If I do this on vue:
<input pattern="\d+">
It gets properly validated, but I get a popup with a message "Please match the requested format".
Is there any way to change this message? I can't find the documentation on the accepted validation tags.
JSFiddle: http://jsfiddle.net/ovz5p3wt/
so, as noted in comments, the way to do it is to use oninvalid and setCustomValidity
<input pattern="\d+" oninvalid="setCustomValidity('please use a number')">
However, if you want to do it using a script (since you are tagging at as vue) here is another solution that allows you to dynamically change the value you can use the script version. unfortunately @oninvalid doesn't seem to be supported by vue, so you'd need to set the functionality using $refs
updateCustomValidity(lang){
var el = this.$refs.el;
el.oninvalid = el.setCustomValidity(this[lang].message);
}
new Vue({
el: "#app",
data() {
return {
lang: 'en',
en: {
message: 'nope, sorry',
},
fr: {
message: 'sacre bleu'
}
}
},
watch: {
lang: {
handler(lang) {
this.updateCustomValidity(lang);
}
}
},
methods: {
updateCustomValidity(lang){
var el = this.$refs.el;
el.oninvalid = el.setCustomValidity(this[lang].message);
}
},
mounted() {
this.updateCustomValidity(this.lang);
}
