How to set materialize multiselect selected values from jquery - materialize

Question

I want to set values as selected at initial loading of my page but I'm not able to set them.
Here is my HTML markup:
<select multiple id="access_rights">
<option value="default" disabled selected>Choose your options</option>
<option value="create">Create</option>
<option value="read">Read</option>
<option value="update">Update</option>
<option value="delete">Delete</option>
</select> <label>Select Access Rights</label>`
Now I want 'Create' and 'Update' as default selected at first loading of page.
How can I do that?

Answer 1

See Working Demo :
$(document).ready(function() {
$('select').material_select();
});
var selectedOptions=[
"create",
"update"
];
$.each(selectedOptions, function(i,e){
$("#access_rights option[value='" + e + "']").prop("selected", true);
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/materialize/0.100.2/css/materialize.min.css">
<script src="https://cdnjs.cloudflare.com/ajax/libs/materialize/0.100.2/js/materialize.min.js"></script>
<label for="access_rights">Select Access Rights</label>
<select id="access_rights" multiple>
<option value="default" disabled>Choose your options</option> <option value="create">Create</option> <option value="read">Read</option> <option value="update">Update</option> <option value="delete">Delete</option> </select>

Answer 2

Just use selected in create and update option. For Ex:-
<select multiple id="access_rights">
<option value="default" disabled>Choose your options</option>
<option value="create" selected>Create</option>
<option value="read">Read</option>
<option value="update" selected>Update</option>
<option value="delete">Delete</option> </select>
<label>Select Access Rights</label>

$( document ).ready(function() {
$(".select-wrapper").each(function() {
var wrapper = this;
$(this).find("ul>li").each(function() {
var li = this;
var option_text = $(this).text();
$(wrapper).find("select option:selected").each(function() {
var selected_text = $(this).text();
if(option_text == selected_text) {
//$(li).addClass("active selected");
//$(li).find("input").prop('checked', true);
$(li).click();
}
});
});
});
});
