First, the regular expression, directly find the value of the right side of the parameter equals. However, it is not feasible to have & after this parameter.
< SCRIPT language = "JavaScript" >
var str = window.location.href;
var es =/clid =/;
Es.exec (str);
var right = Regexp.rightcontext;
if (right = = "1")
{
Sub_nav_4.style.display = "block";
Li4.style.background = "#a1ca00";
}
</script > Second, the parameters can be found are paid to Argsarr array, in the future can be used Argsarr[i] for corresponding access, the method is good, too long, parameters are not easy to remember. /**
* Extract the parameters from the URL
*/
function Getargs ()
{
Plus the meaning of substring is to get rid of the query string. Resolution
var query = window.location.search.substring (1);
Defines an array that holds the string arguments that are taken out.
var Argsarr = new Object ();
Gets the query string parameter in the URL
var query = Window.location.search;
query = query.substring (1);
The pairs here is an array of strings
var pairs = Query.split ("&");//name=myname&password=1234&sex=male&address=nanjing
for (Var i=0;i<pairs.length;i++)
{
var sign = pairs[i].indexof ("=");
If no = number is found, skip and skip to the next string (Next loop).
if (sign = = 1)
{
Continue
}
var Akey = pairs[i].substring (0,sign);
var avalue = pairs[i].substring (sign+1);
Argsarr[akey] = Avalue;
}
return Argsarr;
}
Third, the simplest method, similar to the second, but did not create an array of stored parameters, you can directly access the name of the parameter, easy to read. < SCRIPT language = "JavaScript" >
function Getarg ()
