C # sogou map API application Summary (2 ),

Add the functional modules you want on the map

The Code is as follows:

1 var map; 2 window. onload = function () {3 var myOptions = {4 mapControl: false, // disable the default control 5 mapTypeId: sogou. maps. mapTypeId. ROADMAP 6} 7 map = new sogou. maps. map (document. getElementById ("map_canvas"), myOptions); // initialize map 8 9 10 var homeControlDiv = document. createElement ('div '); // create 11 homeControlDiv. style. position = "absolute"; 12 homeControlDiv. style. left = "20px"; 13 homeControlDiv. style. top = "5px"; 14 15 var homeControl = new HomeControl (homeControlDiv, map); // obtain control 16 map. getContainer (). appendChild (homeControlDiv); // Add the control to map 17 18 19} 20 function HomeControl (controlDiv, map) {21 22 controlDiv. style. padding = '5px '; 23 24 // ranging function 25 var goHomeText = document. createElement ('div '); 26 goHomeText. style. fontFamily = 'arial, sans-serif'; 27 goHomeText. style. backgroundColor = 'white'; 28 goHomeText. style. cursor = 'pointer '; 29 goHomeText. style. borderStyle = 'solid'; 30 goHomeText. style. borderWidth = '1px '; 31 goHomeText. style. borderColor = 'black'; 32 goHomeText. style. fontSize = '12px '; 33 goHomeText. style. textAlign = 'center'; 34 goHomeText. style. float = 'left'; 35 goHomeText. style. width = "60px"; 36 goHomeText. innerHTML = '<B> ranging </B>'; 37 controlDiv. appendChild (goHomeText); 38 39 // get coordinates 40 var SetZbText = document. createElement ('div '); 41 SetZbText. style. fontFamily = 'arial, sans-serif'; 42 SetZbText. style. backgroundColor = 'white'; 43 SetZbText. style. cursor = 'pointer '; 44 SetZbText. style. borderStyle = 'solid'; 45 SetZbText. style. borderWidth = '1px '; 46 SetZbText. style. borderColor = 'black'; 47 SetZbText. style. fontSize = '12px '; 48 SetZbText. style. textAlign = 'center'; 49 SetZbText. style. float = 'left'; 50 SetZbText. style. width = "60px"; 51 SetZbText. innerHTML = '<B> get coordinates </B>'; 52 controlDiv. appendChild (SetZbText); 53 54 // clear excess lookup 55 var setHomeText = document. createElement ('div '); 56 setHomeText. style. fontFamily = 'arial, sans-serif'; 57 setHomeText. style. backgroundColor = 'white'; 58 setHomeText. style. cursor = 'pointer '; 59 setHomeText. style. borderStyle = 'solid'; 60 setHomeText. style. borderWidth = '1px '; 61 setHomeText. style. borderColor = 'black'; 62 setHomeText. style. fontSize = '12px '; 63 setHomeText. style. textAlign = 'center'; 64 setHomeText. style. float = 'left'; 65 setHomeText. style. width = "60px"; 66 setHomeText. innerHTML = '<B> clear </B>'; 67 controlDiv. appendChild (setHomeText); 68 69}View Code

C language ^ how to use

A1 = 0x01; // 0000 0001
A2 = 0x00; // 0000 0000
A3 = 0x03; // 0000 0011
A4 = 0x02; // 0000 0010

B1 = a1 ^ a2; // 0000 0001
B2 = a1 ^ a3; // 0000 0010
B3 = a1 ^ a4; // 0000 0011

^ XOR operator. The bitwise value is 0 and the difference is 1. See the example above.

//
Examples of simple and practical problems:
====================================
======= A ======= B =========
There are two circuits on the top. The two switches are a and B respectively. The opening status is \ [1], and the closing status is/[0].
If both circuits are enabled or disabled.
If a turns on [1], B turns off [0], and circuit 1 Powers on
=====================
If a disables [0], B enables [1], and circuit 2 powers on.
====================================
In summary, the circuit fails in the and B states simultaneously [0]. When a and B are different, the power is charged [1].
