实现功能:弹出一个DIV层提示等待信息,这个时候禁用用户操作页面中的其他内容。 弹出DIV: < div id ="divWaiting" style ="display: none; z-index: 1100; left: 25%; right: 25%; position: absolute; text-align: center; width: 50%; height: 50px; border-right: #009900 1px solid; border-top: #009900 1px solid; border-left: #009900 1px solid; border-bottom: #009900 1px solid; background-color: #f9fff6; left: expression((this.offsetParent.clientWidth/2)-(this.clientWidth/2)+this.offsetParent.scrollLeft); top: expression((this.offsetParent.clientHeight/2)-(this.clientHeight/2)+this.offsetParent.scrollTop);" > < br > The system is dealing with your request, please waiting </ div > 弄一个全屏的DIV来覆盖页面: < div id ="divDisable" style ="display: none;width:expression(document.body.offsetWidth);height:expression(document.body.offsetHeight); z-index: 1000; position: absolute;left: 0px; top: 0px;filter:alpha(opacity=50); background-color:White" ></ div > 点击按钮的操作: document.getElementById("divWaiting").style.display=""; document.getElementById("divDisable").style.display=""; 其他处理: function ChangeDiv(){ document.getElementById("divDisable").style.height=document.body.offsetHeight+document.body.scrollTop;}window.onscroll=ChangeDiv; 转载于:https://www.cnblogs.com/qqflying/archive/2008/02/16/1070799.html
