Question

我正在尝试创建一个通过textarea（textarea1）获取JSON输入的表单，然后处理它并将响应打印回另一个文本区域（textarea2），同时仍然显示textarea1的原始json输入。我有代码，它接受输入计算结果并将值返回。但这些值未以新形式显示。我的服务器不使用任何型号。

以下是views.py

中的代码

from django.shortcuts import render
from django.http import HttpResponse, HttpResponseRedirect

import simplejson
import read_json
from .forms import JsonTestForm

import sys
import traceback

def index(request):
    form = JsonTestForm()
    return render(request, 'ellora/index.html', {'form': form})

def get_json_text(request):
    print "Enter method get_json_text"
    if request.method == 'POST':
        print "request method is post"
        form = JsonTestForm(request.POST)
        if form.is_valid():
            print "form is valid"
            #call the read_json.py and pass the json script in the appropriate format
            # capture the result of it in some way and then redirect it to the results page
        try:
            data_string=form.cleaned_data['jsonText']
            data = simplejson.loads(data_string)
            #do some processing of the data here
            f = open("temp/test7777777.py", "r")
            form.cleaned_data['pythonScript'] = f.read()
            return render(request, "ellora/index.html", {"form": form})
        except Exception as e:
            exc_type, exc_value, exc_traceback = sys.exc_info()
            lines = traceback.format_exception(exc_type, exc_value, exc_traceback)
            print ''.join('! ' + line for line in lines)            
            mystr = ''.join('! ' + line for line in lines)
            form.cleaned_data['pythonScript'] = mystr
            print "cleanded_data=", form.cleaned_data['pythonScript']
            return render(request, "ellora/index.html", {"form": form})
    else:
        print "request type was not POST"

来自我的forms.py

的代码

from django import forms

class JsonTestForm(forms.Form):
    jsonText = forms.CharField(label="", widget=forms.Textarea(attrs={"class": "txtarea", "placeholder": "Enter your json script here"}), initial="[]")
    pythonScript = forms.CharField(label="", widget=forms.Textarea(attrs={ "class": "txtarea", "readonly": "readonly", "rows": "1", "cols": ""}), initial="python script here")
    testLog = forms.CharField(label="", widget=forms.Textarea(attrs={ "class": "txtarea", "readonly": "readonly", "rows": "1", "cols": ""}), initial="logs here")

您需要使用AJAX。 This应该让你知道如何解决这个问题。 AngularJS还允许您轻松地执行此操作，具体取决于所需的逻辑。
