求一个js正则表达式

Question

检索一个json字符串;格式:varjson='[{"i":"t2","n":"xx","x":"12678","y":"10456","c":"","m":3},{"i":"t3","n":"xx","x":"13678","y":"11456","c":"","m":3},{"i":"t4","n":"xx","x":"18456","y":"13456","c":"","m":3}]';//条件11000

Answer 1

试试json.match(/\{[^{]+?\"x\":\"1[12][0-9]{3}\",\"y\":\"1[12][0-9]{3}\",[^}]+?\}/g)？看看我有没有写错
/\{[^{]+?//排除{，使用惰性匹配
\"x\":\"1[12][0-9]{3}\",//只匹配x从11000到12999的内容
\"y\":\"1[12][0-9]{3}\",[^}]+?\}/g//作用于全局
                            

Answer 2

没必要用正则啊。js处理json最合适不过了。
varjson='[{"i":"t2","n":"xx","x":"12678","y":"10456","c":"","m":3},{"i":"t3","n":"xx","x":"13678","y":"11456","c":"","m":3},{"i":"t4","n":"xx","x":"18456","y":"13456","c":"","m":3}]';
//条件11000
vardata=JSON.parse(json);
varresult=[];
data.forEach(function(item){
if(item.x>11000&&item.x<13000&&item.y>11000&&item.y<13000){
console.log(item);
result.push(item);
}
});
