网页标题更改

Question

我正在做一些改变，我们的网站，并刚刚添加了一个复选框列表，这是很好的工作，但我需要标题的网页改变，当我选择多个复选框。目前，如果没有选择，它会写成“…摘要”)。“然后，当您选择一个复选框时，它会写成“…摘要”“当选中多个复选框时，我需要它说”…摘要“.(多)“我在aspx.cs中找到了以下代码：

public partial class _default : PortalReportPage
{
    public int RegionId { get; set; }
    public List<int> SelectedRegions { get; set; }
    public GroupStatisticCollection Stats { get; set; }
    public CompanyRegionCollection Regions { get; set; }
    public int PropertyCount { get; set; }

    protected override void BindPath()
    {
        PagePath = PortalPath.GetBasicPath();
        PagePath.AddNode(Container.Name, "~/company/default.aspx?id=" + Container.NodeId);
        PagePath.AddNode("Reports", "~/company/reports.aspx?id=" + Container.NodeId);
    }

    protected void Page_Load(object sender, EventArgs e)
    {
        // Get all Selected regions into the SelectedRegions variable...
        SelectedRegions = GetArrayFromQueryString<Int32>("region").ToList();

        // TODO: remove this when the sole RegionId is ready to be replaced by the SelectedRegions list
        if (SelectedRegions.Count > 0)
        {
            RegionId = SelectedRegions.First();
        }
        else
        {
            RegionId = 0;
        }

        GetStatistics();

        if (!Page.IsPostBack)
        {
            this.Regions = CompanyRegionCollection.GetRegions(Container.NodeId);

            if (this.Regions != null && this.Regions.Count > 0)
            {
                if (this.RegionId == 0)
                {
                    this.PropertyCount = Regions.Sum(r => r.PropertyCount);
                }
                else
                {
                    if (this.Regions.Any(r => r.NodeId == RegionId))
                    {
                        this.PropertyCount = Regions.First(r => r.NodeId == RegionId).PropertyCount;
                    }
                }
            }

            if (this.PropertyCount == 0)
            {
                if (this.Regions.Count == 0)
                {
                    this.PropertyCount = PropertyList.GetProperties(PropertyCriteria.NewCriteria(Container.NodeId, PropertyCriteriaSubject.Company)).TotalRecords;
                }
            }

            BindOptionsPanel();
        }

        this.Title = "Summary for " + Container.Name;

        if (RegionId != 0)
        {
            try
            {
                this.Title += string.Format(" ({0})", NodeBasic.GetNodeBasic(RegionId).Name);
            }
            catch
            {

            }
        }
    }

    private void GetStatistics()
    {
        Stats = GroupStatisticCollection.GetCategoryStatistics(Container.NodeId, SelectedRegions);
    }

    private void BindOptionsPanel()
    {
        RegionsChecklist.Items.Add(new ListItem(" All", "0"));

        foreach (var region in Regions.OrderBy(r => r.Name))
        {
            var item = new ListItem(region.Name, region.NodeId.ToString());

            if (SelectedRegions.Contains(region.NodeId))
            {
                item.Selected = true;
            }

            RegionsChecklist.Items.Add(item);
        }
    }

    protected void ExportButton_Click(object sender, EventArgs e)
    {
        ExportToCsv(this.Stats, this.Title);
    }

    protected void RefreshButton_Click(object sender, EventArgs e)
    {
        var url = "~/reports/compliance/default.aspx?id=" + Container.NodeId;

        string selectedRegionString = "";

        foreach (ListItem item in RegionsChecklist.Items)
        {
            if (item.Selected)
            {
                selectedRegionString = selectedRegionString + item.Value + ",";
            }
        }

        url += "&region=" + selectedRegionString.TrimEnd(','); 
        Response.Redirect(ResolveUrl(url));
    }

但我不知道我需要改变什么，如果我找对地方？有人能给我提点建议吗？

Answer 1

我使用了在上面的答案中提供给我的内容，并设法将下面的代码片段组合在一起，这是一个不错的方法。

this.Title =“汇总”+ Container.Name；

        if (SelectedRegions.Count > 1)
        {
            RegionId = SelectedRegions.First();
            this.Title = "Summary for " + Container.Name + " (Multiple Regions)";
        }
        else if (SelectedRegions.Count > 0)
        {
            RegionId = SelectedRegions.First();
            this.Title += string.Format(" ({0})", NodeBasic.GetNodeBasic(RegionId).Name);
        }
        else
        {
            RegionId = 0;
            this.Title = "Summary for " + Container.Name;
        }

在客户端处理这个问题是个好主意。

试着跟随

<script type="text/javascript">
$(document).ready(function(){
    $('input[type="checkbox"]').click(function(){
        if($(this).prop("checked") == true){
            $(document).attr("title", $(this).next().text());
        }
        else if($(this).prop("checked") == false){
        }
    });
});

​

这将将页面的标题更改为选中的复选框的"Text“属性。

确保您没有设置AutoPostBack="True“。

更新-用于服务器端

要在服务器端处理它，请设置AutoPostBack = "true“

然后在后面的代码中尝试如下

 string sTitle = "";

            if (CheckBox1.Checked)
            {
                sTitle += CheckBox1.Text + " ";
            }
            if (CheckBox2.Checked)
            {
                sTitle += CheckBox2.Text + " ";
            }

            this.Title = sTitle;
