JS获取参数

    <script>

function getArgs( ) {

    var args = new Object( );

    var query = location.search.substring(1);     // Get query string

    var pairs = query.split("&");                 // Break at ampersand

    for(var i = 0; i < pairs.length; i++) {

        var pos = pairs[i].indexOf('=');          // Look for "name=value"

        if (pos == -1) continue;                  // If not found, skip

        var argname = pairs[i].substring(0,pos);  // Extract the name

        var value = pairs[i].substring(pos+1);    // Extract the value

        value = decodeURIComponent(value);        // Decode it, if needed

        args[argname] = value;                    // Store as a property

    }

    return args;                                  // Return the object

}

</script>

 

用法

var a= getArgs();

a["link"]
