我有一個HTML表單,我想驗證一個正則表達式。我有一個名爲emailRegex的方法中包含的正則表達式,然後在validateEmail方法中調用它。 I「m如果一個錯誤,當它試圖將validateEmail內叫我emailRegex方法誰能告訴我,我做錯了什麼在這裏Javascript正則表單驗證
var validation={
emailRegex: function() {//new email Regular Expression for validateEmail method
return /^(([a-zA-Z0-9_\-\.]+)@([a-zA-Z0-9_\-\.]+)\.([a-zA-Z]{2,5}){1,25})+ ([;.](([a-zA-Z0-9_\-\.]+)@([a-zA-Z0-9_\-\.]+)\.([a-zA-Z]{2,5}){1,25})+)*$/;
},
validateEmail: function(value) {
var regex = this.emailRegex;//takes value found in emailRegex
var offensiveWords = new RegExp(/\b(hate|notCool)b/); //offensive words regular expression
var email = document.getElementById("email");
var compactEmail = function(){//takes the value of the email form element and takes out any white spaces
var emailValue = email.value;
var compacted = emailValue.replace(" ","");
return compacted;
}
if(!regex.test(compactEmail())){//checks for a valid email address against regex from emailRegex method
alert("Please enter a valid email address");
email.focus();
return false;
}
if(!offensiveWords.test(compactEmail())){//checks for the offensive words found in offensiveWords regular expression.
alert("Your email address contains an offensive word");
email.focus();
return false;
}
return true;
}
}
