Modify URL parameters in the address bar in js to solve the url parameter problem

Currently, webpage processing often involves processing address bar parameters, but it has always been done by feeling, and I don't know where to change it. Therefore, I made a special method to modify the parameters in the address bar, so I don't have to worry about it anymore. Haha!

The following is my compilation method, which is easy to use.:
Copy codeThe Code is as follows:
Function changeURLPar (destiny, par, par_value)
{
Var pattern = par + '= ([^ &] *)';
Var replaceText = par + '=' + par_value;
If (destiny. match (pattern ))
{
Var tmp = '/\' + par + '= [^ &] */';
Tmp = destiny. replace (eval (tmp), replaceText );
Return (tmp );
}
Else
{
If (destiny. match ('[\?] '))
{
Return destiny + '&' + replaceText;
}
Else
{
Return destiny + '? '+ ReplaceText;
}
}
Return destiny + '\ n' + par +' \ n' + par_value;
}

Destiny is the target string, for example, http://www.huistd.com /? Id = 3 & ttt = 3
Par is the parameter name and par_value is the value to be changed. The call result is as follows:
ChangeURLPar (test, 'id', 99); // http://www.huistd.com /? Id = 99 & ttt = 3
ChangeURLPar (test, 'hahaha', 33); // http://www.huistd.com /? Id = 99 & ttt = 3 & haha = 33
How are you doing? It's quite helpful! Haha
