本文實例講述了JavaScript實現自動對頁面上敏感詞進行屏蔽的方法。分享給大家供大家參考。具體如下:
<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>
希望本文所述對大家的javascript程序設計有所幫助。
