[英]Trying to shorten the response I am getting from a API call
我试图缩短对日期字段的响应，只是为了仅以正确的格式读取日期而没有时间。 有没有人知道我该怎么做？
目前正在输出什么：El Cajon (2020-02-04 21:00:00) 我的目标是：El Cajon (02-04-2020)
这很棘手，因为它在一个函数内。
$(document).ready(function() { $('#submitWeather').click(function() { var city = $('#city').val(); if (city != '') { $.ajax({ url: 'https://api.openweathermap.org/data/2.5/forecast?appid=34fd31758b449ea433e05058c225793c&q=' + city + "&units=imperial&count=10", type: "GET", dataType: "jsonp", success: function(data) { var widget = show(data); $("#show").html(widget); $("#city").val(''); } }); } else { $("#error").html('Field cannot be empty'); } }); }); function show(data) { return data.city.name + ' (' + data.list[0].dt_txt + ') </h3>' + '<p><strong>Temp: </strong>' + data.list[0].main.temp + ' degrees</p>' + '<p><strong>Humidity: </strong>' + data.list[0].main.humidity + ' degrees</p>' + '<p><strong>Wind Speed: </strong>' + data.list[0].wind.speed + ' MPH</p>'; } function show1(data) { return data.city.name + ' ' + data.list[0].dt_txt + ' </h3>' + '<p><strong>Temp: </strong>' + data.list[0].main.temp + ' degrees</p>' + '<p><strong>Humidity: </strong>' + data.list[0].main.humidity + ' degrees</p>' + '<p><strong>Wind Speed: </strong>' + data.list[0].wind.speed + ' MPH</p>'; } console.log('hello')

对我来说，它看起来像日期和时间，因此您可以将其转换为日期const date = new Date(data.list[0].dt_txt)然后获取然后根据需要对其进行格式化，或者如果您只想摆脱时间， data.list[0].dt_txt.split(' ')[0]将在空间之前占据所有。
这是关于日期 API 的一切： https : //developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date
