在移动设备上检测字符代码桌面设备

问题描述

我正在尝试在用户键入时使用jquery在按下的空格后添加Diez标记#.我已经从codepen.io创建了这个 演示 .

I am trying to add Diez tag # after the pressed space using jquery when user type. I have created this DEMO from codepen.io.

在此演示中，当您编写示例(how are you)时，javascript代码将像这样(#how #are #you)进行更改.

In this demo when you write for example (how are you) the javascript code will change it like this (#how #are #you).

如果您选中 演示 ，您会发现我已经使用过textInput.它在 Firefox 中不起作用，但是在移动设备上起作用.因此，如果我使用keypress，则代码可在 FireFox 上运行，而在移动设备上不可用.我的代码应该适用于所有设备.

If you check DEMO you can see I have used textInput. It isn't work in Firefox but working on mobile devices. So if I use keypress the codes are working on FireFox but not working on mobile. My code should be work with all devices.

在所有设备上运行我的代码的解决方案是什么?

What is the solution to work my code in all devices ?

这是完整的代码:

$(document).ready(function() {
   // Move cursor to the end.
   function placeCaretAtEndX(el) {
      el.focus();
      if (
         typeof window.getSelection != "undefined" &&
         typeof document.createRange != "undefined"
      ) {
         var range = document.createRange();
         range.selectNodeContents(el);
         range.collapse(false);
         var sel = window.getSelection();
         sel.removeAllRanges();
         sel.addRange(range);
      } else if (typeof document.body.createTextRange != "undefined") {
         var textRange = document.body.createTextRange();
         textRange.moveToElementText(el);
         textRange.collapse(false);
         textRange.select();
      }
   }

   // Define special characters:
   var charactersX =  [
      0,
      32,188,186,222,221,219,13
      // add other punctuation symbols or keys
   ];

   // Convert characters to charCode
   function toCharCodeX(char) {
      return char.charCodeAt(0);
   }

   var forbiddenCharactersX =  [
      toCharCodeX("_"),
      toCharCodeX("-"),
      toCharCodeX("?"),
      toCharCodeX("*"),
      toCharCodeX("\\"),
      toCharCodeX("/"),
      toCharCodeX("("),
      toCharCodeX(")"),
      toCharCodeX("="),
      toCharCodeX("&"),
      toCharCodeX("%"),
      toCharCodeX("+"),
      toCharCodeX("^"),
      toCharCodeX("#"),
      toCharCodeX("'"),
      toCharCodeX("<"),
      toCharCodeX("|"),
      toCharCodeX(">"),
      toCharCodeX("."),
      toCharCodeX(","),
      toCharCodeX(";")
   ];

   $(document).on("textInput", "#text", function(event) {
      var code = event.keyCode || event.which;
      if (charactersX.indexOf(code)>-1) {
         // Get and modify text.
         var text = $("#text").text();
         text = XRegExp.replaceEach(text, [
            [/#\s*/g, ""],
            [/\s{2,}/g, " "],
            [XRegExp("(?:\\s|^)([\\p{L}\\p{N}]+)(?=\\s|$)(?=.*\\s\\1(?=\\s|$))","gi"),""],
            [XRegExp("([\\p{N}\\p{L}]+)", "g"), "#$1"]
         ]);
         // Save content.
         $("#text").text(text);
         // Move cursor to the end
         placeCaretAtEndX(document.querySelector("#text"));
      } else if (forbiddenCharactersX.indexOf(code)>-1) {
         event.preventDefault();
      }
   });
});

推荐答案

仅监听多个事件

$(document).on("textInput keydown", "#text", function(event) {
   // ...
}
