[問題] JS物件Constructor的行為
小弟寫的這段JS code主要想把演算法用物件封裝起來，
然後在建構物件的時候產生對應的div(在$("con")這個div容器下)
再給每一個物件assign一個唯一的id去用來控制相對應的div.
var BOARD_W = 150, BOARD_H = 100, Z_idx = 1;
var gid = 0;
var board = function(x,y){
this.id = gid ++;
$("con").innerHTML += "<div id='b" + this.id + "'position: absolute; left: "
+ x + "px; top: " + y + "px; z-index: " + (Z_idx++) + "; width: " + BOARD_W +
"px; height: " + BOARD_H + "px;'></div>";
$("b" + this.id).onmousedown = function(event){
alert(this.id);
};
};
function Test(){
var a = new board(100, 100);
var b = new board(250, 250);
}
想請教一下為何在產生完a,b兩個物件後我用chrome去看#b1底下有onmousedown的event，
但#b0底下沒有?
只產生a物件的話#b0又有出現onmousedown的event?
