- 我正在编写我的第一个asp.net网站
- 以便在iPhone Safari上运行。
我的default.aspx正文中的代码:
<div id="pnlLogin" class="panel" selected="true" >
<h2>Login Details</h2>
<form ID="fLogin" runat="server" class="panel" selected="true" >
<fieldset>
<div class="row">
<label>Name</label>
<asp:TextBox id="txtUserName" runat="server" placeholder="Your username" />
</div>
<div class="row">
<label>Password</label>
<asp:TextBox id="txtPassword" textmode="Password" runat="server" placeholder="Your password" />
</div>
</fieldset>
<asp:LinkButton id="btnLogin" class="whiteButton" text="Log me in!" runat="server" onclick="Login_Clicked" />
</form>
</div>
在 default.aspx 的后端 .cs 文件中:
protected void Login_Clicked(object sender, EventArgs e)
{
var username = txtUserName.Text;
var password = txtPassword.Text;
if (username == "masi" && password == "pass")
{
Response.Redirect("ControlPanel.aspx");
}
}
来自桌面Safari的完整页面源代码:

</form>
</div>

</html>
问题:
在桌面版的Safari/Chrome上运行良好,我键入masi/pass并按下按钮,然后跳转到新页面,但在iPhone上,它会在控制台中给我一个Javascript错误,什么也不做。
它说: Javascript:错误 未定义 引用错误:找不到变量:__doPostBack
我完全不知道该怎么办。
更新-解决方案:我随机删除了头部中几乎无效的javascript代码,现在它可以正常工作了。
