Ajax发布请求(HTML到Express应用程序)不起作用 [英] Ajax post request (HTML to Express app) not working
问题描述
我正在构建一个用于存储配方的节点快速应用程序.通过新配方" html表单,用户可以根据需要添加任意数量的成分,这些成分通过jquery动态显示并存储在成分"数组中.因为无法通过HTTP发送此数组,所以我试图通过AJAX发布请求发送新的配方对象.我在AJAX方面的经验有限,我无法理解为什么发帖请求根本无法正常工作.这是我的前端jquery:
I am building a node express app for storing recipes. Via a 'new recipe' html form, users can add as many ingredients as they need, which are dynamically displayed via jquery and stored in an 'ingredients' array. Because I can't send this array via HTTP, I'm trying to send a new recipe object via an AJAX post request. I have limited experience with AJAX, and I cannot understand why the post request is not working at all. Here's my front end jquery:
script type="text/javascript">
//$(document).ready(() => alert("Jquery works!"));
$(document).ready(() => {
$("#addIngBtn").click(() => {
let ingredient = $("#ingredient").val();
let quantity = $("#quantity").val();
$("#ingredient").val(""); //reset ingredient input
$("#quantity").val("");
$("ul").append(
"<li>" + ingredient + " - " + quantity + "</li>"
);
});
})
$("#newRecipeForm").submit(() => {
event.preventDefault();
var ingredients = [];
$("#ingredientListUL li").each((index, element) =>
ingredients.push($(element).text())
)
var recipe = {
name: $("#name").val(),
image: $("#image").val(),
oneLiner: $("#oneLiner").val(),
method: $("#method").val(),
ingredients: ingredients
}
$.ajax({
url: "/recipes",
type: "POST",
dataType: "json",
data: recipe,
contentType: "application/json",
complete: function () {
console.log("process complete");
},
success: function (data) {
console.log(data);
console.log("process success");
},
error: function () {
console.log(err);
}
})
})
还有我的后端:
// note, this is in router file where default route "/" is equivalent to "/recipes"
router.post("/", (req, res) => {
console.log(req.body.recipe);
})
我在做什么错了?
推荐答案
这里不是专家,但是您发送的数据不包含配方密钥.在您的后端(哈哈)尝试
Not an expert here, but the data your are sending doesn't contain the recipe key. In your backend (haha) try
router.post("/", (req, res) => {
console.log(req.body.name);
})
