无法弄清楚如何在密码测试regexp上显示自定义消息。
关于submition,我有下一个正则表达式可以正常工作:
[a-zA-Z]{1,5} -> min 6 or symbols. must contain digits
[0-9]{1,5} -> min 6 or symbols. must contain letters
这真的很奇怪,但下一个:
[^\n]{6,} -> min 6 or more symbols (means that having letters and digits)
如果我尝试用以下代替:
[a-zA-Z0-9]{1,5}
它不起作用。
所以当我使用时:
[a-zA-Z]{6,} -> digit is needed (we have 6 symbols)
[0-9]{6,} -> letter is needed (we have 6 symbols)
他们也没有通过。
答案 0 :(得分:0)
您可以尝试以下代码:
var ar=[/[a-zA-Z]{1,5}/,/[a-zA-Z]{6,}/,/[0-9]{6,}/,/[^\n]{6,}/];
var msg=["min 6 or symbols. must contain digits",
"min 6 or more symbols (means that having letters and digits)",
"digit is needed (we have 6 symbols)",
"letter is needed (we have 6 symbols)",
"min 6 or symbols. must contain digits"];
var line="123456";
for(i=0;i<ar.length;i++){
if(ar[i].test(line))
{ alert(msg[i]);
break;
}
}
