Question

我认为这很容易，但我无法弄清楚。

$output  .= '<div class="hotel-container">
                                    <div class="row">
                                        <div class="col-md-4">  
                                            <img src="admin/'.$row['main_picture'].'"class="img-responsive hotelpic">
                                        </div>

                                        <div class="col-md-5">
                                            <h5 class="hotelname">'.$row['resort_name'].'</h5>
                                            <h5 class="address"><i class="fa fa-map-marker" aria-hidden="true"></i>&nbsp;&nbsp;&nbsp;'.$row['resort_address'].'</h5>
                                        </div>

                                        <div class="col-md-3">
                                            <h5 class="price">&#8369; '.$row['resort_total_cost'].'</h5>
                     /*here's the button*/  <button class="btn btn-warning" id="viewinfo">View more info</button>
                                        </div>
                                    </div>

                                </div>';

结果将是：var str = "How are you doing today?"; var res = str.split(/\s+/g);。当用户添加字符＆＃34; |＆＃34;在这两个词之间

How,are,you,doing,today?

结果应该是：var str = "How are you |doing today?";

Answer 1

试试这个：

var source = "How are you |doing today?";
var result = source
  .split(/\s+(?!\|)/g)
  .map(function(segment) {
    return segment.replace(/((\s+)\|)/g, '$2');
  });
  
console.log(result);

首先使用否定先行将字符串split放到管道符（|）未跟踪的空格序列上，然后结果数组被映射，例如每个段的空格序列后面跟着一个管道字符，只替换每个匹配组（$2）的空白部分（$1）。

如果在Extendscript中没有实现Array.map，这是使用常规for循环的另一个示例：

var source = "How are you |doing today?"; var rawArray = source.split(/\s+(?!\|)/g); var result = []; for (var i = 0; i < rawArray.length; i++) { result[i] = rawArray[i].replace(/((\s+)\|)/g, '$2'); } console.log(result);

Answer 2

您无法执行 split所描述的内容。你可以使用负前瞻断言（/ (?!\|)/）来接近，但它会在字符串中留下|：

var str = "How are you |doing today?";
var arr = str.split(/ (?!\|)/);
console.log(arr);

......所以我们必须做得更多。可能最简单的事情是在拆分后用空格替换空格+栏：

var str = "How are you |doing today?";
var arr = str.split(/ (?!\|)/).map(function(s) {
  return s.replace(/ \|/g, ' ');
});
console.log(arr);

或在ES2015 +中：

const str = "How are you |doing today?";
const arr = str.split(/ (?!\|)/).map(s => s.replace(/ \|/g, ' '));
console.log(arr);

Answer 3

首先用管道替换所有空白区域。每次遇到两个或更多管道时，请用空格替换。然后通过管道分割：

＆＃13;

var str = `How  are you |doing today?
fine | thanx`;
var arr = str.replace(/ {1,}/g,"|").replace(/\|{2,}/g," ").split(/\||\n/);
console.log(arr);

Javascript - 按空格分割字符串，并按＆＃34; |＆＃34;加入两个单词
