So, here's the deal: I have a JSON object saved in my web App at localStorage.
This JSON is being saved as a string, with JSON.stringify
, inside one of my functions, on the page load:
localStorage.setItem("MyData", JSON.stringify(data));
data is being saved like this:
[{"NAMEVAR":"Some Data 1","CODE":"1"},{"NAMEVAR":"Some Data 2","CODE":"2"}]
data is the result from a request. The data is being saved successfully at the home page, so i could use later. After that, i have to load up a form on another page, using what i got from data.
I have this select tag on the page:
<select id="mySelectID" name="select" class="main-form">
<option value="">None Selected</option>
</select>
What i want to do is simple: I'm using json2html to add items to this select tag from the data, and the option value has the CODE from data. So, what i expected to happen is:
<select id="mySelectID" name="select" class="main-form">
<option value="1">Some Data 1</option>
<option value="2">Some Data 2</option>
</select>
by doing this:
var jsonData = $.parseJSON(window.localStorage.getItem("data"));
var transform = {tag:'option', id:'.CODE',html:'{$NAMEVAR}'};
document.getElementById('mySelectID').innerHtml = json2html.transform(jsonData,transform);
But this does not work, and i know it won't. The problem is that i do not know how to insert this JSON into options to my HTML. I thought that json2html could help me, but as i do not speak English natively, it's kinda of being hard for me to understand that, and I'm also new to JavaScript.
Thanks!
You don't need the transform for this, try it this way:
var jsonData = $.parseJSON(window.localStorage.getItem("data"));
var $select = $('#mySelectID');
$(jsonData).each(function (index, o) {
var $option = $("<option/>").attr("value", o.CODE).text(o.NAMEVAR);
$select.append($option);
});
Here is a working fiddle.
