Question

我是MVC的新手，并且尝试从最近7个小时将值从viewBag传递到MVC 5中的javascript函数。我有一个字符串变量

file = open("somefile.txt", "w")
subprocess.run(["df","-h"], stdout = file)
os.system("gnome-terminal -e 'gedit somefile.txt' ")

我将它传递给查看并将其存储为隐藏元素

ViewBag.c1 = "0.30"

然后我想在后面的js函数

中访问这个隐藏元素的值

@Html.Hidden("Superman", (string)ViewBag.c1)

Answer 1

@Html.Hidden("Superman", (string)ViewBag.c1)


function getValue1() {
  return parseFloat($("#Superman").val());
}

//or

function getValue1() {
  return parseFloat(document.getElementById("Superman").value);
}

Answer 2

var c1Value = "@Html.Raw(ViewBag.c1)";

function getValue1() {
  return parseFloat(document.getElementById(c1Value).value);
}

Answer 3

您可以将视图包值存储在JavaScript变量中，如下所示。

import numpy as np
import pandas as pd

result = pd.DataFrame()
origDict = np.load("Hannah Lee.npy")
for item in range(len(origDict)):
    newdict = {(k1, k2):v2 for k1,v1 in origDict[item].items() for k2,v2 in origDict[item][k1].items()}
    df = pd.DataFrame([newdict[i] for i in sorted(newdict)],
                      index=pd.MultiIndex.from_tuples([i for i in sorted(newdict.keys())]))
    print(df.bun)
