How to fill href tag with data from json and when clicked use the selected value in form to post
Question
hope all of you have a really nice day. Im working on a project right now and i cant seem to get this right. I have the following Json.
{
"Error":200,
"Fecha":"6/19/2018",
"Nombreag":"Canchas de Tenis",
"Nombretges":"Reserva de cancha",
"horarios":[
{
"horaM":"1000",
"hora":"10:00AM"
},
{
"horaM":"1030",
"hora":"10:30AM"
},
{
"horaM":"1100",
"hora":"11:00AM"
},
{
"horaM":"1130",
"hora":"11:30AM"
},
{
"horaM":"1200",
"hora":"12:00PM"
},
{
"horaM":"1230",
"hora":"12:30PM"
},
{
"horaM":"1300",
"hora":"01:00PM"
},
{
"horaM":"1330",
"hora":"01:30PM"
},
{
"horaM":"1400",
"hora":"02:00PM"
},
{
"horaM":"1430",
"hora":"02:30PM"
},
{
"horaM":"1500",
"hora":"03:00PM"
},
{
"horaM":"1530",
"hora":"03:30PM"
},
{
"horaM":"1600",
"hora":"04:00PM"
},
{
"horaM":"1630",
"hora":"04:30P.M."
},
{
"horaM":"1700",
"hora":"05:00P.M."
}
]
}
And i would like to add a href link based on all the Json inside horarios. This is for a HTML form to make a POST to my api, i want to display "hora" in the List view and when clicked set the horaM value for using that selection to post.
I know i have to use Javascript DOM like this but cant get to work the onclick on the href pass that value to the variable and marked it as selected.
I was thinking maybe something like this to get the value.
<!DOCTYPE html>
<html>
<body>
<p>
<ul id="loadListview" data-role="listview" data-inset="true" >
<li><a href="#" id="1200" onclick="myFunction()">12:00PM</a></li>
<li><a href="#" id="1230" onclick="myFunction()">12:30PM</a></li>
<li><a href="#" id="1300" onclick="myFunction()">1:00PM</a></li>
<li><a href="#" id="1330" onclick="myFunction()">1:30PM</a></li>
</ul>
<p id="demo"></p>
<script>
function myFunction() {
var x = this.href;
document.getElementById("demo").innerHTML = x;
}
</script>
</body>
</html>
But im getting undefined value.
Thanks in advance for all your kind help and i greatly appreciate you taking the time for reading this.

In order to tell myFunction which a is clicked, you need to pass this to the onclick function, so it will look like this onclick="myFunction(this)"
<ul id="loadListview" data-role="listview" data-inset="true" >
<li><a href="#THIS_HREF" data-hora="1200" onclick="myFunction(this)">12:00PM</a> </li>
</ul>
<p id="demo">x</p>
and then in the function add argument a . Also i will recommend using data-{attribute} like so
<script>
function myFunction(a) {
var x = a.href; // "a" is the clicked element
document.getElementById("demo").innerHTML = x;
console.log(a.dataset.hora) // here is the data-hora attribute
return false;
}
</script>
