如何停止重新加载页面点击按钮时？ [英] How to stop to reload page when click the button?

问题描述

我有asp.net网站，其中包括按钮一些计算。当我preSS的按钮，我的计算工作正常，但首先网页正在刷新，然后计算看起来在标签上。我想这样做，计算看起来在标签上直接。而无需刷新。我给一些codeS。

P.S。此外Page_Load中具有接收每日汇率的函数

ASP

 ＆LT; ASP：按钮的ID =Button1的=服务器背景色=＃990000
 BORDERCOLOR =＃333333前景色=白的onclick =的button1_Click文本=计算
 WIDTH =85px边框​​=开端的风格=保证金左：20像素
 的ValidationGroup =grup1/＆GT;
 

按钮单击

 保护无效的button1_Click（对象发件人，EventArgs的发送）
{
双sayi1，sayi2，sayi3，hesap，sonuc;sayi1 = Convert.ToDouble（Tb1.Text）;
sayi2 = Convert.ToDouble（Tb2.Text）;
sayi3 = Convert.ToDouble（Tb3.Text）;
如果（Tb1.Text.Contains（。）|| Tb2.Text.Contains（。）|| Tb3.Text.Contains（。））
{
  ...
  ...
  ...
 

解决方案

使用Ajax的。如果没有，你总是会调用回发事件。或在另一方面做一些客户端编程的JavaScript。

I have asp.net website which include some calculation on button. When I press the button, my calculation works fine but, firstly page is refreshing and then the calculation looks on the label. I want to do that calculation looks on the label directly. Without refreshing. I give some codes.

p.s. Also Page_Load has a function that receives daily exchange rates

ASP

<asp:Button ID="Button1" runat="server" BackColor="#990000" 
 BorderColor="#333333" ForeColor="White" onclick="Button1_Click" Text="Calculate" 
 Width="85px" BorderStyle="Outset" style="margin-left: 20px" 
 ValidationGroup="grup1" />

BUTTON CLICK

protected void Button1_Click(object sender, EventArgs e)
{
double sayi1, sayi2, sayi3, hesap, sonuc;

sayi1 = Convert.ToDouble(Tb1.Text);
sayi2 = Convert.ToDouble(Tb2.Text);
sayi3 = Convert.ToDouble(Tb3.Text);


if (Tb1.Text.Contains(".") || Tb2.Text.Contains(".") || Tb3.Text.Contains("."))
{
  ...
  ...
  ...

解决方案

Use Ajax. If not you will always invoke a postback event. Or on the other hand do some client side programming with javascript.
