When passing parameters on a js page, the parameter value contains special characters_javascript skills

A small problem encountered at work. In one page, window.showModel("comm/morelanguage.jsp?str=zh_CN:爱#;zh_TW:爱;en:love;",,,,); pops up another page and Pass the parameters to another page, and there will be a problem when the other page accepts the src parameter value. The value is wrong. I tested it because of the problem of # special characters. The method I adopted for these special characters is to pass

When parameters are used, str=escape('str=zh_CN:爱#;zh_TW:爱;en:love;') handles

When receiving parameters, after getting str, str=unescape(str);
