Dear Experts,

I have a doubt in HTML5 asp.net

HTML

<form action="#" method="post" id="commentform" onsubmit="return false">
       <p class="comment-form-author">Name *<input id="author" name="author" type="text" value="" size="30" aria-required="true" required="required" /></p>
       <p class="comment-form-email">Email<input id="email" name="email" type="text" value="" size="30" /></p>

       <p class="comment-form-rating"><label for="rating">Rating</label>
       <select name="rating" id="rating" required="required">
           <option value="">Rate…</option>
           <option value="5">Perfect</option>
           <option value="4">Good</option>
           <option value="3">Average</option>
           <option value="2">Not that bad</option>
           <option value="1">Very Poor</option>
       </select>
       </p>


       <p class="form-submit">
       <input name="submit" type="submit" id="submit" value="Submit Review" />

       </p>
   </form>

On the above code i have set a required HTML5 validation on "author" input also the "select"

JavaScript

$(document).ready(function () {

    $("#submit").click(function () {

        var _rating = document.getElementById('rating').options[document.getElementById('rating').selectedIndex].value;
        var _author = document.getElementById('author').value;
        var _email = document.getElementById('email').value;
        var _comment = document.getElementById('comment').value;


        var data = [
           {
               "_author": _author, "_email": _email, "_rating": _rating, "_comment": _comment
           }];


        $.ajax(
             {
                 type: "POST",
                 url: "Item_desc.aspx/Save_Comment",
                 dataType: "json",
                 data: JSON.stringify({ Cust_Comments: data }),
                 contentType: "application/json; charset=utf-8",
                 success: function (json) {

                    

                 }

             });




         });

});

And i have used Ajax JSON for sending datas to the code behind in asp.net.....

But when i click the button then the validation will catch but it also fire the the click event and send the values to the code behind....

I need to stop fire the click event when the validation catches...

Thanks

Solution 2

Try this
$('#submit').click(function(){
if($("form")[0].checkValidity()) {
//your form execution code
}else console.log("invalid form");
});
