webform在指定的div中添加动态添加label，该怎么解决

Question

如题所述

Answer 1

动态生成Asp.Net服务器控件，并取其值

C# codeprivate void LoadProperty(int cateId)
｛

HtmlGenericControl span = new HtmlGenericControl();
for (int i = 0; i < ds.Tables[0].Rows.Count; i++)
{
StringBuilder strHtml = new StringBuilder();
if (i % 2 == 0)
{
strHtml.Append("<div >");

strHtml.Append("<div class=\"layout1\">");
}
else
{
strHtml.Append("<div >");
}

TextBox txt = new TextBox();
Label lbl = new Label();
HiddenField hdf = new HiddenField();//
lbl.ID = "lblProp" + i.ToString();
lbl.Text = ds.Tables[0].Rows[i]["PropName"].ToString() + ":";
txt.ID = "txtProp" + i.ToString();

hdf.ID = "hdfProp" + i.ToString();//

lbl.EnableViewState = true;
txt.EnableViewState = true;
hdf.EnableViewState = true;//

LiteralControl lc = new LiteralControl(strHtml.ToString());

lc.EnableViewState = true;

span.Controls.Add(lc);
span.Controls.Add(lbl);
span.Controls.Add(txt);
span.Controls.Add(hdf);//
if (i % 2 == 0)
{
span.Controls.Add(new LiteralControl("</div></div>"));
}
else
{
span.Controls.Add(new LiteralControl("</div>"));
}
}
｝

动态生成的控件，当点击页面按钮时会刷新页面，所以，生成控件的方法不需要

if(!IsPostBack)
{
}
------解决方案--------------------
JScript code$(function(){
$("#addLabel").click(function(){
$("#divAddLabel").append("<label>添加的label<label/><br />");
});
});
