We’re using this method to effectively limit the digits of the year field to 4. This method is automatically triggered, every time the value of the year changes.

In the code in the block above, you can also see a new watch section containing a year() method. The updateMonth() function works pretty much the same, but because there is no month in the year with a number larger than 12, we check if the newly entered value is below 2 before, to determine if the next field should be focused or not.

The logic behind this is the following: there is no day, in any given month, larger than 31, so if the user enters a number larger than 3, they usually (if they made no mistake) are done with entering the day and usually the next step is to enter the month.

If a value was entered and if this value is larger than 4 we want to focus the next field (if one is rendered).

In the updateDay() method, we check if the currently entered day value is not empty ( !) or the newly entered value is below 4. The event listener triggers an updateDay() or an updateMonth() method every time the user enters a new value in one of those fields. I’ll just quickly add a method which shows an alert, just so that it is easy to test.

The enter modifier ensures that the expression is only executed when the user releases the Enter key.

Clicking on left/right arrows on keyboard. We could do that by using the keyup event with the v-on directive, and the enter key modifier. 7 comments mocheaz commented on Clicking on the link.We also have added a second new event listener on the day and month fields. v-on click and keyup 1250 Closed mocheaz opened this issue on

#Vuejs keyup update#

We’re using the blur event to update the value of the affected field with a padded representation of the original value – so the day 1 becomes 01 or the year 100 becomes 0100 when the focus on an input field is lost. The first little improvement we can see directly in the template above, is that we’ve added event listeners onto every input element. Some changes are not detectable by keyup, for example pasting text from the context menu in a text input./ / export default Note: If you’re looking for a way to react to changes in an input’s value, you should use the input event. On the “pasting” side, MDN has explains it but it goes in the same direction: Removing lazy you will enforce input to happen and everything works as expected. Then hide and show the variants just with a css dynamic class. So i came up with this idea: use v-if and set condition to true only on the first mouseenter. Support Vue.js 2 > vue-esc>2.0.0 master Vue.js 1 > vue-esc1.0.0 I. Your v-model won’t update and the input value will be the initial value until keyup stops firing. With v-show it is too slow at first and with v-if the side variants render every time after mouseleave & again mouseenter so thats pretty awkward for the user. vue-esc Vue.js directive to add a document event listener on escape keyup. In short: keyup event will happen but input will not (with lazy). If you can remove the lazy modifier, do so and avoid problems with that As you’re just setting to false it runs just once (the keyup) so that is why it works after that. Once the keyup fires it impacts the behavior of the input (I don’t know how the orders go here but you can imagine that the lazy handler doesn’t know it has to save the new value yet) and it updates the input with the current value (which is not updated yet due lazy). My take here: as you’ve a lazy modifier the v-model is updated only once you “leave” the element so whenever you’re still typing the v-model value stays the same.

You will see that the problem happens forever.
