regex - Why is this simple javascript not working? -

-

new js here. trying detect existence of string in present page's url this:

var url = window.location; var param = /\?provider=/i; if (url.search(param) != -1) {     alert('it exist'); } else     alert('it not exist');

it works when manually define url variable so

var url = 'http://google.com?provider='

but when try grab dynamically in above script doesn't work, there way make work?

you want href property on location object, this:

var url = window.location.href; var param = /\?provider=/i; if (url.search(param) != -1) {     alert('it exist'); } else     alert('it not exist');

location isn't string, it's object, , doesn't have .search() method, .href string does.

php - PHPDoc: @return void necessary? -

is necessary this: /** * ... * * @return void */ i have quite few methods don't have return value, , seems redundant put in comment. considered bad form leave out? if makes clear documentation, leave in, isn't strictly necessary. it's entirely subjective decision. personally, leave out. edit stand corrected. after little googling, wikipedia page says: @return [type description] tag should not used constructors or methods defined void return type. the phpdoc.org website says: @return datatype description @return datatype1|datatype2 description the @return tag used document return value of functions or methods. @returns alias @return support tag formats of other automatic documentors the datatype should valid php type (int, string, bool, etc), class name type of object returned, or "mixed". if want explicitly show multiple possible return types, list them pipe-delimited without spaces (e.g. "@retur...
