我需要转换这个 json 对象：
"forms":
{
"Circle":
{
"color" : "red",
"size" : "1"
},
"Square":
{
"color" : "blue",

"triangle":

"color" : "black",
"size" : "4"

Into an javascriptArray. The array should contain formType, color and size. I have created the following script
进入一个 javascriptArray。该数组应包含 formType、颜色和大小。我创建了以下脚本
var formsArr=[];
$.each(forms, function(i, obj){ var form={color: obj.color, size: obj.size};
formsArr.push(form);
The array only contains color and size. I want it to also containt formType ie. Circle, how can I get the key?

Here's a way to do it:
这是一种方法：
var forms = {
"Circle": {
"color" : "red",
"size" : "1"
},
"Square": {
"color" : "blue",
"size" : "3"
},
"triangle": {
"color" : "black",
"size" : "4"
}
};
var result = Object.keys(forms).map(function(key) {
return { type: key, color: this[key].color, size: this[key].size };
}, forms);
With jQuery:
使用 jQuery：
var result = $.map(forms, function(val, key) {
return { type: key, color: val.color, size: val.size };
});
