页面加载两次由于JS code [英] page loads twice due to js code

问题描述

我有一个中继器，在这里我设置类，里面的onmouseover和onmouseout从背后code性能本格：

I have this div inside a repeater, where i set the class, onmouseover and onmouseout properties from code behind:

<div id="Div1" runat="server" class="<%# getClassProduct(Container.ItemIndex) %>" onmouseover="<%# getClassProductOver(Container.ItemIndex) %>" onmouseout="<%# getClassProductOut(Container.ItemIndex) %>">

codebehind：

codebehind:

 public String getClassProduct(Object index)
{
    int indexItem = Int32.Parse(index.ToString());
    if (indexItem == 3)
        return "produs_box produs_box_wrap overitem lastbox";
    else
        return "produs_box produs_box_wrap overitem";
}

public String getClassProductOver(Object index)
{
    int indexItem = Int32.Parse(index.ToString());
    if (indexItem == 3)
        return "this.className='produs_box produs_box_wrap overitem_ lastbox'";
    else
        return "this.className='produs_box produs_box_wrap overitem_'";
}

public String getClassProductOut(Object index)
{
    int indexItem = Int32.Parse(index.ToString());
    if (indexItem == 3)
        return "this.className='produs_box produs_box_wrap overitem lastbox'";
    else
        return "this.className='produs_box produs_box_wrap overitem'";
}

那么，问题是，我的Page_Load被激发两次，并有我有一些code，我想只执行一次：

Well, the problem is that, my Page_Load is fired twice, and there i have some code which i want to execute only ONCE:

 if (!Page.IsPostBack)
    { ..code to execute once }

这code最初发射，并在页面呈现之后，它被再次调用，并执行再次，由于该js的...

This code is fired initially, and after the page is rendered, it is called again, and executed again due to that js...

任何人都可以推荐一个解决方法吗？

Anyone can recommend a workaround?

先谢谢了。

更新：只发生在Firefox。在Chrome，它工作正常...

UPDATE: happens only in Firefox. On chrome, it works fine...

解决方案：停用YSlow的....只是可怕

"Solution": deactivated YSlow....just "horrible".

推荐答案

您可以使用<一个href=\"http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.repeater.itemcreated%28v=VS.90%29.aspx\"相对=nofollow> OnItemCreated 事件来做到这一点？

Can you use OnItemCreated event to do that?

假设，在div是每个项目的一部分，你可以捕获到事件＆放大器;做一个的FindControl 在项目来获取句柄到 DIV 。检查的ItemIndex ＆安培;如您在code-背后需要分配类。

Assuming, the div is part of each item, you could trap into the event & do a FindControl on the Item to get the handle to div. Check for ItemIndex & assign the class as you need to in code-behind.

这是否帮助呢？
