追加不上？ 可以定义一个变量最后追加：

<span class="hljs-keyword">var</span> str = '';
<span class="hljs-keyword">for</span>(<span class="hljs-keyword">var</span> i = 0; i <span class="hljs-keyword">var</span> funId=jsonArray[i].funId;
        <span class="hljs-keyword">var</span> funName = jsonArray[i].funName;
        <span class="hljs-keyword">var</span> url = jsonArray[i].url;
str += '<<span class="hljs-keyword">li</span> <span class="hljs-keyword">class</span>=<span class="hljs-string">"subnav-li"</span> href=<span class="hljs-string">"'+ url +'"</span> data-id=<span class="hljs-string">"'+ funId +'"</span>><span class="hljs-string">"javascript:;"</span> <span class="hljs-keyword">class</span>=<span class="hljs-string">"ue-clear"</span>><span class="hljs-keyword">class</span>=<span class="hljs-string">"subnav-icon"</span>><span class="hljs-keyword">class</span>=<span class="hljs-string">"subnav-text"</span>>'+ funName +'<span class="hljs-keyword">li</span>>';
                    }
    $(<span class="hljs-string">".subnav:first"</span>).<span class="hljs-keyword">append</span>(str);
