newwin.document.write('');// 93.返回 javascript:history.go(-2);// 94.将页面上选中的内容复制到剪贴板 abcdefg<input type='button'onclick="window.clipboardData.setData('text',document.selection.createRange().text);" value='复制页面选中的字符'>// 95.将页面上选中的内容复制到剪贴板<INPUT TYPE="text" NAME="">kjhkjhkhkj<INPUT TYPE="button" onclick="document.execCommand('Copy', 'false', null);">//// 96.鼠标移到下拉框时自动全部打开<select onmouseover="javascript:this.size=this.length" onmouseout="javascript:this.size=1"></select>// 97.获得本机的文件 var fso = new ActiveXObject("Scripting.FileSystemObject"); var f1 = fso.GetFile("C:\\bsitcdata\\ejbhome.xml"); alert("File last modified: " + f1.DateLastModified); // 98.判断客户端是否是IE浏览器 因为 document.all 是 IE 的特有属性，所以通常用这个方法来判断客户端是否是IE浏览器 ,document.all?1:0; 99.创建新的下拉框选项 new Option(text,value)这样的函数// 100.在页面上画柱状图<STYLE>td{font-size:12px}body{font-size:12px}v\:*{behavior:url(#default#VML);} //这里声明了v作为VML公用变量</STYLE><SCRIPT LANGUAGE="JavaScript">mathstr=12;
