Try:
尝试：
var initialString = "'California',51.2154,-95.2135464,'data'";
var dataArray = initialString .split(",");

Use the split function which is available for strings.
使用可用于字符串的 split 函数。
var ar = "'California',51.2154,-95.2135464,'data'".split(",");
and convert the numbers to actual numbers, not strings.
并将数字转换为实际数字，而不是字符串。
for (var i = ar.length;i--; ) {
var tmp = parseFloat(ar[i]);
ar[i] = (!isNaN(tmp)) ? tmp: ar[i].replace(/['"]/g,"");
}
Beware, this will fail if your string contains arrays/objects.
请注意，如果您的字符串包含数组/对象，这将失败。

Since you format almost conforms to JSON syntax you could do the following :
由于您的格式几乎符合 JSON 语法，您可以执行以下操作：
var dataArray = JSON.parse ('[' + initialString.replace (/'/g, '"') + ']');
That is add '[' and ']' characters to be beginning and end and replace all "'' characters with '"'. than perform a JSON parse.
即添加 '[' 和 ']' 字符作为开头和结尾，并用 '"' 替换所有 "'' 字符。而不是执行 JSON 解析。
