网页中同时导入2种js库,并且加上了 var jquery = $.noConflict(true); 但是页面中报错了

 <div style="float: right; padding-right: 12px;" class="headerseach">

<script>
    (function(scope) {

                document.getElementById('searchbar_3949').submit();

    })($('searchbar_3949'));




        jquery("#search_keywords").autocomplete({

</script></div>

chrome控制台报错了： Uncaught TypeError: undefined is not a function 说的是 ($('searchbar_3949')); 这个闭包调用函数
