bootstrap 重写JS的alert、comfirm函数

时间:2022-10-26 05:10:17

原理是使用bootstrap的Modal插件实现。

一、在前端模板合适的地方,加入Modal展现div元素。

<!-- system modal start -->
<div id="ycf-alert" class="modal">
    <div class="modal-dialog modal-sm">
        <div class="modal-content">
            <div class="modal-header">
                <button type="button" class="close" data-dismiss="modal"><span aria-hidden="true">×</span><span class="sr-only">Close</span></button>
                <h5 class="modal-title"><i class="fa fa-exclamation-circle"></i> [Title]</h5>
            </div>
            <div class="modal-body small">
                <p>[Message]</p>
            </div>
            <div class="modal-footer" >
                <button type="button" class="btn btn-primary ok" data-dismiss="modal">[BtnOk]</button>
                <button type="button" class="btn btn-default cancel" data-dismiss="modal">[BtnCancel]</button>
            </div>
        </div>
    </div>
</div>
<!-- system modal end -->

二、在前端模板的公共模块,找合适的地方引入bootstrap

<link rel="stylesheet" href="__TPL__/css/photoswipe.css">
 
<script type="text/javascript" src="__PUBLIC__/js/jquery.min.js" ></script>
<script src="__PUBLIC__/bootstrap/js/bootstrap.min.js"></script>

三、在JS的comon层,加入重写语句。

//封装alert、confirm
    window.Modal = function () {
        var reg = new RegExp("\\[([^\\[\\]]*?)\\]", 'igm');
        var alr = $("#ycf-alert");
        var ahtml = alr.html();
 
 
        var _alert = function (options) {
            alr.html(ahtml);    // 复原
            alr.find('.ok').removeClass('btn-success').addClass('btn-primary');
            alr.find('.cancel').hide();
            _dialog(options);
 
            return {
                on: function (callback) {
                    if (callback && callback instanceof Function) {
                        alr.find('.ok').click(function () { callback(true) });
                    }
                }
            };
        };
 
        var _confirm = function (options) {
            alr.html(ahtml); // 复原
            alr.find('.ok').removeClass('btn-primary').addClass('btn-success');
            alr.find('.cancel').show();
            _dialog(options);
 
            return {
                on: function (callback) {
                    if (callback && callback instanceof Function) {
                        alr.find('.ok').click(function () { callback(true) });
                        alr.find('.cancel').click(function () { callback(false) });
                    }
                }
            };
        };
 
        var _dialog = function (options) {
            var ops = {
                msg: "提示内容",
                title: "操作提示",
                btnok: "确定",
                btncl: "取消"
            };
 
            $.extend(ops, options);
 
            //console.log(alr);
 
            var html = alr.html().replace(reg, function (node, key) {
                return {
                    Title: ops.title,
                    Message: ops.msg,
                    BtnOk: ops.btnok,
                    BtnCancel: ops.btncl
                }[key];
            });
 
            alr.html(html);
            alr.modal({
                width: 500,
                backdrop: 'static'
            });
        }
 
        return {
            alert: _alert,
            confirm: _confirm
        }
 
    }();

四、在需要的地方调用。

Modal.confirm(
    {
       msg: "商品已成功加入购物车\n是否去购物车查看?"
    })
    .on( function (e) {
       if(e)
            location.href = cart_url;
    });
