[英]Difference between form.submit() and having an input with type of “submit”
[英]Any difference between an <input type=“submit”> button and and javascripts .submit()
我正在嘗試使用隱藏值(這是循環的當前迭代)將表單提交到Web服務器。
<form id="question_id_to_delete" action = "{{url_for('delete_question')}}" method="post">
<input type="hidden" name=id value={{entry.id}}>
<input type="submit">
</form>
當我使用提交按鈕時,一切正常。 我試圖通過單擊包含希望用戶能夠單擊的字符串的div來模仿此行為。
<div id="question" onclick="document.getElementById('question_id_to_delete').submit()"> {{entry.question}} </div>
此onclick事件始終發送帶有最后迭代ID的表單(如果我的頁面上有五個元素,則entry.id將始終作為五個元素發送)。
我可以通過使用div click事件或某種不涉及按鈕的jQuery事件來模擬Submit按鈕的行為的任何方式都很好。 我正在使用Jinja 2模板(Flask框架)。 謝謝!
我循環瀏覽“條目”以發布到主頁上。
{% for entry in entries %}
<form id="delete_question" ...>
{% endfor %}
我更改了表單ID,以將循環的當前迭代附加到每個表單的ID。
<form id="delete_question_{{entry.id}}" ...>
這是更正后的來源,包括具有click事件的div。
{% for entry in entries %}
<form id="delete_question_{{entry.id}}" action ="{{url_for('delete_question')}}" method="post">
<input type="hidden" name="id_to_delete" value={{entry.id}}>
</form>
<div id="question" onclick=document.getElementById("delete_question_{{entry.id}}").submit() >
<li><h2>{{entry.question}}</h2>
</div> {% endfor %}}
<form id="question_id_to_delete" action="{{url_for('delete_question')}}" method="post">
<input type="hidden" name=id value={{entry.id}}>
<div class="special-submit-button"></div>
</form>
<script>
// include jQuery before this script tag
$('.special-submit-button').on('click', function(e) {
// DIV button livs inside the form. so find the form and submit it
// doing it this way, makes this code more universal. you can now port this
// to OTHER FORMS that use the same idea, without having to change it
// simply by applying the special-submit-button class to the submitter div.
// this IS an answer.
$(this).closest('form').submit();
});
</script>
