输入栏位清除 [英] Input field clear

问题描述

嗨
我以一种形式拥有100多个不同的输入字段.将所有输入数据插入数据库后.我应该清除所有输入字段，因为我要为每个输入字段分配空值，我认为将空值分配给100字段是一个漫长的过程.有没有清除所有输入字段的简单方法?

推荐答案

foreach (Control item in this.Controls)
{
    if (item is textBox)
    {
        (item as TextBox).Text = "";
    }
}

private void ClearTextBoxes(Control parent)
{
    if (parent is TextBox)
    {
        (item as TextBox).Text = "";
    }
    else
    {
        if (parent.Controls.Count > 0)
        {
            foreach (Control item in parent.Controls)
            {
                ClearTextBoxes(parent);
            }
        }
    }
}

像这样调用该方法:

Call that method like so:

foreach (Control item in this.Controls)
{
    ClearTextBoxes(item);
}

看看这个提示/技巧:

There are 3 ways mentioned in it that can be used to do the same. Pick the one you like.

您可以使用javascript.我不清楚，但form.clear()已用完.搜索.
