js changes the address bar URL parameters to solve the url parameter problem_Basic knowledge

Nowadays, when making web pages, we often encounter the problem of dealing with address bar parameters, but I always do it based on feeling. Later, there are many loopholes and I don’t know where to start. Therefore, I made a special method to modify the address bar parameters. This time, You don’t have to worry anymore, haha!

The following is the method I compiled, it is very simple to use:

Copy code The 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, such as http://www.huistd.com/?id=3&ttt=3
par is the parameter name, par_value is the value of the parameter to be changed. The calling result is as follows:
changeURLPar(test, 'id', 99); // http://www.huistd.com/?id=99&ttt=3
changeURLPar(test, 'haha', 33); // http://www.huistd.com/?id=99&ttt=3&haha=33
How about it, it’s very useful! Ha ha
