i have to find all href attribute in which "table" string should be present eg:href="#table1(t1)" and then i have to replace it with the string present in braces eg:href="t1"
推荐答案
如果我理解正确，你需要这个：
If i understand you correctly, you need this:
var re = /(#table\d+)|\((\w{1,2})(\))/g;
var str = '<p id="para"> demo test demo test demo test demo test demo test demo test demo test demo test demo test demo test demo test demo test demo test demo test demo test demo test demo test demo test demo test demo test demo test demo test demo test demo test demo<a href="#table1(t1)" id="ytD2F">table1</a> test demo test demo test demo test demo test demo <a href="#table2(t2)" id="ytD2F">table2</a> demo test demo test demo test demo test demo test demo test demo test demo test demo test demo test </p>';
var subst = '$2';
var result = str.replace(re, subst);
console.log(result);
