代码如下:

String.prototype.Trim = function() {

var m = this.match(/^\s*(\S+(\s+\S+)*)\s*$/);

return (m == null) ? "" : m[1];

}

String.prototype.isMobile = function() {

return (/^(?:13\d|15[89])-?\d{5}(\d{3}|\*{3})$/.test(this.Trim()));

}

String.prototype.isTel = function()

{

//"兼容格式: 国家代码(2到3位)-区号(2到3位)-电话号码(7到8位)-分机号(3位)"

//return (/^(([0\+]\d{2,3}-)?(0\d{2,3})-)?(\d{7,8})(-(\d{3,}))?$/.test(this.Trim()));

return (/^(([0\+]\d{2,3}-)?(0\d{2,3})-)(\d{7,8})(-(\d{3,}))?$/.test(this.Trim()));

}

function chkForm() {

with(document.form1){

if (tel.value.isMobile()||tel.value.isTel()) {

tel.value = tel.value.Trim();

alert("您的电话/手机号码是:" + tel.value);

return true;

}

else {

alert("请输入正确的手机号码或电话号码\n\n例如:13916752109或0712-3614072");

tel.focus();

return false;

}

}

}
