Question

我是html和java-script的新手。对于我的代码我不断得到我的功能没有定义，我无法弄清楚为什么。香港专业教育学院尝试将脚本移动到头标签和通话后。香港专业教育学院尝试更改功能的名称，以确保它还没有被使用。我想我错过了一些小而愚蠢的东西。任何帮助将不胜感激

以下代码更正了您的语法错误，现在正在调用函数（您可以根据需要查看＆＃34; hello＆＃34;警告）。

＆＃13;

    var d = [0,0,0,0,0];

    function aaa()
    {   alert( "hello" );
        for (var i = 0; i<5; i++){
        var da = Math.floor(Math.random()*6) +1;
        var di = document.getElementById("d" + i);
        di.src = "pix/dice" + d + ".gif";
        }
    }

    function newGame(){
    }

    function click1()   {
        var total = 0;
        for (var i = 0; i <5; i++){
        if (d[i] == 1 ) total +=1;}
        var loco = document.getElementById("s1");
        loco.innerHTML = total;

        }

错误是您忘记在pandas之后添加df=pd.concat([df1,df2],keys=['old','new']) df=df.drop_duplicates(['node1','node2'],keep=False).loc['new'] df=pd.crosstab(df.node1,df.node2).reindex(index=[1,2,3,4,5],columns=[1,2,3,4,5]).fillna(0) pd.DataFrame(df.values.T+df.values,index=[1,2,3,4,5],columns=[1,2,3,4,5],dtype=int) Out[894]: 1 2 3 4 5 1 0 0 0 1 0 2 0 0 0 0 0 3 0 0 0 0 1 4 1 0 0 0 0 5 0 0 1 0 0
