How to get the hashtag value and ampersand value o

问题:

I have a url like http://www.example.com/folder/file.html#val=90&type="test"&set="none"&value="reset?setvalue=1&setvalue=45"

Now I need to get the portion of url from starting from #, How do I get that, I tried using window.location.search.substr(); but looks like that searches for ? in a url. is there a method to get the value of url after #

How do I also get a portion of url from ampersand &

Thanks, Michael

回答1:

var hash = window.location.hash;

More info here: https://developer.mozilla.org/en/DOM/window.location

Update: This will grab all characters after the hashtag, including any query strings. From the MOZ manual:

window.location.hash === the part of the URL that follows the # symbol, including the # symbol.
You can listen for the hashchange event to get notified of changes to the hash in
supporting browsers.

Now, if you need to PARSE the query string, which I believe you do, check this out here: How can I get query string values in JavaScript?

To grab the hash:

location.hash.substr(1); //substr removes the leading #

To grab the query string

location.search.substr(1); //substr removes the leading ?

[EDIT - since you seem to have a sort query-string-esq string which is actually part of your hash, the following will retrieve and parse it into an object of name/value pairings.

var params_tmp = location.hash.substr(1).split('&'),
    params = {};
params_tmp.forEach(function(val) {
    var splitter = val.split('=');
    params[splitter[0]] = splitter[1];
});
console.log(params.set); //"none"

This will get the # and & values:

var page_url = window.location + "";       // Get window location and convert to string by adding ""
var hash_value = page_url.match("#(.*)");  // Regular expression to match anything in the URL that follows #
var amps;                                  // Create variable amps to hold ampersand array

if(hash_value)                             // Check whether the search succeeded in finding something after the #
{
    amps = (hash_value[1]).split("&");     // Split string into array using "&" as delimiter
    alert(amps);                           // Alert array which will contain value after # at index 0, and values after each & as subsequent indices
}
