This seemed like something simple, but I am stumped. I have a form and want a field to be required if the value of another field is greater than zero. While the validation actually works and allows me to submit, the error tooltip doesn't clear when I change the value back to zero.
In the fiddle, if the Misc amount is greater than 0, i want the comments to be required, otherwise not required. As I said, the validation works, but the validation message doesn't get cleared.
jQuery(document).ready(function() {
//Initialize the tooltips
jQuery('.tooltip').tooltipster({
contentAsHTML: true
});
jQuery('#frmForm :input').each(function() {
var tipelement = getTipContainer(this);
jQuery(tipelement).tooltipster({
trigger: 'custom',
onlyOne: false,
position: 'right',
multiple: true,
autoClose: true
});
});
jQuery("#frmForm").validate({
ignore: [],
rules: {
MISCComments: {
required: function(element) {
return jQuery("#MISCAmount").val() > 0;
}
}
},
messages: {
MISCComments: "Explain what this payment is for."
},
errorPlacement: function(error, element) {
var $element = jQuery(element),
tipelement = element,
errtxt = jQuery(error).text(),
last_error = '';
tipelement = getTipContainer(element);
last_error = jQuery(tipelement).data('last_error');
jQuery(tipelement).data('last_error', errtxt);
if (errtxt !== '' && errtxt != last_error) {
jQuery(tipelement).tooltipster('content', errtxt);
jQuery(tipelement).tooltipster('show');
}
},
success: function(label, element) {
var tipelement = getTipContainer(element);
jQuery(tipelement).tooltipster('hide');
}
});
//this function selects a container for 'group' elements like
//check box /radio groups
function getTipContainer(element) {
var tipelement = element;
if (jQuery(element).is(":checkbox") || jQuery(element).is(":radio")) {
tipelement = jQuery(element).parents('.container').get(0);
}
return tipelement;
}

</form>Since you're dynamically changing the rule, you'll need to programmatically force validation of this field when the value of the dependent field is edited.
jQuery('[name="MISCAmount"]').on('blur keyup', function() {
jQuery('[name="MISCComments"]').valid(); // force validation
});
Also...
The success function will not re-fire on an "optional" field when this field is blanked out or the rules are changed. This is the root issue. Your field is dynamically changed from required into "optional" and there is no way to force the success function to re-fire for this case.
The solution is to use the unhighlight function instead of success, which fires every single time a field is evaluated for validity. The following code attaches the show and hide methods to these default functions.
unhighlight: function(element, errorClass, validClass) {
$(element).removeClass(errorClass).addClass(validClass).tooltipster('hide');
},
highlight: function(element, errorClass, validClass) {
$(element).addClass(errorClass).removeClass(validClass).tooltipster('show');
},

Quoting myself from this other answer:
"I also replaced the
successcallback withunhighlight. On "optional" fields, the error message was never removed when the field was subsequently blanked out... this is because thesuccessfunction does not fire under these circumstances."
I also recommend that you upgrade to ToolTipster version 4 and rework your code for such. Version 4 contains some new/improved methods such as open and close, which makes a little more sense for toggling tooltips, and works very well with highlight and unhighlight.
