如何避免每次运行程序时更改单元格大小的数字? 我希望在数字之间具有相等的间距,而不会从左到右移动单元格。
var arr = new Array(5);
var i = 0, j, n;
var OK = true;
var printThis = " ";
var table = "<table style = font-size:25px; >";
while (i < arr.length) {
n = Math.floor((Math.random() * 35) + 1);
for (j = 0; j < i; j++) {
if (arr[j] == n) {
OK = false;
}
}
if (OK) {
arr[i] = n;
table += "<td>" + arr[i] + "</td>";
i++;
}
OK = true;
}
table += "</table>";
document.getElementById("demo").innerHTML = table;

将静态宽度设为td
var arr = new Array(5);
var i = 0,
j, n;
var OK = true;
var printThis = " ";
var table = "<table style = 'font-size:25px;'>";
while (i < arr.length) {
n = Math.floor((Math.random() * 35) + 1);
for (j = 0; j < i; j++) {
if (arr[j] == n) {
OK = false;
}
}
if (OK) {
arr[i] = n;
table += "<td width='25px'>" + arr[i] + "</td>";
i++;
}
OK = true;
}
table += "</table>";
document.getElementById("demo").innerHTML = table;
<div style='border:1px solid black;display:inline-block' id='demo'></div>

这是一个使用div而不是table的解决方案,以防某些人有一天需要这个。在具有固定宽度的div内均匀显示五个数字(一个或两个数字)。
CSS
.container
{
display:flex;
justify-content:space-between;
width: 125px;
font-size:25px;
border: 1px solid #000;
}
.item
{
display:inline;
}
javascript:
var arr = new Array(5);
var i = 0, j, n;
var OK = true;
var printThis = " ";
var table = "<div class='container'>";
while (i < arr.length) {
n = Math.floor((Math.random() * 35) + 1);
for (j = 0; j < i; j++) {
if (arr[j] == n) {
OK = false;
}
}
if (OK) {
arr[i] = n;
table += "<div class='item'>" + arr[i] + "</div>";
i++;
}
OK = true;
}
table += "</div>";
document.getElementById("demo").innerHTML = table;
HTML:
<div style='border:1px solid black;display:inline-block' id='demo'></div>
