MOUSE OVER事件在asp.net c＃ [英] MOUSE OVER event in asp.net c#

问题描述

我有一个名为label 4的标签我想在我的c＃中写一个MouseOver事件，这是一个Web应用程序。

  protected   void  Label4_MouseOver（ object  sender，EventArgs e）
 {
 Label4.Visible =  false ; 
} 

这是我的代码不能正常工作请告诉我问题

解决方案

In web，你应该使用客户端活动。



尝试：

 Label4.Attributes.Add（< span class =code-string>  onmouseover，  SomeJavaScriptFunction（）;）; 

此行将向鼠标悬停标签添加客户端事件。您可以使用此方法在鼠标上编写逻辑。

试试这个：

.aspx文件：

 <  脚本   < span class =code-attribute> type   =  Javascript >  
  function  visible（）
 {
  document  .getElementById（  Label4）。visible = 假; 
} 
 <   /  脚本 >  
 <   asp：label     id   =  Label1    runat   =  server    text   =  Hiiii Prashant    onmouseover   =  visible（） ; >  <   / asp：label  >  
 <   asp：label     id   =  Label4    runat   =  server    text   =  Hiiii Prashant >  <   / asp：label  >

I have an label named label 4 I want to write an MouseOver event in my c# which is an web application.

protected void Label4_MouseOver(object sender, EventArgs e)
{
    Label4.Visible = false;
}

Here is my code its not working please say me the problem

解决方案

In web, you should use client side event.

Try:

Label4.Attributes.Add("onmouseover","SomeJavaScriptFunction();");

This line would add a client side event to mouse over of the label. You can write your logic on mouse over in this method.

Try this:
.aspx file:

<Script type="Javascript">
function visible()
{
    document.getElementById("Label4").visible = false;
}
</script>
 <asp:label id="Label1" runat="server" text="Hiiii Prashant" onmouseover="visible();"></asp:label>
 <asp:label id="Label4" runat="server" text="Hiiii Prashant"></asp:label>
