I have a simple JSON code:
[{'1':'Name'}, {'2', 'Age'}, {'3','Gender'}]
I have a select tag in my HTML:
<select name="datas" id="datas"></select>
I need a simple way to create HTML select box from this JSON, like this:
<select name="datas" id="datas">
<option value="1">Name</option>
<option value="2">Age</option>
<option value="3">Gender</option>
</select>
Just for kicks here is an answer in pure javascript, also you probably do not need an array for this just a simple object will suffice
<select name="datas" id="datas"></select>
<script>
html = "";
obj = {
"1" : "Name",
"2": "Age",
"3" : "Gender"
}
for(var key in obj) {
html += "<option value=" + key + ">" +obj[key] + "</option>"
}
document.getElementById("datas").innerHTML = html;
</script>
key and obj[key] should at least be properly encoded. Imagine if obj = {"1" : "> one &","2":"This has a quote \" in it"}. It is safer to generate it using .append than joining html stringsTry this.
//Correct(missing colons) in the array items
var data = [{'1':'Name'}, {'2': 'Age'}, {'3': 'Gender'}];
Create option element and then use append method to append them into select element.
var $select = $('#datas');
$.each(data, function(i, val){
$select.append($('<option />', { value: (i+1), text: val[i+1] }));
});
The above answer assumes that the data indexes of the array are in order. What if the data variable would be:
var data = [ {'23':'Age'}, {'12':'Gender'}, {'3':'Name'}];
So in alphabetical order, but with random id's.
One way I found in solving this is:
$.each(data, function(key, value) {
var i = Object.keys(value)[0];
$("select#datas").append( $("<option />").val(i).text(value[i]) );
foreach(),document.createElement(), and.appendChild().
