按键获取Javascript对象值 [英] Get Javascript object value by key

问题描述

var Array = [];

{'DateOfBirth' : '06/11/1978',
 'Phone' : '770-786',
 'Email' : '[e-mail]' ,
 'Ethnicity' : 'Declined' ,
 'Race' : 'OtherRace' , }

我需要在这里访问'Race'..我该怎么做...它是一个包含这些数据的数组......

I need to access the 'Race' here.. how can i do it... Its an array which holds this data...

推荐答案

这不是一个数组，它是一个对象。你想做类似的事情：

Thats not an array, its an object. You want to do something like:

var myObject = {
  'DateOfBirth' : '06/11/1978',
  'Phone' : '770-786',
  'Email' : '[e-mail]' ,
  'Ethnicity' : 'Declined' ,
  'Race' : 'OtherRace'
};

// To get the value:
var race = myObject.Race;

如果对象位于数组 var ArrayValues = [{object}， {object}，...]; 然后常规数组访问器将起作用：

If the Objects are inside an array var ArrayValues = [{object}, {object}, ...]; then regular array accessors will work:

var raceName = ArrayValues [0 ] .Race;

或者，如果你想循环这些值：

Or, if you want to loop over the values:

for (var i = 0; i < ArrayValues.length; i++) {
    var raceName = ArrayValues[i].Race;
}
