sat 它的元素 name

这是我的代码: var satellitesData = fileData.find('sat[name='+satName+']');

var satellitesData = $(fileData).find('sat[name='+satName+']');

var satellitesData = fileData.find('sat[name='+satName+'] > transponder');

var satellitesData = fileData.find('sat[name='+satName+']').innerHTML;

name querySelector 而不是 .find 用于jquery或普通的javascript数组,但不用于javascript htmlelements)。

const satName = "NSS 9/Yamal 300K (177.0W)";
const satellites = document.querySelector('satellites');
const satellitesData = satellites.querySelector('sat[name="' + satName + '"]');
console.log(satellitesData);
