"<br>...
