【问题描述】：
我从 javascript 中的 ajax 调用中获取数据：
$.ajax({
type: "GET",
url:URL,
headers: {
'Access-Control-Allow-Origin': '*'
},
async: false,
dataType: "text",
success: function (data) {
result=data;
}
我们以这种方式得到响应：

所以这里我的要求是从数据中提取“类型”值。
"type":"https://xxxxxx/cl/SiteType/perimeterZone"
"type":"https://xxxxxx/cl/xxxxx/constructionZone"
我们可以不使用正则表达式吗？
仅供参考：我们正在使用 OpenLayers3。
【问题讨论】：
-
你尝试了什么？我认为你不应该用正则表达式来做。
-
不使用正则表达式可以吗？是的，你可以。
-
在寻求帮助之前，您至少应该尝试自己解决问题。
-
@SubhranilSengupta 基本上是 vlaz 所说的。当您在堆栈溢出上发帖时，您应该说出您尝试过的内容，而您的问题不会涉及您尝试过的任何内容。查看您尝试过的方法并了解它为什么不起作用有助于我们回答您的问题（所以我们不会告诉您去做您已经尝试过的事情，也不会帮助说明您要寻求什么样的解决方案） .

@RockySims 谢谢，我尝试了正则表达式和其他一些方法来获取值，但失败了。下次我会好好照顾的。
