畅言评论代码和discuz外部调用代码冲突，手机端不显示评论，将discuz的调用代码去掉之后，畅言评论就正常了，求解冲突原因及解决办法，代码如下：

畅言评论代码：

<div id="SOHUCS" sid="$article[aid]" ></div>
<script type="text/javascript">
(function() {
    var appid = 'cytTbjla6';
    var conf = 'prod_3aeea31d79efd447e8ef61a7ff76eb40';
    var width = window.innerWidth || document.documentElement.clientWidth;
    if (width < 960) {
        window.document.write('<script id="changyan_mobile_js" charset="utf-8" type="text/javascript" src="https://changyan.sohu.com/upload/mobile/wap-js/changyan_mobile.js?client_id=' + appid + '&conf=' + conf + '"><\/script>');
    } else {
        var loadJs = function(d, a) {
            var c = document.getElementsByTagName("head")[0] || document.head || document.documentElement;
            var b = document.createElement("script");
            b.setAttribute("type", "text/javascript");
            b.setAttribute("charset", "UTF-8");
            b.setAttribute("src", d);
            if (typeof a === "function") {
                if (window.attachEvent) {
                    b.onreadystatechange = function() {
                        var e = b.readyState;
                        if (e === "loaded" || e === "complete") {
                            b.onreadystatechange = null;
                            a()
                        }
                    }
                } else {
                    b.onload = a
                }
            }
            c.appendChild(b)
        };
        loadJs("https://changyan.sohu.com/upload/changyan.js",
        function() {
            window.changyan.api.config({
                appid: appid,
                conf: conf
            })
        });
    }
})();
</script>

Discuz外部调用代码：

<script type="text/javascript" src="http://bbs.sddp.net/api.php?mod=js&bid=495"></script>

开始以为是document.write的原因，但是把畅言评论代码改成jquery写入，能将js写入到页面，但评论的html依然没有出来：

if (width < 960) {
var changyanjs = document.createElement('script');
changyanjs.type = 'text/jacascript';changyanjs.id = 'changyan_mobile_js';changyanjs.src = 'https://changyan.sohu.com/upload/mobile/wap-js/changyan_mobile.js?client_id=cytTbjla6&conf=prod_3aeea31d79efd447e8ef61a7ff76eb40';
jQuery('#SOHUCS').append(changyanjs)
}

请问到底是哪里冲突呢？求解
