I have a function which returns an object of form: [{"key":"name","value":"ali","key":"age","value":"56"}] when called as given below. How can I have it return same kind of object but without the square brackets?
我有一个函数返回一个形式的对象：[{“key”：“name”，“value”：“ali”，“key”：“age”，“value”：“56”}]当被调用时下面。我怎么能让它返回相同类型的对象但没有方括号？
setProperties('{"name":"ali","age":"56"}');
function setProperties(str) {
var properties = [];
var json = jQuery.parseJSON(str);
for (property in json) {
properties.push({
key: property,
value: json[property]});
}
return properties;
}

return properties[0]; // returns the first element of the list instead of the whole list

The square brackets indicate an Array literal, so if you just select the first element of the Array: [{"name":"ali","age":"56","height":"xyz"}][0] it returns the Object you want.
方括号表示一个数组文字，所以如果你只选择数组的第一个元素：[{“name”：“ali”，“age”：“56”，“height”：“xyz”}] [0]它返回你想要的对象。
