引导自动完成不加载地图

问题描述

我有一个地图，是一个JSON的结果。我需要分配它自动完成。但是好像我必须做一个肮脏的工作。有没有清洁的方式做到这一点？

在code这是很肮脏的一部分：

  $（＃autocomplete1）.autocomplete（{        来源：函数（请求，响应）{
            VAR重= $ .ui.autocomplete.escapeRegex（request.term）;
            VAR匹配=新的RegExp（N *+重+N *，我）;
            VAR arrayKey = $ .MAP（v1.data，功能（的ItemKey，itemValue）{
                返回的ItemKey
            }）;
            VAR arrayValue = $ .MAP（v1.data，功能（的ItemKey，itemValue）{
                返回itemValue
            }）;
            VAR键= $ .grep（arrayKey，功能（项指数）{
                返回matcher.test（项目）;
            }）;
            VAR值= $ .grep（arrayValue，功能（项指数）{
                返回matcher.test（项目）;
            }）;            变种S ={;
            对于（VAR I = 0; I＆LT; key.length;我++）{
                如果（ⅰ＆下; value.length）{
                    S + =\\+值[I] +\\：\\+键[I] +\\，;
                }
            }
            S = s.substring（0，s.length-1）;
            S + =};            VAR的JSONObject = jQuery.parseJSON（S）;            响应（$。图（JSONObject的，功能（的ItemKey，itemValue）{
                返回{
                    标签：的ItemKey，
                    值：itemValue
                };
            }））;
        }    }）;
 

解决方案

简单地做到这一点：

  VAR I = 0;
    VAR代表codesMap = v1.data;
    VAR代表codesSource =新的Array（）;
    $。每个市（REP codesMap，功能（键，值）{
        代表codesSource [我++] = {标签：值，值：关键};
    }）;    $（＃autocomplete1）.autocomplete（{
        来源：代表codesSource
    }）;
 

在这里更新了code：

I have a map which is a JSON result. I need to assign it to autocomplete. But it seems like I have to do a dirty job. Is there any cleaner way to do that?

part of the code which is very dirty:

$( "#autocomplete1" ).autocomplete({

        source: function(request, response) {
            var re = $.ui.autocomplete.escapeRegex(request.term);
            var matcher = new RegExp( "n*" + re + "n*", "i");
            var arrayKey = $.map(v1.data, function (itemKey, itemValue) {
                return itemKey
            });
            var arrayValue = $.map(v1.data, function (itemKey, itemValue) {
                return itemValue
            });
            var key = $.grep( arrayKey, function(item,index){
                return matcher.test(item);
            });
            var value = $.grep( arrayValue, function(item,index){
                return matcher.test(item);
            });

            var s = "{ ";
            for (var i =0; i< key.length; i++) {
                if (i < value.length) {
                    s+= "\"" + value[i] + "\":\"" + key[i] + "\",";
                }
            }
            s = s.substring(0, s.length-1);
            s += "}";

            var jsonObject = jQuery.parseJSON(s);

            response($.map(jsonObject, function (itemKey, itemValue) {
                return {
                    label: itemKey,
                    value: itemValue
                };
            }));
        }



    });

解决方案

simply do this:

    var i = 0;
    var repCodesMap = v1.data;
    var repCodesSource = new Array();
    $.each(repCodesMap, function(key, value) {
        repCodesSource[i++] = { label : value, value : key };
    });

    $( "#autocomplete1" ).autocomplete({
        source : repCodesSource
    });
