本文实例讲述了JavaScript实现自动对页面上敏感词进行屏蔽的方法。分享给大家供大家参考。具体如下:
<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>
希望本文所述对大家的javascript程序设计有所帮助。
