Tanisha Gupta window.onload function runs js only after document is fully loaded ,basically it prevents js to be executed before Dom is fully loaded otherwise that would return null on accessing the elements like form that don't exist yet,you Don't need to write code inside that function if you are using script just before body tag, So document.querySelector("form") selects the form tag ,and form.onsubmit listens for submit event on form ,so when form is valid it executes whatever is passed inside the following function =()=>{ }; The above is es6 syntax for writing function in more readable and shorter way ,which is basically function(){ };

If it's a "post" form then that's something you have to handle from backend, could you explain where this form data is going?

Thanks guys but still there is an issue if we add this alert msg outside the form it works else it is not working and if add "required" to some data then our submission will not working acc that it will directly submit the form with showing them any alert msg regarding required details.You can recheck my code I have made that changes and it will be easy for uh to spot my query.

You can try this,listen for submit event on form, when all the required details are filled alert, "thanks for registration", var form=document.querySelector("form") form.onsubmit=()=>{ alert("thanks for registration"); }

In your form tag simply add Onsubmit="alert('thanks for registration')" as an attribute and value. Write single and double quotes are they are.

HI! Sis Tanisha Gupta You can add maxlength=10 in td tag that contains about phone number. As : <td><input type ="number" name="" maxlength="10" /></td> So,that ur code will be great enough to type phone number of 10 digits only. And I know that I didn't gave u the answer for ur question.Bcz,I'm a beginner to Js and started learning it just 2-3 days back. Correct me if I'm wrong. HAPPY CODING :)

Vishnu_kishore@473 Thanks for your suggestion but it will not work if we use type=number ,.But if we use type=text and we'll put maxlength attribute then it will work. Hope it will help you. But yes u can use <input type="tel" maxlength="10" /> or u can check my code for more info.
