js字符串替换问题

Question

想做一个点击跳转url的js方法。

点击提交，取这两个input的值，
把var str="http://www.baidu.com/loupan_0_0_0_0_0_0_0_0_0_0.html"
这个字符串分别替换最后俩0，就是拼接成
"http://www.baidu.com/loupan_0_0_0_0_0_0_0_0_1000_20000.html"

Answer 1

function replace(str, minPrice, maxPrice){
    return str.replace(/^http:\/\/www.baidu.com\/loupan((_[0-9]+){8})_([0-9]+)_([0-9]+).html$/, `http://www.baidu.com/loupan$1_${minPrice || 0}_${maxPrice || 0}.html`)
}

Answer 2

var str="http://www.baidu.com/loupan_0_0_0_0_0_0_0_0_0_0.html";
