我正在做一个井字游戏,在那里我需要创建按钮,然后添加事件到它。一行有三个按钮,下一行有三个按钮,下一行有另外三个按钮。我使用了break标记和\r\n符号,但它仍然不起作用。请帮忙

 <body>
    <div id="displaytable"></div>
    <script src='jquery-3.3.1.js'></script>
     <script>
      var table= [];
       var blocks = 9;
       var player,boardId;
      winningCombinations = [[0,1,2],[3,4,5],[6,7,8],[0,3,6],[1,4,7],[2,5,8],[0,4,8],[2,4,6]];


    $(document).ready(function(){

        buttonId = 0;

        for (var index = 0; index < blocks; index++) {
            button1 = document.createElement("button");

            if((index==2||index==5||index==8)&&(buttonId==3||buttonId==6||buttonId==9)){
                button1.innerHTML="\r\n"+"<br>";
            }

            button1.innerHTML = " + " ;
            button1.id = buttonId;
            button1.setAttribute("value", buttonId);
            button1.setAttribute("text", buttonId);

            button1.style.fontFamily = "Times New Roman";
            button1.style.backgroundSize = "50px";
            button1.style.backgroundColor = "#C0C0C0";
            button1.style.fontSize = "25px";
            button1.style.marginBottom = "10px";
            button1.style.marginLeft = "5px";   
            button1.style.marginRight = "5px";
            document.body.appendChild(button1);
            buttonId++;



    }
});

  </script>

</body>

var表=[];
var块=9;
var-player,boardId;
获胜组合=[[0,1,2]、[3,4,5]、[6,7,8]、[0,3,6]、[1,4,7]、[2,5,8]、[0,4,8]、[2,4,6];
$(文档).ready(函数(){
buttonId=0;
对于(变量索引=0;索引<块;索引++){
button1=document.createElement(“按钮”);
如果((索引=2 | |索引=5 | |索引=8)和&(按钮=3 | |按钮=6 | |按钮=9)){
button1.innerHTML=“\r\n”+”
”; } button1.innerHTML=“+”; button1.id=buttonId; button1.setAttribute(“值”,buttonId); button1.setAttribute(“文本”,buttonId); button1.style.fontFamily=“Times New Roman”; 按钮1.style.backgroundSize=“50px”; 按钮1.style.backgroundColor=“#c0”; button1.style.fontSize=“25px”; button1.style.marginBottom=“10px”; button1.style.marginLeft=“5px”; 按钮1.style.marginRight=“5px”; document.body.appendChild(按钮1); buttonId++; } });
您追加
br
的条件不正确,我在

var表=[];
var块=9;
var-player,boardId;
获胜组合=[[0,1,2]、[3,4,5]、[6,7,8]、[0,3,6]、[1,4,7]、[2,5,8]、[0,4,8]、[2,4,6];
$(文档).ready(函数(){
buttonId=0;
对于(变量索引=0;索引<块;索引++){
button1=document.createElement(“按钮”);
button1.innerHTML=“+”;
button1.id=buttonId;
button1.setAttribute(“值”,buttonId);
button1.setAttribute(“文本”,buttonId);
button1.style.fontFamily=“Times New Roman”;
按钮1.style.backgroundSize=“50px”;
按钮1.style.backgroundColor=“#c0”;
button1.style.fontSize=“25px”;
button1.style.marginBottom=“10px”;
button1.style.marginLeft=“5px”;
按钮1.style.marginRight=“5px”;
document.body.appendChild(按钮1);
如果((指数=2 | |指数=5 | |指数=8)){
document.body.appendChild(document.createElement('br'));
}
buttonId++;
}
});

CSS解决方案 您可以通过使用CSS来实现这一点,将按钮显示为块并将其向左浮动

每隔三个按钮清除一次

var表=[];
var块=9;
var-player,boardId;
获胜组合=[
[0, 1, 2],
[3, 4, 5],
[6, 7, 8],
[0, 3, 6],
[1, 4, 7],
[2, 5, 8],
[0, 4, 8],
[2, 4, 6]
];
$(文档).ready(函数(){
buttonId=0;
对于(变量索引=0;索引<块;索引++){
button1=document.createElement(“按钮”);
如果((索引=2 | |索引=5 | |索引=8)和&(按钮=3 | |按钮=6 | |按钮=9)){
button1.innerHTML=“\r\n”+”
”; } button1.innerHTML=“+”; button1.id=buttonId; button1.setAttribute(“值”,buttonId); button1.setAttribute(“文本”,buttonId); button1.style.fontFamily=“Times New Roman”; 按钮1.style.backgroundSize=“50px”; 按钮1.style.backgroundColor=“#c0”; button1.style.fontSize=“25px”; button1.style.marginBottom=“10px”; button1.style.marginLeft=“5px”; 按钮1.style.marginRight=“5px”; document.body.appendChild(按钮1); buttonId++; } });
按钮{
显示:块;
浮动:左;
}
按钮:第n个类型(3n+1){
明确:两者皆有;
}

可能重复的:
