javascript - 使用 jQuery 数据表时当前行没有值

标签 javascript jquery html datatables

我正在使用 jQuery 数据表 在单击按钮时获取当前行值。所以为此我尝试了类似下面的东西

function getDashboardData(STATE) {

    try {

        $.ajax({
            type: "POST",
            url: "Dashboard.aspx/BindMWSiteSurvey",
            data: JSON.stringify({ STATE: STATE }),
            contentType: "application/json; charset=utf-8",
            dataType: "json",
            success: function (data) {

                var datVal = JSON.parse(data.d);

                var details = [];

                for (var i = 0, len = datVal.length; i < len; i++) {

                    

                    var result = datVal[i];                  

                    var buttonColumn = "<b><input type='button' data-toggle='modal' data-target='#myModal' value='Update' id='btnEdit' onclick='return OpenPopUpForUpdate("+this+");'></b>";
                    
                    details.push([result.SAP_ID, result.CANDIDATE_ID, result.STATE, result.SITE_NAME, result.CANDIDATESTATUS, result.CURRENT_STATUS, buttonColumn]);
                }

                $('#grdMWSiteSurvey').DataTable({
                    destroy: true,
                    autoWidth: false,
                    "aaData": details,
                    "aoColumns": [
                        { "sTitle": "Sap ID" },
                        { "sTitle": "Candidate ID" },
                        { "sTitle": "State" },
                        { "sTitle": "Site Name" },
                        { "sTitle": "Candidate Status" },
                        { "sTitle": "Current Status" },
                        { "sTitle": "ACTION" }
                    ],
                    "bDestroy": true
                });
            },
            error: function (data) {
                alert('Something went wrong..!!');
            }
        });
    } catch (e) {
        //exception
    }
}


function OpenPopUpForUpdate(aaa) {    
    var row = aaa.parentNode.parentNode;
    var rowIndex = row.rowIndex - 1;
    
}

                <div class="modal-body">

                    <br />

                    <input type="button" id="btnSave" value="Save" class="panelButton" />
                    &nbsp;
                    <input type="button" id="btnDraft" value="Save as Draft" class="panelButton" />

                </div>
                <div class="modal-footer">
                    <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
                </div>
            </div>

        </div>
    </div>

但是我无法获得点击当前行的值。

而且在控制台中它显示为

Uncaught SyntaxError: Unexpected identifier

我应该怎么做才能得到这些值

最佳答案

请不要这样使用 onClick。在 javascript 中使用事件，或者像 jquery 这样的库。例如，请参见下面的代码:

更新:

Javascript:

/* We need to define data, here is a object that we can use to get mock data for testing and real data  */
var dataProvider = {
  getRealData: function(pState) {
    var vDataset = [];
    $.ajax({
      type: "POST",
      url: "Dashboard.aspx/BindMWSiteSurvey",
      data: JSON.stringify({
        STATE: pState
      }),
      contentType: "application/json; charset=utf-8",
      dataType: "json",
      async: false,
      success: function(data) {
        var vDatVal = JSON.parse(data.d);
        var vButtonColumn = '<button type="button" class="btn btn-primary btn-xs dt-edit" style="margin-right:16px;">Edit</span></button>';
        for (var i = 0, len = vDatVal.length; i < len; i++) {
          var vResult = vDatVal[i];
          vDataset.push({
          "SAP_ID": vResult.SAP_ID,
          "CANDIDATE_ID": vResult.CANDIDATE_ID,
          "STATE": vResult.STATE,

         });
        }

    });
    return vDataset;
