If you are using jquery just use

$(document).ready(function(){
 $("your div id").text("your text");
});

Also don't forget to use the jquery library in your code as

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.0/jquery.min.js"></script>

We use this very frequently

document.getElementById("<Your DIV ID>").innerHTML=<value of inner HTML>;

So in short you may need to use one of the following -

document.getElementById(id).innerHTML = new HTML
document.getElementById(id).attribute=new value

Write validation functions and modify the onSubmit event Handler in the form code to validate the following form fields:

  1. Phone Number
    • Must be entered
    • Must be below format
    XXX-XXX-XXXX
    XXX.XXX.XXXX
    XXX XXX XXXX

My form is somewhat like this:-

 <form id="form1" method="post" name="form1">
 //...fields like firstname, email......
 <button type="submit" id="submit" name="submit" onclick="validate(this)">SUBMIT</button>
 < /form>

The javascript validate function:-

function validate(ref)
{
    if(document.form1.firstname.value=="")
    {
            window.alert("First Name Cannot be Blank");
            return;
    }

    // validating other fields like email... If any field is invalid return 
    document.form1.action="response"
    document.form1.submit()
} 

Now what the problem is suppose I left the firstname field blank and click submit button then windows alerts that firstname field is mandatory....and as soon as I click the OK button in alert form the form is posted...

Now question is that I assign the action attribute after validating all the fields and if any one is invalid the function returns in which case action attribute of the form is not assigned then how the form is submitted.
The form should have been submitted after all the validation tests will have been successful and controls would have reached document.form1.submit(). And what is the solution for this.

I am using Python Flask and rendering template using jinja2.
