jquery autocomplete renderItem

Question

我有以下代码.它不会生成js错误.无法获取自动完成功能以显示任何结果:

$(function() {
    $.ajax({
    url: "data.xml",
    dataType: "xml",
    cache: false,
    success: function (xmlResponse) {
        var data_results = $("Entry", xmlResponse).map(function () {
            return {
                var1: $.trim($("Partno", this).text()),
                var2: $.trim($("Description", this).text()),
                var3: $.trim($("SapCode", this).text()),
                var4: $("Title", this).text(),
                var5: $.trim($("File", this).text()),
                var6: $.trim($("ItemID", this).text())
            };
        }).get();

        $("#searchresults").autocomplete({
            source: data_results,
            minLength: 3,
            select: function (event, ui) {
                ...
            }
        }).data( "autocomplete" )._renderItem = function( ul, item ) {
                return $( "<li></li>" ).data("item.autocomplete", item)
                    .append( "<a>" + item.var1 + "<br>" + item.var2 + "</a>")
                    .appendTo( ul );
        };

    }
});

我可能会缺少什么想法？提前致谢.

现在好像.data('autocomplete')是现在.data('ui-autocomplete').

默认情况下,自动填充要求源数组包含具有label属性,value属性或两者的对象.

考虑到这一点,您有两种选择:

1. 从AJAX调用处理数组时,向源对象添加标签或值属性:

   var data_results = $("Entry", xmlResponse).map(function () {
       return {
           var1: $.trim($("Partno", this).text()),
           var2: $.trim($("Description", this).text()),
           var3: $.trim($("SapCode", this).text()),
           var4: $("Title", this).text(),
           var5: $.trim($("File", this).text()),
           var6: $.trim($("ItemID", this).text()),
           value: $.trim($("Description", this).text())
       };
   }).get();
   

   该value分配将用于对focus,select和搜索上.

2. 更改source功能以执行自定义过滤逻辑:

   $("#searchresults").autocomplete({
       source: function (request, response) {
           var matcher = new RegExp($.ui.autocomplete.escapeRegex(request.term), "i");
   
           response($.grep(data, function (value) {
               return matcher.test(value.var1) || 
                      matcher.test(value.var2);
               /* etc., continue with whatever parts of the object you want */
           }));
       },
       minLength: 3,
       select: function (event, ui) {
           event.preventDefault();
           this.value = ui.var1 + ui.var2;
       },
       focus: function (event, ui) {
           event.preventDefault();
           this.value = ui.var1 + ui.var2;
       }
   }).data( "autocomplete" )._renderItem = function( ul, item ) {
           return $( "<li></li>" ).data("item.autocomplete", item)
               .append( "<a>" + item.var1 + "<br>" + item.var2 + "</a>")
               .appendTo( ul );
   };
   

   请注意,使用此策略,您必须实现自定义select和focus逻辑.
