jQuery.grep（）匹配www和非www，http / https的URL

Question

I am using jquery to search a json string for the matched url and then fetch all the data inside that object.

I fetch the url with

var url = window.location.href;

However this returns

http://somesite.com/

inside the json string could be any of the following

• http://somesite.com/
• http://somesite.com
• http://www.somesite.com/
• http://www.somesite.com https://somesite.com/

etc etc.

My code is to match the url and then do something. How would I go about using jQuery.grep() to take the different style urls in the query? Below is my code so far.

var url = window.location.href;
var json = exampleJsonString;
var js = JSON.parse(json);
var result = $.grep(js, function(e){ return e.url == url; });

if (result.length == 0) {
  // not found :(
  console.log('Not found');
} else if (result.length == 1) {
  // Result matched
  console.log(result);

} 

else {
  // multiple items found
  console.log('multiple items found');
  console.log(result); 
}

What I want to do is check for somesite.com using jquery grep. As in this line it checks if the string is equal.

var result = $.grep(js, function(e){ return e.url == url; });

You can use grep function to filter the records. Here in your case want to check different URL's in the object like ' http://somesite.com/ ',' http://somesite.com ' etc, mention all the URL's that you want to consider in grep function. Here is the sample code.

   var varObj = jQuery.grep(dataobject, function (a) {
            if (a.url == "http://somesite.com/" || a.url == "http://somesite.com" || a.url == "http://www.somesite.com/")
                return true;
        });
