Question

在C# ASP.NET我有html 页面，其中有buttons （Button1，Button2 .. 。Button30）我想用循环禁用所有这些按钮，

喜欢Button [i] .enable = false

我该怎么做？我从我的数据库中读取了buttons的列表，我想要禁用那些（false）值。

protected void Page_Load(object sender, EventArgs e) {
    DataSet.seatsDataTable seatDT = new DataSet.seatsDataTable();
    DataSetTableAdapters.seatsTableAdapter seatTA = new DataSetTableAdapters.seatsTableAdapter();
    seatTA.FillByAllSeatID(seatDT);
    for(int i = 1; i < 29; i++) {
        seatTA.FillBySeatIDfromUser(seatDT, i);
        if (seatDT[0].SeatStatus == false) {
            reserved.Text += ( seatDT[0].SeatID.ToString() + ",") ;
            //Here i want to change button disable/enable status.
            //like Button[i].enabled=false
        }
    }
}

HTML CODE：

   <section id="banner">
 <table class="auto-style1" style="align-self: center">
                    <tr>
                        <td>
                            <input id="Button1" type="button" runat="server" value="1" onclick="disable(1)" /></td>
                        <td>
                            <input id="Button2" type="button" runat="server" value="2" onclick="disable(2)" /></td>

Answer 1

你需要

for (int i = 1; i < 10; i++) { Button b = this.FindControl("button" + i) as Button; if (b != null) b.Enabled = false; }。

using System.Web.UI.HtmlControls;

用于Html输入控件的Fix1和runat =＆＃34;服务器＆＃34;。

for (int i = 1; i < 10; i++) { HtmlInputButton b = this.FindControl("button" + i) as HtmlInputButton; if (b != null) b.Disabled = !b.Disabled; }

SELECT concat('TRUNCATE TABLE ', TABLE_NAME, ';')
FROM INFORMATION_SCHEMA.TABLES
WHERE TABLE_NAME in ('table1','table2','table3')

Answer 2

似乎所有按钮都在桌子内。

好的，我们禁用该表中的所有按钮。

首先在您的桌面上放置一个特定的ID，如下所示：

<table id="buttons-tbl" class="auto-style1" style="align-self: center">

然后，将此脚本放在表格的底部

<script type="text/javascript">
    $("#buttons-tbl input[type=button]").prop("disabled", true);
</script>

当然，您需要在html中包含jquery库

使用for循环禁用多个按钮（特定类型的循环并不重要）
