JQUERY：如何将函数作为参数传递给$（）？

Question

How do you pass a function as a parameter to $()? For example

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 $() 

Answer 1

Reference: http://api.jquery.com/jQuery/

$() takes in different types of parameters in different situations.

So the point should be what your autoplace() function is returning . Then what returns gets passed into $()

Example:

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')
