• 原生js实现拖拽弹框的效果

    研究了一上午，模仿了拖拽弹框的效果，小有成就

    <script type="text/javascript">
    function getByClass(classname,parent){
    var par=parent||document,
    eles=par.getElementsByTagName("*"),
    needArr=[];
    for(var i=0;i<eles.length;i++){
    if(eles[i].className==classname){
    needArr.push(eles[i]);
    }
    }
    return needArr;
    }
    var oDom=document.getElementById("dialogin_html");
    var oTarget=getByClass("dialog-tit",oDom)[0];
    window.onload=drag;
    function drag(){
    oTarget.onmousedown=fnDown;
    }
    function fnDown(event){
    var e=event||window.event,
    difX=e.clientX-oDom.offsetLeft,
    difY=e.clientY-oDom.offsetTop;

    document.onmousemove=function(e){
    var e=e||window.event,
    x=e.clientX-difX,
    y=e.clientY-difY,
    docuW=document.body.clientWidth||document.documentElement.clientWidth,
    docuH=document.body.clientHeight||document.documentElement.clientHeight;
    if(x<0){
    x=0;
    }
    if(y<0){
    y=0;
    }
    if(x>docuW-oDom.offsetWidth){
    x=docuW-oDom.offsetWidth;
    }
    if(y>docuH-oDom.offsetHeight){
    y=docuH-oDom.offsetHeight;
    }
    oDom.style.left=x+"px";
    oDom.style.top=y+"px";
    document.title=e.clientX-difX+":"+(e.clientY-difY);
    }
    document.onmouseup=function(){
    document.onmousemove=null;
    document.onmouoseup=null;
    }

    }
    </script>

    以上是大致的js代码，具体代码如下：
