Customize error message and placement
17,312
You can change the default messages for a validation on a per property basis:
test: ko.observable().extend({
required: {
params: true,
message: "This is required"
}
})
You can use the validationMessage
binding to display the errors wherever you want:
<span data-bind="validationMessage: test"></span>
And you can use the decorateElement
and errorElementClass
options (or the other validation bindings) to add some custom classes on your inputs:
ko.validation.init({
decorateElement: true,
errorElementClass: 'err'
});

Currently the Knockout-Validation plugin automatically add this HTML element to my web page:
<span class="validationMessage">This field is required.</span>
- I want to change the "This field is required." text.
- I want to change the placement of the
<span>
HTML element. - I want to add a CSS class (
.err
, specifically) to my textbox so that I can add a red border.
How can that be done with Knockout-Validation?
