Ways to get Address bar parameters using JavaScript _javascript tips

Copy Code code as follows:

/**
* Get Address bar parameters
*
* @example geturlstring (' id ')
*
* @desc call with the decision to ensure that the program is not wrong
* var myurl = geturlstring (' id ');
* IF (myurl!= null && myurl.tostring (). length > 1) {
* Alert (geturlstring ("id"));
*             }
*
* @param String param to get the name of the parameter in the address bar
* @return String Value
* @type String
*
* @name geturlstring ()
*
*/
function geturlstring (param) {
var svalue = Location.search.match (New RegExp ("[\?\&]" + M + "= ([^\&]*) (\&?)", "I"));
Return svalue? decodeURI (Svalue[1]): decodeURI (svalue);
}

Call the time unified to do such a judgment, to avoid you do not pass the parameters, such as your address is abc.html after no parameters, that forced output call results sometimes the error

Copy Code code as follows:

Window.onload = function () {
var myurl = getparm ("id");
if (Myurl!= null && myurl.tostring (). length > 1) {
Alert (Getparm ("id"));
}
}

So there won't be an error!

Note: ECMAScript v3 has removed the unescape () function from the standard and objected to its use, so it should be replaced with decodeURI () and decodeURIComponent ().
