jQuery无法在ASP.Net母版页中工作

标签: jquery asp.net master-pages

当我在普通的ASP.Net页面中使用jQuery DataTable时,它工作正常。但是,当我在母版页中使用相同的代码时,它会给我一个错误:

  

未捕获TypeError:$(...)。prepend(...)。dataTableExt不是函数

我正在用作品写两个代码:

工作代码:

.aspx页码

 RequestQueue queue = Volley.newRequestQueue(LoginActivity.this);
    final ProgressDialog pDialog = new ProgressDialog(LoginActivity.this);
pDialog.setMessage("Logging In...");
    pDialog.show();

    JsonObjectRequest jsonObjReq = new JsonObjectRequest(Request.Method.POST, Constants.URL_Login, Jsonobj,
            new Response.Listener<JSONObject>() {
                @Override
                public void onResponse(JSONObject response) {
                    // mPostCommentResponse.requestCompleted();
                    Log.e(TAG, "Service--o/p-" + response);
                    pDialog.dismiss();
                }
            }, new Response.ErrorListener() {
        @Override
        public void onErrorResponse(VolleyError error) {
            // mPostCommentResponse.requestEndedWithError(error);
            Log.e("TAG", "Service--i/p-" + error);
            pDialog.dismiss();

        }
    });
    jsonObjReq.setRetryPolicy(new DefaultRetryPolicy(
            60000,
            DefaultRetryPolicy.DEFAULT_MAX_RETRIES,
            DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));


    queue.add(jsonObjReq);

1 个答案:

答案 0 :(得分:1)

调用类似的东西

$(function () {
    $("table[id$='DataGridView']").prepend( $("<thead></thead>").append( $(this).find("tr:first") ) ).dataTable();
});

还要确保所有引用的js文件都存在。这意味着您在控制台中没有收到404错误。

其次,我建议将列呈现信息保存在aspx标记中,而不是将其保存在代码中。如下所示:

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false" OnRowDataBound="OnRowDataBound">
    <Columns>
        <asp:BoundField DataField="Id" HeaderText="Customer Id" ItemStyle-Width="90" />
        <asp:BoundField DataField="" HeaderText="Name" ItemStyle-Width="120" />
        <asp:BoundField DataField="Country" HeaderText="Country" ItemStyle-Width="100" />
    </Columns>
</asp:GridView>

不要使用prerender事件,所有这些都可以通过标记来完成。所以尽可能多地使用它。在代码中,只需将数据集绑定到网格视图并调用databind事件。

GridView1.DataSource = ds; // here assume ds is a dataset
GridView1.DataBind();
