后台重新调用
protected void Timer1_Tick(object sender, EventArgs e)
{
BindData();
System.Web.UI.ScriptManager.RegisterStartupScript(this.ScriptManager1, this.GetType(), "New", "../AlarmPop.js", true);
}
protected void Button3_Click(object sender, EventArgs e)
{
ScriptManager.RegisterStartupScript(this.UpdatePanel4, this.GetType(), "New", "../AlarmPop.js", true);
}
调用不成功 --------------------编程问答-------------------- 后台只好调用JS里的方法吧
不能直接调用JS吧
你把功能写JS方法里调用好了 --------------------编程问答-------------------- 會不會是你的路徑問題，比如說要加上文件夾名。 --------------------编程问答-------------------- 把JS文件换成直接写试试
<script>...</script> --------------------编程问答-------------------- 应该不是路径的问题
这个界面刚打开会调用一次JS文件，看到效果了
而且我把
<asp:Button ID="Button3" runat="server" OnClick="Button3_Click" Text="Button" />
按钮放在<asp:ScriptManager ID="ScriptManager1" runat="server" />
这个前面，然后点击按钮也会调用JS文件
但是这整个页面会闪一下，我加了AJAX是局部刷新的，放在AJAX外面程序正常的，放AJAX里面就不行了
--------------------编程问答-------------------- 有高人指点下吗 --------------------编程问答-------------------- 你仅仅是需要动态的加载一下JS文件？
http://blog.csdn.net/sgear/archive/2008/01/14/2043364.aspx --------------------编程问答-------------------- 是的，需要在重新调用JS文件 --------------------编程问答--------------------
6楼的可以.以前用过.好像也是找的那个 --------------------编程问答-------------------- 来人啊。。。。。 --------------------编程问答--------------------
怎么在后台调用
protected void Timer1_Tick(object sender, EventArgs e)
{
/////???????????
} --------------------编程问答-------------------- ScriptManager.RegisterStartupScript("<script language='javascript'>s1.src='test.js';</script>")
可以吗
--------------------编程问答-------------------- 难道你要这样？？？
.aspx
<HEAD>
<title>WebForm1</title>
<asp:placeholder id="myplaceholder" runat="server"></asp:placeholder>
</HEAD>
.cs
private void Button2_Click(object sender, System.EventArgs e)--------------------编程问答--------------------
{
System.Web.UI.Control a = Page.FindControl("myplaceholder");
System.Web.UI.HtmlControls.HtmlGenericControl objLink = new HtmlGenericControl("script");
objLink.Attributes.Add("language","javascript");
objLink.Attributes.Add("src","1.js");//这个地方你自己用变量控制
objLink=objLink;
a.Controls.Add(objLink);
}
<asp:placeholder id="myplaceholder" runat="server"></asp:placeholder>
这句不能放HEAD里
只能放body里，但是没出现效果 --------------------编程问答-------------------- 动态加载一个js文件即可 --------------------编程问答--------------------
ScriptManager.RegisterClientScriptBlock(this.UpdatePanel4, this.UpdatePanel4.GetType(), "New", "alert('弹出加载测试');", true);这个可以调出一个弹出框，我想加载下JS文件弄不出来，郁闷啊
ScriptManager.RegisterClientScriptBlock(this.UpdatePanel4, this.UpdatePanel4.GetType(), "New", "../AlarmPop.js", true);--------------------编程问答-------------------- 请问下如何写个javascript函数啊
<script language=javascript>
function ChangeSrc()
{
var Key = document.getElementById("SrcExample")
Key.src="../AlarmPop.js";//JS文件存放路径
return false;
}
然后在后台调用ChangeSrc函数
ScriptManager.RegisterStartupScript(this, GetType(), "New", " <script language= 'javascript'>ChangeSrc() </script> ", true);
补充：.NET技术 , ASP.NET
