Question

我尝试过以下代码，但整个页面显示的是空白内容 1）HTML身体属性的粘贴

<script language="JavaScript">
function printPage() {
if(document.all) {
document.all.divButtons.style.visibility = 'hidden';
window.print();
document.all.divButtons.style.visibility = 'visible';
} else {
document.getElementById('divButtons').style.visibility = 'hidden';
window.print();
document.getElementById('divButtons').style.visibility = 'visible';
}
}
</script>

2）htp.p('<div id="divButtons" name="divButtons">' ); htp.p('</div>' );
3）htp.p('<input type="button" value = "Print" onclick="printPage()" style="font:bold 11px verdana;color:#FF0000;background-color:#FFFFFF;">' );

这里有PLSQL动态内容代码:::

FROM  add_payment a,menu_item m

但是当点击按钮时，空白内容如下图所示::

看起来你真的不顾一切，并手动编写很多开箱即用的东西。
