web版仿微信聊天界面|h5仿微信电脑端案例开发

前几天开发了一款手机端h5仿微信聊天，人唯有不停学习才能进步，这段时间倒腾着整理了下之前项目，又重新在原先的那版基础上开发了一款仿微信聊天电脑端web版本，聊天页面又重新优化了多图预览、视频播放，右键菜单menu，聊天底部编辑器模块重新优化源码，弹窗则是继续使用之前自己开发的wcPop.js，具体看项目效果图吧！

效果图：

// ...表情、选择区切换
$(".wc__editor-panel").on("click", ".btn", function(){
    var that = $(this);
    $(".wc__choose-panel").show();
    if (that.hasClass("btn-emotion")) {
        $(".wc__choose-panel .wrap-emotion").show();
        $(".wc__choose-panel .wrap-choose").hide();
        // 初始化swiper表情
        !emotionSwiper && $("#J__emotionFootTab ul li.cur").trigger("click");
    } else if (that.hasClass("btn-choose")) {
        $(".wc__choose-panel .wrap-emotion").hide();
        $(".wc__choose-panel .wrap-choose").show();
    }
    wchat_ToBottom();
});

// ...处理编辑器信息
var $editor = $(".J__wcEditor"), _editor = $editor[0];
function surrounds(){
    setTimeout(function () { //chrome
        var sel = window.getSelection();
        var anchorNode = sel.anchorNode;
        if (!anchorNode) return;
        if (sel.anchorNode === _editor ||
            (sel.anchorNode.nodeType === 3 && sel.anchorNode.parentNode === _editor)) {
            
            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(_editor.children);
                for (var i = 0, len = elems.length; i < len; i++) {
                    var el = elems[i];
                    if (el.tagName.toLowerCase() == "br") {
                        _editor.removeChild(el);
                    }
                }
                elems.length = 0;
            })();
        }
    }, 10);
}
// 格式化编辑器包含标签
_editor.addEventListener("click", function () {
    //$(".wc__choose-panel").hide();
}, true);
_editor.addEventListener("focus", function(){
    surrounds();
}, true);
_editor.addEventListener("input", function(){
    surrounds();
}, false);
// 点击表情
$("#J__swiperEmotion").on("click", ".face-list span img", function(){
    var that = $(this), range;

    if(that.hasClass("face")){ //小表情
        var img = that[0].cloneNode(true);
        _editor.focus();
        _editor.blur(); //输入表情时禁止输入法

        setTimeout(function(){
            if(document.selection && document.selection.createRange){
                document.selection.createRange().pasteHTML(img);
            }else if(window.getSelection && window.getSelection().getRangeAt){
                range = window.getSelection().getRangeAt(0);
                range.insertNode(img);
                range.collapse(false);

                var sel = window.getSelection();
                sel.removeAllRanges();
                sel.addRange(range);
            }
        }, 10);
    }else if(that.hasClass("del")){ //删除
        _editor.focus();
        _editor.blur(); //输入表情时禁止输入法

        setTimeout(function(){
            range = window.getSelection().getRangeAt(0);
            range.collapse(false);

            var sel = window.getSelection();
            sel.removeAllRanges();
            sel.addRange(range);
            document.execCommand("delete");
        }, 10);
    } else if(that.hasClass("lg-face")){ //大表情
        var _img = that.parent().html();
