如何添加动态文本框的HTML输入的地方 [英] How to add dynamic textbox in the place of html input

问题描述

我不得不以字符串格式生成一个表，并在体内

加入

 字符串中间=＆LT; TR类='cart_item'＆gt;中+＆LT; TD类=产品删除＆gt;中+

                          ＆LT;'？handler.ashx ID = + ID + A HREF ='级=删除标题=删除此项目＆GT;＆安培;倍;＆LT; / A＆gt;中+

                          ＆所述; / TD＆gt;中+

                      ＆LT; TD类='产品缩略图＆gt;中+
                      ＆所述; A HREF ='StoreDetails.aspx的id =？+ ID +'＆gt;中+
              ＆LT; IMG SRC ='+拇指+'+
              类='依恋shop_thumbnail WP-后映像ALT =+ PNAME +/＆GT;＆LT; / A＆GT;＆LT; / TD＆gt;中+

                      ＆LT; TD类=产品名称＆gt;中+
                      ＆所述; A HREF =？StoreDetails.aspx的id =+ ID +'＆gt;中+ pname中+＆所述; / a取代;＆所述; / TD＆gt;中+

                      ＆LT; TD类=产品价格＆gt;中+
                      ＆LT;跨度类='量'＆GT;＆LT;我类='图标INR'＆GT;＆LT; / I＆GT;+ cd.packsize +＆LT; / SPAN＆GT;＆LT; / TD＆gt;中+

                      ＆LT; TD类=产品价格＆gt;中+
                      ＆LT;跨度类='量'＆GT;＆LT;我类='图标INR'＆GT;＆LT; / I＆GT;+价格+＆LT; / SPAN＆GT;＆LT; / TD＆gt;中+

                      ＆LT; TD类='产品数量'＆gt;中+
                      ＆LT; D​​IV CLASS ='数量buttons_added'＆GT​​;＆LT;输入值=' - '级='减'的类型='按钮'＆gt;中+

                  ＆LT;输入步骤='1'分='1'的名字=数量值='+数量+标题='数量'级=输入文字数量文本'ID ='txtqty+ CD。 ID +大小=4型=文本＆gt;中+
 

先在这里，我已经添加了输入 TYPE =文本在HTML中，但现在我想补充asp.net文本框控件

 ＆LT;输入值='+'级='加'类型='按钮'＆GT;＆LT; / DIV＆gt;中+
            //数量+

                          ＆所述; / TD＆gt;中+

                          ＆所述; TD类='产物的小计'＆gt;中+
                          ＆LT;跨度类='量'＆GT;＆LT;我类='图标INR'＆GT;＆LT; / I＆GT;+（Convert.ToDouble（价）*数量）+＆LT; / SPAN＆GT;＆LT; / TD＆gt;中+
                      ＆所述; / TR＆gt;中;




       // INT数量=（（词典＆LT; INT，INT＆GT;）会议[购物车]）[ID]

          cartInfo.InnerHtml + =中间;
 

解决方案

取要绘制表占位符的控制。

在你的ASPX文件：

 ＆LT; ASP：占位符ID =PH=服务器/＆GT;
 

在后面ASPX.CS文件code：

 文字loLit1 =新的文字（）;
    loLit1.Text =字符串的数量文本框上面的;

    ph.Controls.Add（loLit1）;

    文本框loTxt =新文本框（）;
    loTxt.Attributes.Add（步骤，1）;
    loTxt.Attributes.Add（最小，1）;
    loTxt.Attributes.Add（名，量）;
    loTxt.Text =10;
    loTxt.ToolTip =数量;
    loTxt.ID =txtqty;

    ph.Controls.Add（loTxt）;

    文字loLit2 =新的文字（）;
    loLit2.Text =字符串的数量文本框后;
    ph.Controls.Add（loLit2）;
 

I had generate a table in a string format and added in the body

string mid = "<tr class='cart_item'>" +  "<td class='product-remove'>" +

                          " <a href='handler.ashx?id=" + id + "' class='remove' title='Remove this item'>&times;</a>" +

                          "</td>" +

                      " <td class='product-thumbnail'>" +
                      "     <a href='StoreDetails.aspx?id=" + id + "'>" +
              "<img src='" + thumb + "' " +
              "class='attachment-shop_thumbnail wp-post-image' alt='" + pname + "' /></a>                   </td>" +

                      " <td class='product-name'>" +
                      "     <a href='StoreDetails.aspx?id=" + id + "'>"+pname+"</a>                 </td>" +

                      " <td class='product-price'>" +
                      "     <span class='amount'><i class='icon-inr'></i> " + cd.packsize + "</span>                    </td>" +

                      " <td class='product-price'>" +
                      "     <span class='amount'><i class='icon-inr'></i> " + price + "</span>                  </td>" +

                      " <td class='product-quantity'>" +
                      "        <div class='quantity buttons_added'><input value='-' class='minus' type='button'>" +

                  "<input step='1' min='1' name='quantity' value='" + qty + "' title='Qty' class='input-text qty text ' id='txtqty" + cd.id+"' size='4' type='text'>" +

first here, I have added the input type="text" in html, but now I want to add asp.net textbox control

"<input value='+' class='plus' type='button'></div>" +
            //   qty +

                          "</td>" +

                          "<td class='product-subtotal'>" +
                          " <span class='amount'><i class='icon-inr'></i>  " + (Convert.ToDouble(price) * qty) + "</span>                   </td>" +
                      "</tr>";




       //   int qty = ((Dictionary<int, int>)Session["cart"])[id];

          cartInfo.InnerHtml += mid;

解决方案

Take a PlaceHolder control where you want to render table.

In your ASPX file:

<asp:PlaceHolder ID="ph" runat="server" />

In code behind ASPX.CS file:

Literal loLit1 = new Literal();
    loLit1.Text = "String above the Quantity Textbox";

    ph.Controls.Add(loLit1);

    TextBox loTxt = new TextBox();
    loTxt.Attributes.Add("step", "1");
    loTxt.Attributes.Add("min", "1");
    loTxt.Attributes.Add("name", "quantity");
    loTxt.Text = "10";
    loTxt.ToolTip = "Qty";
    loTxt.ID = "txtqty";

    ph.Controls.Add(loTxt);

    Literal loLit2 = new Literal();
    loLit2.Text = "String After the Quantity Textbox";
    ph.Controls.Add(loLit2);
