用到了html字符串校验，这里记录一下。
1 <html> 2 <head> 3 <script type="text/javascript"> 4 function on_click(){ 5 var email = document.getElementById("input1").value.trim(); 6 var telph = document.getElementById("input2").value.trim(); 7 8 if(email == "" ||telph == ""){ 9 alert("The email or telph is blank!!!"); 10 return false; 11 } 12 13 if (email.indexOf("@") == -1){ 14 alert("an @ is not in an email !!!"); 15 return false; 16 } 17 18 var re = /^([0-9]{3}-)?[0-9]{3}-[0-9]{4}$/; 19 if (re.test(telph) == false){ 20 alert("telph number is not match xxx-xxxx or xxx-xxx-xxxx") 21 return false; 22 } 23 24 alert("ok, email:" + email + ", telephone:" + telph); 25 return true; 26 } 27 </script> 28 </head> 29 30 <body> 31 email: <input id = "input1"> </input> <br> <!--必须有@--> 32 telph: <input id = "input2"> </input> <br> <!--必须满足xxx-xxxx or xxx-xxx-xxxx--> 33 <button type="button" onclick=on_click()>test</button> 34 </body> 35 </html>
如图：
校验两个字段均不能为空
校验email字段必须包含@
校验telph字段必须满足正则表达式
