Some thoughts:(一些想法：)

• jQuery is a JavaScript library, not a language.(jQuery是一个JavaScript库，而不是一种语言。)

  So, JavaScript arrays look something like this:(所以，JavaScript数组看起来像这样：)

   var someNumbers = [1, 2, 3, 4, 5]; 

• { pageNo: $(this).text(), sortBy: $("#sortBy").val()} is a map of key to value.({ pageNo: $(this).text(), sortBy: $("#sortBy").val()}是键值的映射。)

  If you want an array of the keys or values, you can do something like this:(如果你想要一个键或值的数组，你可以这样做：)

   var keys = []; var values = []; var object = { pageNo: $(this).text(), sortBy: $("#sortBy").val()}; $.each(object, function(key, value) { keys.push(key); values.push(value); }); 

• objects in JavaScript are incredibly flexible.(JavaScript中的对象非常灵活。)

  If you want to create an object {foo: 1} , all of the following work:(如果要创建对象{foo: 1} ，则以下所有工作：)

   var obj = {foo: 1}; var obj = {}; obj['foo'] = 1; var obj = {}; obj.foo = 1; 

To wrap up, do you want this?(总结一下，你想要这个吗？)

var data = {};
// either way of changing data will work:
data.pageNo = $(this).text();
data['sortBy'] = $("#sortBy").val();

$("#results").load("jquery-routing.php", data);
