how to store the select options value and text in

Question

I have a select list (sample below). I want to store this select list (text and value) in a JSON object or Array object. So that i can later go thru it using .each function. I want to then show/hide the records in the select option list based on user input. all code is ready and working except that I am not able to figure how to store a select option list with all its text and value pairs into an either Array or JSON object and subsequently able to walk thru it based on text.

thank you.

 <select id="mySelect" multiple="multiple">
    <option value="1">First</option>
    <option value="2">Second</option>
    <option value="3">Third</option>
    <option value="4">Fourth</option>
 </select>

Answer 1

My answer is very similar to @topek's but I'm using object to store array elements so it may be useful. You can inspect working example here.

HTML:

<select id="mySelect" multiple="multiple">
  <option value="1">First</option>
  <option value="2">Second</option>
  <option value="3">Third</option>
  <option value="4">Fourth</option>
</select>

Javascript:

var options = [];
$('#mySelect option').each(function() {
    options.push({ "id" : this.value, "text" : this.textContent });
});

Answer 2

You can try this fiddle:

HTML

<select id="mySelect" multiple="multiple"> 
    <option value="1">First</option>
    <option value="2">Second</option>
    <option value="3">Third</option> 
    <option value="4">Fourth</option>
</select>

JAVASCRIPT

var options = {};

$('#mySelect option').each(function(){
    options[$(this).text()] = $(this).val();
});

console.log(options);

//or the other way round

var options2 = {};

$('#mySelect option').each(function(){
    options2[$(this).val()] = $(this).text();
});

console.log(options2);

Console Log Output:

Object
First: "1"
Fourth: "4"
Second: "2"
Third: "3"
__proto__: Object
