给js对象赋值，赋值key

var pastResult = []; pastResult.push(feature.attributes.F_iID); pastResult.push(feature.attributes.F_sName); pastResult.push(feature.attributes.F_sAddress); 得到的结果是：想要把默认的0、1、2，改成F_iID、F_sName、F_sAd...

pastResult是数组，所以只能用0，1，2

// 用对象

var pastResult = {};

pastResult['F_iID'] = feature.attributes.F_iID;

pastResult['F_sName'] = feature.attributes.F_sName;

pastResult['F_sAddress'] = feature.attributes.F_sAddress;

alert(pastResult['F_iID']);

alert(pastResult['F_sName']);

alert(pastResult['F_sAddress']);
