arrayToJson将数组转化为json格式的js代码_javascript技巧

函数代码:

复制代码 代码如下:

function arrayToJson(o) {
var r = [];
if (typeof o == "string") return "\"" + o.replace(/([\'\"\\])/g, "\\$1").replace(/(\n)/g, "\\n").replace(/(\r)/g, "\\r").replace(/(\t)/g, "\\t") + "\"";
if (typeof o == "object") {
if (!o.sort) {
for (var i in o)
r.push(i + ":" + arrayToJson(o[i]));
if (!!document.all && !/^\n?function\s*toString\(\)\s*\{\n?\s*\[native code\]\n?\s*\}\n?\s*$/.test(o.toString)) {
r.push("toString:" + o.toString.toString());
}
r = "{" + r.join() + "}";
} else {
for (var i = 0; i r.push(arrayToJson(o[i]));
}
r = "[" + r.join() + "]";
}
return r;
}
return o.toString();
}

演示代码:

<script> function arrayToJson(o) { var r = []; if (typeof o == "string") return "\"" + o.replace(/([\'\"\\])/g, "\\$1").replace(/(\n)/g, "\\n").replace(/(\r)/g, "\\r").replace(/(\t)/g, "\\t") + "\""; if (typeof o == "object") { if (!o.sort) { for (var i in o) r.push(i + ":" + arrayToJson(o[i])); if (!!document.all && !/^\n?function\s*toString\(\)\s*\{\n?\s*\[native code\]\n?\s*\}\n?\s*$/.test(o.toString)) { r.push("toString:" + o.toString.toString()); } r = "{" + r.join() + "}"; } else { for (var i = 0; i < o.length; i++) { r.push(arrayToJson(o[i])); } r = "[" + r.join() + "]"; } return r; } return o.toString(); } var str2="脚本之家,sc.jb51.net,素材下载,百度,456,456,456"; var arr1=str2.split(","); alert(arrayToJson(arr1)); </script>
