jQuery，如何获取JavaScript中的URL GET变量？

Question

i have a link:

<a href="?
processor=<?php echo $value['processor']; ?>&
auth_code=<?php echo $value['auth_code']; ?>
" id="buttonDetails">View Detail</a>

and a function:

function getUrlVars(parsedUrl) {
var vars = {};
parsedUrl.replace(/[?&]+([^=&]+)=([^&]*)/gi,
        function(m, key, value) {
            vars[key] = value;
        });
return vars;
}

what i am doing is passing the link to this function;

var url = $('#buttonDetails').attr('href'); // "?processor=25&auth_code=12"
var first = getUrlVars(url);
alert (first );

this alert will give me [object Object]

any ideas what i am doing wrong?

edit: another way would be to:

var first = getUrlVars()["processor"];
alert(processor);

but this doesn't work as well

edit:

the links are created in a php loop:

foreach($test as Value){
 // here is the link being created and the result is more links.
}

also i changed the id to class for the link.

and i'm doing:

$('.buttonDetails').each(function(){
var parsed = getUrlVars($(this).attr('href'));
console.log(parsed['processor']);

});

this will give me undefined

this console.log(parsed); will give me multiple objects with the data inside them. but when i try to get some specifics from inside the object i get undefined

why would this not work?

thanks again

Answer 1

In this example:

var url = $('#buttonDetails').attr('href'); // "?processor=25&auth_code=12"
var first = getUrlVars(url);
alert (first );

The reason the alert gives you [object Object] is because that's what first is:

Object
    auth_code: "12"
    processor: "25"

Your second example doesn't work because you are not passing a value to the getUrlVars function. Try this:

var url = $('#buttonDetails').attr('href'), // "?processor=25&auth_code=12"
    parsed = getUrlVars(url);

alert(parsed['processor']);

jQuery doesn't have a built in function. I use this: http://www.netlobo.com/url_query_string_javascript.html

Possible solutions:

var first = getUrlVars(url)["processor"];
alert(first); // not alert(processor)

or

var first = getUrlVars(url);
alert (first.processor); // or alert(first["processor"]
