jQuery启用禁用按钮防止重复提交、layer.confirm确定按钮锁定防止重复触发事件

<a class="btn btn-warning" id="releaseBtn" onclick="ShipPlanManager.release()">
 <i class="fa fa-pencil">i> 计划下发
a>

/**
 * 计划下发
 */
ShipPlanManager.release = function () {
 if (this.check()) {
     //禁用按钮
     $("#releaseBtn").attr("disabled", true);
     $("#releaseBtn").removeAttr("onclick");
     var data = $('#' + this.id).bootstrapTable('getSelections');
     var ids = "";
     for (var i = 0; i < data.length; i++) {
         ids = ids + data[i].id + ",";
     }
     ids = ids.substring(0, ids.length - 1);
     var lock = false;//默认未锁定
     parent.layer.confirm('是否确认下发？', {
         btn: ['确定', '取消'],
         shade: false, //不显示遮罩
     }, function () {
         if (!lock) {
             lock = true;
             var ajax = new $ax(Feng.ctxPath + "/shipplanmanager/release", function (data) {

                 ShipPlanManager.table.refresh();
                 //启用按钮
                 $("#releaseBtn").removeAttr("disabled");
