两个人以一种形式提交提交输入并在Ajax中提交

问题描述

这是我第三次提出这个问题,很遗憾,没有专家可以回答这个简单的问题.

This is the third time I ask this question, unfortunately there is no expert who can answer this simple question.

如果没有javascript代码,view.py中的方法对于保存和计算均适用,两个提交一个表单即可.但是,当我使用ajax时,它会失败(由于e.preventDefault();),这是我的代码:

Without javascript code the method within view.py works perfectly both for save and calc, two submit for one form. However when I use ajax, it fails (because of e.preventDefault();), here is my code:

html

<form method="post" id="idForm" name="fmr1" action = "/myproject/save/"
enctype="multipart/form-data">
....
<input type="submit" name="save" value="Save">
<input type="submit" name="calc" value="Calculate">
</form>

js

$("#idForm").submit(function(e) {
    e.preventDefault(); // avoid to execute the actual submit of the form.
    var frm = $('#idForm');

$.ajax({
    type: frm.attr('method'),
    url: frm.attr('action'),
    data: frm.serialize(),
    success: function (data) {
        alert(data.mylist)
    },
    error: function (data) {
        alert("ajax fails")
    }
    });

});

观看次数

if request.method == 'POST' and 'calc' in request.POST:
    print("runs calc form")
    mylist= [5]
    return JsonResponse({'mylist':mylist})

问题

现在,问题出在request.POST中的'calc'"中,因此当我向表单添加ajax或id ="idForm"时,它无法运行.

Now the difficulty is in "'calc' in request.POST", so it does not run when I add ajax or id="idForm" to the form.

我还需要运行保存",因此我需要在request.POST中添加"calc".

I need "'calc' in request.POST" since I have to run "save" as well.

两者都必须在视图的一个方法中运行.

Both will have to run inside one method in views.

javascript(e.preventDefault();)阻止其正常运行的原因可能是什么?

What can be the reason that javascript (e.preventDefault();) prevents it from running correctly?

如何解决?

推荐答案

因为没有人回答这个问题.使用ajax时,两个按钮的一种形式不起作用,我使用了一个按钮和一个输入:

Since no one answered this question. With ajax two button one form did not work, I used one button and one input:

    <input type="submit"  name="save" id="save" value="Save">
    <button type="button" onclick="sendData()">Calculate</button>

这对我有用.在视图中,我实现了两种方法.

this worked for me. In views I implemented two methods.
