Javascript 加载前两个图表时加载图表

我有两个通过按钮加载的图表，我想启动第三个（之前2个之间的%），当两个都加载时，是否有人能提供一种方法来添加一个控件，如果两个都加载了，那么可以加载第三个图表

我希望澄清

谢谢

//first function (starts with a button)
function loadGrafico(array_Label, array_Risultati) {
    var grafico = document.getElementById("query1");
    var query1 = new Chart(grafico, {
        type: 'bar',
        data: {
            labels: array_Label,
            datasets: [
                {
                    backgroundColor: [

                        ],
                    borderWidth: 1,
                    data: array_Risultati,
                    }
                ]
        }
    });
}
//second function (starts with a button too)
function loadChart(array_Label, array_N_valutazioni) {
    var crt = document.getElementById("query2");
    var query = new Chart(crt, {
        type: 'bar',
        data: {
            labels: array_Label,
            datasets: [
                {
                    backgroundColor: [

                        ],
                    borderWidth: 1,
                    data: array_N_valutazioni,
                    }
                ]
        }
    });
}
//that's the function have to be loaded when the 2 before are loaded
function loadPercentuale(array_Label, array_Percentuale) {
    var grafo = document.getElementById("percentuale");
    var percentuale = new Chart(grafo, {
        type: 'bar',
        data: {
            labels: array_Label,
            datasets: [
                {
                    backgroundColor: [

                        ],
                    borderWidth: 1,
                    data: array_Percentuale
                    }
                ]
        }
    });
}

你为什么不试试标志变量呢？我希望这不是一个更好的解决方案，但它会对您有所帮助。在包含布尔值的两个函数中放置两个标志变量。然后调用第三个函数如果两个变量都返回true，则第三个函数将加载，并且图表也将自动加载

在您的注释和详细信息之后，我认为您正在寻找类似以下内容：

 // tmpArray, starting values are just to let you see what I'll store in there.
var tmpArray=[['array_Risultati'],['array_N_valutazioni']];
var tmpArrayLabel=[];

// function to calculate percentage between array values
function getPercent(){
    var return_array = [];
    for(var i=0; i < tmpArray[0].length; i++)
        return_array[i] = parseInt(tmpArray[0][i]*tmpArray[1][i]/100); 
    return return_array;
}

//first function (starts with a button)
function loadGrafico(array_Label, array_Risultati) {
    tmpArray[0]=array_Risultati;
    var grafico = document.getElementById("query1");
    var query1 = new Chart(grafico, {
        type: 'bar',
        data: {
            labels: array_Label,
            datasets: [{
                    backgroundColor: [],
                    borderWidth: 1,
                    data: array_Risultati,
                    }]
        }
    });
    // Verify if loadChart for this array_Label has been called to execute loadPercentuale
    if (tmpArrayLabel==array_Label) loadPercentuale();
    tmpArrayLabel=array_Label;
}

//second function (starts with a button too)
function loadChart(array_Label, array_N_valutazioni) {
    tmpArray[1]=array_N_valutazioni;
    var crt = document.getElementById("query2");
    var query = new Chart(crt, {
        type: 'bar',
        data: {
            labels: array_Label,
            datasets: [{
                    backgroundColor: [],
                    borderWidth: 1,
                    data: array_N_valutazioni,
                    }]
        }
    });
    // Verify if loadGrafico for this array_Label has been called to execute loadPercentuale
    if (tmpArrayLabel==array_Label) loadPercentuale();
    tmpArrayLabel=array_Label;
}

// That's the function have to be loaded when the 2 before are loaded
function loadPercentuale() {
    var array_Percentuale=getPercent();
    var grafo = document.getElementById("percentuale");
    var percentuale = new Chart(grafo, {
        type: 'bar',
        data: {
            labels: tmpArrayLabel,
            datasets: [{
                    backgroundColor: [],
                    borderWidth: 1,
                    data: array_Percentuale,
                    }]
        }
    });
}

在loadPercentuale函数中需要传递哪些数据？voglio passarli array_Label在ASCSASSAOK中的顺序为e la percentuale tra array_Risultati e array_N_valutazioni，但在第二个函数中只有array_N_valutazioni，因此我必须假设您只能在第二个函数之后执行第三个函数？这是真的吗？只有在第一个和第二个都加载之后，你才能检查我的答案吗？我通过0只是为了测试，但它应该可以工作。你能给我一个例子吗？函数functionOne（）{//在这个函数的结果出来后，放置两个标志变量并给它们赋值。boolOne=true；boolTwo=true；}//现在调用两个函数，比如if（boolOne）{//调用function2}现在，第一个和第二个图表没有显示结果，第三个图表也没有，有GET调用，但没有图表startsBuongiorno！我想我需要看更多的代码来理解你在做什么。。。我是说ajax调用在哪里？你能提供一把小提琴吗？不管怎样，现在我想那一定是逗号的错误。。我已经编辑了答案。试试看，没有办法……但是对于我用另一种方法做的控制，所以现在我只需要计算array_Risultati和array_N_valutazioni的百分比，你能给我建议一种计算方法吗？谢谢，请使用函数getPercent，我已经完成了。但正如我所说，谷歌：Vixed

// Caching #percentuale element
var $percentuale=$('#percentuale');
