使用js-yaml这个js库进行json和yaml转换

在线DEMO

效果

json转yaml

function toYaml() {    let json = area_json.innerText;    if (json) {        try {            let jsonObj = JSON.parse(json);            area_yaml.innerHTML = hljs.highlight("yaml", jsyaml.dump(jsonObj)).value;            area_json.innerHTML = hljs.highlight("json", json).value;        } catch (e) {            alert(e)        }    }}

yaml转json

function toJson() {    let yaml = area_yaml.innerText;    if (yaml) {        try {            let json = JSON.stringify(jsyaml.load(yaml), null, 2);            area_json.innerHTML = hljs.highlight("json", json).value;            area_yaml.innerHTML = hljs.highlight("yaml", yaml).value;        } catch (e) {            alert(e)        }    }}
