Bootstrap $('#myModal').modal('show') is not working

Question

I'm not sure why but all the modal functions are not working with me. I checked the version and the load they are fine.

I keep getting this error message:

Uncaught TypeError: $(...).modal is not a function

for the hide I already found an alternative. instead of:

$('#myModal').modal('hide');

I used this :

$('#myModal .close').click();

And it works perfectly.

The problem now is with the show

$('#myModal').modal("show");

I also tried both

$('#myModal').modal("toggle");

And:

$('#myModal').modal();

but unfortunately none of them is working.

Here html code -when the button is clicked I will do some verification and handle a json data from the web service if it succeed then I want show my modal- everything is working except the show.

 <button type="button" id="creatNewAcount" class="btn btn-default" data-toggle="modal">Sign up</button>

if there's any alternative I would like to know it.

Most common reason for such problems are

1.If you have defined the jquery library more than once.

<script type="text/javascript" src="//code.jquery.com/jquery-1.11.3.min.js"></script>
<script src="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/js/bootstrap.min.js"></script>

    <div class="modal fade" id="myModal" aria-hidden="true">
    ...
    ...
    </div>

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.0/jquery.min.js"></script>

The bootstrap library gets applied to the first jquery library but when you reload the jquery library, the original bootstrap load is lost(Modal function is in bootstrap).

2.Please wrap your JavaScript code inside

$(document).ready(function(){});

3.Please check if the id of the modal is same

as the one you have defined for the component(Also check for duplication's of same id ).

Solution 2

<div class="modal fade" id="myModal" aria-hidden="true">
   ...
   ...
</div>

Note: Remove fade class from the div and enjoy it should be worked

Solution 3

This can happen for a few reasons:

1. You forgot to include Jquery library in the document
2. You included the Jquery library more than once in the document
3. You forgot to include bootstrap.js library in the document
4. The versions of your Javascript and Bootstrap does not match. Refer bootstrap documentation to make sure the versions are matching
5. The modal <div> is missing the modal class
6. The id of the modal <div> is incorrect. (eg: you wrongly prepended # in the id of the <div>)
7. # sign is missing in the Jquery selector

Solution 4

I got same issue while working with Modal Popup Bootstrap , I used Id and trigger click event for showing and hidding modal popup instead of $("#Id").modal('show') and $("#id").modal('hide'), `

    <button type="button" id="btnPurchaseClose" class="close" data dismiss="modal" aria-label="Close"> <span aria-hidden="true">×</span></button>
<a class="btn btn-default" id="btnOpenPurchasePopup" data-toggle="modal" data target="#newPurchasePopup">Select</a>
    $('#btnPurchaseClose').trigger('click');// for close popup

     $('#btnOpenPurchase').trigger('click');`// for open popup

Solution 5

My root cause was that I forgot to add the # before the id name. Lame but true.

From

$('scheduleModal').modal('show');

To

$('#scheduleModal').modal('show');

For your reference, the code sequence that works for me is

<script>
function scheduleRequest() {
        $('#scheduleModal').modal('show');
    }
</script>
<script src="<c:url value="/resources/bootstrap/js/bootstrap.min.js"/>">
</script>
<script
    src="<c:url value="/resources/plugins/fastclick/fastclick.min.js"/>">
</script>
<script
    src="<c:url value="/resources/plugins/slimScroll/jquery.slimscroll.min.js"/>">
</script>
<script
    src="<c:url value="/resources/plugins/datatables/jquery.dataTables.min.js"/>">  
</script>
<script
    src="<c:url value="/resources/plugins/datatables/dataTables.bootstrap.min.js"/>">
</script>
<script src="<c:url value="/resources/dist/js/demo.js"/>">
</script>

You need to load jQuery first then jQuery UI/Bootstrap modal afterwards. Are you sure it's being loaded in that order?

[Nysa]

are not they ?! <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.0/jqu‌​ery.min.js"></script‌​> <script src="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/js/boots‌​trap.min.js"></scrip‌​t> <link rel="stylesheet" href="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/boo‌​tstrap.min.css"/>

It is not possible to answer unless you put your code

[MortenMoulder]

Try a newer version of jQuery. 1.12 is quite old.

[Nysa]

I'm sure, because as I mentioned the same thing happened with the hide but when I replaced it with the one that I have found It worked so I'm hoping for a replacement for the show.

[u.unver34]

Probably you are woring on WP. About jQuery 1.12 and WP issue you can check out this: wordpress.stackexchange.com/questions/244537/…

[Nysa]

I don't want call it immediately.

[Rhega]

the question is... are you using ajax to do some verification and for any result you want to show it on modal popup ?

[Nysa]

I want to do that but not immediately I have some code and if this code generate the correct result then the modal should appear if not it will not appear.

[Nysa]

no I don't want to show the result in the modal. I want the modal to be shown in some cases depending on the result .

[Rhega]

I update my answer... or if still not working, can you show us that generate code ?

[Nysa]

OMG It worked. finally found the duplicated one in the middle. I have been searching in my code since you posted your answer. thank you so much you really helped me. I'm really happy.

[Alfiza malek]

Could ypou please share the reason behind removing fade class.It was working with fade class in all most system but facing and issue on one perticular system and tried after removing fade class and get working.

[Jerry]

@Rafikmalek I believe it is due to having another fade class somewhere overriding the fade class here. Removing should it just remove the special effects while keeping the functionality.

[Heretic Monkey]
