本文實例講述了jquery圖形密碼實現方法。分享給大家供大家參考。具體實現方法如下：
代碼如下:<script type="text/javascript" src="js/jquery.min.js"></script>
<script type="text/javascript">
$(document).ready(function() {
var n=0,y=['4','8','12','13','14','15','16'];
for(var i=1;i<=16;i++){
var Box='<span id="box_'+i+'" class="box" num="0"></span>';
$('#lower').append(Box);
if(i<=4){
$('#box_'+i+'').animate({left:100*i-100+"px"}, 0)
.show(0).delay(i*400-400).animate({width:"90px",height:"90px",top:"300px"}, 800).attr("num",i);
}else if(i<=8){
$('#box_'+i+'').animate({left:100*i-500+"px"}, 0)
.show(0).delay(i*400-400).animate({width:"90px",height:"90px",top:"200px"}, 800).attr("num",i);
}else if(i<=12){
$('#box_'+i+'').animate({left:100*i-900+"px"}, 0)
.show(0).delay(i*400-400).animate({width:"90px",height:"90px",top:"100px"}, 800).attr("num",i);
}else{
$('#box_'+i+'').animate({left:100*i-1300+"px"}, 0)
.show(0).delay(i*400-400).animate({width:"90px",height:"90px",top:"0px"}, 800).attr("num",i);
}
};
$('#lower span').bind("click",function(){
$(this).addClass("select");
var code=$(this).attr("num");
for (var j=0; j<y.length; j++){
if(code==y[j]){
y = jQuery.grep(y, function(n, i){
return (n != code);
});
n=n+1;
}else{
n=n+0;
}
};
if($('.select').length==7){
if(n==7){
$('#lower').empty().append('<a href="#"></a>');
$('#lower a').fadeIn(800);
}else{
$('#page').delay(1000).append('<div id="tips"><p>密碼錯了，重來吧！</p></div>');
$('#tips').slideDown(500).delay(2000).slideUp(500);
$('#lower span').removeClass("select");
n=0;
y=['4','8','12','13','14','15','16'];
}
}
});
});
</script>
希望本文所述對大家的jquery程序設計有所幫助。
