修复asp.net中文本框的大小

问题描述

<asp:TextBox ID=txtComments runat="server" BorderColor="Gray"
           BorderStyle="Solid" BorderWidth="1px" CausesValidation="true" Wrap="true"
           MaxLength="100"
           TextMode="MultiLine"
           Width="350px">

在aspx.cs文件中

in aspx.cs file

public int MaxLength
   {
       get { return txtComments.MaxLength; }
       set { txtComments.MaxLength = value; }
   }
   public void wordCount()
   {
       txtCount.Text = txtComments.MaxLength.ToString();
       txtComments.Attributes.Add("onKeyUp", "javascript:document.getElementById(''" + txtCount.ClientID + "'').setAttribute(''value'', (" + txtComments.MaxLength + " - parseInt(document.getElementById(''" + txtComments.ClientID + "'').getAttribute(''value'').length)));");

   }

推荐答案

focus()
onKeyUp() //(after all other code)
onMouseUp()

并将光标设置到末尾只需执行以下操作:

this.value = this.value;在javascript事件中，因为这会将(框内的)文本设置为自身，从而迫使光标重置到末尾.

and to set the cursor to the end simply do:

this.value = this.value; in the javascript event as this will set the text (of the box) to itself thus forcing the cursor to be reset to the end.
