如何从jquery / javascript计算数组的键名？

Question

伙计们，我有一个以json格式encoded的数组。它看起来如下：-

{"result":[{"pid":"24","uf":"hancy061","ot":"sanjit061","dn":"November 6,2015 at 02:18pm","view":"0","nu":"hancy061"},{"pid":"23","uf":"hari061","ot":"sanjit061","dn":"November 6,2015 at 01:09pm","view":"0","nu":"hari061"}]}

现在简而言之，我的问题是我可以计算来自jquery / javascript的view总数吗？我想计算view并将该数字存储在var 。请仅对这种东西计数可能没什么大不了的。从jquery / javascript计算该view方法？帮助需要的人。

您可以使用RegExp和.match

 var data = JSON.stringify({ "result": [{ "pid": "24", "uf": "hancy061", "ot": "sanjit061", "dn": "November 6,2015 at 02:18pm", "view": "0", "nu": "hancy061" }, { "pid": "23", "uf": "hari061", "ot": "sanjit061", "dn": "November 6,2015 at 01:09pm", "view": "0", "nu": "hari061" }] }); var count = (data.match(/view/g) || []).length; console.log(count);
