Question

Is it possible to link to a modal and execute a function simultaneously within the Bootstrap framework?

I have created an HTML form that looks like this:

<form class="well span9 offset1" action="/summary/" method="post">
    {% csrf_token %}
        <fieldset>
        <label class="control-label" for ="inputIcon">Type or paste your text into box:</label>
        </fieldset>
        <div class="controls">
            <div class="input-prepend">
                <textarea rows="15" class="span9"></textarea> 

            </div>
            </div>


        <fieldset>
        <input type="checkbox" name="input_text" />
        Send me the copy of summary by e-mail.

        </fieldset><br />
        <a href="#summaryModal" data-toggle="modal"><button type="submit" class="btn btn-primary offset3">Summarize</button></a>
    <button type="reset" class="btn btn-danger">Reset</button>
</form>

When a user submits the form, I want it to process in the summary function and return the result to a function in a Bootstrap modal. However, instead of going to the function, the form just opens the modal popup. I am trying to return to the same template from the function with the result. Do I need to use Ajax for this?

Answer №1

If you have your JavaScript functions in place, you'll need to use AJAX for this to function correctly. Follow these steps:

Ensure that your button's syntax resembles:

<button type="button" class="btn btn-primary offset3"
onClick="summaryFunction()">Summarize</button>

When the button is clicked, trigger a JavaScript function (let's call it summaryFunction()).
The function should send the form details to a PHP page that returns data in JSON format. (Refer to this for assistance)
Use $('#divId').innerHTML to populate the modal window's content with the data returned by the PHP page.
Show the modal window using $('#divId').modal();

I hope this explanation is helpful.

For example: Let the button execute a JavaScript function named summaryFunction() using the above syntax. The JavaScript function will appear like this:

<script>
function summaryFunction(){
$text = $('#textAreaId').val();
$.post("test.php", { "postedText": text },
function(data){
$('#modalInnerDiv').innerHTML = data.response;
$('#summaryModal').modal();
}, "json");
}
</script>

Remember to assign an ID to your textarea element. Replace test.php with your own PHP file. It should be expecting a posted value named 'postedText'. Organize your response into an array with key "response". For instance,

$reply = array("response" => $response)

, then convert it into JSON using json_encode(). Your PHP file should echo this JSON value.

Have an empty div within your modal with the ID #modalInnerDiv. The content of this div will be filled with the response from the PHP page and displayed within a modal window.
