jquery防止点击重复

JS：

$("#addOrganizationSure").unbind('click').bind('click', function () {
    var organNameText = $("#organName").val()
    var id = viewModel5.id;
    var options = $("#selectorg option:selected");
    if (options.text() == '新增一个机构') {
        id = 0;
    }
    if (organNameText == '' || organNameText == "机构名称") {
        alert("请输入机构名称")
    } else {
        $.ajax({
            async: false,
            url: "/user/addOrganization",
            type: "GET",
            data: {
                id: id,
                organName: viewModel5.organName,
                organSite: viewModel5.organSite,
                organIntroduce: viewModel5.organIntroduce
            },
            dataType: "JSON",
            success: function (result) {
                if (result != 0) {
                    $("#addOrganization").modal("hide");
                    window.location.reload();
                } else {
                    alert("失败!")
                }
            }
        })
    }
})

Html<button type="button" class="btn btn-primary" id="addOrganizationSure">确认</button>
