JS表单验证的代码(常用)

最近没有项目做，有点空余时间，小编把日常比较常用的js表单验证代码整理分享到编程之家平台，供大家学习，需要的朋友参考下吧！

注册验证：

rush:js;"> //验证密码为数字字母下划线 function CheckPwd(pwd) { var validStr = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMnopQRSTUVWXYZ0123456789_~/!@#$%^&*();-+.=,"; for (i = 0; i < pwd.length; i++) { if (validStr.indexOf(pwd.charat(i)) == -1) { return false; } } return true; } //验证邮箱格式 function checkemail(email) { var filter = /^([a-zA-Z0-9_\.\-])+\@(([a-zA-Z0-9\-])+\.)+([a-zA-Z0-9]{2,4})+$/; if (!filter.test(email)) { return false; } return true; } function isEmail(val) { return /^((([a-z]|\d|[!#\$%&'\*\+\-\/=\?\^_\`{\|}~]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])+(\.([a-z]|\d|[!#\$%&'\*\+\-\/=\?\^_`{\|}~]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])+)*)|((\x22)((((\x20|\x09)*(\x0d\x0a))?(\x20|\x09)+)?(([\x01-\x08\x0b\x0c\x0e-\x1f\x7f]|\x21|[\x23-\x5b]|[\x5d-\x7e]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(\\([\x01-\x09\x0b\x0c\x0d-\x7f]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF]))))*(((\x20|\x09)*(\x0d\x0a))?(\x20|\x09)+)?(\x22)))@((([a-z]|\d|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(([a-z]|\d|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])*([a-z]|\d|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])))\.)+(([a-z]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(([a-z]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])*([a-z]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])))\.?$/.test(val); } ///手机号码验证 function checktelephone(cellPhone) { var RegCellPhone = /^([0-9]{11})?$/; falg = cellPhone.search(RegCellPhone); if (falg == -1) { return false; } else { return true; } } //获取URL参数值 function getParameter(param) { var query = window.location.search; var iLen = param.length; var iStart = query.indexOf(param); if (iStart == -1) return ""; iStart += iLen + 1; var iEnd = query.indexOf("&",iStart); if (iEnd == -1) return query.substring(iStart); return query.substring(iStart,iEnd); }
