如图,需要正则匹配14117.56这个数据
即在字符串(以下都为字符串)
var gridJSON = ‘[{"value":["10440312"],"key":1},{"value":["13278875"],"key":2},{"value":["78.62"],"key":3},{"value":["16249"],"key":4},{"value":["0.16"],"key":5},
{"value":["1.35"],"key":6},{"value":["0.87"],"key":7},{"value":["14117.56"],"key":8},{"value":["10440312"],"key":12}]‘;
中匹配14117.56这个字符串
正则的时候这么写
var priceRegex = new Regex("0.87\"],\"key\":7},{\"value\":[\"(.*)\"],\"key\":8}");
找不到匹配项,要将正则表达式改为
var priceRegex = new Regex("0.87\"],\"key\":7},{\"value\":\\[\"(.*)\"],\"key\":8}");
才可以匹配到
表达正括号 [ 应该写作 \\[
