如何在Javascript
中的对象中插入项目?
var colorData = new Object();
var stateData = {
states:
[
{ 'state' : 'CA', 'color' : '#61c419', 'amaguide' : '5'},
{ 'state' : 'AZ', 'color' : '#61c419', 'amaguide' : '5'}
]
}
for (var i = 0; i < stateData.length; i++) {
colorData.push(stateData[i].state + ':' + stateData[i].color);
}
-------------------编辑--------------------
我想要以下格式的新
colorData
:-{'CA': '#61c419', 'AZ':'#61c419'}
谢谢
最佳答案
Array.prototype.map()是您的朋友:
var stateData = {
states:
[
{ 'state' : 'CA', 'color' : '#61c419', 'amaguide' : '5'},
{ 'state' : 'AZ', 'color' : '#61c419', 'amaguide' : '5'}
]
};
var colorData = stateData.states.map(function(ele) {
return ele.state + ':' + ele.color;
});
如果希望结果为
{CA: '#61c419', AZ: '#61c419'}
,则:var colorData = stateData.states.reduce(function(v, w) {
v[w.state] = w.color;
return v;
}, {});
