The example in this article describes how JavaScript can automatically block sensitive words on the page. Share it with everyone for your reference. The details are as follows:
<html> <head> <title>Bad Words Example</title> <script type="text/javascript"> function filterText(sText) { var reBadWords = /badword|anotherbadword/gi; return sText.replace(reBadWords, "****"); } function showText() { var oInput1 = document.getElementById("txt1"); var oInput2 = document.getElementById("txt2"); oInput2.value = filterText(oInput1.value); } </script> </head> <body> <P> <textarea rows="10" cols="50" id="txt1">badword anotherbadword</textarea><br /> <input type="button" value="Filter Bad Words" onclick="showText()" /></p> <P>Filtered Text:<br /> <textarea rows="10" cols="50" id="txt2"></textarea></p> </body> </html>
I hope this article will be helpful to everyone’s JavaScript programming design.
