问题描述
我正在Stackblitz中工作，我的文件之一是带有一些数据的JSON文件.我想将此JSON数据放入我的JavaScript文件index.js中.但是如何?
I'm working in Stackblitz and one of my files is a JSON file with some data. I want to get this JSON data into my javascript file index.js. But how?
当我尝试用xhr加载它时，就像这样:
When I try loading it with xhr, like this:
function loadJSON(callback) {
var xobj = new XMLHttpRequest();
xobj.overrideMimeType("application/json");
xobj.open('GET', './data.json', true); // Replace 'my_data' with the path to your file
xobj.onreadystatechange = function () {
if (xobj.readyState == 4 && xobj.status == "200") {
// Required use of an anonymous callback as .open will NOT return a value but simply returns undefined in asynchronous mode
callback(xobj.responseText);
}
};
xobj.send(null);
}
loadJSON( (res) => {
console.log('res', res);
});
我在控制台中看到以下内容
I get the below in my console
res
