一、项目介绍

运用angular+angular-cli+angular-router+ngrx/store+rxjs+webpack+node+wcpop等技术实现开发的仿微信angular版聊天室angular-chatroom实例项目,实现了下拉刷新、聊天消息右键菜单、发送消息、表情(动图),图片、视频预览,红包打赏等功能。

二、技术实现

  • mvvm框架:angular8.0 / @angular/cli
  • 状态管理:@ngrx/store / rxjs
  • 地址路由:@angular/router
  • 弹窗组件:wcpop
  • 打包工具:webpack 2.0
  • 环境配置:node.js + cnpm
  • 图片预览:previewimage
  • 轮播滑动:swiper

    private auth: any

◆ 编辑器核心消息处理

function surrounds() {

        var sel = window.getselection();
        var anchornode = sel.anchornode;
        if (!anchornode) return;

            var range = sel.getrangeat(0);
            var p = document.createelement("p");
            range.surroundcontents(p);
            range.selectnodecontents(p);
            range.insertnode(document.createelement("br")); //chrome
            sel.collapse(p, 0);

            (function clearbr() {
                var elems = [].slice.call($(".j__wceditor")[0].children);
                for (var i = 0, len = elems.length; i < len; i++) {
                    var el = elems[i];
                    if (el.tagname.tolowercase() == "br") {
                        $(".j__wceditor")[0].removechild(el);
                    }
                }
                elems.length = 0;
            })();
        }
    }, 10);
}

// 定义最后光标位置
var _lastrange = null, _sel = window.getselection && window.getselection();
var _rng = {
    getrange: function () {
        if (_sel && _sel.rangecount > 0) {
            return _sel.getrangeat(0);
        }
    },
    addrange: function () {

            _sel.removeallranges();
            _sel.addrange(_lastrange);
        }
    }
}

// 消息处理
function isempty() {
    // var html = $editor.html();
    var html = $(".j__wceditor").html();
    html = html.replace(/<br[\s\/]{0,2}>/ig, "\r\n");
    html = html.replace(/<[^img].*?>/ig, "");
    html = html.replace(/&nbsp;/ig, "");
    return html.replace(/\r\n|\n|\r/, "").replace(/(?:^[ \t\n\r]+)|(?:[ \t\n\r]+$)/g, "") == "";
}
