Dynamics CRM JS 隐藏子网格“＋”号（不推荐，随笔记录）

调用示例代码：

 hideAddButton(window, "tab_approval_process,nextcustomer,billTo,account_attachment");

function hideAddButton(w, subgrids) {
    ///<summary>隐藏子网格加号按钮</summary>
    /// <param name="w">window对象</param>
    /// <param name="subgrids">子网格名称，多个英文逗号隔开</param>
  var subgrid = subgrids.split(',');
    for (var i = 0; i < subgrid.length; i++) {
        var _id = subgrid[i] + "_contextualButtonsContainer";      var _button = w.document.getElementById(_id);
        if ((_button == null || _button == undefined) && window.parent != null && window.parent != undefined) {
            _button = w.parent.window.document.getElementById(_id);
        }
        if (_button != undefined && _button != null) {
            _button.style.display = "none";
        }
    }
}

function hideAddButton(w, subgrids) {    ///<summary>隐藏子网格加号按钮</summary>    /// <param name="w">window对象</param>    /// <param name="subgrids">子网格名称，多个英文逗号隔开</param>    console.log("w=" + w);    console.log("subgrids=" + subgrids);
    var subgrid = subgrids.split(',');    for (var i = 0; i < subgrid.length; i++) {        var _id = subgrid[i] + "_contextualButtonsContainer";        console.log("ID=" + subgrid[i] + "，i=" + i);        var _button = w.document.getElementById(_id);
        if ((_button == null || _button == undefined) && window.parent != null && window.parent != undefined) {            _button = w.parent.window.document.getElementById(_id);        }        if (_button != undefined && _button != null) {            _button.style.display = "none";            console.log("ID=" + _id + "，Display=" + _button.style.display);        }    }
}
