javascript - PHP - 格式化字符串

Question

我使用 nba.com 网站 here 制定每日 NBA 日程表，但他们改变了它的布局，现在它包含更多数据。使用 PHP，我能够转动

这个:

5:00 PM ET
LA Clippers
Charlotte Hornets
Spectrum Center
Charlotte, NC
GAME PREVIEWBUY TICKETS

进入此:

5:00 PM ET
LA Clippers
Charlotte Hornets

但是，我很难将其变成这样:

5:00 PM ET LA Clippers @ Charlotte Hornets

我愿意接受建议，即使不是 PHP，我也可以将其他语言(例如 javascript/jquery)实现到用户脚本中。

有什么建议吗？

我目前正在使用的代码来清理我不想要的单词。

<?php
$name = $_POST["teamname"];
$words = array("Spectrum Center","Charlotte, NC","Bankers Life Fieldhouse","Indianapolis, IN","Wells Fargo Center","Philadelphia, PA","Quicken Loans Arena","Cleveland, OH","bc","Chesapeake Energy Arena","Oklahoma City, OK","Toyota Center","Houston, TX","American Airlines Center","Dallas, TX","GAME PREVIEWBUY TICKETS","Vivint Smart Home Arena","
Salt Lake City, UT");
$name = str_replace($words,"",$name);

if(isset($_POST["teamname"])){
    echo 'output:<br /><br /><textarea name="teamname" cols="80" rows="20" onclick="this.focus();this.select()">'.$name.'</textarea>';
    }
?>

编辑:添加我的代码。

Answer 1

在javascript中，您可以对字符串调用.split("\n")，然后使用Array.prototype.splice()向数组添加一个或多个元素，然后对数组调用 .join("") 以返回字符串。

let data = `5:00 PM ET
LA Clippers
Charlotte Hornets
Spectrum Center
Charlotte, NC
GAME PREVIEWBUY TICKETS`;

let arr = data.split("\n").slice(0, 3);
arr.splice(-1, 0, " @ ");
arr.splice(1, 0, " ");

console.log(arr.join(""));

给定 jsfiddle 的字符串，在第 26 行省略 "bc"，您可以使用 do..while 循环，递增变量 6 在下一个日期行之前跳过三行。

let data = `5:00 PM ET
LA Clippers
Charlotte Hornets
Spectrum Center
Charlotte, NC
GAME PREVIEWBUY TICKETS
7:00 PM ET
Milwaukee Bucks
Indiana Pacers
Bankers Life Fieldhouse
Indianapolis, IN

7:30 PM ET

Philadelphia 76ers
Wells Fargo Center

7:30 PM ET

let [arr, n, next, res] = [data.split("\n"), 0, 6, Array()];

do {
  let curr = arr.slice(n, n + 3);
  curr.splice(-1, 0, " @ ");
  curr.splice(1, 0, " ");
  res.push(curr.join(""));
  n += next;
} while (n + next < arr.length);

console.log(res);

var text = "";
var i;
for (i = 0; i < res.length; i++) {
    text += res[i] + "<br>";
}
document.getElementById("demo").innerHTML = text;

<div id="demo"></div>
