含羞默默一张一合效果-含羞默默怎么解释

含羞默默一张一合效果---田

首先展示“田”字效果

实现思想主要分为几部分

随机生成颜色值

var getRandomColor = function(){  
    return  '#' +  
        (function(color){  
        return (color +=  '0123456789abcdef'[Math.floor(Math.random()*16)])  
            && (color.length == 6) ?  color : arguments.callee(color);  
    })('');  
}

创建span标签，插入div中。

creSpan函数，n指当前个数，mpid指父容器div，mleft指当前span的left的值，mtop指当前span的top值

function creSpan(n,mpId,mleft,mtop){  
    var mSpan = document.createElement("span");    
    var pId = mpId[0];  
    pId.appendChild(mSpan);  
    with(mSpan.style){  
        left = mleft+"px";  
        top = mtop+"px";  
        background = getRandomColor();  
    }  
}

生成“田”字

创建一个二维数组保存每个creSpan的对象。myleft=100，mtop=50 默认初始值距左距顶的距离。

画“田”字，使用双重循环生成。

var myleft = 100;  
var mytop = 50;  
var arr = new Array();  
var test =  $("#test");  
for(var j=0;j<23;j++){  
    arr[j] = new Array();  
    if(j<3){  
        for(var i=0;i<19;i++){  
            myleft+=32;  
            arr[j][i] = new creSpan((j+1)*(i+1),test,myleft,mytop);  
        }  
    }  
    else if(j>2&&j<10){  
        for(var i=0;i<19;i++){  
            myleft+=32;  
            if(i<3){  
                arr[j][i] = new creSpan((j+1)*(i+1),test,myleft,mytop);  
            }  
            else if(i>7&&i<11){  
                arr[j][i] = new creSpan((j+1)*(i+1),test,myleft,mytop);  
            }  
            else if(i>15){  
                arr[j][i] = new creSpan((j+1)*(i+1),test,myleft,mytop);  
            }  
        }  
    }  
    else if(j>9&&j<13){  
        for(var i=0;i<19;i++){  
            myleft+=32;  
            arr[j][i] = new creSpan((j+1)*(i+1),test,myleft,mytop);  
        }  
    }  
    else if(j>12&&j<20){  
        for(var i=0;i<19;i++){  
            myleft+=32;  
            if(i<3){  
                arr[j][i] = new creSpan((j+1)*(i+1),test,myleft,mytop);  
            }  
            else if(i>7&&i<11){  
                arr[j][i] = new creSpan((j+1)*(i+1),test,myleft,mytop);  
            }  
            else if(i>15){  
                arr[j][i] = new creSpan((j+1)*(i+1),test,myleft,mytop);  
            }  
        }  
    }  
    else{  
        for(var i=0;i<19;i++){  
            myleft+=32;  
            arr[j][i] = new creSpan((j+1)*(i+1),test,myleft,mytop);  
        }  
    }  
    mytop+=32;  
    myleft=100;  
}

当鼠标移动到每个span上时尖尖缩小，然后慢慢张开。

主要采用jquery中的animate函数。控制width，height，left，top的值。

$.each($("#test span"),function(k,v){  
    $(this).mouseover(function(){  
        $(this).animate({  
            width:"10px",  
            height:"10px",  
            left:"+="+parseInt(30-20)/2+"px",  
            top:"+="+parseInt(30-20)/2+"px" 
        },3000,function(){  
            $(this).animate({  
                width:"30px",  
                height:"30px",  
                left:"-="+parseInt(30-20)/2+"px",  
                top:"-="+parseInt(30-20)/2+"px" 
            },1000);  
        });  
    });  
});
