//剔除不需要打印的部分
            function Contrarypreview() {

    已测试

function print4() \{  
var headhtml = document.getElementById(“head”).innerHTML;  
//alert(headhtml);  
var headstr = “” + headhtml + ““;  
var footstr = ““;  
var printData = document.getElementById(“dvData”).innerHTML; //获得 div 里的所有 html 数据  
var oldstr = document.body.innerHTML;  
document.body.innerHTML = headstr + printData + footstr;  
//window.print();  
document.execCommand(“print”);  
//document.body.innerHTML = oldstr;  
return false;  
\}

function print2() \{  
document.execCommand(“print”);  
\}  
function print3() \{  
window.print();  
\}

----------

function print5() \{  
(‘\#Div1’).attr(“style”,”display:none;”);  
document.execCommand(“print”);(‘\#Div1’).attr(“style”, “display:block;”);
