Is there a way to check for the application of the CSS3 :valid or :invalid pseudo-class on an input element using jQuery? I want to verify if the form element has passed CSS validation before allowing the submit button to be enabled.
Here are some methods I have attempted that proved unsuccessful:
if($("#el").is(":valid")) {
//...
}
if($("#el:valid").length == 0) {
//...
}
$("#el").attr("valid")
Following the update to jquery 1.10.2, I have verifed that utilizing the :valid selector functions as intended.
if($("#element").is(":valid")) {
//...
}
For Jquery versions older than 1.10.2, you can handle it in the following manner:
if ($('#subscriberNumTb:valid').length > 0) {
//add your code here
}
If you're interested in learning how to achieve this using pure JavaScript.
inputElement.checkValidity() // Returns `true` if valid, `false` if invalid
