如何在JavaScript中获取repeater项的计数

如何在JavaScript中获取repeater项的计数

---

您可以在服务器端计算datatable的datasourcedatatable.Rows.count项的数量，或者如果是list.count。。。并将其保存在javascript变量中

例如，如果您的数据源是一个列表

int count = yourList.Count;
repetear.DataSource = yourList;
...

ClientScript.RegisterClientScriptBlock(this.GetType(), "countRepeaterItems",
                    string.Format("var countRepetear = {0};", count ));

现在，您有了一个带有项目数的变量countrepetar

int count = yourList.Count;
repetear.DataSource = yourList;
...

ClientScript.RegisterClientScriptBlock(this.GetType(), "countRepeaterItems",
                    string.Format("var countRepetear = {0};", count ));
