jquery/js 实现 标签 条码 一维码 Web页面 区域打印解决方案 实例//打印页面区域方式一:给body添加visibility:hidden;隐藏标记,给要打印的部分添加visibility:visible;显示标记function printTag1(){$("#entityForm").css("display","none");$("#tagImgView").css("display","block");window.print();$("#entityForm").css("display","block");}//区域打印方式二：仅仅打印标签部分function printTag2() { bdhtml = window.document.body.innerHTML; sprnstr = "<!--startprint-->";//开始标记 eprnstr = "<!--endprint-->";//结束标记 prnhtml = bdhtml.substr(bdhtml.indexOf(sprnstr) + 17); prnhtml = prnhtml.substring(0, prnhtml.indexOf(eprnstr)); window.document.body.innerHTML = prnhtml; window.print();}<form action="" name="entityForm" id="entityForm" target="result"method="post" onsubmit="return checkInfo();"><input type="hidden" name="id" id="id" value="${tag.id }" /><table border="0" cellpadding="0" cellspacing="0"><tr class="main_info"><td colspan="4"><div id="receipt_title"class="receipt_main_title">一维标签管理</div></td></tr><tr class="info"><!-- <th>标签名称:</th><td><input type="text" name="name" id="name" class="input_txt"value="${tag.name }" /></td>--><th>标签编号:</th><td><input type="text" name="code" id="code" onkeyup="value=value.replace(/[\W]/g,'')" onbeforepaste="clipboardData.setData('text',clipboardData.getData('text').replace(/[^\d]/g,''))" class="input_txt" value="${tag.code }" /></td><td colspan="2"></td></tr><tr class="info"><td colspan="1"></td><td colspan="2"><a href="javascript:createTag();"id="createTag" class="myBtn"><em>生成标签</em> </a> <ahref="javascript:saveTag();" id="saveTag" class="myBtn"><em>保存标签</em></a></td><td colspan="1"></td></tr><tr class="info"><td colspan="2">标签预览:</td><td colspan="2"><a href="javascript:printTag1();"id="printTag" class="myBtn"><em>打印标签</em> </a> </td></tr></table></form><div id="preview"><div class="info"><!--startprint--><img id="tagImgView" class="PrintOnly"src="${ctx }/tag/barcode?msg=12345678&encode=utf-8&type=code39" /><!--endprint--></div></div>条码生成采用的开源jar包：barcode4j
