动态将表单ID传递给函数

我在页面上有几种形式,我想利用相同的ajax函数。因为我使用getElementById来获取id,然后将其传递给我的ajax函数,所以它对于一种形式非常有用。我想做的是动态地传递表单onSubmit的ID。

表格

<form id="postData" name="business" method="post" action="{{ path('location_graph', {'location_id': location.getId }) }}"
      class="m-form m-form--fit m-form--label-align-right">
    <div class="form-group m-form__group row">
        <label class="col-2 col-form-label required" for="description">Business
            Description</label>
        <div class="col-7">
            <input type="text" class="form-control m-input" id="description"
                   name="extra[description]">
        </div>
    </div>

    ...

    <div class="form-group m-form__group row">
        <button type="submit" class="btn m-btn--square btn-outline-primary">
            Submit
        </button>
    </div>
</form>

脚本

document.getElementById('postData').addEventListener('submit', postData);

function postData(event) {
    event.preventDefault();

    $.ajax({
        type: $(this).attr("method"),
        url: $(this).attr("action"),
        data: $(this).serialize(),
        success: function (data) {
            console.log(data);
            $('#success__para').html("You data was saved");
        }
    });
}

您可以将submit事件处理程序附加到每个表单,并将eventthis.id(表单元素的id)作为参数传递。

Javascript:

function postData(event, id) {
    event.preventDefault();
    var elem = $('#'+id);
    $.ajax({
        type: elem.attr("method"),
        url: elem.attr("action"),
        data: elem.serialize(),
        success: function (data) {
            console.log(data);
            $('#success__para').html("You data was saved");
        }
    });
}

HTML:

<form id="someid" onsubmit="postData(event, this.id)">
