Jquery digital scroll switching plug-in implementation method

This time I will bring you the implementation method of the Jquery digital scrolling switching plug-in. What are the precautions for the implementation of the Jquery digital scrolling switching plug-in. The following is a practical case, let's take a look.

Let’s look at the example first:

CSS

.textC {
 position:absolute;
 width:500px;
 overflow:hidden;
 margin-top: 100px;
 line-height:30px;
 margin-left: 300px;
 height:30px;
}
.textC span {
 color: #13BEEC;
 font-size: 28px;
 font-weight: bold;
 font-family: Georgia, "Times New Roman", Times, serif;
 position: absolute;
}

HTML

<p class="textC"></p>
<p style="text-align:center;"><a style="float:left; margin-left:300px; margin-top:200px;" href="
javascript
:void(0);" onClick="NumbersAnimate.ChangeNumber(NumbersAnimate.RandomNum(10000000,19999999));">随机切换数字</a>
</p>

JS

<script src="http://libs.baidu.com/jquery/2.0.0/jquery.min.js"></script>
<script type="text/javascript">
$(function(){
 NumbersAnimate.Target=$(".textC");
 NumbersAnimate.Numbers=12389623;
 NumbersAnimate.Duration=1500;
 NumbersAnimate.Animate();
});
var NumbersAnimate={
 Target:null,
 Numbers:0,
 Duration:500,
 Animate:function(){
 var array=NumbersAnimate.Numbers.toString().split("");
 //遍历数组
 for(var i=0;i<array.length;i++){
  var currentN=array[i];
  //数字append进容器
  var t=$("<span></span>");
  $(t).append("<span class=\"childNumber\">"+array[i]+"</span>");
  $(t).css("margin-left",18*i+"px");
  $(NumbersAnimate.Target).append(t);
  //生成滚动数字,根据当前数字大小来定
  for(var j=0;j<=currentN;j++){
  var tt;
  if(j==currentN){
   tt=$("<span class=\"main\"><span>"+j+"</span></span>");
   }else{
   tt=$("<span class=\"childNumber\">"+j+"</span>");
  }
  $(t).append(tt);
  $(tt).css("margin-top",(j+1)*25+"px");
  }
  $(t).animate({marginTop:-((parseInt(currentN)+1)*25)+"px"},NumbersAnimate.Duration,function(){
  $(this).find(".childNumber").remove();
  });
 }
 },
 ChangeNumber:function(numbers){
 var oldArray=NumbersAnimate.Numbers.toString().split("");
 var newArray=numbers.toString().split("");
 for(var i=0;i<oldArray.length;i++){
  var o=oldArray[i];
  var n=newArray[i];
  if(o!=n){
   var c=$($(".main")[i]);
        var num=parseInt($(c).html());
   var top=parseInt($($(c).find("span")[0]).css("marginTop").replace(&#39;px&#39;, &#39;&#39;)); 
   
   for(var j=0;j<=n;j++){
    var nn=$("<span>"+j+"</span>");
    if(j==n){
    nn=$("<span>"+j+"</span>");
    }else{
    nn=$("<span class=\"yy\">"+j+"</span>");
    }
    $(c).append(nn);
    $(nn).css("margin-top",(j+1)*25+top+"px");
   }
   var margintop=parseInt($(c).css("marginTop").replace(&#39;px&#39;, &#39;&#39;)); 
   $(c).animate({marginTop:-((parseInt(n)+1)*25)+margintop+"px"},NumbersAnimate.Duration,function(){
    $($(this).find("span")[0]).remove();
    $(".yy").remove();
   });
  }
 }
 NumbersAnimate.Numbers=numbers;
 },
 
 RandomNum:function(m,a){
 var Range = a - m;  
    var Rand = Math.random();  
    return(m + Math.round(Rand * Range));  
 }
}
</script>

The plug-in is very simple to use
1 . When calling for the first time

NumbersAnimate.Target=$(".textC");
NumbersAnimate.Numbers=12389623;
NumbersAnimate.Duration=1500;
NumbersAnimate.Animate();

2. If the number changes, you only need to call the Change function when calling again

NumbersAnimate.ChangeNumber();

The plug-in has 3 parameters, which are:

Target: Parent container of numbers
Numbers: Displayed numbers
Duration: Scrolling speed, unit is milliseconds

Usage Note: Call Change when the number changes method, you need to ensure that the number of digits after the change is consistent with the previous number.

I believe you have mastered the method after reading the case in this article. For more exciting information, please pay attention to other related articles on the php Chinese website!
