This picture shows the result after we exchange:測試
Below is this project's code:this
1 <!DOCTYPE html> 2 <html> 3 <head lang="en"> 4 <meta charset="UTF-8"> 5 <title>RegExp</title> 6 </head> 7 <script> 8 function strreplace(){ 9 var str=document.getElementById("str").value; 10 var newstr=str.replace(/paul/g,"Ringo"); 11 document.getElementById("demo").innerHTML = newstr; 12 } 13 </script> 14 <body> 15 請輸入一串帶有「paul」(小寫)的單詞串,不一樣單詞用<br>空格隔開,點擊「替換」,可將「paul」替換成「Ringo」. 16 <br><br><br>你能夠複製這段字符進下框測試:paul like Spaul Paul paul 17 <br><br>會發現全部的「paul」都被替換成「Ringo」。 18 <br><br><br><input type="text" name="str" id="str"> 19 <input type="button" value="替換" onclick="strreplace()"> 20 <br><br>替換後:<p id="demo"></p> 21 </body> 22 </html>
