将数据添加到.Ajax数据+额外数据 [英] Add Data to .Ajax data + extra data

问题描述

您好，我希望能够向在Ajax上提交的数据中添加其他数据:

Hello I want to be able to add additional data to my data being submitted on Ajax:

<script type="text/javascript">
$(document).ready(function() {
    //http://www.datatables.net
$('#dataTable').dataTable({
        "sPaginationType": "full_numbers",
        "bJQueryUI": false,
        "bProcessing": true,
        "bServerSide": true,
        "sAjaxSource": "/Project/GetDataTables2",
        "aoColumns": [
            { "bSortable": true },
            { "bSortable": true },
            { "bSortable": true },
            { "bSortable": true }
        ],
        "fnServerData": function(url, data, callback) {
            $.ajax({
                "url": url,
                "data": data, //I want to add additional data from here like the QueryString DPID
                "success": callback,
                "contentType": "application/x-www-form-urlencoded; charset=utf-8",
                "dataType": "json",
                "type": "POST",
                "cache": false,
                "error": function() {
                    alert("DataTables warning: JSON data from server failed to load or be parsed. " +
                    "This is most likely to be caused by a JSON formatting error.");
                }
            });
        }
    });
});                    
</script>

我尝试做:

data: data + "&moredata=" + morevalue 

但是我收到脚本错误，它不会将其发送到我的URL ...请帮助！

However I get a script error and it won't send it to my URL... Please help!

我现在正在传递它，就像这个DPID碰巧，但dt却没有:

I am now passing it like this DPID comes across fine but dt does not:

<script type="text/javascript">
$(document).ready(function() {
    //http://www.datatables.net
    $('#dataTable').dataTable({
        "sPaginationType": "full_numbers",
        "bJQueryUI": false,
        "bProcessing": true,
        "bServerSide": true,
        "sAjaxSource": "/Project/GetDataTables2",
        "aoColumns": [
            { "bSortable": true },
            { "bSortable": true },
            { "bSortable": true },
            { "bSortable": true }
        ],
        "fnServerData": function(url, data, callback) {
            $.ajax({
                "url": url,
                "data": { DPID: "1", dt: data }, //I want to add additional data from here like the QueryString DPID
                "success": callback,
                "contentType": "application/x-www-form-urlencoded; charset=utf-8",
                "dataType": "json",
                "type": "POST",
                "cache": false,
                "error": function() {
                    alert("DataTables warning: JSON data from server failed to load or be parsed. " +
                    "This is most likely to be caused by a JSON formatting error.");
                }
            });
        }
    });
});                    
</script>

推荐答案

如果要向ajax请求中添加一些其他数据，请使用以下方法:

if you want to add some additional data to the ajax request, use this:

"fnServerParams": function ( aoData ) {
                aoData.push( { "key": "value" } );
 }
