如何将函数作为参数传递给$（）？例如

function autoplace(map){
  // do something with map
   };
var map = "Wassup";
$(autoplace(map));  // how to pass a function which takes a parameter, as a paramter to $()

参考：http://api.jquery.com/jQuery/

$()在不同情况下接受不同类型的参数。

所以重点应该是autoplace()函数返回。然后将返回的内容传递到$()

示例：

function autoplace(map) {

     var mapSelector = '#map_' + map,
         $map = $(mapSelector);

     // do something with map

     // return something that's suitable for $()
     // Just an example

     return mapSelector; // In this example, mapSelector ends up being '#map_Wassup'
}

var $myMap = $( autoplace('Wassup') );

// The result will be equivalent to $('#map_Wassup')
