你好！
我写了个示示例，方法可能会和你的不同。方法是在服务记录未被禁用的 checkBox。全选时只对这部分 checkBox 操作。
<%@ Page Language="C#" AutoEventWireup="true" %>
<%@ Import Namespace="System.Data" %>
<script runat="server">
protected void Page_Load(object sender, EventArgs e)
{
DataTable dt = new DataTable();
dt.Columns.Add("Id", typeof(int));
dt.Columns.Add("Name", typeof(string));
dt.PrimaryKey = new DataColumn[] { dt.Columns["Id"] };
dt.Rows.Add(new object[] { 1, "Sam"});
dt.Rows.Add(new object[] { 2, "XXY" });
dt.Rows.Add(new object[] { 3, "John" });
dt.Rows.Add(new object[] { 4, "Meliy" });
dt.Rows.Add(new object[] { 5, "Tom" });
this.GridView1.DataSource = dt;
this.GridView1.DataBind();
}
string javascriptArray = string.Empty;
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.Header)
{
CheckBox checkBox = e.Row.FindControl("checkBox1") as CheckBox;
checkBox.Attributes["onclick"] = "SetAllItemCheckedState(this);";
}
if (e.Row.RowType == DataControlRowType.DataRow)
{
CheckBox checkBox = e.Row.FindControl("checkBox1") as CheckBox;
if (checkBox == null)
return;
if (e.Row.RowIndex % 2 == 0)
{
// rowIndex 为偶数时禁用 checkBox
checkBox.Enabled = false;
}
else
{
// 将未禁用的 checkbox 控件 id 保存到数组中在 js 中使用。
if (javascriptArray != string.Empty)
javascriptArray += ", ";
javascriptArray += string.Format("'{0}'", checkBox.ClientID);
}
}
}
protected void GridView1_DataBound(object sender, EventArgs e)
{
string fullJavascriptArray = string.Format("var javascriptArray = new Array({0});", javascriptArray);
string demoJavascript = @"
// 全选所有 CheckBox
function SetAllItemCheckedState(e){
var checked = e.checked;
for(var i in javascriptArray)
document.getElementById(javascriptArray[i]).checked = checked;
}";
this.ClientScript.RegisterStartupScript(this.GetType(), "defined", fullJavascriptArray, true);
this.ClientScript.RegisterStartupScript(this.GetType(), "demo", demoJavascript, true);
}
</script>
