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...展开

• 

pastResult是数组，所以只能用0，1，2

1 2 3 4 5 6 7 8 9

// 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']);
