    jquery - How to get django form value in javascript without saving it into model - Stack Overflow

    programmeradmin4浏览0评论

    I created a django form and I need not to save those values in my database. But I don't know how to access those form values in javascript.

    balance.html

    <script>
$(document).ready(function () {
    $('.dateinput').datepicker();
    var a = document.getElementsById("{{ form.start_date }}").val;
    alert(a);
});
</script>   

<div>
    <form action="" method="POST">{% csrf_token %} Start Date: {{ form.start_date }}&nbsp;&nbsp; End Date:{{ form.end_date }}
        <br/>
        <input type="submit" name="submit" value="See Results" id="tryonce">
    </form>
</div>

    But I can't get the result. How those form value can be retrieve in javascript ?

    Reset to default 11

    The {{ form.start_date }} expands to:

    <input id="id_start_date" type="something">

    You can always right-click and inspect the element in most of the modern browsers.

    So use:

    var a = document.getElementsById("id_start_date").val;

    I suggest you use the jQuery version:

    var a = $("#id_start_date").val();

    try this also if you want to directly get values 

    var start_date="{{ form.data.start_date }}"

    The form is rendered automatically as valid html. You can access form fields by their id using the prefix id_field_name. So start_date field has id id_start_date:

    var a = document.getElementsById("id_start_date").val;

    You should read documentation on form rendering here
