I have an index page, which contains a form, fill in the form and sends the data to a URL, which captures the input, and does the search in the database, returning a JSON. How do I get this JSON, and put it on another HTML page using Javascript?
Form of index:
<form action="{{ url_for('returnOne') }}", method="GET">
<p>Nome: <input type="text" name="nome" /></p>
<input type="submit" value="Pesquisar">
</form>
My function that returns JSON:
@app.route('/userQuery', methods=['GET'])
def returnOne():
dao = Dao()
nome = request.args.get('nome')
return jsonify(json.loads(dao.select(nome)))

You can use jQuery's
$.get('http://localhost:8080/userQuery');to store the JSON to a local variable. – SomeGuyOnAComputer Commented Mar 31, 2018 at 18:11 - and how can i do this? and to call another page html? where I call the page in return? – Matheus Alcântara Commented Mar 31, 2018 at 18:16
- I need to get the json and call another page html, i can do this with one route? – Matheus Alcântara Commented Mar 31, 2018 at 18:18

Reset to default 6Your HTML page after you submit the form. let's call it response.html
<!DOCTYPE html>
<html>
<head>
<title>hello</title>
</head>
<body>
<p id="test"></p>
<p id="test1"></p>
<script>
var b = JSON.parse('{{ a | tojson | safe}}');
document.getElementById('test').innerHTML = b.test;
document.getElementById('test1').innerHTML = b.test1;
console.log(b);
</script>
</body>
</html>
Your flask function that sends JOSN and redirects to response.html
@app.route('/userQuery', methods=["POST", "GET"])
def returnOne():
a = {
"test": "abcd",
"test1": "efg"
}
return render_template("response.html", a=a)
Use ajax request. This plugin transform the submit button in your HTML form to an Ajax submit
<script>
$(document).ready(function() {
// bind 'myForm' and provide a simple callback function
$('#myForm').ajaxForm(function(response) {
var result = jQuery.parseJSON(response);
$('#someDiv').innerHTML = result.res
});
});
</script>
Use the correct form Id
