Issue
This is my app.py code:
@app.route('/index', methods=['GET', 'POST'])
def test_post():
theName=request.form['name']
theAge=request.form['age']
if theName and theAge:
return jsonify({'output':'Your name is '+theName+' , and your age is '+theAge+' , right?'})
return jsonify({'error': 'Missing Data!'})
This is my index.html code about Ajax:
<script>
$(document).ready(function () {
$('#form').on('submit', function (e) {
$.ajax({
data: {
name: $('#name').val(),
age: $('#age').val(),
},
type: 'POST',
url: '/index'
})
.done(function (data) {
$('#output').text(data.output).show();
});
e.preventDefault();
});
});
</script>
I want to know, if the entered name and age are empty, how can the returned 'Missing Data!' on the page. Thanks for your help very much!
Solution
You just have to paste this in your .data function,
.done(function(data){
if(data.error == "Missing Data!"){
alert("Missing Data");
}else{
$("#output").text(data.output);
}
Hope this works fine for you
