String url of json object

Question

I tried to make a JSON object from a string url without success

I have it:

var URL = "http://localhost/index.php?module=search&param1=4"; 

I need this:

 var dir = index.php; var result = { module:'search', param1:4 }; 

Can someone help me with the code?

Answer 1

It’s not entirely correct to post the link here, but in this case, what the OP requires is just a library for parsing URLs.

And here it is: http://james.padolsey.com/javascript/parsing-urls-with-the-dom/

Answer 2

This function can parse AND variables from a string URL:

 function url2json(url) { var obj={}; function arr_vals(arr){ if (arr.indexOf(',') > 1){ var vals = arr.slice(1, -1).split(','); var arr = []; for (var i = 0; i < vals.length; i++) arr[i]=vals[i]; return arr; } else return arr.slice(1, -1); } function eval_var(avar){ if (avar[1].indexOf('[') == 0) obj[avar[0]] = arr_vals(avar[1]); else obj[avar[0]] = avar[1]; } if (url.indexOf('?') > -1){ var params = url.split('?')[1]; if(params.indexOf('&') > 2){ var vars = params.split('&'); for (var i in vars) eval_var(vars[i].split('=')); } else eval_var(params.split('=')); } return obj; } 

In your case:

 obj = url2json("http://localhost/index.php?module=search&param1=4"); console.log(obj.module); console.log(obj.param1); 

gives:

 "search" "4" 

If you want to convert "4" to an integer, you need to do this manually.

This simple javascript does it.

 url = "http://localhost/index.php?module=search&param1=4"; var parameters = url.split("?"); var string_to_be_parsed = parameters[1]; var param_pair_string = string_to_be_parsed.split("&"); alert(param_pair_string.length); var i = 0; var json_string = "{" for(;i<param_pair_string.length;i++){ var pair = param_pair_string[i].split("="); if(i < param_pair_string.length - 1 ) json_string += pair[0] + ":'" + pair[1] + "',"; else json_string += pair[0] + ":'" + pair[1] + "'"; } json_string += "}"; alert(json_string);
