VisualizaçõesHow to validate a zipcode text field and add HTML in case of error on submitting the form?
The jQuery code below alerts the user in case of incorrect zip code entered by attaching the change event to it. I would like to validate zip code entered in the text field on form in a landing page and add a bit of HTML in case of error on submitting the form. Could you please guide me on how to do it.
HTML for the input:
<div class="ff-el-input--content"><input type="text" name="address_1[zip]" id="ff_241_address_1_zip_" class="ff-el-form-control" placeholder="Zip"></div>
jQuery to validate:
jQuery("input:text[name='address_1[zip]']").change(function(e) {
if (!jQuery(this).val().match(/^\d{5}(?:[-\s]\d{4})?$/)) {
alert("Please enter a valid zip code");
jQuery("input[name='address_1[zip]']").val("");
return false;
}
});
When validation fails, I need to add the div below to right after the input text field.
<div class="error text-danger">This field is required</div>
Submit element:
<button type="submit" class="ff-btn ff-btn-submit ff-btn-lg">Submit</button>

What you need are the functions after() and remove().
jQuery("input:text[name='address_1[zip]']").change(function(e) {
if (!jQuery(this).val().match(/^\d{5}(?:[-\s]\d{4})?$/)) {
alert("Please enter a valid zip code");
jQuery("input[name='address_1[zip]']").val("");
if ($('.error').length == 0) {
$(this).after('<div class="error text-danger">This field is required</div>');
}
} else {
$('.error').remove();
}
});
