遍历页面控件的几种方法
作者:admin 日期:2007-12-06
方法一:javascript法
function btnClear()
{
for(i=0;i<document.forms[0].elements.length;i++)
{
e=document.forms[0].elements;
if(e.type=='text'||e.type=='textarea')
{
e.value="";
}
}
return false;
}
在Onclick OnFocus OnLoad等事件中引用就行
方法二:Foreach遍历
foreach(Control ctl in this.Page.Controls[1].Controls)
{
if(ctl.GetType() == typeof(TextBox))
{
TextBox t = (TextBox) ctl;
t.Text = string.Empty;
}
方法三:
#region 清空指定页面上所有的控件内容,public static void ClearAllContent()
/// <summary>
/// 清空指定页面上所有的控件内容,包括TextBox,CheckBox,CheckBoxList,RadioButton,RadioButtonList。但是不清
/// 除如ListBox,DropDownList,因为这样的控件值对当前页面来说还可以用,一般这些控件里都是保存的字典数据。
/// Author:Kevin
/// 日期:2004-12-02
/// </summary>
/// <param name="page"> 指定的页面</param>
public static void ClearAllContent(System.Web.UI.Control page)
{
int nPageControls = page.Controls.Count;
for (int i = 0; i < nPageControls; i++)
{
foreach (System.Web.UI.Control control in page.Controls[i].Controls)
{
if (control.HasControls())
{
ClearAllText(control);
}
else
{
if (control is TextBox)
(control as TextBox).Text = "";
if (control is CheckBox)
(control as CheckBox).Checked = false;
if (control is RadioButtonList)
(control as RadioButtonList).SelectedIndex = -1;
if (control is RadioButton)
(control as RadioButton).Checked = false;
if (control is CheckBoxList)
{
foreach (ListItem item in (control as CheckBoxList).Items)
{
item.Selected = false;
}
}
}//if..else
}//foreach
}//for
}
#endregion
方法四:
建立一个类,用于存放那些TextBox的name和value ,代码如下:
Public Class UtilityObj
Private _name As String
Private _value As String
Public Sub New(ByVal Name As String, ByVal Value As String)
_name = Name
_value = Value
End Sub &a...[/i]
function btnClear()
{
for(i=0;i<document.forms[0].elements.length;i++)
{
e=document.forms[0].elements;
if(e.type=='text'||e.type=='textarea')
{
e.value="";
}
}
return false;
}

{

TextBox t = (TextBox) ctl;
t.Text = string.Empty;
