jquery：TypeError：this.source不是函数

2019年8月5日 171次阅读

我试图在我的应用程序中集成
Jquery自动完成功能.所需的js文件包括如下：

<script type="text/javascript" src="${pageContext.request.contextPath}/scripts/jquery-1.8.3.js"></script>
<script type="text/javascript" src="${pageContext.request.contextPath}/scripts/jquery.ui.core.min.js"></script>
<script type="text/javascript" src="${pageContext.request.contextPath}/scripts/jquery.ui.widget.min.js"></script>
<script type="text/javascript" src="${pageContext.request.contextPath}/scripts/jquery.ui.autocomplete.min.js"></script>
<script type="text/javascript" src="${pageContext.request.contextPath}/scripts/jquery-ui.min.js"></script>
<script type="text/javascript" src="${pageContext.request.contextPath}/scripts/script.js"></script>

‘scripts.js’文件是特定于应用程序的文件,包含如下代码：

$(document).ready(function() {
    $('#aisleFrom').autocomplete({
        url: '/StoreMapperApp/MapPickingZone.action?autocomplete=',
        minChars: 0,
        max: 10,
        width: 150,
        scroll: true,
        cacheLength: 0
    }).focus(function() {
        $(this).autocomplete('search', $(this).val())
    });
});

但是,当我尝试输入id为’aisleFrom’的文本字段时,我在jquery-ui.min.js文件中收到如下错误：

TypeError：this.source不是函数
    …完全加载“),this.cancelSearch = 1,this.source！({项：电子},this._response())},…

有人可以建议吗？

最佳答案 尝试将网址更改为源.见
Autocomplete Widget source

  jQuery(document).ready(function() {         
    $("#aisleFrom").autocomplete({
        minLength: 0,
        // substitute `source` for `url`
        source: function(request, response) {
          var term = request.term;
          // get json 
          $.getJSON(/* /path/to/json/ */)
          .then(function success(data) {
            // filter results
            var res = $.grep(data, function(val) {
              return new RegExp($.ui.autocomplete.escapeRegex(term), "gi")
                     .test(val.toLowerCase())
            })
            , key = $.inArray(term.toUpperCase(), res)
            , results = term.length === 1 
                          & key !== -1 
                          ? Array(res[key]) 
                          : res;
            response(results)
          }, function error(jqxhr, textStatus, errorThrown) {
               console.log(textStatus, errorThrown) // log `$.ajax` errors
        })
      }
    }).focus(function() {
          $(this).autocomplete("search", $(this).val())
    });          
  });

jQuery(document).ready(function() {

  $("#tags").autocomplete({
    minLength: 0,
    source: function(request, response) {
      var term = request.term;
      $.getJSON("https://gist.githubusercontent.com/anonymous/86f61fee217838ba6c3c/raw/395a557fa400163f048f30370d782db554913b2b/availableTags.json")
        .then(function success(data) {
          var res = $.grep(data, function(val) {
            return new RegExp($.ui.autocomplete.escapeRegex(term), "gi")
              .test(val.toLowerCase())
          })
          , key = $.inArray(term.toUpperCase(), res)
          , results = term.length === 1 
                        && key !== -1 
                        ? Array(res[key]) 
                        : res;
          response(results)
        }, function error(jqxhr, textStatus, errorThrown) {
             console.log(textStatus, errorThrown) // log `$.ajax` errors
      })
    }
  }).focus(function() {
      $(this).autocomplete("search", $(this).val())
  });
  
});
