Get value from input in model

Asked 28/8, 2015 at 16:1 Answered 16/8, 2022 at 13:41

I have a bootstrap model and inside I have an input field.

<input type="text" name="quota" class="form-control" id="quotas" value="'.$storagequota.'" maxlength="20" >

Also, I have a button which when clicked calls a function so I can get the value of the input field.

function getQuota(){
    quota = $("#quotas").val();
    alert(quota);
}

The problem is that I cannot get the value that user typed. The weird thing is that i have another model in another page that works in the same way. Can someone help with that? Thanks in advance.

is there multiple elements with same ID quotas in your page? – Zipper 28/8, 2015 at 16:13

Just put the id of the modal before the id of the input

$("#registration_modal #useremail").val().trim()

This should be the top answer. It worked just as I suspected. Thank you! – Fabria 16/12, 2019 at 6:13

Your code is correct .

Just write the JS function in head tag.

Here is your code

<html>    
<head>
    <script>
        function testFun() {
            quota = $("#quotas").val();
            alert(quota);
        }
    </script>
</head>

<body>
    <div id="admin" class="modal fade" role="dialog">
        <div class="modal-dialog">
            <!-- Modal content-->
            <div class="modal-content  animated bounceInDown">
                <div class="modal-header">
                    <button type="button" class="close" data-dismiss="modal">&times;</button>
                        <h4 class="modal-title">Settings</h4>

                </div>
                <div class="modal-body">
                    <ul class="nav nav-tabs">
                        <li class="active"><a href="#tab1" data-toggle="tab">Quota</a>

                        </li>
                    </ul>
                    <div class="tab-content">
                        <div class="tab-pane active" id="tab1">
                            </br>
                            <div id="table" class="col-lg-12"></div>
                            <label for="Quota">Quota</label>
                            <div class="input-group form-group">
                                <input type="text" name="quota" class="form-control" id="quotas" value="10" maxlength="20">
                                <div class="input-group-addon input-group-btn-custom "> <span id="type">Gb</span> 
                                </div>
                            </div>
                        </div>
                        </br>
                        </br>
                        <button type="submit" class="btn btn-primary" onclick="testFun()" id="admin">Submit</button>
                    </div>
                </div>
                <div class="modal-footer">
                    <button type="button" class="btn btn-danger" data-dismiss="modal">Close</button>
                </div>
            </div>
        </div>
    </div>
</body>

</html>
