打印列表框内容 [英] Print Listbox contents

问题描述

大家好

 功能 driverprint()
{
   var  textboxText = 文档 .getElementById(' <％= TextBox1.ClientID％>');
   var  ListBox1 = 文档 .getElementById(' <％= ListBox1.ClientID％>');
   var  windowUrl = '  about:空白' ;
   var  windowName = ' 打印' + 新
  日期().getTime();
   var  printWindow = 窗口 .open(windowUrl，windowName，'   left = 50000，top = 50000，width = 0，height = 0')；
  printWindow.文档 .write(textboxText.value);
  printWindow.文档 .write(ListBox1.value);

  printWindow. document  .close();
  printWindow.focus();
  printWindow.print();
  printWindow.close();
} 

正在打印文本框和列表框内容，现在问题是未打印ListBox1.value，我该如何解决?

解决方案

根据 http://codeabout.wordpress.com/2010/12/27 /print-from-a-listbox-using-c/ [function driverprint() { var textboxText = document.getElementById('<%= TextBox1.ClientID %>'); var ListBox1 = document.getElementById('<%= ListBox1.ClientID %>'); var windowUrl = 'about:blank'; var windowName = 'Print' + new Date().getTime(); var printWindow = window.open(windowUrl, windowName, 'left=50000,top=50000,width=0,height=0'); printWindow.document.write(textboxText.value); printWindow.document.write(ListBox1.value); printWindow.document.close(); printWindow.focus(); printWindow.print(); printWindow.close(); }

Am printing textbox and listbox contents, Now problem is ListBox1.value is not printed,How can i solve this?

解决方案

According to the documentation[^] the ListBox does not contain a Value property.

There''s a tutorial here, it solved my problem last year.
