//区域打印方式二：仅仅打印标签部分 function printTag2() { bdhtml = window.document.body.innerHTML; sprnstr = "<!--startprint-->";//开始标记 eprnstr = "<!--endprint-->";//结束标记 prnhtml = bdhtml.substr(bdhtml.indexOf(sprnstr) + 17); prnhtml = prnhtml.substring(0, prnhtml.indexOf(eprnstr)); window.document.body.innerHTML = prnhtml; window.print(); }
