Question

protected void Button1_Click(object sender, EventArgs e)
{
    for (int i = 0; i < 100; i++)
    {
        Page.ClientScript.RegisterClientScriptBlock(GetType(), "myScript", "<script>alert('hello world');</script>");
    }
}

警报只执行一次，是否可以在迭代中每次都执行警报？

Answer 1

是的，将其更改为，注意“myScript”+ i，它会在每次迭代时更改密钥：

for (int i = 0; i < 100; i++)
        {
            Page.ClientScript.RegisterClientScriptBlock(GetType(), "myScript" + i, "<script>alert('hello world');</script>");
        }

Answer 2

我已经得到了解决方案，因此你必须在每个循环中更改密钥像：

Page.ClientScript.RegisterClientScriptBlock(GetType(), "myScript", "<script>alert('hello world');</script>");
        Page.ClientScript.RegisterClientScriptBlock(GetType(), "myScript1", "<script>alert('hello world');</script>");

如何在for循环代码中调用javascript？
