我对 jQuery 相当陌生,所以我的代码可能不是最精简的。我正在尝试编写自己的表单验证脚本,一切正常。
但为了减少 CSS,我想在同一个 div 标签中显示每个表单输入的错误消息。所以valid_prompt的div标签被放置在每个输入字段之后。
我目前遇到的问题是所有错误消息都显示在 div 标签的第一次出现中,这是预期的,但我需要某种方法将每个唯一输入字段链接到显示错误的 div。
表单输入示例
<input name="email1" id="email1" type="text" size="30" maxlength="80"
value="<?php echo "$email1"; ?>" /><span id="valid_prompt"></span>
<br/>
<br/>
<label><span class="reqfieldstar"> * </span>Confirm E-mail Address:</label>
<input name="email2" id="email2" type="text" size="30" maxlength="40" value="<?php echo "$email2"; ?>" /><span id="valid_prompt"></span>
jQuery代码
var form = $("#SignupForm"); // Id of Form
var email = $("#email1"); // Email Address ID
var email_compare = $("#email2"); // Compare Email Address ID
var valid_prompt = $("#valid_prompt");
var lettersReg = /^([a-zA-Z,-]|\s)*$/;
var emailReg = /^(\S+@\S+(\.\S+)*\.(\S{2,4}))?$/i;
email.keyup(validateEmail);
email_compare.keyup(validateEmail_Compare);
firstname.keyup(validateFirstname);
surname.keyup(validateSurname);
email.blur(validateEmail);
email_compare.blur(validateEmail_Compare);
firstname.blur(validateFirstname);
surname.blur(validateSurname);
form.submit(function() {
if (validateEmail() && validateEmail_Compare() && validateFirstname() && validateSurname()) {
return true;
} else {
return false;
}
});
function validateEmail() {
if (email.val().length == 0) {
email.addClass("error");
valid_prompt.removeClass("correct");
valid_prompt.text("You Must Enter Your E-mail Address");
valid_prompt.removeClass("correct");
valid_prompt.addClass("error");
return false;
} else {
if (!emailReg.test(email.val())) {
email.addClass("error");
valid_prompt.removeClass("correct");
valid_prompt.text("Please Enter a Valid E-mail Address");
valid_prompt.removeClass("correct");
valid_prompt.addClass("error");
return false;
} else {
email.removeClass("error");
valid_prompt.text("");
valid_prompt.addClass("correct");
valid_prompt.removeClass("error");
return true;
}
}
} // Email Function End
function validateEmail_Compare() {
if (email_compare.val().length == 0) {
email_compare.addClass("error");
valid_prompt.removeClass("correct");
valid_prompt.text("You Must Confirm Your E-mail Address");
valid_prompt.removeClass("correct");
valid_prompt.addClass("error");
return false;
} else {
if (!emailReg.test(email_compare.val())) {
email_compare.addClass("error");
valid_prompt.removeClass("correct");
valid_prompt.text("Please Enter a Valid E-mail Address");
valid_prompt.removeClass("correct");
valid_prompt.addClass("error");
return false;
} else {
if (email.val() != email_compare.val()) {
email_compare.addClass("error");
valid_prompt.removeClass("correct");
valid_prompt.text("Your E-mail Addresses Do Not Match");
valid_prompt.removeClass("correct");
valid_prompt.addClass("error");
return false;
} else {
email_compare.removeClass("error");
valid_prompt.text("");
valid_prompt.addClass("correct");
valid_prompt.removeClass("error");
return true;
}
}
}
} // Email Compare Function End
