篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了javascript popup提示相关的知识，希望对你有一定的参考价值。

程序如下，第一栏做了个数字限制，用Alert做的弹出窗口，现在想用POPUP做提示弹出窗口，并且该窗口可以用鼠标随意拖动并可以关闭。
能帮我解决的我送分呀！

一下是弹出div层特效代码
<script type="text/javascript">
var prox;
var proy;
var proxc;
var proyc;
var isIe=(document.all)?true:false;
function setSelectState(state)

var objl=document.getElementsByTagName('select');
for(var i=0;i<objl.length;i++)

objl[i].style.visibility=state;

function mousePosition(ev)

if(ev.pageX || ev.pageY)

return x:ev.pageX, y:ev.pageY;

return
x:ev.clientX + document.body.scrollLeft - document.body.clientLeft,y:ev.clientY + document.body.scrollTop - document.body.clientTop
;

//关闭
function closeWindow()

if(document.getElementById('back')!=null)

document.getElementById('back').parentNode.removeChild(document.getElementById('back'));

else

/*-------------------------鼠标拖动---------------------*/
var od = document.getElementById("fd");
var dx,dy,mx,my,mouseD;
var odrag;
var isIE = document.all ? true : false;
document.onmousedown = function(e)
var e = e ? e : event;
if(e.button == (document.all ? 1 : 0))

mouseD = true;

document.onmouseup = function()
mouseD = false;
odrag = "";
if(isIE)

od.releaseCapture();
od.filters.alpha.opacity = 100;

else

window.releaseEvents(od.MOUSEMOVE);
od.style.opacity = 1;

//function readyMove(e)
od.onmousedown = function(e)
odrag = this;
var e = e ? e : event;
if(e.button == (document.all ? 1 : 0))

mx = e.clientX;
my = e.clientY;
od.style.left = od.offsetLeft + "px";
od.style.top = od.offsetTop + "px";
if(isIE)

od.setCapture();
od.filters.alpha.opacity = 50;

else

window.captureEvents(Event.MOUSEMOVE);
od.style.opacity = 0.5;

//alert(mx);
//alert(my);

document.onmousemove = function(e)
var e = e ? e : event;

//alert(mrx);
//alert(e.button);
if(mouseD==true && odrag)

var mrx = e.clientX - mx;
var mry = e.clientY - my;
od.style.left = parseInt(od.style.left) +mrx + "px";
od.style.top = parseInt(od.style.top) + mry + "px";
mx = e.clientX;
my = e.clientY;

function showBackground(obj,endInt)

obj.filters.alpha.opacity+=1;
if(obj.filters.alpha.opacity<endInt)

setTimeout(function()showBackground(obj,endInt),8);

</script>
这是相应的样式
<style type="text/css">

</style>
一下是引用的方法：
<div id="bodyL"> <a href="#" onclick = "show('fd',event);return false;"> 弹出提示</a> </div>
<div id="fd" style="display:none;filter:alpha(opacity=100);opacity:1;">
<div class="contentup"> <a href="#" class="od" onclick = "closeed('fd');return false;"> 关闭 </a>
<div id="tittleup">友情提示：</div>
<ul id="upcontent">
<li>对不起，您输入的数字超过有效范围。请输入100-200之间的数字，谢谢。</li>
</ul>
</div>
</div>

好了多的我就不说了，希望能对你有所启发。祝您成功！！！

</html>本回答被提问者采纳参考技术B 你这样写肯定麻烦啦~

你可以先做个DIV隐藏起来，在onsubmit里面判断是否合法，
不合法再显示那个DIV啊~

（当然，DIV里面的内容，你可以随便操作,这样的思路简单多了吧）参考技术C 百度不是有个POPUP.js可以用用

JavaScript JavaScript Popup Unobstrusive

function popup(url) {
  newWindow = window.open(url, 'name', 'height=400,width=335,scrollbars=yes');
  if (window.focus) { newWindow.focus() }
  return false;
}



// &lt;a href=&quot;link.html&quot; onclick=&quot;popup('link.html');&quot;&gt;Link&lt;/a&gt;

以上是关于javascript popup提示的主要内容，如果未能解决你的问题，请参考以下文章
