JS sensitive word filtering code

Filter sensitive and bad vocabulary. This article mainly talks about two ways to filter sensitive words.

I directly reflect it in the form of a function here, that is, just call the function directly when using it.

Method 1, RegExp()

function filter() {

  // Get the inputContent content of the input box  var inputContent = ;

  // Multiple sensitive words are displayed directly in an array here  var arrMg = ["fuck", "tmd", "damn it"];

  // The content displayed --showContent  var showContent = inputContent;

  // Regular expression  // \d Match number
  for (var i = 0; i &lt; ; i++) {

    // Create a regular expression    var r = new RegExp(arrMg[i], "ig");

    showContent = (r, "*");
  }
  // The content displayed --showInput   = showContent;
}

Method 2: replace()

function filtion(){
  var inputContent = ;

  // Multiple sensitive words  var arrMg = ["fuck", "tmd", "damn it"];

  var showContent = inputContent;

  for (var i = 0; i &lt; ; i++) {

    // replace will only replace the first one. If there is the same content in the future, it will not be replaced.    showContent = (arrMg[i], "*");
  }

   = showContent;
}

Both methods have been written, one is a regular expression, and the other is the object method replace().

Add HTML code below, which may be better.

&lt;textarea  &gt; &lt;/textarea&gt;

  &lt;input type="button" value="Convert" onclick="filter()"/&gt;

  &lt;textarea &gt;&lt;/textarea&gt;

Of course, there are still several methods for filtering sensitive words, such as JQ, and of course, it is also possible to use some current mainstream front-section frameworks, such as angular, vue, etc., which will have their own filters.

However, in real development, filtering this area is usually left to the backend method.

that's all.

The above is all the content of this article. I hope it will be helpful to everyone's study and I hope everyone will support me more.
