Get current path

[html20009876]

This is my js function:

function navigate_Parameter(num)
{
	str = location.href+"?num="+num;
	location.href=str;
}

First time: http ://...../myfile.htm?num=1
Second time : http ://...../myfile.htm?num=1?num=2
so on...
Last time: http ://...../myfile.htm?num=1?num=2........?num=999

Is there a function to get sole http ://...../myfile.htm without parameters after the link?

BTW: I don't want to cut full URI to file path.

function navigate_Parameter(num)
{
        var placement = location.href.indexOf('?');
        var location_without_parameters = placement == -1 ? location.href : location.href.substr(0, placement);

	str = location_without_parameters+"?num="+num;
	location.href=str;
}

you are cutting

Try

str = "http://"+location.host+filePath+"?num="+num;
location.href=str;

I'd suggest:

function navigate_Parameter(num)
{
	str = location.href.split('?')[0] +"?num="+num;
	location.href=str;
}
