使用jQuery和dc.js在d3.js中出错

Question

我是编程新手，我正在尝试实现一个搜索按钮，可以让我过滤数据。
我在我的serv上有一个url / tweets_complet的JSON数据。然后我想得到另一个JSON，它取决于搜索按钮的输入。一旦我有两个JSON，我就编写了一些代码，我认为这些代码并不重要。

这是js代码：

function main(){
    $.getJSON("/tweets_complet", insererDonneesJson);}


function insererDonneesJson(data){
    $('button').on('click', get_data);

    function get_data() {
        var cashtagg=$('#cash').val();
        $.getJSON("/"+cashtagg, filter);

        function filter(data2) {

    //Tweets datas
            var tweets = data;
            var dateFormat = d3.time.format("%Y-%m-%d %H:%M:%S");
            tweets.forEach(function(d) {
                d["cleandate"] = dateFormat.parse(d["cleandate"]);
                d["cleandate"].setSeconds(0);
            });

            //Create a Crossfilter instance
            var ndx = crossfilter(tweets);

            //Define Dimensions
            var cleandateDim = ndx.dimension(function(d) { return d["cleandate"]; });
            var sentimentDim=ndx.dimension(function(d) { return d["sentiment"]; });
            var bnscoreDim=ndx.dimension(function(d) { return d["bnscore"]; });
            var tickerDim=ndx.dimension(function(d) { return d["collection_name"];});
            var newTickerDim = tickerDim.filter(cashtagg);


            //Calculate metrics
            var numTweetsByTicker=newTickerDim.group()
            var numTweetsByDate = cleandateDim.group(); 
            var numTweetsByBnscore = bnscoreDim.group();
            var totalScoreByDate = cleandateDim.group().reduceSum(function(d) {
                return d["sentiment"]*10/(numTweetsByDate.size());})

            var all = ndx.groupAll();
            var numTweetsBySentiment = sentimentDim.group();



            //Define values (to be used in charts)
            var minDate = cleandateDim.bottom(1)[0]["cleandate"];
            var maxDate = cleandateDim.top(1)[0]["cleandate"];




    //Datas cashtag


            var datas = data2;
            var dateFormatO = d3.time.format("%Y-%m-%d");
            datas.forEach(function(d) {
                d["Date"] = dateFormatO.parse(d["Date"]);
            });


        // Create a Crossfilter instance
            var ndxO = crossfilter(datas);

        // Define Dimensions
            var dateDimO = ndxO.dimension(function(d) { return d["Date"]; });
            var volumeDimO=ndxO.dimension(function(d) { return d["Volume"]; });
            var scoreDimO=ndxO.dimension(function(d) { return d["Low"]; });



        // Calculate metrics

            var groupeVolumeO = dateDimO.group().reduceSum(function(d) { return d["Volume"]/10000000;}); 
            var groupeScoreO = dateDimO.group().reduceSum(function(d) { return d["Low"];}); 


            var allO = ndxO.groupAll();


        // Define values (to be used in charts)
            var minDateO = dateDimO.bottom(1)[0]["Date"];
            var maxDateO = dateDimO.top(1)[0]["Date"];

            var minVolumeO = (volumeDimO.bottom(1)[0]["Volume"])/10000000;
            var maxVolumeO = (volumeDimO.top(1)[0]["Volume"])/10000000;

            var minScoreO = scoreDimO.bottom(1)[0]["Low"];
            var maxScoreO = scoreDimO.top(1)[0]["Low"];





    //Charts
            var timeChart = dc.barChart("#time-chart");
            var pieChart= dc.pieChart("#pie-chart")
            var numberTweetsND = dc.numberDisplay("#number-tweets-nd");

            var shareChart = dc.lineChart("#share-chart");
            var volumeChart = dc.lineChart("#volume-chart");



            numberTweetsND
                .formatNumber(d3.format("d"))
                .valueAccessor(function(d){return d; })
                .group(all);

            .elasticY(true)
            .xAxisLabel("Day")
            .yAxis().ticks(8);

            .group(numTweetsBySentiment)

当我运行serv时，我可以在输入中输入一个值（例如FB）并且它可以工作。但是，从这里开始，我无法将“现金”值更改为AAPL之类的其他内容，因为我收到了错误 未捕获的TypeError：undefined不是函数
    d3.js：2716

这一行是：
 var n = d3_time_numberRe.exec（string.slice（i，i + 4））;

由于我不熟悉$和按钮，我不知道问题的原因...... 任何帮助将不胜感激：）
