The stris already an object.
该str已经是一个对象。
You could use jQuery.mapmethod.
您可以使用jQuery.map方法。
var str = {"12:30 PM":"1:00 PM","11:30 AM":"12:00 PM"};
var result = $.map(str, function(value, key) {
return [[key, value]];
});

Try this mapexample
试试这个map例子
var str = {"12:30 PM":"1:00 PM","11:30 AM":"12:00 PM"};
var convert = Object.keys(str).map(function(k) {
return [k, str[k]];
});
If you need support for IE <= 8, see Object.keys pollyfilland Array.prototype.map pollyfill
如果您需要支持 IE <= 8，请参阅Object.keys pollyfill和Array.prototype.map pollyfill

var str = '{"12:30 PM":"1:00 PM","11:30 AM":"12:00 PM"}';
object = JSON.parse(str);
var my_array = new Array();
for(var key in object ){
my_array[key] = object[key];
}

Can you try this.
你可以试试这个。
var p = {"12:30 PM":"1:00 PM","11:30 AM":"12:00 PM"}
var o = [];
for (k in p) {
if (p.hasOwnProperty(k)) {
o.push([k, p[k]]);
}
}

Assuming you're talking about actual stringthat you're getting from the server, you can do a plain string replacement:
假设您正在谈论从服务器获取的实际字符串，您可以进行简单的字符串替换：
var str = '{"12:30 PM":"1:00 PM","11:30 AM":"12:00 PM"}';
str = str
.replace('{"','[["')
.replace('"}','"]]')
.replace('","','"],["')
.replace(/":"/g,'","')
This will make strinto stringrepresenting an array. To make a real array out of it you can do something like this:
这将str变成表示数组的字符串。要从中制作一个真正的数组，您可以执行以下操作：
var arr;
eval('arr = ' + str);
This is the only legitimate use of evalI can advocate.
这是eval我可以提倡的唯一合法使用。
