Topic: Set Selected Value in Select via js/jq

Guasy free asked 4 years ago

Hello Im working in my 1st project using mdb jq.

I have 2 selects in a single form. One for timezones and one for User Roles

I have been trying to select a default value when the page renders but i cant find a way.

<script>
 $(document).ready(function () {
$('.mdb-select').material_select();
    $("select#Role").val("Admin");
    $("select#TimeZone).val("Pacific Standard Time");
});
<script>

i have tried to use the $(".select-dropdown")

but since its not a single select i cant achieve it. Can you help me please?

Ok, i edited it. But the problem is that it selects the value but the text is empty

$("select#IdFlotilla").attr("selected", false);
$("select#IdFlotilla option[value=3]").attr("selected", true);

No Text Selected Selected value but no text

Tomek Makowski staff answered 4 years ago

Hi

$("select#IdFlotilla").find("[selected]").attr("selected", false);
$("select#IdFlotilla").find("option:contains('3')").attr("selected", true);

This code never choose your third option, becouse contains('some text') is responsible for selecting elements which contains text eg. 'some text' here. If you want to choose third option try this out option:eq(3).

Ok. Well show me this snippet (Version of snippet must be 4.8.2) and show me screen shot of your scripts initialization in file. Please describe your problem in details and I'll try to help you.

Perhaps, try to update your library

I have MDB 4.8.2, and the snippet version is 4.8.1, could this be the problem? I updated to 4.8.2 because the select had a false double click, maybe something changed and the script dont work anymore for that version.

Ok, it works in the snippet, but in my project it doesnt.

I only have bootstrap, jquery, jqueryval and MDB libraries. Can this be a problem of some library?

Tomek Makowski staff answered 4 years ago

Hi

Check this out

<script type="text/javascript">
$(document).ready(function () {
  $('.mdb-select').materialSelect();
  $("select#Role").find("[selected]").attr("selected", false);
  $("select#Role").find("option:contains('option 1')").attr("selected", true);
});

Best regards

Hi Tomek,

For me, this solution works as long as the user hasn't touched the select.But once the user has manually selected an option, setting it with javascript no longer seems to work. Do you have any fix for that?

Thanks!

Laurens Swart

EDIT: found it in another topic: $(select-element-id).prevAll(".select-dropdown").children("li:contains('option value')").trigger("click");

Hi Lauren,

I'm happy that you have found the solution for that :)

Keep coding,
