如何使用 ajax 和本地 JSON 文件将数据 POST 到网页？

发布于 2025-01-11 04:37:38 字数 5226 浏览 0 评论 0原文

我正在尝试通过使用 ajax 在 html 网页的输入字段中输入信息以及已经具有现有信息的本地 JSON 文件来更新列表，所有文件都与 .html 文件位于同一目录中。

该对象有 3 个属性：1. 名称，2. 物种，3. 最喜欢的食物。

我输入的信息应显示在“现有宠物”标题中。

这是 html 文档：

这是 .js 文件：

$(function () {
    var $data = $('#pets');
    var $name = $('#name');
    var $species = $('#species');
    var $favfood = $('#favfood');
    $.ajax({
        type: 'GET',
        url: '/animals-1.json',
        success: function (data) {
            $.each(data, function (i, newOrder) {
                $data.append('<li><a class="font-weight-bold">Name: </a>' + newOrder.name + ', <a class="font-weight-bold">Species: </a>' + newOrder.species + ', <a class="font-weight-bold">Favorite Food: </a>' + newOrder.favfood + "</li>");
            });
        },
        error: function () {
            Swal.fire({
                title: 'Error!',
                text: 'Your request could not be processed',
                icon: 'error',
                confirmButtonText: 'Ok'
            })
        }
    });
    $("#addpets").click(function(){

        var newp = {
            name: $name.val(),
            species: $species.val(),
            $favfood: $favfood.val(),
        };
        $.ajax({
            type: 'POST',
            url: '/animals-1.json',
            data: newp,
            success: function(newpts){
                $data.append('<li><a class="font-weight-bold">Name: </a>' + newpts.name + ', <a class="font-weight-bold">Species: </a>' + newpts.species + ', <a class="font-weight-bold">Favorite Food: </a>' + newpts.favfood + "</li>");
            },
            error: function(){
                Swal.fire({
                    title: 'Error!',
                    text: 'Your request could not be processed',
                    icon: 'error',
                    confirmButtonText: 'Ok'
                })  
            }
        });
    });
});

moveover，JSON 文件中的数据：

[
  {
    "name": "Meowsy",
    "species" : "cat",
    "favfood": "tuna"
  },
  {
    "name": "Barky",
    "species" : "dog",
    "favfood": "carrots"
  },
  {
    "name": "Purrpaws",
    "species" : "cat",
    "favfood": "mice"
  }
]

我已经仔细检查了 JSON 文件的名称目录等。

原文

I'm trying to update a list by entering information into the input fields of the html webpage using ajax alongside a local JSON file which already has existing information, all the files are in the same directory as the .html file.

The object has 3 attributes: 1. Name, 2. Species, 3. Favorite Food.

The information I enter should display in the "Existing Pets" heading.

this is the html doc:

This is the .js file:

            });
        },
        error: function () {
            Swal.fire({
                title: 'Error!',
                text: 'Your request could not be processed',
                icon: 'error',
                confirmButtonText: 'Ok'
            })
        }
    });
    $("#addpets").click(function(){

        var newp = {
            name: $name.val(),
            species: $species.val(),
            $favfood: $favfood.val(),
        };
        $.ajax({
            type: 'POST',
            url: '/animals-1.json',
            data: newp,
            success: function(newpts){
                $data.append('<li><a class="font-weight-bold">Name: </a>' + newpts.name + ', <a class="font-weight-bold">Species: </a>' + newpts.species + ', <a class="font-weight-bold">Favorite Food: </a>' + newpts.favfood + "</li>");
            },
            error: function(){
                Swal.fire({
                    title: 'Error!',
                    text: 'Your request could not be processed',
                    icon: 'error',
                    confirmButtonText: 'Ok'
                })  
            }
        });
    });
});

moveover, data in the JSON file:

[
  {
    "name": "Meowsy",
    "species" : "cat",
    "favfood": "tuna"
  },
  {
    "name": "Barky",
    "species" : "dog",
    "favfood": "carrots"
  },
  {
    "name": "Purrpaws",
    "species" : "cat",
    "favfood": "mice"
  }
]

I've double checked the name directory etc of the JSON file.
