• JS实现 页面提交防刷新等待提示


     1 //关闭等待窗口  
     2 function closediv() {  
     3     //Close Div   
     4     document.body.removeChild(document.getElementById("bgDiv"));  
     5     document.getElementById("msgDiv").removeChild(document.getElementById("msgTitle"));  
     6     document.body.removeChild(document.getElementById("msgDiv"));  
     7 }  
     8 //显示等待窗口  
     9 function showdiv(str) {  
    10     var msgw, msgh, bordercolor;  
    11     msgw = 400; //提示窗口的宽度   
    12     msgh = 100; //提示窗口的高度   
    13     bordercolor = "#336699"; //提示窗口的边框颜色   
    14     titlecolor = "#99CCFF"; //提示窗口的标题颜色   
    15   
    16     var sWidth, sHeight;  
    17     sWidth = window.screen.availWidth;  
    18     sHeight = window.screen.availHeight;  
    19   
    20     var bgObj = document.createElement("div");  
    21     bgObj.setAttribute('id', 'bgDiv');  
    22     bgObj.style.position = "absolute";  
    23     bgObj.style.top = "0";  
    24     bgObj.style.background = "#777";  
    25     bgObj.style.filter = "progid:DXImageTransform.Microsoft.Alpha(style=3,opacity=25,finishOpacity=75";  
    26     bgObj.style.opacity = "0.6";  
    27     bgObj.style.left = "0";  
    28     bgObj.style.width = sWidth + "px";  
    29     bgObj.style.height = sHeight + "px";  
    30     document.body.appendChild(bgObj);  
    31     var msgObj = document.createElement("div")  
    32     msgObj.setAttribute("id", "msgDiv");  
    33     msgObj.setAttribute("align", "center");  
    34     msgObj.style.position = "absolute";  
    35     msgObj.style.background = "white";  
    36     msgObj.style.font = "12px/1.6em Verdana, Geneva, Arial, Helvetica, sans-serif";  
    37     msgObj.style.border = "1px solid " + bordercolor;  
    38     msgObj.style.width = msgw + "px";  
    39     msgObj.style.height = msgh + "px";  
    40     msgObj.style.top = (document.documentElement.scrollTop + (sHeight - msgh) / 2) + "px";  
    41     msgObj.style.left = (sWidth - msgw) / 2 + "px";  
    42     var title = document.createElement("h4");  
    43     title.setAttribute("id", "msgTitle");  
    44     title.setAttribute("align", "right");  
    45     title.style.margin = "0";  
    46     title.style.padding = "3px";  
    47     title.style.background = bordercolor;  
    48     title.style.filter = "progid:DXImageTransform.Microsoft.Alpha(startX=20, startY=20, finishX=100, finishY=100,style=1,opacity=75,finishOpacity=100);";  
    49     title.style.opacity = "0.75";  
    50     title.style.border = "1px solid " + bordercolor;  
    51     title.style.height = "18px";  
    52     title.style.font = "12px Verdana, Geneva, Arial, Helvetica, sans-serif";  
    53     title.style.color = "white";  
    54     //title.style.cursor = "pointer";  
    55     //title.innerHTML = "关闭";  
    56     //title.onclick = closediv;  
    57     document.body.appendChild(msgObj);  
    58     document.getElementById("msgDiv").appendChild(title);  
    59     var txt = document.createElement("p");  
    60     txt.style.margin = "1em 0"  
    61     txt.setAttribute("id", "msgTxt");  
    62     txt.innerHTML = str;  
    63     document.getElementById("msgDiv").appendChild(txt);  
    64 }  
    65 //屏蔽F5  
    66 document.onkeydown = mykeydown;  
    67 function mykeydown() {  
    68     if (event.keyCode == 116) //屏蔽F5刷新键     
    69     {  
    70         window.event.keyCode = 0;  
    71         return false;  
    72     }  
    73 }  

    使用页面直接调用这个js文件,然后在按钮的onclick事件中填写:

    <INPUT onclick="showdiv('表达数据提交中<br/>请稍候........ <br/> );"  type="button"  value="提交数据">

    调用closediv()关闭
