谢谢各位大哥热心帮忙，，问题搞定了，，解决思路如下； 1：先循环遍历找出字符串中的字母 2：在循环找出字符串中的数字。 3：然后在找字符串中不是字母，数字的， 4:判断如果这三个条件同时大于0的话符合条件，否则不符合； 代码如下：//----------begin-------------------------------------------------- function vPass(v_pw){ if(v_pw.length < 11){ Ext.MessageBox.alert('提示','密码长度不能小于11位'); return false; } var patrn_shuzi=/^[0-9]$/; var patrn_zimu=/^[a-z]|[A-Z]$/; var patrn_teshu=/^[^A-Za-z0-9]$/; var flag=0; var s = v_pw.split('');
for(var i=0;i<s.length;i++){ if (patrn_shuzi.exec(s[i])) { flag = flag+1; break; } } for(var i=0;i<s.length;i++){ if (patrn_zimu.exec(s[i])) { flag = flag+1; break; } } for(var i=0;i<s.length;i++){ if (patrn_teshu.exec(s[i])) { flag = flag+1; break; } } if (flag != 3) { Ext.MessageBox.alert('提示','密码必须由数字,字母,特殊符号组成！'); return false; } } // -------------end---------------
var reg = new RegExp("^[a-zA-Z0-9#$%]+$","gi");
alert(test.replace(reg,"").length==0?"Success":"Fault");

1：先循环遍历找出字符串中的字母
2：在循环找出字符串中的数字。
3：然后在找字符串中不是字母，数字的，
4:判断如果这三个条件同时大于0的话符合条件，否则不符合；
