各类常用代码 1、JavaScript分割字符方法 数组 = 字符串.split(“分割字符”); 2、使用JavaScript为ListBox赋值 var listbox = document.getElementById(listAccount); var option = document.createElement(OPTION); option.value = 1; option.text =ABC; listbox.add(option); 3、删除ListBox中的项 function del(){?? ??? var objdel=document.getElementById(ListBox的ID);?? ??? for(var i=objdel.options.length-1;i=0;i--)?? ??? {?? ??????? if(objdel.options[i].selected)?? ??????? {?? ??????????? objdel.remove(i);?? ??????? }?? ??? }?? } 4、获取CheckBoxList的选择项的值 function GetCheckBoxListValue(objID) { var v = new Array(); var CheckBoxList = document.getElementById(objID); if(CheckBoxList.tagName == TABLE) { for(i=0;iCheckBoxList.rows.length;i++) for(j=0;jCheckBoxList.rows[i].cells.length;j++) if(CheckBoxList.rows[i].cells[j].childNodes[0]) if(CheckBoxList.rows[i].cells[j].childNodes[0].checked==true) v.push(CheckBoxList.rows[i].cells[j].childNodes[1].innerText); } if(CheckBoxList.tagName == SPAN) { for(i=0;iCheckBoxList.childNodes.length;i++) if(CheckBoxList.childNodes[i].tagName == INPUT) if(CheckBoxList.childNodes[i].checked==true) { i++; v.push(CheckBoxList.childNodes[i].innerText); } } return v; } 5、把Repeater中的数据导出到Excel protected void btnPrint_Click(object sender, EventArgs e) { System.IO.StringWriter sw = new System.IO.StringWriter(); System.Web.UI.HtmlTextWriter hw = new System.Web.UI.HtmlTextWriter(sw); this.Repeater1.RenderControl(hw); Response.Clear(); Response.ContentType = application/vnd.ms-excel; Response.Charset = ; Page.EnableViewState = false; Response.AppendHeader(Content-Disposition, attachment;filename=baomingbiao.xls); Response.Write(htmlheadmeta http-equiv=Content-Type content=\text/html;
