提问by Peter
i hope somebody can help me, the array value is empty in the post.
我希望有人可以帮助我，帖子中的数组值为空。
$(function start() {
c_all = new Array('#div { font-color:#ff0000; border:1px solid #00ff00; }', '#div_2 { font-color:#ff0000; }', '.line2 { font-color:#00ffff; }');
css(c_all);
});
function css(x) {
values = new Array();
for (i = 0; i < x.length; i++) {
c0_selector = '' + x[i].match(/^.*{/) + '';
c0_selector = c0_selector.replace(/\s*/g, '');
c0_selector = c0_selector.replace(/{/, '');
x[i] = x[i].replace(/^.*{/, '');
x[i] = x[i].replace(/}/, '');
c0_arr = x[i].split(';');
values['' + c0_selector + ''] = new Array();
$('#log').append(''+c0_selector+'<br />');
for (i2 = 0; i2 < c0_arr.length; i2++)
{
values[''+c0_selector+''][i2] = c0_arr[i2].split(':');
$('#log').append(''+c0_arr[i2]+'<br />');
}
}
$.ajax({
type: 'post',
data: JSON.stringify(values),
contentType: 'application/json',
dataType: 'json'
});
}

Try making valuesan Object, (like it should be in javascript for named keys).
尝试创建values一个对象，（就像它应该在 javascript 中用于命名键）。
var values = {};
Also, it is a reallygood idea to declare your variables with the varkeyword, so you're not creating global variables.
此外，使用关键字声明变量是一个非常好的主意var，这样您就不会创建全局变量。
Also, no need for '' + c0_selector + ''since you already have a String. Just do c0_selector.
此外，不需要，'' + c0_selector + ''因为您已经有一个字符串。就做c0_selector。
Finished product logs the populated Object. http://www.jsfiddle.net/V9Euk/450/

This is straight from the ECMAScript spec.
这直接来自 ECMAScript 规范。
The abstract operation JA(value) serializes an array. It has access to the stack, indent, gap, and space of the invocation of the stringify method. The representation of arrays includes only the elements between zero and array.length – 1 inclusive. Named properties are excluded from the stringification. An array is stringified as an open left bracket, elements separated by comma, and a closing right bracket.
抽象操作 JA(value) 序列化一个数组。它可以访问调用 stringify 方法的堆栈、缩进、间隙和空间。数组的表示仅包括介于 0 和 array.length – 1 之间的元素。命名属性从字符串化中排除。数组被字符串化为左左括号、逗号分隔的元素和右括号。
Basically any named properties are excluded from the result.
基本上所有命名属性都从结果中排除。
