brokenRules
An array of the validation rules that failed.
Array<RequiredRule | NumericRule | RangeRule | StringLengthRule | CustomRule | CompareRule | PatternRule | EmailRule | AsyncRule>
This array contains broken rules from all Validators in the validation group.
The validation rules are checked in the following order:
All the sync rules are checked in the same order as in the validationRules array. If a sync rule is broken, no further checks are performed and the brokenRules array contains only this rule.
If the sync rules successfully pass the checks, all the async rules are checked simultaneously. If any async rule is broken, it is added to the brokenRules array with other broken async rules.
complete
Promise<dxValidationGroupResult> (jQuery or native)
This promise exists only when the status is "pending". Check the status before you attach callback functions to that promise.
In the following example, a button validates a group of editors with async rules. The status is checked in the onClick event handler:
jQuery
$(function() { const validationGroupName = "myValidationGroup"; $("#textBox").dxTextBox({ ... }) .dxValidator({ validationGroup: validationGroupName, validationRules: [{ type: "async", validationCallback: function(params) { // ... } }] }); $("#dateBox").dxDateBox({ ... }) .dxValidator({ validationGroup: validationGroupName, validationRules: [{ type: "async", validationCallback: function(params) { // ... } }] }); $("#button").dxButton({ validationGroup: validationGroupName, onClick: function(e) { const res = e.validationGroup.validate(); res.status === "pending" && res.complete.then((r) => { console.log(r.status); }); } }); });

- "valid" - all validation checks passed
- "pending" - there are pending (not fulfilled or rejected) async rules
- "invalid" - all validation checks are completed, but there are broken rules
