Question

我正在尝试设置最大限制。当按下任何2个按钮时，必须有一个动作（其他按钮被禁用）。

这是wordpress中后置反应的代码。我先尝试过这个链接。- \*\*([^*]+)\*\*但我不能。我如何计算点击次数并设置最大点击次数限制？

var regex = /(?:-\s+\*+)([\w\s\w]+)/g;
var str = `__**Cubone  100%**__Panama

Despawns @ 03:40:33am __**(29m 55s)**__
Weather Boost: **Clear :sunny:**
Level: 19 - IV: 100% (15/15/15) - CP: 5120
- **Rock Smash**
- **Dig**

**Map Info**: https://maps.google.com/?q=35.1224486753,-106.6278869713`;
var m;

while ((m = regex.exec(str)) !== null) {
    // This is necessary to avoid infinite loops with zero-width matches
    if (m.index === regex.lastIndex) {
        regex.lastIndex++;
    }
    console.log(m[1]);
}

此处还有php文件。

 (function($) {
      $(document).ready(function() {
        $('#zuzu_viral_reactions li').click(function() {
          var unreact = ($(this).hasClass("clicked") ? true : false);
          var id = $(this).parent().data("postId") || $(this).parent().data("post-id");
          var url = zvr_data.ajax_url;
          var reaction = $(this).data().reaction;
          $.post(url, { postid: id, action: 'zvr_react', reaction: reaction, unreact: unreact }, function(data) {
            console.log("Ajax: " + data);
      });

      $(this).toggleClass("clicked");

      var howMany = parseInt($(this).find('span').text());
      if (howMany > 0) {
        if ($(this).hasClass("clicked")) {
          howMany += 1;
        } else {
          howMany -= 1;
        }
      } else {
        howMany = 1;
      }
      $(this).find('span').text(howMany);

    });


  });

})(jQuery);

document.addEventListener("touchstart", function() {}, true);

if ('createTouch' in document) {
  try {
    var ignore = /:hover/;
    for (var i = 0; i < document.styleSheets.length; i++) {
      var sheet = document.styleSheets[i];
      for (var j = sheet.cssRules.length - 1; j >= 0; j--) {
        var rule = sheet.cssRules[j];
        if (rule.type === CSSRule.STYLE_RULE && ignore.test(rule.selectorText)) {
          sheet.deleteRule(j);
        }
      }
    }
  } catch (e) {}
}

您可以通过jquery解决此问题，并通过以下代码获取最大长度事件

<label for="name">Input 1: maxlength=10</label>
<input type="text" maxlength="10" id="input-1" value="Allen"/>

$("#input-1").maxlength();

// get maxlength and other event
$("input").bind("update.maxlength", function(event, element, lastLength, length, maxLength, left){
console.log(event, element, lastLength, length, maxLength, left);
});

如何设置最大按钮单击限制？
