Javascript哈希替换错误

问题描述

这有什么问题？

散列是：＃/ search = hello / somethingelse /

 >  hash.replace（）实际上并没有改变哈希，只返回一个值因为它是一个字符串函数）。尝试分配该结果，使用： 
 
 
  window.location.hash = window.location.hash.replace（/ search =（[ ^ \ /] *）/ gi，search =+ value）; 
  
另一方面， window.location.replace（） 实际上是一个改变URL的函数，但这不能直接与正则表达式一起工作。
 
What's the problem with this?
the hash is : #/search=hello/somethingelse/
window.location.hash.replace(/search=([^\/]*)/gi, "search=" + value);
EDIT:
I want to change just a specific part of the hash not the whole hash.
 解决方案 
hash.replace() does not actually change the hash, only return a value (as it is a String function). Try assigning that result, using:
window.location.hash = window.location.hash.replace(/search=([^\/]*)/gi, "search=" + value);
On the other hand, window.location.replace() is actually a function that changes the URL, but that does not work directly with regexes.
