最近在做九宫格的抽奖,在看别人写的代码时看到这样的代码
var lottery=
{
index:-1
,
count:0
,
.........
init:function(id){
},
roll:function(){
}
};
简单,就是对整个页面的初始化。再详细一点说,就是这样的写法是最近几年开始流行的json写法,把所有的function,所有的变量等,都用
var o =
{
x: func,
y: ""
,
z: obj
}
这样的写法来写。而调用直接用o.x ;o.z()即可如
<script type="text/javascript">
var obj=
{
count:0
,
timer:0
,
init:function(str){
alert("init调用:"+
str);
},
exit:function(str){
alert("exit调用:"+
str);
}
};
function someThing(){
obj.timer += 1
;
obj.init('init'
);
obj.exit('exit'
);
alert(obj.timer)
}
window.onload=
function(){
someThing();
}
</script>
